55mm micro nikkor on a digital body

[yucel]

I have a nikon d70s (1,5 crop factor) and I'm planning to modify (add a cpu inside) a 55mm f:3,5 micro nikkor to use on this body.

55mm has 1:2 magnification ratio but since the film (ccd) plane is smaller by 1,5 times, does it mean magnification ratio will rise by 1,5 times.

I know this is the case for viewing angle (55mm*1,5)but guess that it won't be so for magnification ratio since 1:2 size of the real object will still be projected on to the CCD regardless of the crop factor.

I'm confused and any help will really be appreciated.

It will simply go to a 3:4 factor instead than 1:2. Btw, I don't see much the need to put a chip inside a macro lens. AF is almost useless in macro (and focus confirm still works in Nikon digitals) while perfect exposition can be found with a couple of test shots (and better than automatic).

I have used a Micro 2.8/55 on a D80 and focus confirmation works perfectly in Aperture Priority. I did not check the magnification rates though.

I agree with Alessandro, autofocus is not really useful for macro photography.

The chip would be to allow metering rather than AF. Only the semi-pro and pro-Nikons meter non-cpu lenses.

I use a 55mm/3.5 and can't recommend it highly enough. There are some reports that the 2.8 version has a tendency to develop oiled blades more easily. It's worth looking out for the PK13 extension tube to take you closer.

Put a chip into any Nikkor lenses silly idea really.

I think a couple of test shoot really fine, I had no metering on D50 I never missed it. Currently I have metering on Olympus E-1 but most of the time I have to modify manually.

I have the same experiences of Attila, both on Nikon d80 and Olympus e 410. I go on both with completely manual all the time (even if with the Oly I can use aperture priority) and rarely I miss a shot. With automatic exposure I usually have a lot more times that I need to reshot because there are some zones burning or other zones too dark.

I can't speak for Nikons or Olympii, but I get pretty good results with the metering in a Canon and, other things being equal, I'd certainly rather have it than not.

As for the magnification ratio, 1:2 is 1:2 regardless of the camera the lens is on. The difference is 1:2 of a 15x22 frame is a smaller object than 1:2 of a 24x36mm frame; so with the crop camera you will get a larger magnification of the object onto a given size print.

I'll not mod the lens with CPU for AF but just for exposure capability.
I know test shots are OK esp with the ease of using digital but putting a cpu inside a suitable lens is very easy.
I modded my MIR 24N with a cpu and I use it more frequently after the modification because it is easier to use now.
Just compose and shoot and always get consistent exposure.
Anyway I understand that 55mm f3,5 is not a very advisable lens. Though I'm going to mod and use it. I'll also try to figre out the magnification ratio on a digital body.
Thanks a lot for all replies
