srados: that electronic viewfinder is a deal breaker...Good old prism where are you?
It's really worth giving a shot. Outside of it being different and people fearing change, the EVF on the sony SLT models is truly amazing and gives tons of benefits over standard prisms (not to mention a camera in this price range would have a penta mirror not prism anyway). With EVF you can now: See in low light situations, use viewfinder during video, preview all camera settings WYSIWYG giving you the utmost control over your images, see as much or as little info in finder including live histogram and level, as well as image capture review (huge for us wedding photographers). Plus much much more, just give it a try and you will see how much better it is for the users.
solersala: I agree, too big, too heavy; what a pitty, no longer interesting.
The a35 is still there for those looking for that small option, this just opens the line up to TRY and please everyone.
Edmond Leung: So strange...When compared the JPEG file at high ISO between this new A57 with the NEX-5N, the quality of NEX-5N is apparently much better than A57.How come the image quality of a new product likes that?Sony should make some improvements to A57... At least in par with NEX-5N.
@mick232 - none of those statements are true. The SLT does not reduce resolution and does not cause .5ev light loss. This is the same sensor in both cameras as well as the a35. You can take an a35 and shoot with the mirror up to test directly. I feel there is an issue with these particular JPEG files, but I trust it will be all worked out by final production.
Music Hands: Very sad that they did not retain the compact size of the A55 in the 57. It was quite compact, wonderful value for the size and price. So for the "replacement" Sony makes it bigger, takes away GPS, no sensor improvement, and adds some Bionz chip features?I won't be "upgrading" my A55 anytime soon. I can only hope that the future leads to a more compact SLT design that, again, sets the trend.
The chip is different in the a57. Same resolution as a55 but upgraded to handle heat transfer better for long video shoots.
