| Latest Review Posted | Sigma IF EX DG HSM 24-70mm F2.8
I recently picked up like-new copies of both the Sigma 24-70/2.8 HSM and the Tamron 28-75/2.8 from two of our longtime members. The Sigma had just returned from getting re-chipped for the k-5 and calibrated. I sent the Tamron back to get it calibrated also so that my AF micro-adjustment corrected the same at 28mm as well as 75mm. As an aside, Tamron did a great warranty job and it came back perfect. So I had two, minty, calibrated lenses to compare and keep the one I liked most. I could not quite get around to creating the data and writing a true comparison of the two lenses but I will refer to the Tamron throughout this review of the Sigma.
The Sigma has an 82mm front element (vs 77mm on the Tamron). If you are an outdoor shooter that new CPL is going to be pricey However If that 82mm is what is required to produce the 24mm short end versus 28mm then I am all for it. I just shot Thanksgiving with this lens and knew that 28mm would be tough to get the big rooms and dining room tables full of people in the frame. The difference in 24mm and 28mm is significant whereas the 70mm versus 75mm long end made little difference to me when composing.
The lens is very heavy and solid feeling (still plastic though) versus the light feel of the Tamron. I am hard pressed to distinguish the two lenses' output at identical settings without a big monitor and 100% view...at least. However the silent and solid feel of the Sigma seemed to increase its value every time I swappe... |
