I hope you don't mind a more general question about D100 and Macro.
On the D100, 35 mm lenses are multiplied by 1.5 to reveal the 35 mm equivalent on the digital camera. But what about the 1:1 ratio on macro lenses? How is that affected?
I ask the question because my two favorite and most used lenses on my F5 and FM3A are the Nikon 60mm and 105mm macros. From what I've read, it seems that digital (at least right now) seems to be favored by portrait photographers but not necessarily by those of us who thrive on general nature and micro shots of flowers in particular.
Thanks for any information you can give me on this.
The focal length of a lens isn't really *multiplied* when used on the D100. I think the best term used for the digital effect is "crop factor".
The sensor of the D100 is smaller than a 24x36mm frame. This effectively crops off some of the image as compared to shooting on 35mm film. If you take a picture from the same place with the same lens on a 35mm camera and a D100, then make a print of the same dimensions, it appears that the digital camera used a longer focal length. But you would get the exact same effect if you cropped the 35mm negative appropriately and printed at that same size again.
All that being said, when you focus a macro lens at 1:1, the image on the film or sensor is the same size as the subject you are shooting. At any given reproduction ratio, like 1:1, you will not be able to fit as large a subject into the frame with digital as you can with 35mm.
This can be confusing. Does any of this make sense?
Thanks, Victor, what you are saying re 1:1 makes sense to me if it means the following: I'll still get 1:1 but for a narrower visual field; or, saying it another way, the part of the image that will reproduce is 1:1 for that part.
If my rephrasing makes sense, then my question is answered. If not, I suspect the fault lies in my garbled prose.
