Imaging-Resource did side-by-side test with A55 and much more expensive Canon 7D and found the predective AF in AF-C mode matched that of 7D.
As for slide mode, keep in mind the slide is 10 fps so it's not slow slide that you can't pan at all. Here is a video of EVF while doing 10 fps.
Oh boy.. the imaging resource side by side with 7D MYTH.
Imaging resource did NO SUCH THING.
Lets analyze what they say they did:
A car with a relatively low speed being shot. We get NO real results, nothing of the 7D. We do get a small set of crops from a toyota logo from the A55v.
Now lets look at the crops. Almost none are really sharp. One is very unsharp. The "reviewer" claims.... camera movement for THAT crop. Camera movement? Really? From ONE shot out of a series of 9... within ONE second??? Right.
So, a camera with built in IS. With high shutter speed. With a relatively short focal length. On a sunny day. Camera movement. The reason for the OOF-ness of ONE shot. Where we can't even see a tell tale camera movement direction in the blur.
No, imaging resource did NOT test how good the AF from the A55v is. At least, if they did test that, they have not published the test. They mentioned a non-taxing lame "test", with no results from what they claimed they compared it with, and with very poor results from the crops of the A55v that they do show. And then they also come up with nonsense to explain the OOF-ness.
Don't take that source (for A55v AF performance) serious.
About the slilde show, the problem is not the slides and slide times themselves, but it is the "seeing what has been" position of a fast moving target. This train is not fast moving in the frame, it is slow and comes towards us, and needs no tracking by the photographer. So it does not illustrate the problem.
The A33 has no 10fps mode, by the way.
