I bought one in December. I am a returning SLR user as my previous SLR (for those with long memories) was a Canon AE1 film camera.
For the money, the Sony is brilliant. Most reviews seem to conclude it's the best entry level camera.
However, I was very disappointed with the stock lens that came with it (18-70mm zoom). The lens feels poorly made and the image quality was OK, but frankly disappointing versus the £100 compact digital camera I'd upgraded from.
The good news, as someone has already pointed out, is that all the old Minolta AF lenses work perfectly on it, so, thanks to EBay, I have the following collection of old Minolta glass:
35-70mm zoom (£25), 70-210mm zoom (aka 'beercan') (£150), 50mm f1.7 'prime' (£112).
The prices in brackets are what I paid on Ebay for them. The 35-70mm is great value and an excellent lens!
All these lenses give very noticeably better results than the stock lens and feel much better built. The beercan is my favourite - it seems to give the sharpest and most 'luminous' colours results.
The prices for these used lenses, particularly the more desirable ones, seems to be going consistently north as more Sony cameras are bought. So the plus, probably, is that if you 'invest' in the old glass you will be able to sell it for more than you paid for it in the future, should you need to!
The only good thing one can say about the stock lens is that it zooms down to 18mm wide angle, and I haven't yet found affordable old Minolta wideangle lenses, so it stays in the collection, if only under sufferance!
HTH!
