Re: which is the best 70-300mm for A57

Okay, third example, to demonstrate performance at 300mm. Shot last month, hand-held. Sony A580, Tamron SP 70-300mm f/4-5.6 Di USD at 300mm, ISO 400, 1/800 s, f/5.6 (wide open). Obviously depth of field, coupled with the auto-focus system's guess about what is the main subject, really limits what you get here. Here's the full image scaled down at a 100% crop. Files prepared from raw in Sony IDC but without any adjustment, then cubic-scaled or cropped in GIMP 2.8.4 without any sort of post-processing sharpening and saved as maximum-quality JPEG's.
The whole frame:

The 100% crop:
