Showing 1-10 of 15
Not a bad lens for the price
19 January 2013
Summary: Rather than spending a lot of money for the highly recommended Nikon super wide or the Canon, I opted for this model. This gives me the opportunity to experiment with wide angle photography to see if I like it and how much I will use a wide angle lens before committing to a more expensive lens. This does have some chromatic aberrations but overall the quality of the pictures are very good. The lens seems to be solid and well constructed.
Summary: I am just not satisfied with the IQ it is heavy and big and not that great compared to many super wide angle such as the fisheye The IQ gets better when I stop down to f8 and f11 so think carefully before you get this lens
Summary: I use this lens on a full frame camera (D700) - so the review is geared for full frame users. There are wider choices (with relative advantages / disadvantages) on the cropped sensor side - don't get this lens for DX. Pros: - the widest rectilinear lens for full frame. The difference in coverage between 12 and 14mm (the next closest candidate, at least for Nikon) is HUGE (from looking at it - at least 15% - 20% more on 12mm). - vibrant color rendition.
Summary: Sigma has been much maligned by the Nikon-brand lens snobs, and not without good reason. The build quality and optical clarity of the average Nikon lens easily trounces the average Sigma. This particular Sigma lens has been in my bag since 2004 (three years now) and has performed flawlessly in dusty, humid, and rainy conditions. I can't say that about every Nikon lens I have owned. Don't get me wrong-- this is not a flawless lens.
Conclusion: It sure would be nice if Sigma had just made a good 12mm prime and let it go at that. For anything beyond 12mm I use my 17-40L. And it's too bad Canon doesn't offer a really good 20mm prime.
Pros: Half of this lens is great. Very sharp for the money. Very little distortion. The right side of my images are terrific.
Cons: The left half of my images are soft. I returned my first copy to Samy's (with some grumbling on their part) and the second was just the same. Good on the right, bad on the left.
Conclusion: If you want wide, this will give you wide. In fact, for those that shoot the Canon 1 series, your only choice for ultrawide zoom is this one. I don't use this lens very often, because it's rare for me to need to shoot that wide, but when I need to get an entire room into a shot, or need anything wider than the 28mm end of my Tamron 28-75 DI, my only choice is this Sigma. The build is quite sturdy. No complaints there.
Pros: It sure is wide! Feels quite sturdy.
Cons: Stupid rear filter design. All my other lenses are sharper.
Conclusion: I use this lens pretty much as a 12mm prime, I hardly ever touch the zoom ring. I also shoot almost exclusively at F11 - F16. F16 seems to be the sharpest stop. The lens was a bit larger than I expected, it doesn't fit in my camer bag (it comes with it's own bag though). The pictures on-line make the lens look small (even when it's mounted on a camera) Positive: I love the construction, it's a very solid feeling lens, and a joy to shoot with!
Pros: solid construction, great feeling controlls good performance at F16, not much distortion
Cons: not very sharp anywhere near wide open, a bit tricky to use
Conclusion: Camera: Canon EOS 10D Primary Use: Wide Landscape Photography This lens could use some improvements. If you're really looking for the widest possible rectilinear lens, then this is your answer. I really see no point in making this a zoom. The lens could possibly benefit from it by just being a single-focal 12mm. Image quality: 3/5 (It's decent, but not mind blowing. Be careful of lens flare. Vignetting occurs when using the filter mount.
Pros: Wide angle capability. Nice case.
Cons: It's a zoom - Sigma should have just focused on making it a wide prime. Bad design on the filter mount. Sub-par finish feel for a pro lens. Front element moves when zooming. Uber slow AF speed. Mediocre image quality.
Conclusion: I've had this lens for one weekend for testing. First I was VERY disappointed when I saw my studio photos of a resolution chart: unsharp corners, a LOT of chromatic aberations in the corners, average sharpness. But after I took some 'real-life' photos, I wasn't disapointed anymore: nice colors, not very much distorsions, chromatic aberation not much visible. I don't know if I should recommend this lens or not: stopped down to f/8 or smaller (e.g.
Pros: Extremly wide (12mm), quiet focusing (HSM), nice color rendering, average/good focusing speed, in the center relatively sharp for such a wide lens
Cons: not very sharp in the corners (even stopped down), a LOT of chromatic aberations in the corners, very large (82m) thread size
