Kim Letkeman: About as useful sounding as the ridiculous commercials that try to convince us that curved TVs "surround" the viewer ...

You'd have to be sitting about 6" from the set to feel surrounded.

Just examples of solutions looking for problems ...

I agree on TVs. My dad worked on early rear projection TV's for Sylvania (we had a large one at home way back in 1980!). When they left town, he brought home a competitor's (I think Panasonic) curved screen (front projected, like an outdoor movie). It was not good off-center - of course! But cameras ARE "in center" - the imager is the "audience". I really don't see how they get around the fact that different lenses would require different curvature. Maybe a curved sensor lessens the complexity of lenses, but it does not get rid of the issue of the lens and sensor curvature differing.

Good lenses are expensive and we own multiple lenses. So maybe overall it would be cheaper to have two (selectable) sensors in the camera, each having different curvature. More realistic - have one sensor in the camera, and put a sensor in the lenses which are at the extremes (either long or short lenses - I'm not sure which would make the most sense).

On Getting off the ground: Cheap drones for photography article (140 comments in total)
In reply to:

W5JCK: These drones are little more than a nuisance in residential areas. Plus the whole issue of privacy comes to mind. Way out in the countryside away from other people they are okay I guess, but not in our cities. I suspect that as the numbers of urban drones increases, so will the numbers of BB and pellet guns, at least I hope so. I don't even like photographers walking the streets taking my photo, much less a drone spying on me from above. I'm seeing and hearing a lot of opposition to even PD using these.

I don't blame you for feeling that way...and it would be illegal for the person to shoot such images as your fenced in back yard is literally the legal definition of a private area. It's 100x more realistic for some kid to climb a tree or simply look out his/her 2nd story window to take pictures over your fence though.

CNY_AP: Wow, it's depressing how short sighted people are, and scary how ignorant people are as I read these posts...and the posts are from supposed photographers who are scared of cameras!!! It's like when the wimps in Europe let Hitler take over other countries...nobody really cared until it was them who were at risk. Wait until it's YOUR hobby that gets restricted and see who is left to stand up for you!!!

Hardly are "drones" louder than a lawnmower or 100 other common things, or kids playing games, swimming in their pool (yelling hours on end). And it you can here the vehicle, then you know they are there, so hardly can they "spy" on you, which is illegal anyhow - we already have privacy laws on photography.

Even the paparazzi whackos haven't used multi-rotors. A SLR and telephoto lens is 10x better and more realistic. And what would you be doing in public that you wouldn't want photographed? If in public, by definition, people can see you, so what's the difference...that's the USA's laws' logic anyhow.

Keeping giving rights away, and before you know it, we'll have no hobbies left. What's the point in living with nothing fun to do - just to be alive is enough? Eating and watching TV is that much fun?

You cannot photograph someone who has an expectation of privacy, such as in their back yard. As for "spying" when a person is in public, hardly is a multi-rotor the way to do it - clearly none of you own a multi-rotor.

It would be VERY difficult to get a good picture, yet be far enough away for it to not be heard..simply physics and photography 101. In order to be far enough away to not be heard, it would need to be a telephoto lens. Any photographer knows the more you zoom in, the more the camera shake blurs the picture. I shoot pictures with no motor/prop spinning at all (I turn the airplane's motors of and glide), yet if I zoom in from the widest setting at all (still zoomed wider than 1:1), there is blurring at 1/500s shutter speeds.

Noise is annoying but privacy issues are ridiculous--do you get your shorts all twisted whenever you see a person with a camera? It's 100x easier to get a shot of someone standing on the ground with a good camera than shooting (usually blindly) from a vibrating "drone". And you can hear a quad-rotor, but you'd never know if someone takes your picture while they are standing on the ground using a telephoto lens. And I would hope anyone on this site has some common sense - you can't see through windows during the day, for one example.

CameraCarl: Every time I see a drone flying overhead, I wish I had done better in my antiaircraft marksmanship in the Army

Why's would they bother you??? Privacy concerns? A SLR with a good lens takes much better pictures from much further away.

On Getting off the ground: Cheap drones for photography article (140 comments in total)

Been doing it as a hobby since 1997 (with a Fuji F20 which works perfectly) using an electric powered RC airplane. Advantage of the airplane is that I

Can power off the motor and glide - no motor or prop vibrations. Disadvantage is I need a large spot to land, so I am putting together a large quad-rotor

BTW, "drone" (which implies automatically/autonomously guided) is not really correct term, and has a military connotation to it, adding that much more craziness to the ignorant public, so us hobbyists wish the term wasn't used.

In reply to:

Thematic: Some very bad advice in this video.

Like another member mentioned - do not use a cloth to clean the camera body and lens.

Most pros NEVER clean lenses with a reusable cloth anyway. Use a disposable lens tissue - you can buy boxes of Zeiss disposable cleaning tissues/wipes for very little money. That way you are not rubbing the same dirt you removed back onto the front lens element.

Not sure why Canon would show things like this in a corporate video unless it is a spoof or joke.

I dislike the idea of using a thin lens tissue. If there is "dirt" on the lens, how would a paper thin tissue keep the dirt from being rubbed all over the lens?
A micro-fiber cloth will however sort of absorb the dirt due to the lens pushing against the dirt - pushing the dirt into the cloth instead of on the surface (unless you press hard on the cloth, but the same is true of a lens tissue).
If your argument is why would there be dirt, then I counter that the cloth would never get dirty in the first place (ie: filled with harmful stuff) if the lens never has dirt on it.

Continuous AF in DSLRs isn't very good either unless they've greatly improved recently. I therefore use single shot AF for everything with my SLR.

On Sony Cyber-shot DSC-RX100 III First Impressions Review preview (2979 comments in total)
In reply to:

Boky: It is puzzling, really. I get more pleasing photos with my S90. The RX100 series is way too big to compete in size. I tried RX100 I and returned it immediately due to cold cast over all the photos it produced + not to mention the brick-like feel and size. If I go to an important event or holiday (or want to pixel peep) I take dslr and L glass with me in addition to S90. For P&S needs -> I have a camera that gives beautiful photo’s and I hardly know (or feel) it is with me. RX100 will have to shrink substantially to be able to compete with P&S cameras size-wise.
I did want to like RX100 III very much. But Sony needs to get the processing sorted and give us pleasing results that do not require couple off minutes processing per each photo to make them look nice. At the moment, to me at least, the RX100 is lost in space: way too big to compete with P&S segment, and with picture quality that is nowhere near dslr quality – yet it cost more than basic dslr and kit combos.

Doesn't it have a RAW mode? What serious photographer shoots JPEGS and/or expects to not edit images?

Rx100 is too expensive for my taste, but it's a fantastic camera.

On DPReview Gear of the Year: Canon Rebel SL1 / EOS 100D article (270 comments in total)
In reply to:

TN Args: This "Gear of the Year" rating comes from a man who says the Panasonic GX7 deserves a second-rate rating from dpreview.

Even more hilarious this rating, when you consider his only clear reason for picking this camera is that he already has multiple Canon lenses. That is such a personal factor that it is irrelevant to so many readers.

Let' compare the two cameras.

The "Not Worth a Gold Award" GX7 has:
- better sensor performance (check DXOMark or the dpreview widget)
- faster focusing
- more accurate and consistent focusing
- silent mode option
- bigger viewfinder
- better viewfinder information
- smaller body
- better looks
- many compact fast lenses
- better manual focusing, and focus peaking
- in-body image stabilization
- better videography 1080p x 60p, with videoactive viewfinder

Gee, that GX7 is obviously second-rate, Shawn.

Whereas the "Gear of the Year" 100D has:
- poor choice of compact lenses (lacks the very lens Shawn says he would most like)

WAY. TO. GO.

How many Canon lenses does the GX7 work with? A huge percentage of us DO have Canon glass.

When I read reviews and view the test images, the Canon 18mp sensors actually fare very well at all ISOs. I'm not convinced the few sites which rate sensors do it correctly/fairly. Any sensor can have ZERO noise if they simply average all of the pixels together into one value, for example. And how many people make huge prints? A 8x10 print will look the same from any decent camera (in terms of noise). Canon has not improved their SNR much if at all in a few years however, and clearly the knowledgeable users know this.

Too funny, it's not meant for "working" with - it's not a pro camera. Wouldn't it be horrid if all cameras were designed to work with gloves on - they'd all be huge!

On Canon announces EOS M2 in Japan article (619 comments in total)
In reply to:

Anastigmat: I am glad Canon uses the APS-C format for its mirrorless cameras. Pentax and Nikon are making huge mistakes using sensors smaller even than M4/3. Moving in the other direction is Sony, with its full frame mirrorless camera. In a few years, you will find that the only M4/3, and the Nikon and Pentax mirrorless cameras for sale are found inside glass cases in your local pawnshop.

Well, engineers look to the future and clearly sensors are getting higher and higher SNR over time. The M4/3 images are much cleaner than my old Canon Rebel 450/Xsi, which was the best sensor at the time (and the last time Canon had the lead - arg!).

While M4/3 (and all other sensor sizes) will get better and better over time, nothing will make a large camera small. Buying a full frame camera and lenses is already overkill for most people by far, and even more so as better full frame (and smaller) sensors are released.

The improvement in technology has allowed the size of the m4/3rds cameras (which were pretty poor at first) to become sufficient (they already beat Canon APC in my opinion). The 16MP sensor in the latest m4/3rds cameras are amazing - it's even Roger's favorite camera apparently. Or is he just an amateur?

On Panasonic DMC-GM1 preview (639 comments in total)

Olympus PEN is the main competitor...

And don't forget Sony has the BSI type sensor, so maybe the difference in IQ isn't as big as the delta in image sensors (and in good light, the difference would be very slight). I surmise the Sony would actually do better in low light than this camera with the slow kit lens, so you'd have to buy a fast lens to be comparable to the Sony (plus would need a zoom lens to match the Sony's zoom capability it has with its one lens)).
This new 16MP M4/3 sensor is excellent though by any standard.

The 4/3rds cameras are plenty good enough in every way now, but when I look at the lenses, none "wow me". Canon and Nikon for example have certain lenses that everyone loves, not sure if 4/3rds has any/many such lenses now. The 12mm prime lens seems like a very good lens, and is light enough to carry on my R/C airplane, but $800 is a lot of "dough".

On Preview:canon-eos-70d (1333 comments in total)
In reply to:

SaltLakeGuy: Across the board I see NO advantage of the 70D's output over my current OMD-EM5, in fact in most cases the OMD is crisper pulling better resolution. It's a nice try on Canon's part to improve upon the LiveView. Keep working on it I'd say.

Olympus current 16MP cameras are awesome...but they lack a mirror which many still like (I think I'd prefer an EVF). 70D just tries to catch up on live view / direct focusing, nobody claimed it had best in class IQ. But realistically, every camera that's in this new tool/scene looks very good, and in prints or display on a computer, they would be very hard to tell apart.

On Preview:ricoh-gr (295 comments in total)
In reply to:

Russell Dawkins: I am curious to know if there is a technical reason that image stabilization is incorporated into the design of neither the Ricoh GR nor the Nikon Coolpix A.

Because it's a fairly wide lens...telephotos NEED stabilization, but as you go wider, it is needed less and less (think about it). If you are taking pictures of people, they move, and stabilization won't make them stop moving. If you are taking pictures of landscape, why wouldn't you be using a tripod? That's the logic for ALL cameras / wide lenses.
