Mine is the APS format sensor (2/3). With the Sony, I can't get into a full frame sensor unless I go really far up in the model lineup. Way outside my budget, although I still look at them when I start dreaming.
The only drawback to the new 17-35mm is that I have to buy yet another circular polarizer, due to the 82mm thread.
My last lens purchase was a 24-105 a few months back. Prior to that, I hadn't purchased a lens since 2003 or so, when I bought a newer Maxxum film camera, and ended up getting a 28-80 and 75-300. I still have a 50mm/1.7 prime lens, plus the 28-85 with macro, and 75-300, from the old Maxxum, which are far heavier. The 75-300 was also not a Minolta lens. It may have been a Tamron.
I think it's easier for us "old timers" to use the 35mm-equivalent focal lengths. I certainly relate to it easier!
