The Elmo long throw lenses were both 25-50mm focal length. The first one had an f/1.4 aperture and the later one an f/1.2.

For me the Sankyo Hi Pro 1.1 15-30 zoom and the Schneider Kreuscnach 1.1
11-30 zoom. also the BolexPaillard 1.3 zoom. Like others I have limited throw so I prefer zoom lenses.

Joe, From memory the Elmo f1.0 was just at the end of its limit from projector to screen distance, I swopped it out for the 1.2 long throw, which was as sharp and just as bright, but with about mid range on the zoom effect.

I found that a less than perfect 1.0 Elmo lens was not in focus completely across the frame. And it seemed that I had to constantly "ride" the focus as the lesser quality ones seemed to slip. I checked the machine and adjusted it and found the problem was the lens. Then I purchased a New Old Stock 1.0 in the box and it is perfect. Edge to edge sharpness and no need to refocus. Fantastic performer. I would love to try and mount the 1.0 on the Beaulieu but the lens would have to be modified or the projector and I want to keep both stock.
The 1.1 Schneider on the Beaulieu is also technically a perfect lens for that machine. Edge to edge sharpness and easy to focus. Also to my eyes almost as bright or maybe just as bright as the 1.0 Elmo lens.
When I use the Ektar lens it really is stunning. Super super sharp with shimmering grain. At a 20 ft throw the image is about 2 feet wide and 2 feet tall. Beautiful, beautiful...tiny image. [Frown]

I always fancied the 1.0 however, and as mentioned on here before, the 1.1 lens is a good bright lens and also has a good sharp image, the 1.0 lens has better light output but the 1.1 is defiantly sharper and easier to focus. This was also pointed in a few magazines in years gone by. My only problem with the Elmo Lens is the fact they seem to suffer with a little lens mould on the inner front. Mine has this problem & although the image is perfectly OK I feel I am missing out on its light output.
Can anyone recommend a good photography shop that is able to take these apart and clean them?

Hi Tom, thought I read somewhere maybe here on the forum you can place the lens in direct sunlight for a time, and the sun uv rays destroy the fungus spores on the lens.
