I'm from Spain and I've bought a Canon eos 50. The problem is that it doesn't work with a my Tokina 2.8 24-40 that works well with my another camera, a Canon eos 5 (I think in USA, A2E). I've tried this lens with another eos, the ELAN, the eos 500 and it works well. I've tried the eos 50 with other lenses sigma, tamrom and original canon and all of them work well.

Can you help me please?

Thank you very much.

Not an unusual problem, and one of the headaches you get buying non-Canon lenses. A friend of mine has Sigma 28-70 and 400 APO lenses that work fine on her Elan (EOS 100), but won't work on my Elan II (EOS 50). There are reports of more 3rd party lens failures on the new EOS-3.

All you can do is contact Tokina and ask them if they have a fix for the problem. Some lenses can be upgraded, sometimes for free, sometimes it will cost you, it all depends on the lens and the manufacturer and the warranty coverage.

Hi. I had the same problem with a Tokina 28-70mm, f2.8. My EOS 50 would lock up when I released the shutter. Lens was sent to Tokina. The microchip in the lens (I didn't know they had these!) was upgraded. Result--works perfectly. The fellow I bought the lens from had it done under warranty for free. Otherwise, I think it costs about $90.00 US. I also have an older Sigma 24mm f2.8 lens that does the same thing. Works with my A2 but not with my EOS50. I don't think a repair is available for it.

I believe the problem is only with the EOS cameras that use the E-TTL technology-Rebel G, EOS 50/50e, Elan II/IIe, EOS 3, EOS 1V.

Nothing wrong with your EOS 50. Contact Tokina at www.thkphoto.com for possible upgrade.
