Just some of you may know that I was searching for a cheap long telephoto lens, and I jumped in for the SMC 400mm f5.6 M42 mount lens. The lens is great so don't let the title scare you.
I have a M42 adapter that is without the spring plate (it born without it, I didn't take it away. For god sake I don't even know that there is a lock spring until recent), maybe that's the reason why this is happen.
Anyways what happened is that I mount the 400mm to K10D and went to a local park to have some test shots. With the lens mount on tripod I was thinking it is secure, however, without the lens-locking pin hole on the M42 lens, K10D wasn't securely lock with the lens. Therefore, when I pick up the whole setup with the tripod and want to carry it to another location. I slipped (thanks to the snow) and K10D fly up higher than me ( I am about 5 foot 8) and land on the concrete road.
K10D has a small broken place on its shell, onbroad flash won't flash (can pop up tho), no more spot meter (center and martix works fine), other than all these, the K10D works fine.
So I search online and found Hinman's blog about making a hole on the lens for the secure pin. I should have read it earlier :P
How to convert Pentax M42 to K mount lens - Hin's Tech Corner
Now I have the secure pin spot created on the lens, while doing that I also add the metal contact for "Focus trip" with kitchen Aluminium foil. Hopefully I can go out again and have another try when the weather gets better. :ugh:
I will post pic of my battle-damaged k10d and what I did to the lens later
