Finally.. for some of the camera nuts here... (and nikon users...) what has been rumoured for the last 4 weeks was true

Interesting news.

 

That's good for Nikon users, but as usual the Pentax crowd is still the redheaded stepchild of the photography world.

Fred, what's the difference between lenses made for digital and analog cameras?

 

Optically there is no difference. It would only be the mounting of the lenes, and or the electronic control of the auto focus and aperture control.

 

there are specific lenses geared for APS size sensor... APS sized sensor are smaller than the frame of 35mm film... thus Nikon and Canon (if not full frame) has a crop factor of 1.5 or 1.6 because of this.

for Nikon, lenses that are made for digital (namely the DX line) are smaller, more compact... however, you can't use these DX lenses on a film camera. Regular lenses that are made for film can be used on both digital and film camera

 

Another factor-
When switching from a film lens to a digital lens on an SLR that will allow such a thing, there is ofter a change in lens strength. This change is caused by the difference in distance between the end of the lens and the film plane versus the distance between the end of the lens and the digital sensor. Sometimes this is a nioce thing, such as picking up for free a stronger lens like the example below. The bad aspect is if you had a nice wide angle film lens it may very well be way less of a wide angle on the digital body.

Example-
My Canon EF USM 75-300mm film zoom lens fits onto my digital Canon XT, but it changes by a factor of 1.6, so it becomes a 120-480mm.
