I just purchased a 800mm f/5.6, what a freaking Monster, takes great shots, but can be a pain to play with..of course it is the 35mm format for wildlife shooting, for some reason, as I get older, I like the distance between me and the Grizz it offers! LOL
I'm not going to ask how heavy that monster is. All I can say is you better hope the kids don't get bored with cow tipping
LOL - you guys are too funny! Of course, you know those gents driving around in those HUGE, gas guzzling trucks... I've always kinda wondered what they were compensating for. <wink, wink> Is it possible that this same phenomenon is happening with cameras??
Honestly, the only thing that's wrong with my Canon T-70 is the rectangular format. I like shooting square more, and I'm still thinking of ways to mask my canon into a 24x24mm. 6x6 is mainly why I moved up to medium format, the amazing quality (and waist level finder) just kept me there. I still shoot 24x36mm, but have a harder time composing in the rectangle. I guess it's just a matter of opinion.
Anyway, If I ever move out of 35mm & MF, it will be for a half frame (24x24) or masked LF...
