I'm poor. I've been using a manual Tamron SP 90 with 2x teleconverter on a T1i for insect macro shots. I learned pretty quick that handheld shots were a waste of time with the 2x, so I went with the straight 90 and had better luck. But its still less than perfect. Most of the time I'm too lazy and carrying too much other crap already (binos, insect net) and I hate bulky gear so I'm only using available light too. Although I still have aspirations to do pro quality work on occasion and I'll need to use a tripod and or flash for that, for the moment I just want to improve my good/not good ratio and illustrate a blog and website with sharp images that don't suck.
I know I wont want to use autofocus as a general rule for macro, but wonder if it wouldnt help me rattle off a bunch of shots as I'm moving in for a close manual shot. Although I'm a pretty good insect stalker sometimes as soon as I'm in the perfect position for a manual shot the insect is gone. I've long wanted to get the Canon 100mm F/2.8 Macro USM EF (the L is out of the question) and eventually I will, but since budget is very limited I'm also wondering if the 60mm might be the better choice for me right now. I can save at least $100 on a used lens going with the 60, but more importantly is it the better choice for what I want?
