I've already got the 43, which is fairly close in FL, but enough of a difference that I like it's FOV better than the 35. With the FLs so close, it didn't make a lot of sense to keep both and I need wider angle, so the 35 needed to go. Once I get the 21, I'll have 3 nice primes: 21, 43, and 100, which should cover most situations. If I need either wider or longer, I've got my zooms to cover anything wider than 21 and longer than 100mm.
Once I get the 21, then I'll back off on buying lenses for a while and see how the setup I have works for me. I've got other things I'm interested in saving up for including a ring flash and possibly a better regular flash that works with PTTL, neither of which is cheap. Depending on what Pentax comes out with in the spring, I may wind up upgrading one of my
bodies.
There is a part of me that is tempted by the 50-135, but the weight is what turns me off more than anything. I know a good strap can make a world of difference, but the question is will it be too heavy for me to handhold steady? I've got tendonitis in my right hand and it's hard for me to handle holding a heavy camera/lens combo. This would be one of those cases where I'd either have to borrow or rent one to try it out before committing to buying.
Unfortunately, I don't have any money trees growing in my yard, so I can't afford to buy everything.
