I love buying vintage lenses, I bhought a Adaptall-2 Tamron 80-210mm F/3.8-4 Zoom lens last week at ebay for 15(!) dollar, just received it and it's like new, buttersmooth zoom and focus and not a single scratch on the lens. I know it's not the fastest lens but I"m sure am going to use it at weddings during the reception to shoot talking heads as it's faster at the long end compared to my 18-200mm stocklens on my nex-ea50.

I"m still waiting for the adapter but the lens came with a adaptall to nikon adapter and I had a nikon to eos adapter lying around here so I placed those 2 on the lens and then put those on a eos to mft adapter and it worked :)

I also have a Adaptall-2 Tamron 35-80mm F2.8-3.8 macro that I got a few months ago but didn't get to buying a adapter yet, just did some quick shots and both are very sharp lenses edge to edge, still waiting for a no name battery grip including 2 batteries and a charger that I got from ebay as well for 99 dollar, after that I really can start using it at weddings as I only have one battery now.

I"m off for a one week holiday to the north part of france soon, will only take these 2 lenses and the gh3 with me, excited to see how they perform in real life, will post the video once finished.
