T-Ring T2 Lens Adapter / Adjustment Ring for PENTAX dSLRs

This T-Ring, T-mount or T-2 adapter ring is a connecting ring that links the Pentax K (or other compatible Pentax) dSLR digital camera with other optical devices coming with T-2 thread.

Some might think, what can be the difference between these various simple rings...
Well, there is a difference and it's in wobbling when installed on the camera.
This T-ring has probably the smallest wobbling from all we sell...That might make just that difference that will make your astrophoto much better than with a different t-ring. Of course it's not a huge issue, but when doing precision, long exposure astrophotography, this might be very important that you exclude any chance of changing the position of your Canon EOS camera.
