Czyżb AF w bezlusterkowcach rzeczywiście stał się już szybszy niż w lustrzankach profi?

„These are my results:

E-P3 E-P2 E-P3 is faster by
1) 0,82s 1,41s 42%
2) 0,89s 1,46s 39%
3) 1,96s 2,26s 13%
4) 0,87s 1,54s 44%

I have no way to know how long it took to aim the camera between each shot but it was not much. Just turned the camera a few degrees up or down. Olympus gives a shutter response time of ONLY 60ms for E-P3. My conclusion is that E-P3 is in practise twice as responsive camera as E-P2. With older 4/3 system DSLR lenses the lens is the restricting factor. I would guess that these lenses would benefit of a new firmware for m4/3 bodies.

So how responsive E-P3 is then? Olympus claims it to be the fastest focusing camera of all system cameras. Lets see!
I repeated the same test with Nikon D3x and three Nikon lenses:

5) AF-S Micro Nikkor 105mm 1:2.8 G
6) AF Nikkor 85mm 1:1.4 D
7) AF-S Nikkor 14-24mm 1:2.8 G. Tested at 24mm focal length.

Results:

D3x
5) 0,97s
6)1,15s
7)0,70s

Results for differences between these three lenses are logical and should be familiar to everyone who has used them. Wide angle zoom 14-24mm is fast because there the distance to move focusing element is so short. Other than that look at E-P3! E-P3 is faster (with three consumer grade lenses) than Nikon. It´s responsiveness is up (or should I say down) there with a super fast professional DSLR with 10 fold price tag! ”
