Mattb - Thanks so much for the info, it will defiantly help me make the right choice. And I agree, if my budget wasn't an issue, I should just start with new equipment all together. But I might get more bang for my buck by trying to get one more use from my old glass. Also, I'm not a big fan of auto focus, that's another reason I want to try the old glass again. AF ruins a lot of my current shots, very frustrating, despite my current camera claiming to have a manual focus.
I work as a regional airline pilot, so I shoot a lot through windows, which plays havoc with my AF (Canon G-11). When I'm trying to get the old 'money shot' of a 747 at the critical moment of touch down or rotation, the only thing I need is an finality lock and rapid fire of several shots. Instead, my camera does the old pause and dance between various focal lengths, then finally gets one shot off. If the shot happens to be luckily with timing, then the focus usually completely off, or visa-versa. The G-11 is a good point and shoot, and I like how it travels well, not taking up much room in my flight bag, but falls short on my action shots.
I’m hoping that by using my old glass, I can rapid fire several shots at the critical moment, with the lens simply at infinity, without the camera trying second guessing me.
Once again Matt, thanks for taking the time to provide me with a lot of info to help me make a good decision.
