As you can see with my sig, I have the F70-210, but the truth is that I don't use it that much and it's a bit heavy. I could just get rid of it, but it would be my luck that I'd need it and not have it (the max I would have would be 70mm), so my thought is to pick up a M135/3.5, along with a TC in the 1.5x range. With the camera's 1.5x crop factor, the 135 would turn into 202.5mm and the TC would turn that into 303.75mm, which would suit my needs just fine.
Has anybody tried this combo (or something similar)? What do you think?
I have also toyed with the idea of splurging and picking up the DA*50-135 and doing something similar--of course the first idea would be alot cheaper.
Thanks!
