Is it not possible to run a movie backward on this? I mean, just wanted to go a little back, but it starts rewinding :-)

Mine came with a fixed lens ... Bought an adaptor, so now I have a zoom lens on it ... Nice machine and the slot loading is absolutely fabulous. Love it

It wasn't just Elmo. Just about all 16 millimeter projectors came with a fixed 50 millimeter lens. A variable zoom lens was an optional accessory.

Yes Winbert.As Janice has already said, nearly all but the most expensive portable 16mm projectors only came with a fixed focal length (usually 50mm) standard lens, as standard.
Zoom lenses were an optional extra.
The Bauer P8 for example, is one such projector that would have been supplied with a zoom lens straight out of the box.

quote: Simply cost. Zooms are always more expensive.
Having been in super 8mm collecting for years, this is amazed me. Every 8mm projectors I knew came with variable zoom lens and the projector's price is just so so. We can an expensive 1.0 lens or just the common 1.3, depend on your budget.
Is it different in lens type, quality, the way of making for 16mm variable zoom lens?

Winbert...Here is an inexpensive way to add a variable lens to the Elmo 16CL.
The lens I used was from an Bell & Howell MX33. B&H made several models of this projector. Most don't work now so should be easy to find a machine for almost nothing.
Next... order an Elmo 16CL lens adapter from Shapeways. It was designed by one of our own Forum members, Julian Baquero.
There is a small thin plastic tab that protrudes from the black barrel of the lens. There is an opening on the adapter to accomodate this. However the black tab sticks out about an 1/8th of an inch preventing insertion into the projector lens mount. I just sanded it down to be even with the edge of the adapter...you could also just clip it off.
Here is the lens in the projector. Granted its optics are not as high quality as an original Elmo ... but it isn't bad either and a very frugal solution.

Winbert If you compare 16mm zooms to 8mm you will see that the 16mm zooms are obviously heavy precision made lenses. Most 8mm zooms are made of plastic and not of the same quality. However it is not always the case. There are some 8mm zooms of high quality - like Schneider Kreuscnach in particular - but they fetch high prices theses days because of the superior image they give.

I'm a bit surprised at no comments about the DIY zoom lens solution I proposed above - positive or negative Is this just common knowledge or what? I think if you are in a small space and need to make the picture bigger on a low budget ...this is a viable alternative. What's your opinion?

I think your low-cost solution is brilliant! I will be on the hunt for a B&H projector lens myself. At the very least, it is a good temporary solution till a more precision (and hence costly) lens can be acquired.
Thanks for sharing this idea, and for your many other contributions to the forum (PDF's of manuals etc). I always seem to learn something worthwhile from your adventurous efforts!

Thank you Greg. It's good to hear your feedback. I'm going on vacation for a couple of weeks, but when I get back I'll try to put together a lens comparison video. I have a standard Elmo 50mm...an Elmo 35mm...a generic 25mm in 16CL adapter sleeve...and the B&H Zoom lens in the 16CL adapter. Should be interesting

Hi Janice, I didn't know that a Super 8 lens would work with a 16mm projector! Ha, I learn something every day.
My Elmo 16-CL was bought with the original 50mm lens (darn good f1.2 too!! and a strange Elmo "Telecine" 20mm lens that is an unusual f1.4!) The picture is waaaaaaay big from like 8ft lol. The lens is weird because it is very narrow--the stock Elmo mount is exactly the diameter of the whole lens! Looks like a long D battery.
I guess you could option up when you bought an Elmo?
Different approach than Bell and Howell as their 25mm(or is it 28? I'm too lazy to walk down to the basement now..lol) is the same diameter as the 50mm and has a tiny glass inside and is only an f1.9.

8mm projectors were intended for home use, where there is a wide variety of distances and screen sizes, hence the zoom lens.
16mm was primarily intended for classroom use, where the 50mm lens would work almost perfectly from the back of the room to a screen in the front. Zoom lenses, and other focal lengths were available for those who needed them at additional cost.
The 20mm Elmo lens was intended to be used with the Elmo rear screen mirror attachment, for rear screen projection. It will work for front screen projection, but it is touchy to focus.
