Just picked up a Miranda f2.8 24mm Lens and whilst it fits nicely to both my ME Supers (and Trixie's MV) it won't click into place on my K5 or K7....then it is a bugger to get off.

Any thoughts / advice?

Cheers,
Andrew

Ah yeah Neil, think I may have seen something about that before.

Don't suppose you know of a remedy do you?

Thanks,
Andrew

If it's the ricoh pin, the remedy is to remove it, although some people say it isn't necessary. If you're already having trouble I say remove it.

Removal can be tough because you need to take the mount apart, and they always have an "A" mount, which means there's a bearing that falls out and is unbelievably difficult to get back in place.

The flange that protects the aperture stop down lever on the lens and also the lever itself can also vary in height, on some older lenses it can be high enough to foul inside the mirror housing on DSLRs, check inside the camera around the bottom edge of the mount (around where the SDM contacts are) and look for signs of scuffing.

I have one of these lenses. I removed the pin as per this: link.

Once you get the hang of it, it takes about five minutes (but take your time the first time - and use a proper screwdriver). Make sure you keep the mount and lens oriented while you do it though.

EDIT: The flange on mine wasn't a problem.

It does look like the Ricoh pin, so using the link John sent I will have a go this afternoon whilst awaiting the carpet fitters!

Thanks all, I will post an update later.

1.99 spent on correct sized screwdriver, offending pin removed with ease, lens mounting perfectly!

Thanks all!
