Human: Taylor Hobson Studio Varotal zoom lens from the 1950s proves to be a challenging mount for modern DSLR cameras! To adapt this lens to M4/3rds or Sony E-mount/NEX cameras, follow these simple steps: 1) Secure the adapter print with 4 M3 screws to attach it firmly to the lens. 2) Bolt the prints directly onto the lens flange using M3 holes. A template is included for precise alignment; if you're not confident in your drilling and tapping skills, use the top two holes from the template and then rely on the adapter for the bottom ones. Drilling these holes won't affect the lens's original functionality. 3) Remove the TV flange to access the lens's inner workings. Unscrew the rear lens block, revealing 3 screws that hold it in place. This will give you clearance to drill and tap M3 holes without compromising the lens's use on its original mount. 4) If your TV88 flange has 4 locating screw holes, don't worry – simply adjust the position of the "new" M3 screws if they're not aligned properly. Version 1 of the adapter wasn't designed with this configuration in mind, but it's an easy fix. 5) Keep in mind that there's no built-in flange depth adjustment on these lenses, except for the rear lens group's screw-in depth. The prints don't have an adjustment either, so you might encounter some slight parfocal error. However, my tests showed satisfactory results with both M43 and NEX versions. 6) Be aware that the lens is too heavy for a standard 3D printed mount, but if properly supported, these prints can hold small DSLRs like the BMPCC, GH4, or Sony A7 without issue.
