Promaster Spectrum7 Zoom Lens

I have a Canon EOS Rebel T3i and need an adapter to use with a Promaster Spectrum7 Zoom Lens.

Why? Don't waste your time or money which is likely going to cost you more than the "lens" is worth.

I need to know which adapter I can use so I can attach the zoom to my Canon camera

Yeah, I thought you were pretty clear too. Ha ha. JJ, do you know what mount the Spectrum7 currently has? Were you using it on a different body and if so which one? Sigma, Nikon, Canon, etc. Once you know that then you'll know if it needs an adaptor. Nikon mount to Canon mounting adaptors are pretty common. Your best bet is to take your Spectrum7 to a camera store and get some help across a counter.

Good luck.

JJstewart,

The "why" was not a clarification on which adapter you need but why would you want to adapt a poor lens with an adapter that will only make worse. It is better to spend that adapter money on a lens that already fits your camera.

Totally agree that it's NOT worth doing.

Maybe he wants to use it artistically. So many haters. 🙂

Promaster Spectrum 7 isn't a single lens... it's a whole line of lenses, teleconverters, etc. and they made some of these with "Canon" mount... but also made them for Nikon and others. However... even if it is for "Canon" it could be a Canon FD mount.

It's my understanding that these were actually made by Tamron, Sigma, and Cosina.

Just knowing it's a Promaster Spectrum 7 Zoom isn't nearly enough information.

However... if the lens isn't already a Canon "EOS" mount (all electronic contacts - no mechanical levers on the lens body interface) it's probably not worth adapting it to your camera. You lose a lot of control. Most owners are disappointed with the quality of an "adapted" lens.

"Most owners are disappointed with the quality of an "adapted" lens."

Not to mention the poor performance when used with out an adapter! This is a bad idea all the way around.
