I currently shoot with the following lenses on my D90:
Sigma 17-50 f2.8 OS
Nikon 35 1.8
I am looking to add something above 50mm, as I tend to shoot a lot of portraits and have found that the 50mm top end is somewhat limiting overall. I am considering the options listed below. I have given my pros/cons as well.
Nikon 85 1.8G
Pros: Great quality, sharp, bright, lightweight, ideal for portraits
Cons: Fixed focal length, therfore not versatile
Sigma 50-150 f2.8 or Tokina 50-135 f2.8
Pros: Very versatile, 2.8 throughout range
Cons: Heavy, only available used (not a huge deal)
Nikon 24-120 f4
Pros: Very versatile range for my use, constant aperture
Cons: on the heavy side, lose wide end although I don't shoot in that range too much, pricey
If I sell my Sigma to fund the 24-120, then total $ paid will all be in around the same range ($500 - $600).
Any thoughts, suggestions, or otherwise?
