Matthew Saville > The Sigma 50-150 f/2.8 EX DC is still pretty new and a lot of people are wondering about image quality etc. A lot of people are also posting on forums about how soft the lens is at 150mm and wide open. Well that's no surprise, if you view the next image in this gallery you'll see a comparison that clearly shows how soft the lens is, when focused to 3 ft. HOWEVER, that is "at the bench". This is a real-world situation that I thought I'd share- If you back off from 3 ft and head more towards infinity, and if your subject is not a test chart, the images look GREAT. That's the bottom line. This shot right here is such a great keeper and I couldn't have asked for more. The sharpness is right there, the bokeh is beautiful... See what happens when you get out of the "lab" and go shoot in the real world?
Matthew Saville > Comparison between the Sigma 150mm f/2.8 EX DG 1:1 Macro, (top) the newly released Sigma 50-150 f/2.8 EX DC, (middle) ...and the newly updated Sigma 70-200 f/2.8 EX DG Macro. (bottom) I've set both of the zooms to 150mm, of course. As you can see, the 150mm prime is just ridiculously sharp, and if you're viewing the S or M size photo of this test you almost can't tell the difference between any of the 100% crops. A legendary lens, indeed! The 50-150 suffers from a strong softness effect at f/2.8 and slightly at f/4. It's almost as if the image is still sharp and yet soft-focus-y. However this is mostly because I'm shooting at the lens' closest possible focus distance, 3 feet. If I back off towards infinity, the soft effect largely disappears. This means that the lens is still pretty sharp at f/2.8 and f/4, but CONTRAST is shot. (See the next newest image, a screenshot with a 100% preview) The 70-200 does a lot better than the 50-150, but it's still not a prime, and you ought to stop down at least once if you want to shoot close up. The important thing to remember is that by f/5.6 and f/8, these lenses are practically the same. In the end, I sold the Sigma 70-200 because it was too big and heavy, and I kept the 50-150 because I absolutely love having that extra bit on the wide end. And of course I'll never part with the 150mm Macro, it is just way too useful wide open... And plus it's pretty beat up and worn out after ~3 years of abuse...
