Well it is not an Eiki lens. It is some other make that has been 'sleeved' to fit the Eiki lens barrel, but if it produces the sharp image with no vignetting at the corners of the picture, as stated in the advert, then it is an asset for short throw projection.

It's probably a 1950s Bell & Howell lens sleeved up for an Eiki. Looks OK but its an F1.6 so if you're used to an F1.2 the picture will be less bright especially with a bigger picture.

Bell & Howell did make a 1" lens for the earlier "blimp" case projectors but the lens in the pic looks more like a lens for an 8mm projector.
Very few 16mm owners would have felt the need for a 1" lens so probably few were ever sold.

Thank U all so much for your input n I have another question, well, two actually:

1) Is it a good deal for the price?

2) I was under the impression 1 inch was the brightest when I bought this lens. Is it the sharpest instead :/? Could someone please elaborate [Smile]

? Thanks again and you all have yourselves a great weekend [Smile]

The price is just perhaps a little over value.

The 1" is its focal length, it bears no indication of the light passed through it, that is governed by its aperture. Most modern lenses are F1.2 which will pass more light than a F1.6, probably over twice the amount.

As this might be a lens for an 8mm projector it could pass even less light due to its physical diameter being considerably less than a basic lens for a 16mm projector

I`d say it looks ok for the price.

Omer does a very poor Increlite 8mm one sleeved but this one looks 16mm to me.

1.6 is`nt too bad.

If I am not mistaking, it is a 25 mm lense. As far as I know, the lens that will give you the bigger picture with an Eiki projector is 12,5 mm, but this lens is rare and expensive. The price you paid for your 25 mm seems correct to me. 1.6 is not what gives you the more light but keep in mind that a non zoom lens gives you more light than a zoom one that has the same or a better number (like 1.3 for example), so the impression you will have will depend on what you are using at the present. Don't forget a 16 mm projector usually has a 200 or a 250 watts bulb. I personnaly think it is more than enough for a home use.

Dominique
The standard lens on a 16mm Eiki/Elf projector is a 2" which is 50mm. The advertised lens is a 1" inch, or as you say, a 25mm.
This will give a bigger picture.
If a sleeved lens of 1/2" (12.5mm) could be found it would give a massive picture on a 16mm projector.

That's correct, Maurice, I should have started by saying that 25 mm is a lens that gives a bigger picture than the standard 50 mm. I don't look often for lenses, but I saw only two 12,5 mm these last months. They were both expensive (I intentionnaly don't mention the price to avoid prices increases effect).

From my experiments it's worth noting two things about very short focal length lenses on 16mm projectors not recommended by the original projector manufacturer - focus and frame coverage. 8mm projection lenses need to approach the gate very closely. If the mount prevents the lens getting close to the gate then the projected image will not be sharply focussed. Also most 8mm lenses do not cover the 16mm gate properly and show a darkening away from the centre towards the corners. This was a problem with the Bolex Hi Fi 17-34mm lens I tried recently. It had a 42mm barrel so should worked in my Rank Aldis/Bauer projector. Alas it did not. The only way is to try it and see.

Eiki and Elmo do a 12.5mm lens that is amazing.

The Elmo I am selling ( sorry fr the plug ) looks better than some 25mm ones I`ve seen.

Hello,

I have been using this lens for two weeks now n must say it's just PERFECT [Smile]

!!! Seems almost as sharp as my standard f/ 1.2, and still, quite the short throw lens. I highly recommend Omer to anyone on the market for an excellent short throw lens. All my "What 16mm movies did you watch lately?" screen shots are on this lens.
