Guys, another request.

Could you post your serial numbers (I don't need the last 3 digits so you can put xxx for the last 3), and also post the date when you received/purchased it.

thank you!

Mine is 005xxx. I'd assume mine had the updated firmware. Bought it used so I'm not sure; if I understand the only way to know is by sending it to Tamron correct?

Mine's actually 020xxx, so it seems pretty recent.
Still, the 5DIII center point issue is puzzling... Tested my wife's T4i with the lens, works perfectly. I also have a 5Dc but I'm sure that will also work perfectly with the lens.
thank you for the responses.

Yup and mine was part of the first batch that 002XXX I had issues with my 7D so I send it after that no more issues it's been great ever since.

Yeah, it works fine on my 70D too. The first one I had a year ago had issues on this same camera.

Anyone else using it with 5D3? Any center point issues when focusing on bright subjects?

Mine is 001xxx

I went to the park closer to our house today and saw this Bald Eagle.

Cool eagle!

This Killdeer was on the roadside on the way home today. Not often I catch them in green grass. I thought it made a nice contrast with the colors of the bird.

Mine is 000xxx, Purchased last Jan. Had firmware update done.

Mine 011 working great with the 6D but not on 7D. It's not even close in sharpness. =(

017xxx, last august, no need for the firmware update, great on the 6D and 7D.

006nnn April 2014. Works fine on 6D, AF is fine but seem to lose sharpness over 400mm on 50D, very fast AF and sharp on 1D4.

Has had firmware upgrade (also had USM drive replaced without knowing anything was wrong with it - apparently it was showing some signs of heating up when inspected at time of firmware update)

Thanks again guys. Mine is for sure new firmware then.

Nice eagle! Close to home too!

Man, real nice colors, contrast!

My Tamron was purchased in March 2012. Serial # 005xxx. It had trouble with the 7D AI Servo and AF. So I sent it back for the firmware fix on lens and now with my 7D Mark 11 it is great, very fast focus!
