- Sony E-mount
- flange focal distance
- lens cap
It was a perfect fit into my A7II and of course on my A7III!!
This T-Ring is exactly 37mm long which, when you add the 18mm flange focal distance of Sony E-mount cameras, comes out to exactly 55mm. Threads and connections are very smooth, and they even include a nice Sony branded rear lens cap so you can leave it on the telescope and keep your optics protected. Great product from WO!
This T ring adapter fits my Sony ar7ii perfectly. No play whatsoever. Worth every penny.
