Canon 100Mm Macro Lens

[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.

[62 mm (Front)] This is the best 20mm lens I have seen so far. Thank you, Tokina! I also own Tokina 100mm f2.8 Macro lens, Canon mount. Evaluated on Sony A7 III camera.

[100mm] I own the canon 100mm macro lens, which is great, however I was getting frustrated not being able to get as close as I wanted to certain subjects or details. When I learned about Laowa 100mm 2:1 lens, it really only took a month for me to decide I needed to give it a shot (haha get the pun?). There was a slight learning curve going back to a fully manual lens, but let's be honest, you really should take time to practice and learn any new lens you purchase. In no time I was loving the unique images from this lens paired with my Canon R6.

[+3] I added this to my Canon 100mm Macro lens. Works as expected: double the magnification, no artifacts, great working distance for extreme macro work. Highly recommended.
