Tamron 70-220 big old lens...
I have acquired a big heavy (EOS fit) tamron 70-220 auto focus lens and would like to know if it will work with a 400D or will it kill it?On the lens it says: Auto Tamron Zoom 1:4 F=70~220mm No. 185023Any advice appreciated...

Only EF or EF-S mount lenses will work on Canon DSLRs. if the lens has the older FD breech-lock mount it won't fit. if it has the newer EF mount (post-1987) it will fit although the metering etc. may not work..

Thanks for your response Mike,.

The lens does physically fit on the camera but a lady in my local camera shop told me some time ago that older lenses can jam the camera, is this possible?.

Regards.

I don't see why. The modern EF-S mount is back-compatible with EF lenses. the other way around is a problem: EF-S lenses protrude further into the camera body, and if you used them on an older EF mount the back of the lens would get in the way of the mirror. But using an EF lens on an EF-S body should be OK....

'... its important to remember that digital camera bodies with EF-S lens mounts are totally compatible with all regular EF lenses. However an EF-S lens can fit only EF-S compatible cameras and no others.'.

Define jam. Physically or electronically?.

Physically, no, it can't jam the camera..

Electronically, maybe, depends on the lens. Some older 3rd party lenses are incompatible with newer Canon EOS cameras. But that shouldn't lock up the camera, just give you an err 99 or whatever..

Thanks for all that,.

I have tried the lens on the camera and all seems remarkably good, I've taken some really clear pictures at maximum and minimum magnifications, though you need to be a weight lifter to carry it..

The camera display tells me it's a manual focus lens and indeed I do have to manually focus but the lens says "auto" on it, does that mean something else?.

There is a slider switch with M & A next to the F number adjustment, this seems to lock the iris fully open when off the camera, what does that do?.

I'm sure these are silly questions but if I don't ask I'll never know...

Thanks..

Could be an adaptall lens with auto aperture and adaptall EOS mount..

Could again be auto vs manual aperture. Auto aperture.

Got any pictures of this lens?.

Hi,.

Wow, I appear to have got myself a 1969-1971 Adapt-A-Matic which has an auto and manual Aperture, I found it on this link when I had these details from you so thanks..

It looks exactly the same as the 70-220mm one on the index so I'm assuming it is the one, quite a find I think!!!! amazing it's in such good condition..

I tried to put a picture of mine on this site, but couldn't manage it for some reason, without looking in to it too much, I'm new to all this.....I'll have a look on a thread on how to when I get a spare minute..

I'm really enjoying experimenting with the lens, who would have thought in 1969 that it would be used on a digital sensor camera in 2008? and it seems to take really crisp pictures compared to modern Canon Kit lenses, and it was made without computers!....just wish it was smaller & lighter..

Thanks.

Simon..
