First let me say that I am a professional photographer that needs tack sharp images. I purchased this lens to use in low profile street stock photography and for landscapes on extra long hikes as it is much lighter than the 24-70 f2.8 GM. I know it is reviewed as being soft wide open and soft at 24mm on the edges. My copy was not sharp at at any focal length in anything but studio light and then at f13 from about 28-70mm. In blue and golden hour for landscapes, even at f13 the dynamic range was so bad, I could not get any quality shots. I just got back from a long weekend to Shenandoah National Park. All shots with this lens were way too soft for pro work and went straight to the pixel afterlife. I ended up using my Canon 24-70 L II with a metabones for almost all of the trip. I really wanted this lens to work as it would have filled a missing void in the Sony lineup. Alas, I just sent it back. Thank you to Amazon for such a customer friendly return policy. I always buy all my pro gear from Amazon. The image is a 100% crop at f11 1/80th on a tripod. Focus on the tree.
