Cheap M42 extension tubes

[coldlegs (Stephen)]

Found some cheap M42 extension tubes on ebay.
For about $12 dollars you get six (7,14,28 + 9,16,30mm) which
gives the following extensions.

7,9,14,16,21,23,25,28,30,35,37,39,4 2,44,46,58mm (missed a few!!)



7-14-28 $5.39

I'm guessing those are for the M42 lens mount (1mm pitch), not the T-mount (0.75mm pitch)?

I tested the 7,14,28 on my name brand extensions and they fit fine so at
least the 7,14,28 are M42/0.75. Will check out the 9,16,30 when they arrive.

Nice Stephen - would be interested to hear how you go when the 2nd set arrive too.

Alas they are M42/1mm...but..the first set I've got (7,14,28) have only
two and a bit threads which allows them to screw fully onto an M42/0.75 adapter. Might still be useful. Will check the others.
