Sigma 150mm f2.8 APO DG EX
Sigma just released a new macro lens called the 150mm f2.8 APO DG HSM (it's quite a mouthful) at a price of $600. I purchased this macro lens based on advice from Wetpixel moderator Craig Jones. It uses an ultrasonic motor for focusing, so FTMF is possible, and it's also an internal focusing lens, so the front doesn't rack out. I believe it is the fastest macro lens at this focal length and working distance. Since I have two 8 megapixel cameras, one with a 1.25x cropped sensor, and one with a 1.6x cropped sensor, I decided to take some test photos to see what the lens is cabable of.
