Re: AF performance a55 vs a77 ?

I see. I guess the Canon shot does seem a little sharper, although you did use a narrower aperture with the Canon lens (which could have made the difference).

But the Canon shot does seem to look a little cleaner, which makes sense because the Canon has a slightly larger sensor with roughly the same pixel count. The a580 does perform very well compared to other APS-C cameras, but I don't think it can beat larger sensor formats when you get to very high ISOs.

Hummers are common here but still difficult because they are so fast. It is always a challenge.

I've seen a few hummers out the window, but I never had time to grab the camera before they left.
