EF and EF-S lenses can be used on 400d.
There is a lot of lenses out there.
Yes, the Canon EOS 400D has both EF and EF-S lens mounts. Therefore, the TS-E 90mm WILL fit on the camera because it has an EF lens mount.
Absolutely yes. Canon EOS 450D has the same mount as Canon EOS 400D, wich is EF and EF-S.
Most lenses and mounts are proprietary so no Canon lens would fit a Pentax without some kind of adaptor.
No
The Canon AE1 lens will not fit a Canon digital. You can buy an adapter that will allow the lens to work in manual focus mode on the digital camera.
The Canon EF lens will only fit Canon SLR camera bodies, unfortunately.
Unfortunately, it will not. CANON and SONY have different lens mounting brackets.
NO
NO. The lenses are designed for a specific brand name camera. A lens for a Canon camera will only fit a Canon etc.
Vivitar makes lenses for several different camera mounts including Canon. A particular lens may fit or not depending on the mount.
No, or maybe. You need to look at the lens. If the lens is EF-S then it will not fit. If the lens is EF then it will fit. rebel can use all EF and EF-S lenses. 5d can only use EF lenes, becouse it's full frame body (camera)
It should fit most digital cameras with a normal size lens.
