JackM: Please look around the entire test image before commenting. It's not all roses.

And please remember that the K1 will be used WITHOUT PIXEL SHIFT 95% of the time. The terrible results without pixel shift are a dealbreaker, if this test shot is to be believed.

I have noticed that too, but it is probably lens issue. Seems to be softer farther from the center of image.

On article CP+ 2016: Hands-on with new Sigma SD cameras and lenses (308 comments in total)

Kudos to Sigma, they are doing very well. Very nice addons to their lens lineup. New cams look definitely good too. I can understand why they choose to use SA mount instead of creating new one for MIILC, it just doesn't make sense for them at this moment. Foveon is still not for everyone, this won't sell like hotcakes, so it won't be profitable to do that. These cameras looks to me more like successor of SD1, than new MILC.
Anyway I wish them greater success with foveon and hope that other players will catch this train in near future too. But personally, I would rather see cams with full color sensors, like merril, not quattro.

povetron: I am quite curious if the A-7II and other upcoming Sony's system cameras will be affected with limited bit depth of raw files, like A7/A7r.

@ marc petzold

You are right that it is nothing new, but I still think that it got importance. From the body like this (ff) I expect IQ not to be crippled with the thinks like this.

VREN: This is the most definitive comparison that I have seen so far on these "large" sensor "compact" rivals. I assume that these shots were taken at the optimum aperture for each camera (where the lens performs the best). From my point of view, the lx100 performs the best of the three in RAW, even at the lowest ISO level where I thought the higher Mpix rivals might shine. It seems to have the best clarity, good corner performance and maybe even sharper despite lower pixel count. I had my doubts about the lens performance, given its size, but after seeing these I believe Panasonic is worth the extra money as it is the most capable in feature set, ergonomics, and image quality. I also don't like huge raw files and this is another plus of the Lx100.

Thanks for reply about lens sharpness, I realized that a bit later that studio comparison shows only iq with optimal focal lenght and aperture, with flat scene. You right it's more about iso and color rendition.
I have seen exif with this kind of information when opened full size image, for example here(using Firefox plugin FxIF):

I fully agree with you. But this is quite in contrary to the image samples we have seen here before, they seems to be worse. Image samples from photographyblog.com looks better.
Dpr, why even the samples of ooc jpeg got in exif this info: Software: Adobe Photoshop Camera Raw 8.6 (Macintosh) ?

Buzz Lightyear: My first thought: this colored mess must be murder on the environment! I can find nothing on their webpage to explain how toxic (or not) the substance is that they use in the photos. I hope I am wrong about this . . . but it seems rather callous and careless of them if the environment is in any way being ruined by their efforts to promote their "art".

ThatCamFan, you are right that it will leave the mess. The question is how long does it take to dissapear (rain, etc.).

They use some kind of non toxic water based color. They mention that under the third picture.

That is what I was waiting for. Kudos to Sony.

In reply to:

povetron: Hey, this is an pretty nice lens.
But I would like to see more pancake lenses to acomplish compact mirorless bodies. They could be slower, but should be optically and mechanically flawless and really compact. And then I will be in. M43 got too small sensor for me.

I ment that there could be an option of having really compact pancake lenses eg 24,35,40,50mm. Because main adevantage of mirrorless over dslrs should be in compact size. And zoom lenses and large aperture lenses doesnt accomplish that. Just to have combo of large sensor camera with lenses which fit into the pocket.
But you right, I am too choosy, there are already some good solutions.

Great litlle camera, would like to have one.
But it would be nice if there could be also a version with eq of 35mm lens.

On article Equinox modular and Leica X3 concept cameras (41 comments in total)

The Leica X3 concept looks very appealing, but can't imagine how to put all necessary things into that and make it functional. Especially if bigger sensor would be used.
Maybe I'm wrong, don't know.

In reply to:

_sem_: So, this PDAF will have issues on red and blue objects, hehe
Why are the PDAF pixels not white?

If it is white, than that's cause the pixel without color filter can perceive much more light. This could be helpful in low light.

I really like the way of Fuji X-Pro1 and Oly OM-D, so my ideal camera could be quite similar to this:

+ aps-c sensor with Foveon or X-Trans CMOS sensor with adequate resolution (max 16MP for aps-c), no AA filter
+ same controls like on X-Pro1, rather smaller body
+ in body stabilization
+ base ISO 50 (with best IQ)
+1/4000s shutter, quiet shutter
+ hybrid viewfinder, with focus peaking in OVF, accurate digitaly projected framelines for composition with paralax correction in OVF
+ external phase detection AF sensor - like in Ricoh GR Digital IV, good AF performance in lowlight
+ at least 400 pictures per battery
+ two sd card slots
+weather sealed
+ 24,35,50,80,135mm fast primes, 24-80 f/4 zoom,35mm pancake prime, FF EQ, distance and DOF scales for manual focus - like Olympus M.Zuiko 12mm f/2 ED, apperture ring with 1/2 stops clicks, displayed values + A position,
weather sealed
+small flash unit with ver bouncing, built-in bounce card, highspeed sync

Geo in Nv: Great to see the expansion to Books. Kertesz 's work is among the finest ever recorded. I realize that's my opinion, but his work just sings.

agree with you. Doesn't matter only what camera you use, but also how can you use it and what's your results. Sometimes I spent too much time reading about gear and forget about this. Hope there will be more articles about photography and not only about hw&sw.

Link | Posted on Sep 27, 2011 at 20:00 UTC

Looks like a good compact camera. Bigger sensor than enthusiastic compacts, smaller lenses than on m43 and aps-c. 10 MP sensor is an enough for the sensor of this size. The built in viewfinder also a advantage. But little bit overpriced for the camera of this sensor size.
Hope there will be some equivalent of fast prime standard lens. Anyway, I m looking for the review.
