I have a Nikon D7000 with a 18-300 mm lens. This product works just as it should. When I remove the lens cap it hangs down from the lens without getting in my way while shooting photos. This method is much easier than using my pocket for the lens cap.

I bought this filter for my Nikon 16-35 mm lens. It went on easy and I am happy with the landscape images I have taken so far.

This bag is handy. I carry my nikon d5200, a 50 mm lens, a 300 mm lens, and small accessories without a problem. When I need my camera, instead of taking off my backpack, I can just swing it in front of me, grab what I need, and go back to taking pictures. I do wish there was a little bit more space to store my TTL flash, but that's just wishful thinking for any camera bag to hold 2 bodies and 2 lenses.

Screws onto Nikon lens tight. The polarized glass has independent rotation, and doesn't unscrew the base ring. I actually ended up buying two of these, 58 mm and 67 mm, for two of my lenses. Great value for the money, and covers all my amateur photography needs.

This is my first true RF lens for my Canon EOS R5 and I love it! I've been using my beloved EF lenses while renting and saving for the gorgeous but expensive RF lenses like the 85 mm 1.2. I've always wanted a good 35 mm that was sub 2.0, and I've always like macro lenses as well so this fits the bill. It's also pretty compact and light. Usually you can't go into a stadium with the R5 and typical EF or RF lenses because they see the size and think professional camera and they forbid pro cameras. But put the 35 mm on it and they let it slide. It focuses quickly and images are quite sharp. I love the RF 15-35 2.8 lens (rented it for a couple weeks to handle a couple photo shoots). But this lens rivals that lens at 35 mm. It may not beat that lens in absolute image quality but when you factor in the macro feature and how small and light it is and the price this lens comes in at, it deserves a place in your collection.

Having owned the distortion-prone Nikkor AFS 17-35 f2.8D for six years, it was time to switch over to Canon's EF 17-40 mm f4L USM. Canon's version was over a $1000 cheaper, optically superior and lighter in weight. For me, an outstanding standard lens when coupled with the Canon 5D.Vignetting at f4 is minimal. Adobe Photoshop CS2's vignetting tool can correct the vignetting.Distortion at 17mm is minimal. Less than Canon's EF 16-35 mm f2.8L USM set at 16 mm.With the 5D pointed at a blue sky, the EF 17-40 hunted for a focus point while the EF 16-35 didn't.Flaring is minimal when compared to the EF 16-35.Portraits taken at 40 mm produced better results than the EF 16-35 and AFS 17-35 at 35 mm.Images produced at f4 are sharp. At f8, the images are very sharp.This lens is a definite keeper.UPDATE (13-July-2007): Please see some of the images taken with this lens.

It works perfectly on my R6, the lens is very light, focus speed is quick. The noise of STM motor is louder the USM as expected. Plastic material looks cheaper but better than the plastic on the EF lens. Marco function is usable. It is slightly shaper than my EF 16 35 mm 2.8L II at 35mm zoom at all the aperture. Compared to EF 50 mm 1.2L, at 1.8 it is shaper, but slightly less shaper when the aperture is above 4.0. The color is more saturated than EF 16 35 mm 2.8L II at 35mm zoom but less tone than EF 50 mm 1.2L. Bokeh (shape the background light) is not good as EF 50 mm 1.2L. With this price the lens provide a decent performance. No weather sealing around and no lens hood are the reason I gave 4 stars.

These work well with my Sigma and Nikon lenses and lens caps as long as they are stuck to a flat part of the lens cap. There is a little bit of thickness to the foam adhesive, so the surface doesn't have to be perfectly flat. Just be sure that the surface is clean and you press and hold the adhesive down for 30 seconds or so to ensure a good seal.I haven't tried to remove the adhesive side so I can't rate that, but the elastic works well for the Sigma Art 18-35 mm and Nikon 35 mm and 50 mm lenses.
