As I have been extraordinarily good this year, okay, if you insist, saintly,
I am getting myself a Kodak slide projector (#4200).
I will need to get a lens for it. I want is one that projects regular
slides as BIG AND SHARP as possible, from a distance of ten to twenty feet.
I know nothing about projectors, and nothing about photography. SO someone
please tell me what lens to get--I plan nothing fancy...

Before you buy a projector lens, you need to determine two things:
#1 what size screen will you be using, and
#2 how far from the screen will the projector be?
Once you know these two details, most dealers in projectors have a calculator
that will give you the correct focal length of lens.
If the answers to these questions will vary sometimes, then get a zoom lens.
Also, if you a projecting slides in cardboard or plastic mounts, get a Kodak
curved field lens. If you are projecting glass mounted slides, get a flat
field lens, available from a variety of manufacturers.
Good Showing!

Lily,
The projector doesn't come with a lens?

Don't worry about glass mounted slides, most juries won't take them so
if you plan to send slides to juries you shouldn't have your slides
mounted that way.
On the other hand, glass mounts are really nice, very protective but I
stopped getting them a long time ago.
Also, you'll need a carousel with wider slots for them. This also means
fewer slides per carousel.
And those Kodak carousel projectors last and last, mine is from 1978.

I believe that most slide projector lenses are
capable of this. It's the resolution of the
slide itself that is the hindrance to a sharply
projected image. Enlarging a 35mm picture to
8 feet high is a lot to ask of standard photo
techniques. With a good tripod (not like mine!),
a cable shutter release, and the right film,
you will do more to improve sharpness than by
any modification of the projector.

Snail has a really good point. I started taking my own slides about
three years ago after having a pro do a dozen for me. He generously
showed me how he does it, and for a hundred dollars I built a setup
with controlled lighting that comes down out of the rafters when I want
to shoot. One-second exposures on Fuji RTP-11 film, a color-corrected
halogen lamp with strong diffusion, a cable release, and a macro 100 mm
lens make for very sharp slides indeed. I can send a large jpeg file if
you'd like an example. For web pics see my site @

Lily:
What you want is a ZOOM Lens, for the projector. Depending upon the exact focal
length, you will be able to change the image size. The best bet is to go to a
regular photo supply store and talke to them and actually use the projector.
Hope this helps

Why get a curved field lens vs. flat field? Very simple: look at a cardboard
or plastic mounted slide. It's not exactly flat. The Kodak curved-field lens
is made so that the "plane of focus" mimics this curvature and yields a
projected image that is more uniformly sharp from center to corner. On the
other hand, a glass mounted slide is sandwiched between two piecespieces of
glass, so a flat field lens gives the best center to corner sharpness. By the
way, resolution of the slide projector lens is a valid concern, and the
originator of the question is on the right track by choosing a Kodak machine
over other less expensive brands. Kodak's lenses, and most lenses made to fit
Kodak projectors, are of high quality.
