RX10 vs A65+18-135
In evening twilight, my RX10 is doing a bit better keeping detail than my Sony A65 plus Sony 18-135 zoom lens. At mid-zoom, the match is closer. But fullly zoomed out or in, the RX10 seems to be more clearly better.
Of course the A65 is much better for AF speed. But the RX10 AF is okay.
Here are some examples. The focus is on trees in the center of the image.
