Greg OH: There is one dangerous element to the rules: the Remote ID not only tells who owns the drone, but where the operator is right now. This would allow anyone who objects to being observed to engage the operator, whether or not the operator is doing anything improper.

It might be possible to circumvent that by equipping your drone with an add-on device that transmits where it was launched from, but not where the operator is now, then moving away from that spot before flying to your destination.

There's no way I'm going to fly a drone that's broadcasting my location to anyone who might object, regardless of which of us has the law on our side.

Isn't that app called Facebook and many Dating Apps?

They tell you exactly where users are everywhere in the world once you upload and update your timelines AND they do it intentionally and users seem to be HAPPY with it!

Greg OH: 360 degree prop guards like the one shown in the video greatly reduce flight time and range. Between that and the Japan-spec battery, that compliant Mini 2 probably has 1/4 the useful range of the normal model.

I could see a market for a battery with 3/4 the normal capacity combined with an ultra-light prop guard.

Of ALL the rules I see, the prop-guard rule is the one that makes the MOST SENSE!!! Having even small props spinning at 600 RPM and faster is a recipe for disaster in cutting someone's carotid artery wide open! ALL drones should have prop guards!

The flight time issue will be a NON-ISSUE once Aluminum-Air and Aluminum-Ion batteries come out which have three to EIGHT TIMES the power capacity of Li-Ion at only twice the weight.

At the higher end of the capacity scale, we could make an Aluminum-Air battery that is half-the-size but 4x the power capacity! So you then get 2x to 4x the range of Li-Ion at half the physical volume and/or weight depending upon what parameter you want to balance most towards. (i.e. volume, weight or capacity?)

The technology is in testing NOW and is likely to be ready for market in two to four years!

sirhawkeye64: It's people like this that will eventually make it so drones are banned. I mean the various regulations are getting worse each year (more restrictive, although some are being relaxed, like the original 6-7 mile rule for airports in some areas), but still, the regulations and rules keep stacking up to a point where owning a drone is no longer a desire by many people. Too many rules because of too many idiots.

"....“Ignorantia juris non excusat” - Ignorance is no excuse in the eyes of the law. ...." is UTTER BILGE !!!!!

Do you fine a 5 year old child 25000 Euros for playing in a restricted zone? NO OF course not! Ignorance IS an excuse for some of these DUMB LAWS !!! If one cannot reasonably KNOW what is or is not allowed then IGNORANCE IS a valid excuse!!!!

I have HAD ENOUGH --- time to fire and JAIL all these n government offcials --- give them a taset of their own medicine with LIFE in maximum security prison with the killers and rapists and THEM see what its like to be a prison b(*&(*^& AND I would put their FAMILIES (parents, grandparents, spouses and children too!) in those same DECADES LONG prison sentences as a group punishment!!!!! So THEY know what is feels like to have the jackboots ON THEIR NECKS under Americas kick em when they're down legal system!

Too many rules is right and it's TIME We The People do something about it!

At least I am going to get RID of this government by buying my way into politics and FIRING ALL OF THEM GOVERNMENT EMPLOYEES including the FAA once my candidates get elected! The LESS regulation the better!

It's waaaay pasty time to REMOVE almost ALL government agencies and the police from our lives --- TIME TO FIRE THEM ALL !!!!!

Mariano Pacifico: My advise to R5 owners. Sell. Buy real video cameras that take stills not the other way around.

"....Why? You can't even buy it as Canon supply can't follow demand. My wife has been waiting for her R5 for months. I was lucky and got mine a few months ago...."

--

Sorry about that! Our aerospace company bought HUNDREDS of them online so we're probably the largest cause of the North American and European shortage of R5s.

We needed them right away and couldn't wait for Canon to let us bulk buy so bought them all up at inflated prices (i.e. still cheap for us though!). We use them in space-oriented applications. They work GREAT!

Again, Sorry about that!

BrexitDefCom3: But as it is now utterly impractical, why would you do that? Did somebody sponsor insanity, or what?

This is NOT IMPRACTICAL !!!

His solutions are GREAT and are wonders of engineering but I can offer ANOTHER engineered solution, where I can recommend a simple rectangular sealed hollow-metal heat sink block filled with cooling oil (i.e. mineral oil or 3M-brand thermal transfer fluid) pasted or held tightly onto the entire plastic back of the camera which will extend cooling of the STOCK upgraded firmware camera by about 1.5 to 4 hours hours worth of recording time. This solution will NOT void the warranty as we do not need to open the camera.

The video tells me that the thermal pad and plastic used within the interior can transfer a calculated number of Joules per Second which I can slowly re-direct into the hollow liquid filled heat sink. The thermal transfer differential between each interior plastic part allows me to calculate the optimal heat sink size for 4 hours of recording is about 4 cm thick if it covers the entire plastic area that the swivel screen takes up.

In reply to:

tvstaff: So even with the trial fix of large external cooling equipment it still overheats. Anyone going to admit it's a design flaw?

So here we go again.

I'd like a 45 to 50mp 1DXMKIV with NO VIDEO.

12 to 15fps RAW with an OVF

With EF Mount

umggc: Great post. This is a perfect example why people with technical backgrounds often blast the big camera companies, especially canon, for lack of innovation. Their designers are not really in touch with their users. This heating issue is appareantly a design flaw. Even without external cooling, the internal copper plate in this video is improving a lot. Yet canon's solution is a 20 min time limit. How lazy can they be to possibly adopt such a solution in production model!

It's not truly a design flaw as this camera is more designed for for pro STILL PHOTO photographers rather than video people. For stills people this is an IDEAL camera and I've taken it into the mountains in deep snow in super-cold northern Canada and it has worked beautifully!

For video, you can just take use a hollow dummy battery that attaches to an Anton Bauer system rigged underneath your camera cage with a slight mod to the battery door and that seems to get rid of the heat problem too!

The battery case can be used as a heat sink which takes the heat pressure off the CMOS sensor and DSP/CPU chips which are the base cause of the overheating. A dummy battery with some heat sink material in it solves most of the problem which tells me Canon just needed to add a LARGER SHEET-BASED heat sink in the back of the camera that dumps heat quickly to the camera outside via a weather-sealed solid block of metal.

Canon will fix the problem in the R5 Mk2 by adding larger heat sinks!

PortraitLover: it is amazing how people who continually don't own the camera, read some personal reviews which are glorified opinions and then provide their opinion based on that.
There is only one ticket to provide credible opinion, buy the gear , use it according to your own needs and provide a real opinion.

For those of you in Astrophotography, the QUALITY difference between the RF mount f/1.2 50mm versus the EF mount 50mm is quite substantially in favour of the Canon R5.

The 50mm and 85mm f/1.2 RF mount lenses ARE SO GOOD that if you are into astrophotography or extreme low light video/stills that YES I would have to pick the R5 over the 1DxMk3. Those two lenses alone, while quite expensive, are SUBSTANTIALLY SUPERIOR to their RF mount equivalents. I actually quite notice the sharpness difference!

If you're willing to void your warranty on the Canon R5, you can drill multiple holes into the body itself and pump cool air into it via flexible plastic tubing and reseal the hole entrances with flexible silicone to keep the weather sealing.

Pumping cool air in one end and out the other cools the R5 camera significantly and you can get unlimited shoot time. To BYPASS the 29:59 recording time limit, you can mod the BIOS file by adding some ARM-based JMP XXXX and RTN XXXX assembler commands to bypass the timecode counter comparison instructions.

Just re-upload the BIOS (remember to change the CRC aka Cycle Redundancy Checksum values to reflect the new code changes) and you can re-upload the modded camera BIOS and shoot until you run out of memory card space or external recorder room!

Hollywood types are doing this hole-drilling into R5 camera bodies now so they can shoot 8K resolution video on the Canon R5 without restrictions for B, C and D multi-angle camera coverage.

DarkShift: I don't fully understand the testing methods here. Why the camera was even allowed to cool down after 10 minutes of shooting?

What if you need to record an event continously and just can't do breaks after few minutes of recording.

So, what is the max non stop recording time (with or without battery swaps)?

I remember the OLD DAYS of Betacam SP/DigiBeta (1980's/1990's) when tapes were only 20 minutes or 30 minutes long and those well-used NiCad NP-1a/1b batteries only lasted half-an-hour or so you had to PLAN your shoots --- Ergo, PLAN your next video session so you can be prepared to quickly switch memory cards and batteries and also cover missed footage by using a SECOND CAMERA that is turned on at a different time offset by 10 minutes so the missed footage overlaps and can be edited in later!

Again, PLAN AHEAD to avoid missed shots and coverage!

29 Minutes 59 Seconds is the maximum possible single-file record time on the BOTH the R5 and R6 due to internal camera BIOS/Firmware limitations.

I actually suggest for those who DO NOT WANT to be limited by in-camera recording length issues to buy an Atomos-like external recording solution which TENDS to record in Apple Pro-Res or MP4 high bit rate for best quality. You can get a full one to four hours depending upon bought configurations.

If you live in Canada like a wintery northern Alberta or British Columbia or in Minnesota or Wisconsin where it's -20 degrees when shooting outside, you won't have an overheating problem so shoot away!

If you live in a much warmer Florida or in rainy Seattle, WA or Vancouver, BC then TYPICALLY EXPECT about a solid 20 minutes continuous video capture on BOTH the R5 and R6 at 4K resolution depending upon your bit-depth and memory card size (larger is better!)

The R5 is a decent camera, but if you don't need 8K video, the Canon 1Dx3 is a MUCH BETTER and MUCH MORE RUGGED hybrid stills/video camera.

If you absolutely MUST have 8K footage, shoot with the 1Dx3 anyways and use those fancy TOPAZ and other Image/Video Up-Rezzing software to double your resolution on each X and Y axis and double your frame rate to a full 60 fps or 120 fps. The resulting quality is MORE THAN ENOUGH (30 years of pro-level video/stills experience here!) to meet most of of your production needs.

For the BEST VALUE for money, buy better, sharper and faster lenses (i.e. ZEISS Otus) and use the Canon 1Dx3 over the R5. You could also move in closer and add more lighting if you want to SEE MORE DETAIL in your images!

Frank_BR: There are people trying to explain Sony's departure from Brazil, citing the Amazon rainforest, politics, Bolsonaro, even climate change, lol.

The subject is more complicated than it looks. Just to show that it is not a subject for amateurs, see the expected Revenue in the Digital Cameras segment in the main markets of the world in 2019:
1. China US$ 5,608m
2. United States US$ 1,407m
3. India US$ 1,214m
4. Brazil US$ 1,095m
5. Japan US$ 1,047m
source: https: //www.statista.com/outlook/15010400/115/digital-cameras/brazil#market-pricePerUnit

Statista.com data show that Brazil is a bigger market than Japan!
And that the revenue forecast for the Brazilian market in 2025 is US$ 1,397m.

In reality, for almost ANY product arena the ONLY TWO MARKETS THAT MATTER are China and the USA! for ANY company selling any sort of electronic or other consumer product China and America are the ONLY two economies that you need to invest within in order to make some SERIOUS money. Every OTHER economy can be sent to the wayside.

Those statistics above are MISLEADING as they detail overall market spending rather than individual PER CAPITA spending which shows that the USA and China outclass ALL other economies. Until per capita income rises everywhere else, China and the USA are WHERE EVERY company needs to be in order to sell products to the consumer! Brazil is just a pipsqueak ant-sized market compared to the 10,000 kg Gorillas of China and the USA!

Computers, cameras, game consoles, mobile phones, etc, etc. if you WANT to make money, you focus your marketing on China and the USA! --- The TWO RICHEST countries in the world! Everywhere else is just an afterthought.

ramaiolo: This camera is an absolute dream camera. I don't need it, and I can't handle it, but as an external observer the only problem I can see is the very poor battery life.
Sony with the battery capacity/energy management is ahed, and can be a great point of advantage in some context.
It's true that if you can spend 4700€ (with VAT in Italy, where I live) you can also buy a couple extra battery.

You can buy an Anton Bauer Battery setup like below:

https://www.bhphotovideo.com/c/product/1503698-REG/anton_bauer_8675_0160_titon_sl_240_battery.html

and run a V-Lock DC to USB convertor from the V-lock connector on the battery to the camera.

If you mount the battery in a cage on the bottom of the camera, it also gives extra weight to the Canon R5 body for better handheld stability!

To compare mAh with Watt/hours the conversion formula is (mAh) x Volts / 1000 = Watt/Hours so this means the Canon 2130 mAh at 7.2 Volt LP-E6NH battery has 15.336 watt/hours.

The Anton Bauer Battery has a 238 Watt/hours rating and running a DC to USB converter will power the Canon R5 for a long while! At 238 watt hours, you get about 15x the power time or 4800 still images or 180 minutes (3 hours) of 8K video on one Anton Bauer Battery on a best case power draw scenario (or 3900 still photos or 150 video recording minutes in worst case power draw scenario)

This WILL WORK for pro usage!

In reply to:

yoms: Are there C1, C2 and C3 modes?

I'm not quite sure but one reviewer seemed to indicate that you can upload your own LUTs which means you can just buy one of the various fancy cinema-style colour lookup tables:

https://groundcontrolcolor.com/collections/canon-luts/canon-lut-5d-mark-iv

and modify them to your hearts delight to get the Canon C3000/C700 C1, C2 or C3 equivalent wide dynamic range modes. This does mean your look will be BURNED INTO the footage during recording, but ANY decent colourist worth their salt can make a wide dynamic range LUT sing with bright beautiful colour on your final edited master render!

In reply to:

mikegt: A substantial number of reports on R5s overheating have already arrived. I'm sorry to say this but the predictions I made back in April regarding this camera being crippled by heat issues are coming true. Back then I wrote:

Since the introduction of the Canon Cinema series a decade ago Canon has never introduced a consumer model that directly competes against their expensive professional cameras. Canon has a very well established history of crippling the capabilities of their consumer cameras to protect their more expensive models. The idea that they are going to introduce something that will make their entire Cinema EOS line obsolete is just wishful thinking. Canon will do what they have always done in such situations. Canon will not permit the R5 to be a Cinema camera killer. It will be crippled by rolling shutter, over-heating in 8K mode...

Again, buy some BLUE COOLING GEL PADS from your local Dollar Store and put them in an icebox or refrigerator and wrap your camera in those and your overheating problem will go away!

Again, you can ALSO point or stick-tape a cheap and QUIET CPU fan onto the side of the R5 camera and again your heating problem goes away! It's called USE YOUR BRAIN!

I did this 30+ years ago during Betacam SP days (i.e. the 1980's) when recording tapes were only 20 minutes long and we had to PLAN our shoots and long interviews around that 20 minute tape-switch requirement! We used bigger fans to keep those cameras cool.

STOP being so lackadaisical when you can USE SOME OF THAT GREY MATTER you call a brain to SOLVE the cooling and recording limit problems! It took me barely 5 minutes to fix the heating issues with the old Sony A7s2 camera using a double-sided thermal taped CPU fan and cooling gel packs to keep our cameras cool --- I think YOU can do the same with the Canon R5 for long 8K shooting!

In reply to:

mikegt: This "review" has no actual performance testing. Canon has expressly forbid performance testing of the R5 until actual production cameras ship, and that is apparently not going to be for a few weeks yet.

Meanwhile I'm afraid that hordes of DPReview readers will succumb to the relentless hype (11 pre-release articles published all praising the R5) and put in loads of pre-orders for this $4,000 product before any actual professional reviews can appear.

Canon's own info says that this is not a camera for video professionals. They admit that the camera will over-heat and shutdown after shooting around 20 and 30 minutes, and that is at an ambient temp of only 73 degrees! In Hollywood summer days average 85 degrees or higher - the R5 there will probably only last a few minutes. Canon says that after ten minutes of being turned off, you can then shoot another 3 minutes before the camera overheats again! No professional production is going to put up with that kind of unreliability.

ALL you need to do is take a small 1/8th height aluminum CPU cooler from a computer setup (i.e. one cm in height) with a small form factor fan power by a USB port and you stick it with heat transfer tape to an open area of the left side of the R5 camera and your heating problem suddenly goes away and you can record for whatever length you like! (i.e I also just change the R5 Camera BIOS bits-and-bytes where the 16-bit, 32-bit or 64-bit time limiter code is and and that PESKY 30 minute recording time limit GOES AWAY OR I can at least set it to 99 minutes if its an actual two-byte string value using a Hex Editor and re-upload the BIOS)!

For the old Sony A7s2 heating issues, we actually wrapped the camera in cooling gel pads that were stored in a refrigerator for a few hours which kept the camera so cool we could record all day! For the R5, just buy multiple blue cooling gel pads at your local Dollar Store and cool your camera that way too!

MDRCHINA: So China, after violating virtually every foreign corporation foolish enough to set up a Presence in China, takes a CCP approved tentative step towards offering Protection to a foreign firm. What a joke. IP rights violation has been an ever tightening noose as a "price to attempt to gain entry to the **China Market**. The Party in China knows very well what it has done--for it has been done with great focus and by design-- and will no doubt attempt to keep the Fools Fooled--especially given the impending international Covid 19 backlash. I, and I am only one man with one vote (though I have lived in China for tens years, Taiwan and SE Asia for another 5 and studied the country since 1973) have long ago ceased to buy Made in China. I will only buy photo gear (and other sundry goods) from Japanese firms that operate in their own homeland, Taiwan, Thailand and the Philippines.

All my main photo and computer gear is made in CANADA !!!

The camera (we custom build those where even the lenses, coatings, sensors, DSPs, source and compiled code are fully Canadian!) Even my computer where every single component from the screws/fasteners, capacitors and resistors to the power supply, motherboard and CPU/GPU is Designed, Machined, Made and Assembled in Canada (i.e. fully ITAR-free)! Even the rare earths, metals and ceramics it's made of is ALL Canadian-sourced!

So it IS possible to buy NOT Made In China --- BUT --- you will pay for it dearly or be designing and building it yourself! Some of us like me are just picky and would rather design and build it ourselves to our own ultra-high-end specifications but that's just me!

In reply to:

HenryEckstein: Now that a Nikon P950 2000mm zoom equivalent is a big deal, can we NOW DO a real world REVIEW of the MTF Services Ltd B4 2/3" to Canon EF Adapter which allows us to put a 2/3rds inch Broadcast Video Zoom lens on an Canon EF mount camera!

See link for MTF Services Ltd B4 2/3" to Canon EF Adapter:

https://www.bhphotovideo.com/c/product/854164-REG/MTF_Services_Ltd_MTB4CANEF_B4_2_3_to_CANON.html

eBay and Amazon are now seeing LOTS of B4 mount servo zoom lenses (i.e. 12x to 20x zoom) which means the equivalent in crop-mode on say a Canon 5Dmk4 or 1Dx3 would be about 4000mm (i.e. my unconfirmed estimate!).

Try any of the HD B4-mount 2/3rds inch servo zoom lenses such as those Fujinon or Canon. They are going on average for about $3700 CAN ($3200 US) on ebay/amazon. Let's see the visual quality comparison against the typical night moon shot with one of these attached to a 5Dmk4!

v

P.S.

I should note that doing the equivalent focal length calculation of a B4 mount lens being put on the Canon EF mount with a B4-to-EF adapter on a 5Dmk4 or 1Dx2/3 series is a bit complicated because of sensor size/crop mode differences AND mount engineering issues.

BUT ...... in MY UNCONFIRMED ESTIMATE (i.e. my math is a bit shaky here!) the crop-mode equivalent focal length on a Canon or Fujinon 18x B4-mount Servo Zoom lens put on the 5D mk4 SHOULD BE about 3700mm to 4000mm but my other conversion formulas also say it could be equivalent to 500 to 800 mm so I would like to see WHICH it really is!

I think MANY of us would LOOOOOOOVE to see DPreview do a REAL WORLD proof or disproof of my (i.e. unsubstantiated) claims!

Please Do It and Report Back on Your Results!

Thanks!
