There is no question of going for the D5100.

A-57 vs Canon 600D

The A-57 has:

This takes the T3I out of my list too.

A-57 vs Nikon D3200

The only drawback I see with the A-57 is the EVF but only in extremely low light conditions. I have been using this camera for the past 2 weeks and its fantastic. It beats the D90 (which is approx 20% more expensive) hands down and rivals/beats the D7000 in all the important areas.

Another point one needs to rememer is that Canon & Nikon make pathetic entry-level DSLR's. Though their Pro SLR's are market leaders.

A57  has 60fps in full HD AVCHD format with phase detection autofocus!! and 12 fps in picture mode :D 

A57 is the best !

I am looking for the same thing but im usually in the park I have really been considering the a57 cause the hd i found this one clip of a bmxer and it looked super crisp.

There is now reason on earth to choose canon or nikon (except pro ones). All the cameras, even 7D or D7000 are worst than a65/a77, so definitely go with the Sony one.

If you hadn't already invested in Nikon lenses, the choice would have been much easier. The A57 seven is by far the fastest shooter and produces better video. The Nikons are better in low light by half an f stop but the Sony's focusing is unmatched. If you shoot a lot of video: the AVCHD (Sony) requires more computer power to edit.

I'd say look at the K-30 from Pentax...  There is no Mic. input, but its fully weather-sealed, which is a must if you'll be around in the snow all day. If you want an external mic. input, then the K-5 would be more for you ($80 more, but lacks the 720p @ 60fps mode).

NOTE: There is a hack one can do to all Pentax DSLRs. This allows 1080p videos to be shot at about 75fps, with 720p pushing 100fps.

5100 anytime mate... anytime and if you have no money constraints go for D7000.. its weatherproof as well.. 

this camera such a fantasic ..
