Do you find the Imager AF a bit faster on the e-30 also? I imagine the biggest difference is the dynamic range increase. How much beyond the e-520 is it in that area? Im also trying to figure out if it would be good for IR photography, but it seems like each generation of camera (not just Oly) strengthens the blocking filter.
I didn't use Imager AF on my E520, but with the rotating LCD, I recently used it on the E30 at a public event to get shots with the camera over my head from behind the crowd and it was certainly fast enough to get the job done...no complaints here.
The dynamic range is definitley better at 200 & 400, but despite official measurements, not as much of a leap forward as I expected.
It is definitely sharper than the E520 at default 0, but to be quite honest if you turned NF to low, put sharpness to +2 and turned the contrast down 1 or 2....I never found the E520 "soft", as claimed.
