SONY DT 55mm-200mm f4-5.6 SAM Lens SAL55200-2 with Hood & Caps mark 2 ii

[mashedmallow]

Does this lens work on an A5100? I think the answer is no.

You are right mashedmallow,

DT lenses have the A-Mount fitting and your a5100 needs an E-Mount lens

However, Sony do make an adapter LA-EA1 but this is an expensive option unless you have a few A-Mount lenses.
