Hello, please can anyone advise the cost of a mint condition, boxed, elmo f1.4 25-50 lens. I have been offered one, how much do these lenses sell for. This lens comes from a widow, i dont wish to short change her. Thanks for any advice

Andy,
I am lucky to have the Elmo 25-50mm lens, it is actually an f1.2 lens. This is a superb all glass lens and is quite heavy. It is the lens you must have for auditorium use. I believe John Clancy uses this lens at the BFCC. I paid $300.00 for mine on ebay.

Actually Elmo did come out with a 1.4 long throw lens before they had the 1.2. The 1.2 though is probably one of the best lenses every made for the Elmo line. It is in my opinion better than the 1.0 in terms of sharpness-

Paul,
Congratulations on tracking down the 1.2 version. I've heard that these are exceptionally rare, and your post represents the first evidence I've come across of someone actually owning one!

I use to have one but I sold it along with my Xenon GS to the notorious Frank Adams!
Then he sold the projector to Alan Gouger of this forum with the 1.2 and so now.. Alan Gouger has it. [Smile]

Also Phil's Vintage has one with a 1.0 to be sold as a set with 2x GS1200's here:

The lens is kind of rare..unless you know where to look! [Smile]

I've got a pair of 1.4. One came with one of my GS and I bought the other from one of this forum members for 80GBP.
I saw a 1.2 for 250 euros recently, so I guess Paul's price is right.

I have a 1.2 25-50mm and I'm in total agreement with Rik. It is the sharpest super 8mm lens I've seen. One problem: I'd need to make some holes in a few walls in order to get the projector far enough away from the screen to get a decent size picture!

Andy,

Sorry I can't quote you a price as the lens came with the projector.

Hi, thanks for the replies, i will be bringing the lens along to Ealing as i have no requirement for it. So if anyone wants it for a few pence!!!, let me know.

Posted by Kevin Faulkner (Member # 6) on May 09, 2006, 05:26 PM:

Just a few pence [Eek!]

I'll make it 10 [Big Grin]

Is that 10 pence or 10 squid, Kevin [Big Grin]

Andy, I've had Robert Tucker in touch with me recently after just that very lens. Assuming it is a 1.2 or 1.4 can you reserve it for him as he's coming to Ealing especially to look for one.

Ive got a 1.2 long throw lens but never used it. Can someone tell me the minimum and maximum distance you can use it for and still focus.

Just curious as lens sizes have always baffled me as to the size of the picture, distance etc.

Depends on what gauge you are using it with.
The picture width is inversely proportional to th focal length i.e. the picture will be half as wide at 50mm as it is at 25mm.

Thanks Martin. I would be using it for Super 8 with the GS1200.

A 25 mm lens will give a picture 1.2 m wide at a throw of 6m with Super 8 film.
Double the throw, you double the width. Double the focal length, you halve the width.
All quoted figures are a close approximation as different machines may have slightly different apertures, but they are close enough for all practical purposes.
