"Hiya Bruce,
It's me again! Becoming a bit of a pest on here! Anyways up I'll give it a shot. I've been looking at Sigma and Tamron 70-300mm Canon fit lenses, and was wondering if these lenses would be compatible with my adapter. I couldn't see any reference on any sites, so I got in touch with Canon and they told me to get in touch with Sigma and Tamron! What! So, I got in touch with Tamron and their reply was even funnier. They said they didn't test their lenses on the adapter, and I'd be better off getting in touch with Canon! Talk about passing the buck! After tis non-information, I decided to not get in touch with Sigma, for fear of another "run-around-the houses" I Just wondered if you could shed some light on this?

All the best,

Hi Terry!

I think you're going to be a trailblazer on this one. LOL. These big companies don't want to stick their necks out on the 100% compatibility issue. If you can afford the possibility of disappointment, I'd dive in and take the risk. You never know without trying out a lens-camera-adapter combination yourself.

I did the same thing with NON-canon extension tubes and they worked flawlessly on all of my Canon DSLR bodies. Whatever you choose, the Sigma or Tamron, treat it gently and you will be able to resell it at a moderate loss if the combination doesn't work to the level you want.

Like I said before, with the 18-55mm, 55-200mm you're off to a great start. I'm banking (no, actually hoping) on the new Canon rumor about a full-frame mirrorless that takes EF Lenses being released in 2018, most likely at Photokina.

Keep us informed. We're anxious to hear what happens!
