Is the Rebel SL3 and Tamron 18-270 Di II VC (B003) incompatible?

I'm a newb Dslr user.

I'm so confused! I have a Rebel SL3 with kit lens. I picked up a used Tamron lens.

I'm testing in Auto. It take pictures fine. But as soon as the zoom ring is advanced to 100mm (and longer) I get completely black images. When imported into a computer, the images are usually black though sometimes I can see very faint shapes.

I asked a friend to bring his old T1i Canon, and the Tamron lens works fine on it at all ranges! Does this mean it's my camera? Hence the post to the Rebel forum.

Photos taken just under 100mm (there are no range marks but I assume around 90mm to 18mm) the images are fine.

I also noticed at 100mm and higher, ISO in Auto is always at 100. It never adjusts or deviates higher or lower. Could this be the issue? I thought ISO was "gain" for brightness and Auto will adjust that.

I took sample photos and snapshots of my camera's display at different ranges. I’ve attached a link maybe it will help shed some light.

My guess would be that the Tamron lens, being rather old doesn't want to work well with the much newer SL-3. You might contact Tamron to see if there's any way to update the firmware on the lens. I doubt it's compatible with Tamron's dock.

thanks for the suggestion. I'm bit disappointed. It's my favorite lens, but I'm just a hobbyist so it's ok if this take a while to resolve.

thanks!

I have and use the Tamron 18-270 on both the SL1 and SL2.  The lens works perfectly on either body.  I haven't heard of any issues with the SL3 so I can't comment on that combo.
