There might be a chip or firmware upgrade that can be applied. Ask this question on Outdoorphoto forum....I'm pretty sure someone there will know.

I don't really know the canon range, but I think its an issue with auto focus/aperture:

Older lenses doesn't have internal focus motors, and were driven by the body.

Newer lenses typically all have focus motors, so the bodies (especially lower spec/budget bodies) no londer have focus motors.

If you then put an older lense on one of these newer bodies, they don't play nice.

You can try putting the body in manual focus, it may solve the problem.

The second issue is diaphragm control - newer lenses have electronic control (with no aperture ring), so the body doesn't have a control pin. Older lenses are controlled mechanically by the body.

 

Check canon's website for conpatibility tables.

There might be a work around but I wouldn't reccomend it. The old lenses are simply not made to work very well with modern digital sensors. You do see people using the old lenses but usually to achieve a particular feel or effect. One that you could most likely achieve in post if you really wanted to. Any solution you come up with will certainly not enable all capabilities of the modern dslr bodies in term of auto focus and various metering modes. Lens coating have improved hugely over the years and computer assisted designs have made optics possible that couldn't be considered years ago. Massive amount of maths go into the design of modern multi element lenses and huge computing power is needed.

Kinda what I was thinking... probably just not worth the effort...

 

Oh well, guess I have to keep a look out for a longer lens now... :whistling:
