Thanks again. Does the weather sealed Sony 1650 require an A77 to function as weather sealed *lens*? One thing I now know is that I do not shy away from taking my SLT on hikes, exposing my gear to moisture (run, waterfall splash etc.). For that reason (and the dual-dial, now that I shoot in full-manual more often than AP/SP), I am tempted by the A77 with 1650 "Kit". On the other hand, the A77 is almost two years old, making me wonder if an update might be out sooner than later. In which case I'd be tempted to buy the 1650 and stick with the A65 for a while longer. But I wonder if an unsealed body can compromise a sealed lens.
