I'm also new to macro, and keen to buy an specific lens. i already got a tripod and remote shutter, but only a superzoom and a cheap but fast 35/1.8 prime.
What focal is best (for DX, I own a D5100) for nature shots of flowers and insects (I'm not sure I am any subtle at all when moving, flowers won't care but bugs...)?
I'd like to use the lens also for portraits, but I'm not sure if it is a good idea.
Example: from your experience, is it wiser to go for
A) Either Nikkor or Sigma 105, both 2.8 and stabilised (in case of handhold macro shots, is it worth it the €800 price tag?)
B) Either Tamron 90 or Tokina 100 + a €200 prime 50/1.8, totalling even less than first
(is it better 85/1.8 for portrais, although €400 and maybe too close to the macro lens focal?)
C) Just 85/3.5 Micro, cheapest choice and with VR, but I have some doubts:
3.5 and maybe too long (127 eqv.) for portraits and slightly short for bugs macro?
Or good enough for both, given I'm no expert photographer (although enthusiastic)
