Yake: I paid of a few of the plugins a long time ago and have gotten a lot of use out of them. The only sad part about seeing them free is that this suggests there will be no further development of these products.

Hard to say, Free Apps generally make a lot more money than the paid Apps, you get a lot more users so you have to make money through advertising or something else. They could just be doing it to increase market share.

Matsu: Shorter flanges have no advantage for modern autofocus designs, which are highly retrofocal for reasons other than clearing the mirror-box. Every full frame mirrorless lens is just as big as it's DSLR counterpart at the same aperture and focal length.

What these new Sigmas show us is the smarter way forward for Canon and Nikon, and Pentax, if and when they choose to offer a mirrorless model.

Helping third parties mount glass on your cameras doesn't help you sell more glass and orphaning existing users doesn't help you sell more cameras.

By keeping their existing mounts intact they can offer both EVF and OVF based cameras that make full use of their catalogue of lenses (past and present).

More specifically, Sony neutered their E mount system with a narrow opening as it was always meant for APS-C. This prevents large rear element lenses that offer good performance which sit very close to the sensor. For true telecentric designs, the rear element has to be larger than the sensor, but even one with a large rear element can perform well. The E mount doesn't allow this for full frame, so you end up with retrofocus lenses anyway. This is uniquely a Sony issue, not close flange distance in general, as the RX1 has a lens basically touching the sensor and has great corner performance and a small lens.

VadymA: Looks like Sigma did their marketing research and determined that their camera users are predominantly right-eye photographers with either exceptionally small hands or missing pinky finger on the right hand
:)

Again, look at the size of the grip, it is very large. http://camerasize.com/compare/#669,478
Also, if you are like me the pinky finger is usually resting under the grip on any grip that is on the small side. There is also an available battery grip that would let it fit a pro basketball players hands.

Mssimo: Did they upgrade the battery size?

Well, I see an optional battery grip, does that count?

Link | Posted on Feb 23, 2016 at 19:48 UTC

The grip is not that small, go compare it on camera size or similar and will see that it has a fairly large grip, the camera is big. Also, a persons pinky finger could probably rest under the grip comfortably as well. Doesn't look bad to me, about the same as my NX1 which has a perfect sized grip.

Chris Joy: APS-H, a great looking add-on grip and those wonderful Foveon images - to bad about the super short standard grip, the wonky EVF placement and no video.

It could have been a contender....

No video is likely due to some hardware or processing power requirements, maybe eventually, but I doubt it is something that can be fixed except on a new generation of camera/sensor. There are plenty of people looking for still cameras though, and this is an interesting mirrorless model.

Bob A L: Is sigma lying about the f1.8 - article says it performs like a f2.8 - one whole stop off?

I didn't read the article yet, but people get really confused on equivalences. You can't accurately describe the lens as a 75-150mm full frame equivalent, without saying it is f/2.8 equivalent. The lens is not a 75 to 150mm lens (we know that) and it is not f/2.8. It is equivalent to using a 75-150mm f/2.8 lens on full frame, but it is still a 50-100mm f/1.8. If you shot a full frame image at 75mm f/2.8 ISO 250 1/100 you would shoot an APS-C image at 50mm f/1.8 ISO 100 1/100 at the same MP resolution and they would look near identical. Try it sometime. They would have the same image noise, the same motion blur, the same depth of field, and the same framing. Nothing would distinguish these images (not looking at MTF right now). The benefit to full frame is it allows added flexibility, shoot at same ISO for higher image quality but longer shutter speed, or higher ISO for fast shutter speed and shallower depth of field.

In reply to:

Debankur Mukherjee: With these types of lenses the need for full frame bodies will diminish.........

Full frame has never been unilaterally "Better". A different way to think about it is that full frame is more flexible. You can extend your shutter speed to get a cleaner image, or trade shallower depth of field for faster shutter speed. etc. It is still a set of tradeoffs, you have to give something up to get something.

On article Special K? Pentax K-1 First Impressions Review (981 comments in total)
In reply to:

Aroart: Not to be a downer looks like a great camera at a bargain, But why would Pentax introduce a brand new full frame line and make new lenses when Mirrorless in on the rise and dslr's will prob be out the door in a few yrs.. Just a thought ... They should have teamed up with Samsung, made a mirrorless full frame, Pentax lens friendly with a speed booster to get the full frame and have a camera of the future...

Samsung had other issues with their name and marketing, I hope their tech stays around as they had the best sensor in the NX1 of pretty much any camera (or tied with the best, but given faster frame rates and other features it was better). If they applied that tech to a full frame sensor it could be amazing.

I imagine Samsung will continue making chips related to cameras, or at least I hope so. They really leaped frogged to the front of the market in terms of performance, and no one really noticed before they seemed to have gotten the axe (at least we have no official confirmation).

On article Special K? Pentax K-1 First Impressions Review (981 comments in total)
In reply to:

Jorge Bayonas: It makes a lot of sense that Ricoh is pricing the Pentax K-1 low enough. There is no cutting edge (or jaw dropping) technology in it and the majority of customers are buying Nikon, Canon, Sony, Fuji and Olympus gear. So what is left to Ricoh? Market it at a low price is the only option - if Pentax would get the same interest as Canon or Nikon from all the consumers and professionals - believe me - the pricing of their bodies would be the same as Canon or Nikon.

Unfortunately, Canon and Nikon are losing sales to Sony left and right, and I have seen some pretty good deals on Canon Full frame, I think they had one around Christmas on the 6d for around $1300 with a free printer.

On article Western Digital announces plan to acquire SanDisk (70 comments in total)
In reply to:

gonzalu: Oh boy! I used to like Sandisk, until they get acquired by WD, then I will have to find another brand. So sad. Why can't these people leave well enough alone?

Or looking at it positively, Sandisk may inject reliability into WD as a whole?

WD is no worse than any other spinning disk company, and the entire reliability issue is the spinning disk part. I imagine nothing will change with SD other than where the money goes. If anything they could use the memory from SD to make WD SSD drives, so probably nothing changes in terms of SD.

On article Western Digital announces plan to acquire SanDisk (70 comments in total)

Smart move on WDs part, my feeling is spinning disk is on the way out. Especially for anything consumer oriented like portable hard drives. An SSD is a fraction the size as a portable HDD, but more importantly they are 3 or 4 times as fast for both reads and writes and much less likely to suffer damage if they are dropped. What does Seagate have up their sleeve? Hopefully something...

On article Samsung introduces PM1633a, world's first 2.5" 16TB SSD (121 comments in total)
In reply to:

dwill23: I read some comments and the same ol and ol comes up again and again. "Too much capacity is too risky to use". I call HOGWASH on that.

When I sold 32MB (yes mega byte) CF cards for $100 at Ritz camera NO ONE DARED to buy the 64MB cards and the 96MB cards for the exact same fear. "I might lose everything if the card fails".

Now a days we have photographers not wanting 128GB when they USED to be scared to dead of 64GB. This is an endless silliness that I'm so sick of.

I wouldn't trust one of anything, you get 2 or more and make a nice RAID. The fact that it is 16 TB or 16 GB is irrelevant, the problem still stands.

On article LG G4 camera review (107 comments in total)
In reply to:

M4ENY: Lars Rehm thank you for a detailed review of the G4 camera...
My question is which mobile camera do you prefer after testing out the different flagship devices?

I am deciding between the S6 and G4 and would love your input regarding their cameras :)

I have an S6 Edge, my Wife an G4. I prefer the S6 as it doesn't clip highlights as easy in default shooting mode (what I use 90% of the time). Lars has done far more analysis though, this is just my casual observation when I use them for a quick snap. I am a sucker for quality, so the S6 is my preference as overall quality feels better on the phone, for G4 benefits are removable battery and memory.

On article #1 in France: Hands-on with DxO ONE (278 comments in total)

Neat camera, but interesting choice of lenses. The iPhone already has a pretty good fixed focal lens of similar field of view. It seems to me a zoom lens would add more to the system, something like this and I would be inclined to use a Ricoh GRII or something instead. Especially since they made this only work with less than half the smartphones.

Joe Ogiba: My 6.44" Sony Xperia Z Ultra smartphone with 20mp APS-C QX1 takes any of my E /FE mount lenses or any APS-C/full frame lens on the planet using low cost adapters.

The only real use I see for QX series cameras is odd mounting, the one I tried was much too sluggish and annoying to use as a normal camera. Difficult to compose at a choppy 1 to 15 fps when a good camera display can do 240 fps refresh. Radio interference would sometimes block it from working at all, etc.

Ulfric M Douglas: How will you know you want "4K Photo mode" instead of Video and instead of 16mpx Bursts?
What narrow range of uses would it be best for?
How willll yoooo knooooow??

It is great when you need to get a shot of a presenter or something, shoot 4k video of the presentation and you have basically full size stills of anything you want. I say presentations because too often you just miss a great shot and instead catch a person giving what looks like an O face or something.

In reply to:

ptox: What's the downside to the electronic shutter? -- I assume there is one, or why would they bother with a mechanical shutter as well?

I haven't looked at specs too closely yet, but most electronic shutters on CMOS are rolling electronic shutters where it might take 1/30 of a second to read out the sensor. This causes a problem for flash sync, flickering lights, or moving subjects. I.e., never use this feature if you don't have to. I don't know if any CMOS sensors are capable of global electronic shutters yet, once they are your mechanical shutter will probably go away.

Edit: They mention electronic first curtain shutter, that has no side effects of note (rare, some shadowing with large aperture lenses at high shutter speeds), but eliminates almost all shutter vibrations in the image.

Battersea: Would make an ideal travel camera. Again I'm glad that Sony is pushing innovations. Hopefully Canon starts to take notice.

Many of us were reporting that SLR days were numbered many years ago. Canon (and others) kept stating their SLR business (and other premium compacts like this one) were sound. That is when Canon needed to take notice, it is much too late now.
