    for a nikon f75 i have which has a 28-100mm f3.5 on it. i'm looking for the smallest possible 'regular' lens i can find. there isn't a whole lot of difference between a 45 and 50mm, and i'm wondering which would be more practicle in terms of:

    compact-ness [sometimes people don't need to know they're having their picture taken]
    practibilty [how much closer to the subject will i be?]
    price [i imagine a 50mm would dominate here..]

    any comment is cool. thanks

    45 is smaller for sure, but 50 would be cheaper.

    I think it's splitting hairs.

    Can't go wrong with the 50mm 1.8. Also it's cheap enough. Like 100 bucks or so.

    The 45mm is a little different. It is copied from the old 45mm GN. Both have the same 3 element teslar design, metal construction and both are f/2.8. The newer P lens has better, more modern coating. It is a manual focus lens, but had the "D" chip that enables all metering modes on AF bodies. It is very short and compact like the older GN version. It was brought out for sale with the FM3a and is a relatively short or limited production lens. The 50mms are AF and of composite construction, making them a little more fragile and very light in weight.

    Is there anything special about the 45mm optically?

    Hello notelliot

    jstuedle gives a good, brief overview

    * Compactness: the first impression one gets on handling is just how small it is

    * Practicality: "Popphoto" Lab Test states ... the SQF readings were excellent overall, among the best we've recorded for a lens of this type. There was slight pincushion distortion, measured at 0.55 percent. At the closest focusing distance of 17 ΒΌ inches (1:7.4 magnification) center sharpness was excellent at all apertures. Corner sharpness was very good at f/2.8, excellent from f/4 to f/16, and good at f/22. Optimum performance was at f/11.

    *Price: The 45mm 2.8 P is somewhat a boutique lens, expensive and not very fast

    The Doc asks if there's anything special about this lens optically:

    After purchasing the matt black model in 2003 for my backup camera, Nikon's FM3A, i sold my fast Nikon 50mm lenses ... in my view their results could not compare

    No regrets, albiet the loss of speed

    Have fun!

    :)

    I have a 45mm GN, the first Nikkor lens I ever purchased. It was bought in 1969 and I used this as my standard (read only) lens for years. The lens design is simple, sharp and has good contrast. The 3 element Teslar design from what I understand does not lend itself to fast lenses, hence the 2.8 max. aperture. An advantage to me was it's f32 min aperture. I did a little extreme DOF close-up work in school and was amazed at the sharpness of this little lens. I have it converted to AI mount, this lets me use it on my D1 cameras and its still a hoot. It does look a little funny on that big body, almost like I forgot to mount a lens at all. Images shot with this lens compaired to say the 50mm f/1.8 are just a little more pleasing to the eye IMO, it's hard to put a finger on what is differant, just nicer for lack of any technical term. That is not to say the 50 is not tack sharp and a deal for the price. It's just that the 45 is, well .... nicer.

    I was thinking of getting F3Ma with that lens as a MF system. It was a bit too expensive so I went with Canon FD for much less money.
