Pentax Shooter, B&H Photo
2 weeks ago
Excerpt: I've testing this lens for a week now and I cannot find any faults with it. I use it on my Pentax K-3 for wildlife photography. The lens is tack sharp at f4.5 through f11. On Pentax equipment,the lens does not have Sigma's HSM technology but autofocuses using the older screw-drive technology. I don't know the reason for this but I found the autofocus to be fast and accurate. I believe it's as fast as my Pentax DA lenses.
Excerpt: OK, so it is not the Canon f4.L lens, but it is less than 1/2 the cost. I use this lens to shoot wildlife, mainly BIF. Tracking with this lens took a while to get use to because of its size and weight. Now that I have used it for a while I love it! The difference in the aperture is so little it basically makes no difference. It is a great lens for the money, and it handles a 1.4X TC very well, making it a 700mm lens. In fact, I hardly ever take the TC off of it.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
Summary: I am an amateur photographer owning this lens for last 3 months, spending every weekend for bird and wild life photography. This is a very good,solid lens. It produces good image in f4.5, and step down to f5.6 very good, f.6 -f8 tack sharp image. I got some excellent shots. Handheld, If you are upgrading from IS/OS/VR lenses. Some learning curve and handheld shooting technique required to get adjusted.
Excerpt: This lens simply isn't very sharp unless it is stopped way down. I felt it was terrible below f/8. If it's soft wide open, why carry around such a huge lens? For about the same price, I picked up a Nikon AF-S 500mm F/4 and it is super-sharp wide open, but is a little bigger. The Nikon is sharper at f/4.5 than this lens was at any aperture and works wonderfully for tracking birds in flight. I returned my Sigma.
Excerpt: I must admit that when I bought this lens, rather than the NIKON 500 f4.5, my expectations were somewhat low. I was greatly suprized at the high quality of this glass. Better than my older 400 f/3.5 EDIF. Get this lens.
Pros: Consistent Output, Durable, Easily Interchangeable, Strong Construction
Summary: The lens was bought to feed the insatiable addiction that is photography, those of you who have this debilitating habit will know what I am talking about, I previously used a Canon 400mm 5.6, however found that the reach was just not quite enough for the birds/wildlife which were my subjects.
