quick question

[Pen]

So i currently have a sony A330 and im looking at buying a new camera, and there is one feature that id love to have, mirror lock-up, i know the new A850 has this feature but what other sony's do?, and does my current one have it? (if it does i havent been able to find it )

The A900 also has it ... as described on page 87-88 of the User Manual.

The new A500 and A550 might, but I am not sure. They are kind of new. Their user manuals are not currently available for review.

Thanks!, i thought i read somewhere that the 550 had it, not 100% sure on that one
