Hey everyone, since selling my Canon gear to move to m43 I've been shooting with just one top quality body (I have a gf2 as well buits really lacking in dr for my style of shooting so one useful camera only scares me!) I had the money put aside to get the new improved AF all singing all dancing Oly when its announced but all seems quiet on that front at the moment.  So I'd like to get a complementary camera to go with my om-d.  If that is the top at the moment then I guess I will need to hire where needed until the new one is announced and make a decision then.

I've even been looking at the GH3 despite its size, but I can't find anyone willing to put their neck on the line and call a winner!

Thanks in advance for your thoughts!

The only site I am aware of that actually tries to test AF-C performance in a systematic fashion is the French Fnac labs.

In one of their tests, they simulate a car approaching the camera at a speed of 50 km/h. The camera is fired in burst mode with a 200 mm (EFL) lens. At the outset, the car is fifty meters away. Obviously, it gets more and more difficult for the AF system to keep up, the closer the car gets. So one significant measure is the distance of the car from the camera when the last reasonably sharp shot is caught. Here are the results from this year's roundup:

Looks random, like a result of a single try.

To you perhaps.

Not to you?

I see systematic as well as random elements in the results (as pointed out in the post in which I first presented them). A well-known and inescapable random element in photography is photon noise. Nevertheless, our photos don't look entirely random. Have you ever considered why?

Was it a result of statistically significant number of experiments (that would be hundred or so at least)?

Do you really beleive that tracking in 650D is better than the one in 5D3?

No. What makes you think that in view of what I already said about the matter here?
