Cant get converter off lens

[ev]

Hi,

 

Now this is going to sound really silly.

 

i just bought a sigma zoom lens 100mm to 200mm (secon hand). it came

with a converter Komura I think its called.

 

Now I got both lens off the camera. (a Nikon em). But now I cant for

the life of me get this little converter thing of the lens.

 

I cant seem to find any buttons to push to get it off, and its

driving me up the wall.

 

I hope one of you out there can help.

 

Thanks Evelyn in oz

 

on the converter thingo it says telemores95 k.m.c for al. Then

theres a number 3869.

 

If that helps any,

All Nikon fit lenses and converters should have some means of releasing the sprung pin that locks the lens into place on its mount.<p>I suspect that this converter is either NOT a Nikon fit one, or the release button has been broken off.<br>Most manual Nikon fit lenses and converters say N, Nai, or Nai-s on them, not 'al'.<p>Have a look for a hole or slot in the body of the converter, where a lever or knob or button might have once been.<br>Even if the release button has broken off, there should be the remains of a shaft that can be pushed or levered with a small screwdriver or something to release the lens.<p>Of course, if the converter is the wrong fitting, there may be no easy way to release the jammed pin, short of dismantling the converter or lens.<br>If that's the case, take the whole thing back where you bought it, and let them sort it out.

Take it to a repair shop and never use the converter again.

The problem could also be with the lens. There have been problems with old Sigma lenses getting stuck on some Nikon bodies. I think that the EM was one of them.

 

I was once looking at a 500mm mirror Sigma lens at a swap meet. The vendor mounted it to an FM or FM2 and when I decided to buy it, could not get it off of the body. He asked if I wanted the body as well.
