strange Lens question

Jun 22, 2005 2:49AM PDT

sorry this is going to sound weird, but i've noticed that for some lenses you turn the wheel clockwise to zoom in (e.g. for the Nikon D70), whileas for other lenses (eg Canon)you turn anti-clockwise to zoom in.

i'm more used to the anti-clockwise way, and was wondering then if i need to buy a Canon camera in order to do so. in other words, i probably can't use a Canon lens on a Nikon camera right?

do different brands have different turn directions?

It's either a hemispere or patent issue.

I have never heard anyone state a preference for which way you turn the zoom ring. That is not the type of information they put in the specifications of a lens, so I can't say if all lenses of a certain manufacturer turn different that the lenses of anothere.

If it is true:
As Bob said, it could be a legal reason.

You are correct, you can not use a Canon lens on a Nikon and you can not use a Nikon lens on a Canon.

Well, you can use Nikon lense on Canon DSLR camera, and likewise. However, not every lense's functions & features ( such as automatic focus ) will work on the other brand camera. Besides, you'll need an extra mounting device, for instance Nikon lenses mountion on Canon DSLR camera. There are some pictures shooting by using Nikkor AIS 105mm f/2.5 using mounting adapter ( cost around $ 50-100 )on Canon EOS 20D. Visit the website :

Canon EOS 20D along with Canon 70-200 F2.8L. The picture quality as you saw on the previous pages is outstanding, some pictures shooting by Nikkor are even better than that of Canon Lenses..
