Canon Rf 100Mm Macro Lens

[Rubber] Purchased for my Canon 100mm RF macro for easier manual focus - just wonderful!

[Plastic] This Lens is the PERFECT companion to Canon RF 85 f/2 macro lens . Size is JUST RIGHT .. Unobtrusive , yet gives excellent Protection to Lens from Bumping into objects .. and has the Perfect Length for use for macro Photography .. allows you to get up Close to Subject and does NOT cast Shadows on Subject you are shooting .. Canon Quality .. Well Worth the Investment ..

[9.345 lb] Fits my Canon RF 24mm f/1.8 Macro IS STM Lens just perfectly.

[1.53" / 39 mm] I love it for balancing my Canon 100mm Is macro lens with and without extension tubes. Thru bnh I have a rotating tripod collar that works great with it. Waited for years for RTCollar... Should have purchased years ago.

[+1, +2, +4] I used a canon macro 100mm with a +4 Hoya filter lens on an canon 80D camera. Love the way photos came out, had fun photographing the flowers and insects. Close ups are my forte', even with other lenses. I love for my images to pop out of the photo itself.

[Screw Knob] I'm using this to mount a Canon 6D /100mm F2.8 macro lens combination on a copystand. Absolutely solid mounting using 2 of the 1/4-20 threaded holes. The centerline and scale marks are very useful for camera alignment, and the large knob makes mounting/unmounting quick and easy while not interfering with the camera. As always, Kirk quality is outstanding.

[12.3 x 6 x 3"] Using this with my Canon 90D and Canon 100mm macro lens. I shoot the slide in RAW and process in Lightroom - results are significantly better than what I got from my pricey Canon flatbed scanner, so much so that I will redo previous work. It was easy to assemble and put to immediate use. I'm really pleased with this purchase.

[34 mm to 43 mm] Lets me use my 77mm filters on my Canon 100mm f/2.8L macro lens, which has a much smaller (67mm) filter size. It's a lot cheaper to buy one of these step-up rings than another full set of filters. The Heliopan screw seems well-made and has not locked up filters when I attach or remove them.

[0.15 lb] When I bought the Canon 100mm macro lens, the guy I talked with told me something I'd never heard before, that a really good (protective UV) filter is a good thing to have with an elite lens!

[Manual Focus] Picked this lens over a Canon 100mm macro. The extra money is well worth the quality of the pictures. Did a lot of research and the manual focus was the only downside. Once I got used it no problem.
