Regarding lenses

<p>Can we fix a Canon lens into a Nikon camera or is that it, a camera requires the lens of the same company? A big doubt!</p>

<p>I am sure that adapters for Canon FD or EOS lenses on Nikon MILCs exist.<br>

In general it makes more sense to get lenses made for the camera you are using, since adapters don't couple AF functions or transmit the mechanics to operate the aperture and also don't provide power for in lens image stabilisation.</p>

<p>Do not forget infinity Focus!<br>

Canon lens mounts are closer to the image plane than the Nikon Flange distance; so if you use an adapter for canon lens to Nikon body it would not be able to focus to infinity unless it contains a corrective lens, and if you use one of those adapters with a corrective lens to allow for infinity focus, it would undoubtedly be a focal length multiplier too .</p>

<p>Aditya, please check the archives, there is a lot of info about using lenses of brand/type A on body of brand B.<br>

Unless you know what you're doing I'd advise against it. In general you loose all automation: autofocus and auto aperture and then there is the issue as the flange distance as mentioned by Dan. So if the lens isn't too special/expensive: trade it in for a fitting lens and you'll be much happier. <br>

Two exceptions: if macro is your thing an adapter may act as an extension tube and give you the opportunity to do macro work. In that case you'll use autofocus anyway.<br>

And second: with MILC/EVIL cameras it is much easier to fit a lens from another manufacturer but you'll still loose auto-everything. <br>

By the way, keep in mind that Sigma, Tamron and a few other companies make lenses for each of the major brands. </p>

<p>See Bob Atkins' most useful post about adapting from one kind of lens <em>mount </em>to another ( http://www.bobatkins.com/photography/eosfaq/manual_focus_EOS.html ). Although it says it's about adapting TO EOS, the charts work both ways, of course.</p>

<p>In general, of the APS-C and 35mm size format cameras, EOS is among the easiest to adapt to use other mounts. Nikon is among the most difficult because of its long distance from film to base of the lens mount.</p>

<p>As Jos says, it is far more difficult to adapt lenses from one mount to another so AF and so on work. The story is manual focus and aperture only.</p>

<p>Summarizing what others said, simply don't waste your time or money.</p>

<p>Several factors: are we talking Canon FD or EOS? Is the Nikon film or digital? If you have several lenses, especially expensive ones, it might be worthwhile to look for an inexpensive used Canon body to use with them. If it's just one lens and not an expensive one, it would be better to just find a similar lens in Nikon mount.</p>
