Tamron - My 90mm Tamron f/2.8 Macro has become erratic

Digital Cameras & Equipment - www.cambridgeincolour.com
I can no longer depend on my Tamron 90mm f/2.8 AF SP Macro Lens to provide correct exposure when using either my 7D, 7D2 or 5D2 cameras. It was working O.K. with my 30D and 40D cameras. The primary problem is when I am using flash but, that is not the only time the exposure is off. Granted that this is the older version of the Tamron Macro and is NOT the Di version.

I shouldn't really complain. I bought the lens, used, for $90 USD about eight years ago and used it right up until I switched from the 40D to the 7D. A Tamron rep told me that they could not or would not rechip the lens to work with the latest issue cameras.

Even using it in manual exposure mode, it is somewhat erratic and I cannot trust it...

I ended up ordering a used Canon 100mm f/2.8 (non-IS) macro lens to replace the Tamron. I am waiting for it to arrive in the mail...
