On article CES 2017: Hands-on with the Kodak Super 8 (426 comments in total)
In reply to:

Polytropia: To all the haters:

My grandfather shot Kodachrome Super 8 & also black and white movies of his kids. Those movies look as good today as they did when they were shot.

How good will all your digital videos look in 65 years from now? Will they even exist?

I can shoot some film and put it in an archival box with a projector, and know it will be viewable in 100 years as long as there is a source of electricity. I'm not sure you can say the same thing about any digital information formats.

And honestly how much more often do you really want to watch such videos? lol.

Also, protip: clouds evaporate.

Actually, regarding super 8 - the quality was really lousy (probably <300 line resolution). My dad shot our home movies in 16mm Kodachrome. These are still in good shape. Had them transferred to Video Cassette (which degraded the quality). Need to have them scanned again to a digital file.

Have no Idea why Kodak (if this is really Kodak of Rochester and not China) would be wasting whatever resources they still have on such an product.

Mark Turney: Well, we live in an analog universe so it's no wonder to me why digital tends to "feel" wrong. But I'm also not sure that going back to a old technology is the answer, especially considering that Kodak digitizes the film from what I understand, looping us right back to that which we seek to avoid.

Anyway .... just some food for thought 💭

Actually, film is really digital. It essentially counts photons - which are intrinsically digital. A photon hits a silver grain, and if absorbed ( which is a probability), the grain is reduced to silver during development. Grains are either silver (1) or not silver (0) after development (fixing removes the non-reduced grains).

Albert Rose's book, Vision: Human and Electronic, has an interesting discussion on his subject.

No 24mm and no EVF - deal breaker for me. At least they fixed the slow Raw speed.

I have the Loka. The concept is pretty good, though execution so-so. In particular the ICU fit into the pack and its attachment method leave something to be desired, and the internal dividers design don't provide optimal fit for my camera and lens configuration. I have used it on long trips, like the Annapurna circuit, for the ability to carry extra clothing, food, and water. For local photo outings, I prefer the Lowe flipside packs.

The biggest issue is the company itself. It appear to be run by totally inept people. They seem to have no control of inventory or delivery schedules. You might want to order a particular pack, only to find that the ICU size you want is not available. Packs that are not in stock might require a wait of many months.

A company with great gear and lousy service does not deserve to be in the "gear of the year". Not sure what DPR editorial staff was thinking in this case.

newworld666: Who needs to underexpose more than 2Ev ? for a while those comparison at -5EV or -6EV are just ridiculous and useless ..
The king of such feature is unable to keep correct colours at any iso level ...

who cares to use -4, -5, -6 EV pictures with totally wrong colours ?

Nikon managed to make 25600 as good as possible

and better than 1Dx

This just mean in 8bits JPG files you can get 8EV full dynamic at 25600 iso which sounds just amazing never reach before with true colours.. much more important than the ridiculous -5EV at iso 100 ..

It is not underexposure that is the object of this high dynamic range, but rather the ability to lift the shadows that landscape shooters are looking for. That said, typically, you don't typically need to use more than+3 ev to do that. Occasionally, when shooting s silhouette against a bright sky you might need considerably more.

Link | Posted on Mar 29, 2016 at 16:28 UTC

The high ISO improvement over the D750 is less than 1/2 ev at most - which is negligible. Any ISO over 50K is useless - except maybe for surveillance purposes (or abstract art, perhaps). Does not appear that they have changed the Bayer CFA or gone to BSI - which are about only areas to improve sensitivity.

This also does not bode well for a significant improvement in the D500 sensor at high ISO. We are in the era of photon limited sensors.

On article Taking it easy: Canon EOS 80D shooting experience (292 comments in total)

Strange - what were they thinking?

Seems like there is no cohesive design approach in the video area.

Here they add the dual pixel on chip PDAF that should be great for video. Then they leave out the "... several video making tools that seem to be par for the course when it comes to other manufacturers, are absent in the 80D, specifically: Focus peaking, zebra stripes and a clean-HDMI out option. There is also no C-Log gamma option (a very flat tone curve useful for color grading)."

And no 4K.

Guess they don't want to impact the sales of their dedicated video cams.

piratejabez: Decent detail, acceptable noise for such a small sensor, but RAW doesn't appear to be able to add any useful benefit apart from exposure (and ACR doesn't know what to do with the colors). I think it's a great option for casual or traveling JPEG shooters.

Also, totally wrong to say that small sensors benefit more from RAW than large ones. The DR is so low in the 1/2.3" sensors, that the ability to lift shadows is minimal, as is highlight recovery.

I would not agree it is acceptable. Especially at full zoom , quite bad. Agree the raw can not perform miracles, though it does allow one to easily adjust color balance and optimize nr to some degree.

In reply to:

FBoneOne: I think the technical term here is "holly crap" - the wildlife shooter's wet dream comes true (unless you can afford the D5 ). I can see this puppy and a 200/500 as the "does 99% right" combo for wildlife. I will give it 9 months to let the usual Nikon QA issues resolve themselves and next Christmas I am all in :-)

The D7200 may better for wildlife as it does have more pixels, giving greater reach. We will have to see how the D500 sensor compares with respect to noise. D7200 is roughly half the cost, so FF shooters who need the crop factor for their telephotos might prefer it.

Hopefully for PDAF - if they add this to the sensor chip.

On article Inching forward? Canon PowerShot G5 X review posted (402 comments in total)
In reply to:

haiiyaa: Seems like a great camera that's really fun to shoot with which is the most important thing. The constant menu diving with the rx100's really isn't a enjoyable experience. The Panasonic lx100 is better in that aspect, and I having used the canon m3 for a couple of days I have no doubts the canon g5x is much better at that also. That said, 1.2 raw fps is very poor and so is the battery life.

I agree with Rishi that the issue with Sony should improve onthe user interface is " (1) adding a 'My Menu' and (2) by allowing more features to be assigned to Fn menus and buttons, and (3) actually organized menus." Even so, I prefer the Sony interface allowing greater control than the Canon.

I disagree that Sony menus are worse than Canon - at least on non - DSL cameras. Have not tried the G5X but have the G3X, as well as an RX100M3.
Canon is frustrating on the things they leave out and the lack of customization. Sony almost has TOO many options: their problem is more of having an almost random ordering of items. Function Assignment on the Canon is much more limited than the Custom Key settings on the Sony. The function menu on the Sony can be changed - can't do that on the Canon.

Another thing missing from the Canons is Zebra - very useful for setting exposure to avoid highlight clipping.

On article 4K video: What you need to know (286 comments in total)
In reply to:

Att Slangas: I miss some aspects of current 4K limitations in this article:

1. Limited Framerate: I always shoot 1080@60fps. I have trouble shooting hand held in 30 fps or lower without getting unbearably strobing videos. To get smooth output in low framerate (30fps or lower) you need to pan around very very slowly and keep the exposure time at around1/60s. In 60fps I don't get particularly annoyed even if I shoot at 1/1000s. Which leads to:

2. You need to decide, when shooting video to extract stills, if you want to use the output as stills (then use fast shutter times and get stroby video) or as video (1/60 or 1/50 s)

3. What is the dynamic range of the 4K output? What are the compression artifacts in a 4K video.

Would be interesting to see some side by side comparisons of these aspects.

Agree... 4K/30fps is definitely choppy for fast motion, though improved if you use slower shutter (1/60). Also, the combination of higher def and low frame rate make hand-held shooting difficult for still scenes (you get a jiggley image), even with lens stabilization. A tripod works a lot better.

The studio comparison looks a bit out of focus in the center. The RX10 sample looks better than the RX10m2.

It appears that the A7RII has slightly lower noise than the D810 in RAW at high ISO. OTOH, at low ISO, the D810 looks a bit sharper than the Sony.

Link | Posted on Sep 2, 2015 at 19:45 UTC as 14th comment | 5 replies

As is pointed out in the article, the stage 2 compression (a run length encoding process) is the one to create artifacts near high contrast edges. This is the part the worries me the most - it might well interact with USM and cause issues similar to Jpeg near edges (i.e. "mosquitos").

I think Sony sticks to compression mostly out of stubbornness and the need to save face. There is no excuse NOT to give the user the option of uncompressed RAW on any camera that offers RAW. Other than larger file sizes (and maybe slower writing). Let the user decide what they prefer. Sony could still offer compression as an option, like Nikon.

As to Sony not doing firmware updates, they do sometimes (like the improved CODEC in the RX10m1). Certainly anyone with A7xxx should complain to Sonny support asking for them to do an update.

I believe that DPR, by escalating attention to the issue, has done us a service and perhaps will get Sony to act.
