Well, the A850/A900 are dual format cameras and can used both FF and APS-C lenses, though you will have to set the mode manually via the camera menu and also use the inner framing marks, so no need to buy a Tam 18-270mm lens apart from which a one lens fits all solution is the worst thing (INO) you can do because it'll likely have both barrel and pincushion distortions at either end of the focal range and the IQ will likely be worse than the kit lens, so you'd be best advised to get the best of both types of lens such as sort WA zoom and an intermediate tele-zoom or tele-prime as IQ will be superior, though unlike APS-C format WA and UWA which are in plentiful supply from all manufacturers, the same is quite different for FF shooters. The Tam/Min 17-35mm and Tok 19/20-35mm are about the only affordable WA lenses in A-Mount with the exception of the Min AF 17-35/3.5 G which is grossly expensive unless you're OK using an M42/M39/MD/MC/Asahi Pentax MF lens type should there be any starting in the 15mm-19mm range.
Have a look at the standard viewfinder screen below with identification marks, though in APS-C mode, you'll get around 11MP which is close enough to the A700 and plenty big enough for larger prints. Just my 2 doubloons worth:
I hope this may be of use.
