Hi there ! 

I have Tamron objective 18-200mm DC II A mount for Alpha.

If i want to use it on my camera Sony A5100 E mount, which adapter should i get ?

Thanks for any kind of information.

Sony LA-EA3. It will be very slow at best. Consider getting the E-mount version instead.

As a general rule, I only adapt A-mount lenses which have a strong optical character. Then you can put up with bad autofocus or even manual focus.

For the bread-and-butter lenses it's better to use E-mount lenses that utilise the full potential of the camera.

Thanks for your answer.

So, even if i'll use mainly manual focus, could be too slow ?

Maybe any suggestions which one is for e mount, so i can decide in the future.

At amazon or ebay when i search all i can get it writes for Sony, so i can't be 100% sure, if it's e mount.

Yeah, you're not using the autofocus to its potential and it will be slow and hard to set focus manually with that lens.

Sony and Tamron have 18-200mm lenses for E-mount. It's the same lens and the Tamron is cheaper.
