Sometimes (today i got it a lot of times ) i am shotting just fine, then all of the sudeen i see the AF stops working and i get a "No lens" warning, I can manually focus, but the f/stops wont move and of course i can't shoot anything since i get a No Lens warning, if i turn off the camera, remove the lens put it back on and turn it back on again 90% of the times it will fix the problem, but sometimes it won't.

For instance today i went on a shooting spree, before i started i made a couple of test shots, got the "No lens" warning about 10 - 15 times after that i went and shoot about 500 shots and no problem whatsoever.

Do you guys think i have a bad lens? or a bad body? or just something on my side?

Sending the camera to service HAS to be my LAST resort since I live in mexico (yay! stupid 3rd world country )

Any ideas?



Thanks

Hey,

Have you tried cleaning the contacts on the lens/body?
Maybe this could solve your problem...

Try cleaning both the lens and body contacts with a pencil eraser.

Did as you guys suggested, and i tried it right after, only gave me the error once, then i shot a few shots, with no problemi don't have another lens to test it, (well i bought a 70-210 f/4 but its nothere yet)

You'll probably need another lens to see if it's a body or lens problem.

It could easily be either one. Wait till you get the new lens. If the problem happens with the new one then it is likely the camera. If the newlens works fine, then it is the original lense.

the mount/contacts are built very 'tight' to allow for long term wear and tear

when mounting a lens try to (gently but FIRMLY) 'snap' it into final position

after the camera 'wears in' you will no longer have the issue

(took six months with my 7D)
