August 18, 201510 yr Hi guys, I am trying to use my Tamron 70-200/2.8 with the adapter and I face issue : no AF at all hoever it works with some other like tamron 180/3.5 macro, minota 100/2.8 macro ..... any idea ?
August 19, 201510 yr Sell the Tamron and buy the Sigma equivalent. It's covers the same range (70-200mm), is just as fast (constant f2.8) and is cheaper. It performs incredibly well on both my A6000 and A7ii with the LA-EA4 adapter. Some say the build quality is not as good as the Tamron or Sony equivalent lenses but I haven't had any quality issues with it.
August 19, 201510 yr Author That's my first issue with tamronall other tamron lenses works (the one I have tried) that's a shameI mailed tamron france about it trying to get an answer
December 4, 201510 yr Hey guys, I have a Alpha a7r and the Tamron AF 70-200 F/2.8 (IF) MACRO 77 mm dia A001 and it does not function with the LA-EA4 adapter but all my other lenses work fine. The other lenses I have are the Tamron macro 90mm, Tamron 70-300mm and they both work absolutely ok. Can someone please tell me how to resolve this, cause this is stupid and extremely frustrating. I now have a lens that does not function with the camera.
December 5, 201510 yr Author Apparently it depends a lot on the version of this lensTamron at some points changed some chips and/or programation inside those chips the result is it is not usable on LA-EA4 (or 2) with AFI mailed tamron, they have nothing to say about it ...
