    I have a Canon EOS 550D and was using a tamron Di VC USD 70-300mm lens for shooting rabbits or something like that. Anyways, the sun was setting and it was so pretty that I decided to take a few pictures of it and didn't think to change my lens. All went well until a few shots in my viewfinder went dark and AF points would not illuminate and, basically, my camera became pretty much unresponsive. Thinking that it was just the new lens I was using, I changed lenses and everything seemed to go back to normal. Thankfully my camera's been alright since but for a while I really thought my camare had died on me Sad Can anyone tell me what happened here?

    Hate to ask the obvious - had live view activated?

    Sounds like the mirror had closed for some reason - hence the dark viewfinder and the non responsive AF points (at least through the viewfinder). Are you sure you didn't accidentally activate the shutter on a long exposure? Did you try powering down and then rebooting before changing the lens?

    Live view not activated as I don't like to shoot using live view on my dslr. Think I did try switchingit on and off but to no avail so then decided to change lenses thinking that it was something to do with the new lens that I'd just bought. Nothing like that has ever happned like that before and I can't seem to find an explanation in my canon instruction book. It probably sounds ridiculous but I was worried, because I'd been taking pictures of a sunset, I thought I'd burnt out my sensor or something, a bit like you do with your eyes if you look at the sun too long, was worried that I'd done permanent damage Sad

    No, no error message came up. and I didn't press the shutter button during a long exposure, I know this for sure as I don't ahve a tripod yet so no long exposures for me yet.

    Maybe the aperture stuck at the taking aperture?

    Was that a one-off event, or does it happen whenever you use that particular lens?
    Don't worry about burning out the sensor, that won't happen with sunset/sunrise shots.

    As noted above it sounds like a bad connection between the Tamron and camera,especially as you say it did not happen with your other lenses.

    If possible it might be worth trying the lens on another body.

    It's never happened again, thankfully and my camera and lens seem perfectly happy together now Smile I was just curious. But I have had error messages come up with that lens though, saying that the contact between camera and lens is dirty or something. But that's only happened about twice and I appreciate that such complicated equipment will screw up sometimes. Thank you for all your suggestions Smile

    If you are getting that error message then it's time to clean the contacts. For start just use a dry soft cloth and polish the contacts on the lens and the camera. If that doesn't work then try a little alcohol on the cloth.

    Hi, was just passing through and thought that I'd mention that it was my lens being dodgy. It's been giving me even more problems and now it's in for repair for about 3-4 weeks Sad Am worried my lens might be a bit of a lemon, anyone have experience of having their lenses repaired, is it likely to go wrong again? I don't mean this question in a psychic kind of way, only that lens are pretty complex and am wondering if Tamron will have nay odea what's really going wrong :-(

    I have a Tamron and i got the same error message. It's a problem with the lens, the contacts don't need to be cleaned like the error message states. I contacted Tamron and then fixed it for free.
