T-Thread Adaptor

[Earl]

The Canon adaptor I uses which allows me to link my Camera to my T-Adaptors.

Is this a M42 also? So i could attach a manual focus M42 Lens using this adaptor to my Camera?

No, the M42 thread is different from the T thread...

You need a M42 to EOS T2 camera adaptor (you'll see them on eBay)

[Cornelius Varley]

A t thread is M42x0.75mm and a M42 lens thread size is M42x1mm

Not alot in it but enough to need an adapter. Its the age old problem though of losing focus at infinity when using an adapter, some of them sometimes have an additional lens in them to adjust for the small extension but normally its just an empty ring.

You might get it in one turn though but at the risk of damaging the thread probably not worth it.
