Used with Canon A1 or T90. IIRC, they were well made and a little lighter than the Canon, though I'd be reluctant to bounce one between cameras. ;-) The first sample was distinctly soft in the corners wide open with some CA. At f/4 there was a marked improvement but I never hired it again as I figured I would be better off with a Canon f/4. The second sample was way better and I used it several times. Obviously I couldn't do a direct comparison with a Canon but I think the Canon had better contrast and saturation but there wasn't a huge difference. Both had excellent resolution even wide open. The Tamron came with a tele-converter (1.4x?) but the combo performed poorly compared to a Canon with a Canon TC, vignetting and taking a big hit optically. Also, to use it you had to remove the adaptall mount from the lens, put it on the TC and then mount the lens. A proper PITA. I think there have been several variations of this lens and I don't have a clue as to which models I've used. I would imagine that you lose auto diaphragm with this lens and an EF adaptall mount so it could be a little frustrating, depending on how you intend using it. For my needs I'd sooner have a EF300 f/4 (about the same price in similar condition?) but them I don't have an E-1. HTH CraigZ -- Outgoing mail is certified Virus Free.
