There's no doubt, the A99ii is a great FF camera and it has seriously challenged and beaten in some areas, the Canikon's, However, its not the sort of camera I would want to own or use let alone afford as I am not a pro, just a happy snapper using Sony cameras at the budget end of the line. I still remain 'confused' as what Sony are planning if at all for the future of APS-C A mount, E mount is not for me, its yet another system you have to support with more lenses some very mediocre and some crazy expensive. This is why I am attracted to M/4/3, its an easy and value for money system that delivers on many levels, plus I love the Jpegs.
I find DYXUM, site good for Sony/Minolta lens appraisals, Its a collective users opinion rather than lab tests and the Sony 18-135 came out excellent with high marks from ex number of users. The Mk 1 18-55 SAM kit lens did perform quite well, read Photozone review, but my Mk2 was so awful I sold it on E Bay. Sony fooled around with a modified rear lens group and cropped rear aperture to remove rear element flair, end result, they wrecked the resolution. In my opinion, the best APS-C A mount kit lens is the Tamron 18-50 F/2.8 (non IS), its easily as good as the CZ 16-80 and Sony 16-50 F/2.8 and an absolute bargain. Even the Sigma contemporary series lenses are excellent alternatives to Sony. You must have had a good copy of the 18-70 as it generally got poor reviews. I might just look around for a used one to try out.
