where do you find these prices? 6d is 1600 euro, d610 is 1400 euro. A7R is just stock clearance.

what i actually wrote did not actually show. so I'll take it again. I have shot with both the Sony a7r and Pentax k1. And from my experience the Pentax produce s much better result than the Sony. ...

having shot alot with both the A7R and the K-1 I can say from my own experience that the k-1 is way ahead of the Sony. Sony looks mudled with allot of color noise where Pentax has details. Butoa wrote:

because we fint have hard evidence that they have tested any other 50mp mf sensor. We do with pentax 645z.

Living in north of sweden I can say that I have less sucsess with the astrotracer when im up here than I have when im traveling to the south of sweden. I dont know if Pentax k-1 also implements ...

I had the oposite problem. my voigtlander 180 could not get correct infinity focus on my k-5. On my k-1 ot works perfectly

Why does it work for me. Are you following these steps? http://www.dpreview.com/forums/post/58046108

then something is defenetly wrong with your camera if af-c dosnt work if followed these steps http://www.dpreview.com/forums/post/58046108 I tried mine in manual mode and worked like a charm

Sure it tracks, but non of the weaving shots are tack sharp on the face. Soft lens is ruled out sence the Z axis tracking produces sharper results. Maby it decides to track somewhere more in the ...

RX10iii has an 1" inch sensor that you used at 100mm f4.0
Thats exuivalent to 300 mm but the depth of field is quite large at f4.0 with a 2.7 crop.
If the camera didnt nail focus there I would be...

how can you defend a test that you constantly change what was in focus, first jersey, then lining between jersey and pants when it came to light that no focus point covers the jersey. Then when...

i find it funny that rishi just ignored this post

And stressing a focus point not intended for f2.8

In the first test, the one where the image comes from. They chose the topmost focus point and tracked that focus point all the way. That focus point is not f2.8.

Instead of justifying all the errors in your test. Why not focus on how to make a test that acually works and that is repetable?
My guess would be that the energy it would take would be much less....

rashi sanyal: So you are using a non f/2.8 focus point to test focus with a lens at f/2.8?
Things starts to get better and better

your test is not a "controlled test" A controlled test would be uniform speed and have focus Points locked on the same area where focus is easy to evaluate.

very responsive, and so very full of pride that they can't admit the flaws in their testing.

sorry, if you can't produce 15 shots in a serie at f/2.8 and 200 mm at the same distance. Having your camera on a tripod focusing on general groin area, and getting sharp faces. Your test is a dud.

lets get brainstorming, what is a better test than a biker that has focus points all over the place. Jersey, groin, handlebars etc. find a travelator (the flat escalators you find in airports and ...
