Some retailers call it incorrectly a M48 T-ring, but we don't call it a T-ring, because a T-ring must have a T-thread, however this one comes with a female M48 thread instead of a T-thread. (A T-thread is a 42mm metric thread with 0.75mm pitch.)

So on the telescope side there is a M48 femal thread and on the camera side there is a bayonet for Sony E-mount.

Optical length of this adapter is 9mm.

If you want to convert it to a short T-ring for E-mount, you might do it by adding an M48 to T-thread adapter ring.

There are two choices... we have not yet tried them, but bear in mind that it would depend on your telescope side connection, which version would be more suitable for your needs.

If you want one with zero optical length and your telescope side T-thread is comparatively short and so it would allow to securely attach it, click here!

If you have a long T-thread and you are not worried about an extra 4.3mm, then click here!

Now, if you want to use your camera with a telescope that features only a 1.25" focuser, add the following T-thread to 1.25" nosepiece. Click here!



Below images show this adapter (365Astronomy M48 Adapter Ring for Sony Nex and E-mount) with the above mentioned TS-Optics Short Adapter with T2 Female Thread and M48 Male Thread and Adapter from 1.25" to T2 with M28.5 Inner Filter Thread. With this combination you can attach your Sony camera (with-E-mount) to a telescope with a 1.25" focuser. This combination is especially recommended for telescopes with short back focus, like Newtonian telescopes. (i.e. Celestron Astromaster, Skywatcher Skyliner etc.)

The optical length in this combination stays the same: 9mm


If you want to attach a FULL FRAME SONY (with E-mount) to your Newtonian telescope that suffers from shortage of back focus, but it has got a 2" focuser, you'd be better off with the following combination. As the subject of this product listing - the 365Astronomy M48 Adapter Ring for Sony Nex and E-mount comes with a female M48 thread, all you need is a  M48 Extension 37mm.

The optical length in this combination also stays the same: 9mm
