## Description

Product Highlights: â¢ Mounts a Vast Range of Vintage Workhorse Lenses to Canon EOS (EF, EF-S) Mount D/SLR Cameras â¢ Upgraded and Enhanced, Generation v10 Focus Confirmation Chips for Increased Compatibility â¢ Enhanced craftsmanship and high-tolerance construction for demanding professionals; Infinity Focus or Beyond Guaranteed â¢ Precise fit and solid all-metal construction with chrome plated brass mounts for secure and solid fit; lens has no play, gap or wiggling when mounted on adapter and no adjustments required â¢ Limited 2-Year Manufacturer Warranty Â Mount Vintage Lenses to Canon EOS Cameras Whether you're shooting digitally or on film, Fotodiox offers the world's largest selection of lens adapters. Mix camera/lens platforms or reinvigorate vintage glass; Fotodiox has hundreds of ways to mount lenses onto your DSLR or SLR camera. Our adapters deliver infinity focus and a sturdy build for lasting quality. From standard to portrait, tilt/shift to wide angle - Fotodiox adapters are designed to offer an inexpensive system that enables you to choose from a vast range of lenses to better suit your needs. Back to Highlights Generation v10 Focus Confirmation Chips One of the problems of using manual focus lenses on Canon EOS bodies is that focus confirmation is disabled. When AF lenses are used - even in manual focus mode - all Canon EOS bodies confirm focus with a green dot in the viewfinder and an (optional) audible beep. However when non-EF compatible lenses are used via an adapter, the focus confirmation is disabled. Unless the camera thinks that an EF compatible lens is attached to it, it switches off both visual and audible focus indication. Focus confirmation chips 'trick' the Canon EOS body into thinking an EF lens was attached, so that the focus confirmation indicators work with any lens attached. Focus confirmation chips are great because: Those old split prism viewfinders made a huge difference when focusing, kind of like your own phase detect focusing system. Without live focus, all that is available is a smooth dim viewfinder Even with live focus screen it's really hard to see when focus is properly achieved on the subject you want. Â For more information, instructions and support; click here to visit the Fotodiox Knowledgebase on the Generation 10 Focus Confirmation Chips. Back to Highlights Enhanced Craftsmanship and High-Tolerance Construction The leaf spring design in the adapter holds the lens tight to the adapter, mimicking the leaf springs in the camera body, ensuring there is no play between the camera and the lens. The all metal design and polished surface are designed to guarantee a smooth mounting experience for years to come. The depth of the adapters are designed to take into account the differences in focal flange distances between the lens and camera ensuring that all lenses, both brand name and third party, will focus at least to infinity (if not slightly past). Back to Highlights Precise Fit and Solid All-Metal Construction Fotodiox Pro adapters are designed with tight tolerances to create a solid, gap free, no play, no wiggle connection with no adjustments ever needed. The precision all-metal construction with chrome plated brass mounts for a secure and solid fit are backed by the Fotodiox 24-month warranty.

Review: Super macro tube lens from fotodiox - Tube lenz is awesome, pictures taken speaks about the quality. Autofocus could have been helpful however manual focus isnt that difficult. No doubt the product is recommendable. All three lens individually and together fix to the camera without any hassle. Cost is little higher side, metal body is one plus point. Thank you desertcart, seller and fotodiox 👍
Review: Good but quite over priced - Good quality. But, this ring don't have any contact pins for camera and lens communication. So, auto mode can't be used. Have to use full manual.

### ⭐⭐⭐⭐⭐ Super macro tube lens from fotodiox
*by R***Y on 20 June 2020*

Tube lenz is awesome, pictures taken speaks about the quality. Autofocus could have been helpful however manual focus isnt that difficult. No doubt the product is recommendable. All three lens individually and together fix to the camera without any hassle. Cost is little higher side, metal body is one plus point. Thank you Amazon, seller and fotodiox 👍

### ⭐⭐⭐⭐ Good but quite over priced
*by V***N on 27 April 2025*

Good quality. But, this ring don't have any contact pins for camera and lens communication. So, auto mode can't be used. Have to use full manual.

### ⭐⭐⭐⭐⭐ Opens up a whole new world of macro...!
*by A***I on 13 May 2017*

Excellent replacement for a close up macro lens. Haven't used macro lenses, so can't compare one to one, but for someone who pursues photography as a hobby (and not a professional who can spend top dollar on equipment) this is awesome. All the segments are metallic (? Aluminium) but light weight and sturdy. It lets you get real close to your subject. No optics here so picture quality is more or less the same. Wide out is the preferred position of the lens zoom/barrel which gives the best result. The lens end mount has a proper lock mechanism (that small bolt like thing)used to release the tube. Both side mounts are well made and seem to be durable. Just align the red dots and screw on. Some important things: 1. Lens release Mech at the lens end is a bit tricky so be careful while unmounting to avoid damage to original lens mount. There's a small lever you pull back to release. 2.You get really close to subject so take care not to end up touching/scratching your lens. 3.When using viewfinder one may accidentally unscrew a tube segment instead of the focus barrel, be careful lest your lens falls off! 4.Steady hand (no stabilisation) and keen eye (no AF) needed. But that's part of the fun here! Anyways I'm really happy and satisfied,as it has opened up a whole new world of macro for me in a very affordable price. Thanks Fotodiox, thanks Amazon. Recommended!! (Will post a few photos later)
