Wide Angle Sigma

[Aluminum] I do architectural work and before finding about WonderPana, I seldom used my wide angle lenses such as the Sigma 12-24. Now, they are integral part of my main lens kit. Being able to put a polarizer or a ND filter in front of the lens has changed my options dramatically. It is indeed a wonderful accessory.

[82 mm] I bought this filter for the Sigma 10-20mm ultra-wide angle lens. This filter does an excellent job protecting the lens as well as reducing the effect of glare from the sun. I use this filter in conjunction with a circular polarizing filter. I noticed during my last shoot that dust particles tended to collect on the filter, but with the proper lens-safe cleaning brush, those particles come right off.

[0.05 lb] Sigma may be the only company that makes a lens hood to fit my Signma 10-20mm wide angle camera lens. I lost my lens hood for this lens. This lens hood prevents lens flare as well as discoloration of the image due to too much stray light. It's easy to put on and take off. I would recommend this lens hood for a Sigma 10-20mm wide angle lens.

[67 mm] I bought this filter for the Sigma 10-20mm ultra-wide angle lens. Although it is a little pricey, it is well worth the money. It has a carbon / metal-like frame with very high quality glass. I do not really notice any differences in terms of lighting that some people are concerned about when using the polarizing filters. I use this filter in conjunction with a UV filter.

[FUJIFILM X] I've been using Fuji XF 35mm f2 for mostly but I've been wanting a little wider angle lens for some time. Then, XF 35mm are now unavailable for both f2 and f1.4, so I looked at Sigma. Since I love Sigma 30mm f1.4 DC DN very much, I decided to get this one. It turned out to be a great decision. The pictures turn out so clear and beautiful. The angle is great, not as wide as 16mm, but wide enough to capture a lot of scenery, and the whole body of my dog easily. The only concern was its weight, a bit heavier than I'm used to on my small T30II. But once I started using it, I didn't find the weight a problem at all. It's not WR, but I don't take pictures when it rains. I highly recommend it.

[0.05 lb] This is my second Sigma Lens. Great quality. The 18-200 range is perfect for wide angle to telephoto needs. I could not do what I do without this lens.

[Black / Blue] Have only had it for about a week, but every lens I have tried focused correctly, including a very old Sigma 15mm wide angle lens. All Canon lenses worked as designed.

[49 mm] Not vignetting in wide angle

[Autofocus] great wide angle

[Glass] Awesome filter for my wide angle.
