Sigma 10 20 Nikon

[Single Coated] Use it to protect my sigma 10-20 I use with my Canon 30D. I have 6 BW filters. They are all top notch quality at a relatively decent price.

[0.9 lb] I recently purchased this 3 pack of filters after reading other reviews. I used them on a Nikon 10-20 APC lens. These are high quality with no color shift and superb image quality with no degradation of sharpness and no vignetting. The price point is lower than the quality suggests.

[62 mm] I used this on my sigma 10-20mm and it works great to protect the lens!

[4.1 x 4 x 2.6"] I have two of these for my GH4s and have nikon and sigma glass on them. They are simply awesome.

[150 to 600mm] I tested the Sigma 150-600mm Contemporary and the Canon RF 110-500mm against the Sigma 150-600mm Sports and sent photos to some of my friends ... the Sigma 150-600mm Sports came ahead about 80% of the time. I was able to tell the difference so decided that it was the best purchase for the money. I shot a nephew's baseball game and got some good action shots (it was about 10 a.m. so plenty of light - did not use a tripod or monopod) ... I am uploading some bird photos where I used a tripod (at sunset if there is movement you will get some blur) .. I took the sun at sunset just resting on a car door and I took the moon with a tripod and 10 second delay to avoid movement .. I am really pleased with this lens; definitely worth the price .. Hope this is helpful

[Autofocus] I didn't have a wide-angle lens... I do now!.. I took my 10-20 down to a nearby park and I'll let the results speak for themselves. I think I'll keep this one!

[AC Input] I was skeptical but right out of the box using auto key I got the best key in 20 years of doing this. Wish I had this 10 years ago.

[1] It is the perfect range , -10 to -30.. I have a -20 -40 and that was too much. -10 Is perfect for my Zoom H4N

[43.3 mm] This 85mm is a new addition to my Sigma lens set. I already use the 20, 24, 35 and 50, and they are all simply fantastic. First off, these lenses are FAST! 20mm T1.5??? Whaaat? That's madness. Next, they are all incredibly sharp wide open. No need to stop down to get a nice, crisp image. And with the sharpness, comes a beautiful creamy bokeh and great texture and colors. Add to that a (relatively) small size for a cine lens, a nice focus throw/rotation for super accurate focus, beautiful build quality and 8K ready, and you have an excellent tool for many years to come.

[0.135 lb] I have recently upgraded all of my equipment for landscape and night photography. I am a Canon user, faithful to the 5D Mark IV. Before investing in a wide angle lens, I compared the Sigma arts (14, 20, 24mm) with the Canon Prime ~equivalents, read many reviews, and decided that the 20mm was the right quality for price. I am a teacher, so price point was important. This lens is a beast, heavy and stable. I have not had any trouble with auto-focus, although I am using it primarily in manual. Amazing star quality, with some expected comas at the edge of the frame. I bumped up to f/2 to help reduce this. I am very impressed with Sigma Art and glad that I did not spend the extra $$ for the 14mm. The photo was taken in March, right at the start of Milky Way season. If you are debating between the 20mm and 24mm, I would definitely go with this one (the 20), because with cropping in post-production, I would not have wanted more of the night sky cut out of the shot.
