This weekend I tested E-M1 M2 and also m4/3 300/F4.
When used in S-AF the E-M1 coupled with the 300/2.8 and the metabones + Canon 400/5.6 produced encouraging results. Fewer frames suffering from OOF compared with the E-M1. Still not 100% reliable, but OK.
The 300/4 was spot on when used in AF-S. So gave the setup a good workout in C-AF. However, having read all the praise of the improved AF system I must say I was really disappointed with the C-AF performance. Out of some 500 frames and after review in the computer I came to conclusion that I got zero (sic) keepers, all frames OOF.
Focus acquisition was fast, only at few occasions the setup would hesitate or fail. However quick review in field showed that something was wrong.
I tried the following settings:
AF points: All, central 9, central 5, even single AF.
C-AF, C-AF + tracking.
IS-1, IS off.
Finally, in desperation, I tested a static subject. S-AF locked as expected, whereas using C-AF/C-AF+Tr on same subject resulted in OOF result.
Attached:
The Tern: this is the best shot of 500+. At a first glance it looks semi-OK but closer inspection reveals it shows quite pronounced OOF.
The tulip is shot with single AF point, positioned so that it aims at the central tip of the central leaf
Shutter release prio OFF.
Camera locked focus immediately, no hesitation.
1/250s, F/4
The first is S-AF. More or less spot on.
The second is with C-AF. Notice the severe OOF (front).
Anyone else?
