Fine-tune your back-focus with Artesky Fine Tuning Rings
This ring kit allows you to adjust the working distances for your accessory or camera, the precision is definitely more accurate than the classic extensions.
The Artesky Fine Tuning Ring fits over the T2 thread of your extension tube, just like a ring!
Our Fine Tuning rings are made entirely of steel
Usage
Perfect backfocus adjustment between camera and accessory such as off-axis guider, corrector or reducer
Prevents threads from becoming jammed (very useful on thin extensions)
T2 threads that are too long can be shortened
