Ring Wide Angle

[-20 UV] Seems to be reasonable quality. Nice slim ring for wide angle lens.

[43 mm to 62 mm] I purchased this step up ring to use with a wide angle adaptor (Raynox 6600). I love B+W and only purchase their filters and rings as I know they are made of quality materials.

[Aluminum] Able to use the filter without distortion with the wide angle ring. Although a little bit pricer than the regular ring, it worths it.

[0.065 lb] Using step down ring to add a wide angle video lens to my Canon 18-55 mm lens. Creates fisheye effect. Video lens cheaper than true fisheye.

[Aluminum] This ring is needed to use with a wide angle and the Cokin Kit. I agree with another review that it difficult to screw on and off the lens (or lens filter. It does what is intended and works well but DO NOT get it on too tight.

[4 x 4 x 0.6"] Lee adapter rings seem to come in three varieties. A)Some sort of odd plastic which has been milled by a blind man and won't fit. B)Metal (aluminum?) but not wide angle. This appears to be rings over a certain size which leave the plastic ones too thin to be sturdy. C)Wide angle which are all metal and, with one caveat, are the ones to buy and use. The only problem with the wide angle is that they won't accept a clip-on lens cap of the same size as A & B do. For instance, I had a 77mm metal, non-wide angle ring which (together with the filter holder and wide-angle shade) vignetted shorter than about 50mm on my 24-105 zoom; the 77mm wide angle ring shows no vignetting till about 30mm. So why use, other than to save a little money, anything but wide angle rings and risk more vignetting and a ring that won't fit other Lee attachments?

[Aluminum] Using this step up ring lets me use my 67mm filters on my 52 mm wide angle lens so I don't have to duplicate filter purchases. Saves a bunch of money. Works great. No problems.

[Nikon Z] First a big shout out to B&H for their personal recommendation! I wanted a wide angle lens that can accept widely available screw-on filters. I'm very comfortable setting f-stop manually (I set all exposure settings manually during my 13 years as a full-time wedding photographer). I didn't want to add money to a zoom feature. I wanted 15mm or wider. I wanted every penny to go to image fidelity. So, here we are with a lens that is engineered in Germany and manufactured in Japan. I shouldn't be shocked at how good the images are, but they are fantastic! Also, an unexpected benefit -- it is FUN. It's fun to touch and look at. It's fun setting the f-stop on a ring and focusing with the depth of field scale engraved next to it. Since it's wide angle, the manual focus on my Sony a7 whatever is a non-issue: I set the focus ring to the available depth of field and forget it. It's relatively small. It's not a dust-sucker. It feels very strong and turning the focus ring and f-stop are silent with no sliding sounds. Oh yeah, almost forgot, the sharpness and colors of the images are beautiful, gorgeous. I think this lens is my favorite lens of the last 20 or 30 years? It's like my favorite meal at a restaurant -- I have other great lenses but I always choose this one when I head outside! Whoever is involved with the design and manufacture of this lens must take a lot of pride in their work. Many thanks to them. Cons? If I'm being picky, then there's a bit of gentle vignette on the corners, but easily corrected with photo editing software. People who rely heavily on their camera's P setting might not fully appreciate the intrinsic value of this lens? Well, that's it. Hope this helps.

[Glass] Brings terrific ND functionality to an awkward to fit wide angle lens. The kit includes: screwdriver for mounting rear adapter ring, the ring and the filters.

[49 mm] Not vignetting in wide angle
