A nice looking Kodak M100 has popped up on ebay.

The M100 is a very nice, professional quality, machine. You could call it Kodak's GS1200! Built to 16mm quality, and notable for its 2000ft spool capacity, 150 watt halogen lamp with high and low settings, and most of all its truly superb f1.0 non-zoom Ektar lens. I had one of these machines a while back, and the only complaint I had was the poor quality sound (at least on my particular machine). The amplifier is a hybrid design - some valves along with transistors. I dumped the projector, but kept that superb lens, which I had machined down to fit my Eumigs. I can say that it truly transforms the picture quality on those machines - needle sharp flat field with stunning contrast. You cannot use this lens on Elmo's because the back focal length is so small, and the Elmos do not permit you to push the lens in far enough.
A great projector, undoubtedly Kodaks best ever super 8mm machine.

The lens sounds good but the area around the sprockets etc doesn`t look too inspiring!!!!!! for safe film transport.
Is it the valve base 150 watt, they can cook the film and cause frame lifting at 18FPS.
Best Mark.

Hi Rik,
Attached is a photo of the modified Ektar Lens. I re-checked the dimensions and the outer diameter is machined down to 32 mm along a length of about 53mm from the small end.
I had this work done at the machine shop where I worked. It is a first class shop and they only do government contract work. Unfortunately I can no longer 'bootleg' work into that shop, so there is no way I can get them to do it for you. I would think if you can locate a reputable shop in your area you need to meet with their best lathe man and sit down and explain exactly what you want done. Show him the attached photo of 'the finished product'. Looking closely at my lens, it is possible that the 'snout' end of the lens was in fact machined off (I can't be sure of this), then modified or remade, and reattached by epoxy bonding. One thing I do know is that none of the lenses came out during this operation (do NOT let that happen!), so re-attaching the snout would in no way affect the quality of the lens, you just need something to grab hold of to adjust the focus in the projector!
Hope this helps a little. Good luck and keep us posted of your progress. One thing for sure, if you can get this lens into the Eumig you will see a huge jump in picture quality.
