Quantaray 251664736 compatibility

yes it is compatible

You did not mention which lens. Some Canon digital cameras will only take EFS lens, others take both EF and EFS. Also there are other types of lens mounts made by Canon.

Cordially,

If your lens is a EF mount and your digital can take EF lens the answer is yes.

Cordially,

Almost all early Quantaray lenses (and Sigma lenses, Sigma made Quantaray) in the Canon EOS mount will show error messages on Canon digital cameras (but still work fine on older EOS film cameras). usually err99 but err01 also. There is no DIY fix and Sigma ran out of update parts years ago. Current production lenses and Canon made lenses will not have this problem. This lens would only work for someone shooting EOS film cameras with no intention of "upgrading" their system to digital Canon cameras in the future.

Quantaray makes lenses with many different mounts. If the lens has a Canon EF mount then it will fit your camera. If it has another mount, Nikon for example, then it will not fit your camera.

Quantary makes lenses for a variety of cameras. A lens for a Minolta, for example, will not fit onto a Canon. Assuming you get the lens with a Canon EF mount, then yes, it is compatible with a Canon digital SLR.

Quantaray makes their lenses with a variety of mounts. If the lens has a Canon mount then it will work with a Canon Rebel T2i. If it has a Nikon mount then it will not.

The Quantaray lens is not compatible electronic wise with your Canon. It is indeed made to fit Canon, but the lens is a bit outdated compared to the relatively new Canon.

Quantaray lenses were sold by Ritz Camera (also Wolf Camera). You would want to take it in to the and see if it can be sent out and re-chiped, which will allow it to work with the newer Canon cameras.

Not all lenses can be re-chiped. You may just have to purchase a new lens.

Most Canon Digital SLRs use the ETTL metering system. I can't find any decent specs or manuals on the net about this flash whether its ETTL or TTL. I could find models that are specific to Canon and Nikon, so check that first too.

Also be wary of the flashes trigger voltage. A voltage too high might fry the camera when its mounted on the hotshoe, so see if you can find it in the manual.

You can always use this flash off camera in full manual mode. To find out more go to www.strobist.com or go to the Strobist Group on www.flickr.com
