Showing 1-10 of 14
Amazing potential but poor focus

Excerpt: I've had two copies of this lens thanks to B&H's generous exchange and returns policy. Neither could autofocus effectively and the second copy had very jittery and slow live view focussing problems. I tried fixing the focus issues with the in-camera adjustment but that wasn't successful for either lens.
Pros: Good Color Saturation, Good contrast, Nice Bokeh
Excerpt: The built quality is great. It's silent and sharp. What bothers me is how slow the autofocus is. So slow I can't use it for a real job where fast AF is a must. Also it's bulky and heavy...not comfortable to carry around all day on your neck for sure. Thinking of returning it and get a real pro lens.
Excerpt: When the stars all align and there's a lot of light, some shots will be tac sharp; otherwise, you will experience softness... Inconsistent AF; noisy and slow-hunting at times. Disappointed with this Art lens offering.
Excerpt: This is a follow up to my enthusiastic review dated 3/31/14. After a few weeks of use, the lens began to have focus issues, enough to the point that it could not focus on an area that was clearly defined, with easy to discern colors. The lens took to "hunting" back and forth searching for a focal point. I purchased the USB Dock to try and calibrate it myself, but that task was tedious for a lens that should come ready to use.
The Sigma 18-35mm f/1.8 From an Astrophotographer's Perspective

Summary: NOTE: This is a review for the Nikon mount of this lens mounted on a Nikon D7000, from an astrophotographer's perspective. The lens was rented from a local camera store, and I confirmed with them that I was the first customer to rent it. Therefore the review is accurately based on a new and unused lens as one would receive from Amazon. I recently rented this lens for a 5-night observing run on Mauna Kea in Hawaii.
Not as good as other reviews mentioned. Perhaps, I got a bad copy...

Summary: I was very excited when I was informed that the lens was available and I would get it in a few days. This excitement quickly turned into disappointment after taking a few shots with this lens. The first shot is very blurry. It is so bad up to the point that it is like out of focus. I said to myself: Ok, this was probably because the lens doesn’t have IS, and the shutter was just 50.
Summary: + Hammer Verarbeitung + Optik, sieht einfach genial aus + perfekt für SLR Video auch bei wenig Licht oder in Räumen - Abbildungsleistung ist nicht wie beschrieben. Im vergelich zum Canon 15-85mm IS USM (was diesen Bereich ebenfalls abdeckt) bei Blende 4 und steigend hat es deutiche Schärfeprobleme. Das Canon ist um Welten schärfer! - AF Probleme!! 5 mal den gleichen Punkt focusiert, 5 unterschiedliche Punkte wurden tatsächlich anfocusiert.
