On article Sony a9 Full Review: Mirrorless Redefined (2754 comments in total)

Message to Sony:
I own the Sony a9 ( and the Nikon D5 and D810). It is outstanding.
Two things that bothers me a lot ( and I am sure that others too) are the dust collection of the sensor when changing lenses and unwillingly changing exposure compensation when rotating the rear dial (for selecting exposure speed as an example).

I would like to provide Sony with the following suggestions:
1. Preventing the dust collection by the sensor
Define a “lens change” mode in Setup.
When the user selects that mode, the mechanical shutter closes and protects the sensor from collecting dust.
Once the user exists that mode ift returns to normal.

2. Preventing unwillingly change of exposure compensation.
Define a setup mode that disables the exposure compensation by the dedicated dial. (I am using the Control wheel push down to set the exposure compensation.)

I did the portreture grading twice with a few hours in between and on two different Apple displays.
In the first session the scores were Nikon 32, Sony 24 and Canon 16. In the second session Nikon 37, Sony - 23, Canon - 14.
The results do reflect my feeling when looking at pictures I make with Sony and Nikon. I am a long Nikon D5 user and lately using the Sony A9 as well. I never used Canon. I always feel that the Nikon ones are more pleasent. That said, with the Sony I am able to shoot my granddaughter on a fast swing at 10/20fps from a close distance of 1 to 5 meters and get EVERY shoot fantastically sharp with focus on her eye. I was not able to same level of sharpness and definately not the focus on the eye with the Nikon D5.

One more important point: The Sony was able to acquire focus on the bird using Wide mode against the difficult background of high contrast dark see filled with many white spots of ice almost instantenously and with no axceptions. The Nikon, using automatic mode as well as group mode and 3D mode, was not able to acquire focus on the bird against such backround in most cases, and in the few it did, it took a long time. That is impressive.

I compared the Nokon D5 (with 300mm F4 FL) and the Sony A9 with FE 70-200 F4. I compared the AF of the two by shooting flying Kittiwakes on a ship from above with the sea and ice below as a background.
With the D5 I tried 153 points as well as 3D. The sony was put on Wide.
With the Sony AF , I was able able to acquire focus and follow the fast manouvering bird with 100% hit rate. Also, if the bird left the finder and returned it acquired focus almost instantly and stayed with it. With the Nikon, as long as the bird stayed in the 40% of the frame focus zone it did as well. Once the bird got out of the AF zone, it instantly focused on the background with no recovery. If the bird got completely out of the frame and then back, it almost never re-acquired focus on the bird.

On article What difference does it make? Sony uncompressed Raw (622 comments in total)

The reason Sony has not offered a non compressed raw is that they have not yet resolved the weakest point (followed by terrible menu, weak battery) of this amazing camera - memory read and write. It takes 2 to 3 seconds to write a raw file of one picture or to magnify a picture. Now imagine the 4 to 6 seconds it will take to read/write a non compressed raw file that is twice as bug! It is a killer!

In reply to:

PerL: This is a lens for pros that wants the special look it provides, for the same reason Canon photographers gets the very expensive 50 1.2. Of course it seems overpriced for lot of people, but they are not the market for these kind of lenses.

That is correct, but even pros will struggle with the focus issue.

On article Nikon AF-S Nikkor 58mm f/1.4G review (416 comments in total)

I am using this lens with D800 and D4. I got so many pictures out of focus that I thought that something is wrong with my lens. I placed a question in the DPR forum about it.
In this excellent review I got the answer.
When the focus is OK, the pictures are just beautiful thanks to attractive background blur.
Is it worth the 4x the price of the 50mm 1.4 lens? Absolutely not!!
If Nikon can do something in software to correct for the focus issue, then maybe.

On article Best Camera of 2012: And the Winner is... (1413 comments in total)

I followed the accumulating voting results on a daily basis.
Based on the way it developed, i strongly suggest DPR checking how a specific camera got the first place.

On article First Impressions: Using the Nikon D800 (307 comments in total)

Hi Barney,
Thanks for the review.
I have received my camera and based on one wedding event, the camera is outstanding.
I have found two issues that I would like you to look at:
1. The memory buffer for burst shooting. I find it impossible to be above 13. I set the maximum to anything between 13 and 100 and it shows always r13. IF I set the max below 13, then the actaul follows.
2. Clean image sensor in the setup menu. No matter what you set and press OK, it shows "--" as if it has been set to Cleaning off.
