Recently I was shooting with my k200d with a sigma 70-300mm tlephoto lens coupled with 2x kenko telephoto converter. The camera stopped taking pictures. On the screen were displayed F--- AND 999.tHATS IT . This is not changing no matter waht I do. I then changed lenses and put on my 18-50mm lens - it worked !!- no camera jam. I put back the telephot lens and it would not work - same message ie F---, AND 999. WHAT IS WRONG WITH MY LENS OR WHAT AM I DOING WRONG?

Have you tried cleaning the contacts on the lens mount? Does it work without the teleconverter? Sounds like something has gone wrong with the contacts and the camera thinks you have a pre-A series manual lens fitted.

Does the lens have an aperture control on it (a ring next to the lens mount)? If so, it needs to be set to "A" to work with a DSLR. It's surprisingly easy to accidentally hit the button and move it off the A setting, I've done it before now.

Is this lens/tc combo new (to you)? In other words, have you used it before without problems?
