Are there any issues with newer EF lenses on older EF bodies?

[holetbu1]

I have a ELAN 7n and have thought about picking up a nice EF prime. I have a 20 2.8 USM and 100 2.8 USM Macro, and some middling zooms. I am not sure what direction I want to go right now, but was wondering if I should limit myself to older lenses?

On a related note, I don't know if my camera is too new for 'Film Only' Lenses, like some of the older Sigmas. It is new enough that the blurb says it uses the AF system from the 10D, came out in 2004.

Thank you!

I have not tried it but I see no reason why you can't use any EF lens on the old guy. I would say the older film lenses are not very good and most will exhibit a lot of CA when used on a modern digital camera. Personally I would not waste the money but as a goof off play thing go for it.

Do you develop film yourself? It's not that difficult and takes minimal equipment.

ALL Canon brand EF lenses work on all EOS DSLRs and AF SLRs. Now who who knows about 3rd Party lenses if they work or not. The EOS Elan 7N is one of Canon's last film bodies and it's also Canon's first EOS SLR to support the new E-TTL II flash system. So you can use any EX series speedlite and it will work with it. Note there may be some compatibility limitations on some speedlites which rely on the camera menu to set flash settings. Speedlites with an LCD screen to set settings on them won't have this problem or the older 220EX, 380EX & 420EX will work fine too. The EOS Elan 7N is also a body known not to work with certain older 3rd Party lenses. The camera locks up with an error code if shooting with an aperture other than wide open. I use my newest lenses on my dad's old EOS 650 from 1987 and all of the lenses work as they were intended. Everything with the lens works IS, aperture control, AF and even newer lenses with STM and Nano USM AF motors. These lenses utilize an electronic focus ring. Canon has had focus by wire lenses since the beginning of the EOS system so there won't be any compatibility problems.

ANY Canon EF lens ever made will work on ANY EOS camera body (film or digital) ever made. This includes film, full-frame digital and crop-sensor digital. EF-S lenses are for crop-sensor bodies only (except for a few early crop-sensor EOS bodies that pre-existed the creation of EF-S lenses). It's that simple.

Now, whether a particular lens or era-of-lens  is suitable for your purposes is entirely up to you.
