It's possible but it's really not a great idea - you end up with roughly the same pixel density an a700 - approx 11mps Vs 12mps and the metering gets screwed up in many modes because most of the frame is black.
The equivalent lens is a tough one right now... There's strong rumours of a 24-105 SSM G lens - we've found it in Sony product codes along with the now released 16-35 and 70-400 etc, we've seen a manual for it, we've seen it on slideshows alongside other released lenses... But we've still not got it. PMA in March?
The CZ 24-70 2.8 is pretty stunning - still getting used to mine but it appears to have better corner sharpness than a 50mm prime at f8. It's heavy though.
We've got
the 24-105 available, which is nice and cheap, but it's a step down in terms of build from anything G rated or the big CZs. About the same as the CZ 16-80 buildwide - optics are said to be decent without blowing you away.
Finally the old
Minolta 28-135 is making a comeback - ebay only but maybe you'll like it.
Aside from those you've got the usual raft of Sigmas, Tamron, a couple of KMs, Tokinas... Same as you would with any other brand.
