Upgrade Lens housing- Tokina AT-X PRO 28-70mm f/2.8 For Canon EF mount

thingiverse

The upgraded lens housing in this video is optimized for the Tokina AT-X PRO 28-70mm f2.6-2.8 for Canon "EF mount" lens. I expect the AT-X PRO 28-70mm f2.8 (SV?) lens of the same shape will fit, but I haven't tested it for fit. *To be precise, this is the lens version with the 3rd generation bayonet hood mount. (3rd Generation _ Tokina 28-70 f2.6-2.8 ATX-PRO II (1997-1999) For another type of lens, the lens housing for Nikon mount, please check the link below. https://youtu.be/EVfOJ_CQne8 I was pleased with the unique optical power and robust build quality of this lens, so I bought this lens for an additional EF mount. Compared to the Nikon F mount housing, it is identical except for the rear and lens support. (For Nikon and Canon lenses, the rotation direction of the focus ring is opposite respectively, but the focal length indicator ring is perfect if you rotate to install it.) Therefore, refer to the description of the previous Nikon mount video. To mount the rear housing, it is necessary to disassemble and reload the AF/MF switch on the lens. Since it is fixed with two screws, disassembly and reassembly is very simple, so there will be no difficulties if only appropriate tools are prepared. The lens support of this housing is designed to securely hold the housing by connecting the front and rear housing parts of the lens, and at the same time, it is designed to facilitate attachment of the tripod plate, top handle and other accessories. This is not a necessary part, and it may interfere with the mounting when mounting directly to a Canon EF mount camera without using an extension adapter. In this case, exclude the lens support part. [Other necessary parts] - 23 pcs of M4 x 4mm Grub screws -77-82mm and 82-95mm step-up rings - 8 pcs of M4 x 10mm screws (for fixing the lens support) File sharing is for sharing ideas.
