On Nikon D810 Preview preview (1219 comments in total)

High ISO noise is better than D800 and better than A7r starting from ISO400.

Excellent. Superb images on his site too.
#2 is breathtaking.

JEROME NOLAS: Overall excellent creative approach to photography! From #1 to #7 flawless, #9 and #10 OK.

I actually liked #10 a lot. :)

Sirandar: At last a successor to the FZ30/50

It has no where near as good high ISO performance as an OMD E5 ....

But to never have to change lenses again ...... what a dream

OMD E5 has a larger sensor, its ISO would better.

snegron2: Beautiful design, great lens, but like the FZ-50 (which I still own) the details look smeared. In the studio comparison section check out the green blades of grass (or feathers?). The smeared details at ISO 400 are very similar to what my old FZ50 would produce. As I mentioned here when I wrote about my FZ50, I wish I had the technical expertise to swap out the FZ50's sensor with that of a better performing sensor. Even my old LX3 could out-resolve my FZ-50. This time around I think I can get equal or better results from my mirrorless G5.

I think up to ISO3200 FZ1000 will do pretty well. One will just have to shoot RAW and process. Two ISO3200 examples:

And also, it is not fair to compare with OMD E-M5 because one was taken with a superzoom lens and the other probably with a prime. But I agree, JPEG isn't very good.

jackpro: Was super interested after seeing comparison with G1X but colour is blah sorry but canon nails colour with no tweaking necessary :( wanting a new travel camera will keep looking)

DR Optimizer has no effect on RAW files.

Optically (at this focal length) version 2 appears to be sharper at the center up to about 1/3rd of the frame, after this version 3 is significantly better. Noise wise, version 2 seems significantly better (less and finer noise), this is evident even at ISO200 RAW samples.

On Canon announces 16-35mm F4L and 10-18mm F4.5-5.6 lenses article (367 comments in total)

The Digital-Picture.com has published MTF of the new 16-35/f4. You can also compare it with 16-35/f2.8II and 17-40/f4. Scroll down and click of respective lenses.

http://www.the-digital-picture.com/Reviews/Canon-EF-16-35mm-f-4-L-IS-USM-Lens.aspx

It seems that the new 16-35 is significantly better than both 16-35/2.8 and 17-40/4.

Canon 6, Nikon 3, iPhone 2. These are among 60 of course.
Excellent images. Some are really stunning.

Joy of taking pictures with a mirrorless redefined. If the lenses are top of Leica quality then I am in. :)

In reply to:

aftab: In a recent interview Sigma president commented that they could have made this lens a little more sharper, but if they did then they would have sacrificed some local contrast, so this is the balance they went for. So, the trade off between resolution and contrast continues in designing lenses. It has been said that historically Leica favored contrast slightly over resolution and Zeiss did the opposite. Leica surely were able to create more ardent fans with their approach than Zeiss did. In an interview Leica's top engineer said that although now lens designing is much easier with computer input compared to before, subjective human input of their designers continues as before. While this kind of tests or MTF surely gives us a good insight as to how the pictures from a lens would look like, real life pictures definitely would give us a more complete picture. After all it is not all about sharpness, CA, vignetting or distortion. Hopefully, DPR would show us some real life comparison.

@Kendall, it would be nice to see some comparison 'real life' pics from different lenses including Sigma and Zeiss.

In reply to:

rccasgar: Jeff,

Without considering cost and size, which camera would you choose? Canon G1X, Canon G1X Mk2 or Sony RX10? Why?

I did look at DXO and then looked at comparison pics in IR. All I saw was 2/3rd of the RX100II image was soft. Then I downloaded RAW files and processed them. I will pass DXO on this one.

In reply to:

Boky: I had a good look at the samples photos. They seem too "blend" with compressed dynamic range, quite lifeless, over-sharpened but with no sense of depth at all... something I'd expect to get from the likes of S90 / S95 / S120... very disappointing.

Nick

Download some RAW files from Imaging Resource (I don't know if any other sites have them) and process yourself. I have tried up to ISO3200 (although I hardly go above ISO1600) and I am impressed.

steve ohlhaber: If this shot 60fps at 1080p, I would be more interested as a solid backup to an SLR for still and video. Sony does it on many models.

It would be nice to see a 1inch sensor that has a better zoom range. I would love a camera that can cover 24-300mm AND shoot raw with a big sensor and pocketable. That should easily be doable given a 1 inch sensor is much smaller than this camera. Its like it forces you into a narrow zoom range AND no movie mode. So if you need tele or video, you need 1 or 2 other cameras. That just makes no sense to me. It seems hard to own this as your only camera due to those missing features. My father just got back from a trip around the world with the rx100 and his big complaint was predictable, not enough zoom range on either end. I think 24mm is enough on the wide side, but 120mm just isn't much for long zoom.

Then 300mm won't be enough for many. At the moment bridge cameras like FZ200 is the only answer what you father needed as far as zoom range goes. Look at RX10, it goes up to 200mm and it is not small.
