Premium Member Simon Wyss Posted August 14, 2017 Premium Member Share Posted August 14, 2017 Hello, everyone! Announcing professional technical service, repair, and maintenance of Bell & Howell 8mm film cameras Early Filmo 8s have the spigot or clip-on type lens mount. Although almost a thing of the past these can be disassembled, cleaned, checked, dressed, lubricated, reassembled, and adjusted like anything else. Some bayonet mount lenses are more desirable than others, I can give advice. Adapters are around for the use of D-mount or C-mount thread optics. The lens mounting threads with turret models is no D mount but a slightly larger one plus flange focal distance is shorter. There are adapters to bridge this gap, too. Fall 1951 one-eye Filmo 8s got the D mount. From January 1st, 1957 on only D-mount models were sold. All-metal made Filmo Eights can have a bright future when properly maintained. I know about the two or three weakish points in the design and have remedies. What regards the gear train these little cameras are champions! Double-Eight film is available. Perforators are around for continued conversion of unperforated 16mm stocks. Nothing against the other brands—Bell & Howell Filmo 8s are unique in perfection. I take models 127, 134, GB 605, lenses, and accessories. Due to the age and varying conditions I am not able to standardize a price. As a rule of thumb please acknowledge a minimum of two work hours. I grant a two years warranty on my work. Film-Mechanik Simon Wyss Rixheimer St. 35 4055 Basel Switzerland simon-wyss@gmx.net Link to comment Share on other sites More sharing options...
Stefan Fischer Posted February 21, 2018 Share Posted February 21, 2018 Hi Simon Very good infos above. I repaired and serviced many Eyemo and 16mm Filmos. If the little BH 8s are as solid and well made as their big brothers, this could be a perfect 8mm camera. Im going to buy one on eBay. But not sure which one to choose. Can you give me some advice please? Need a simple one, no turret but 24 FPS and d- mount. Thank you Stefan Link to comment Share on other sites More sharing options...
Premium Member Simon Wyss Posted February 22, 2018 Author Premium Member Share Posted February 22, 2018 The 8s are very well made. Adjustable bearings, adjustable governor brake, a cleverly made film advance shuttle, active lateral film guidance, take-up friction that can be oiled. I think it’s you who knows best what to choose. 24 fps you have with all models, the regular ones have the 8 to 32 speed range, called Companion. Sportsters run from 16 to 64. Caution: early Filmo 8s don’t have a single frame function. If you want a critical focuser you pick the turret version. Here the English made with D mounts are preferable. The American Aristocrat has different threads (also very short) and FFD. With an adapter, however, you can use those lenses on a D-mount camera. Elgeet made a range of adapters.

Robert Randall Posted January 16, 2020 Share Posted January 16, 2020 I’ve been going crazy adapting all sorts of old cine lenses. I recently got a bell and Howell 8 mm magazine camera with a lens that slightly larger than D mount. What is the adapter you’re talking about to make these work?

Premium Member Simon Wyss Posted January 16, 2020 Author Premium Member Share Posted January 16, 2020 The adapter D-mount to 134-Turret is Elgeet nr. 384, like here. Elgeet 386 lets you use C-mount lenses with clip-on Eights. Elgeet 389 serves to put C-mount lenses on a 134 T. 1 Link to comment Share on other sites More sharing options...
Robert Randall Posted January 16, 2020 Share Posted January 16, 2020 (edited) Thank you! Forgive my ignorance and lack of specificity. I’m trying to use this lens on my m43 camera for which I have both C and D adapters. This Here They’ve listed it as an rms mount. Is that correct?

Premium Member Simon Wyss Posted January 16, 2020 Author Premium Member Share Posted January 16, 2020 (edited) Oh, no, that lens lacks an intermediary ring from a special thread* to the 134 turret thread. RMS is metric and Taylor, Taylor & Hobson or the American manufacturer wouldn’t use metric threads. Comat and Super Comat lenses are Cookes which leaves me a bit at loss about the Made in U. S. A. It is a normal lens for 8mm film cameras. May have been Wollensak to sub-treat this. _______________________ * 95/128" or 18,85 mm, 40 t. p. i., 60 degrees flank angle Edited January 16, 2020 by Simon Wyss Thread specifications added 1 Link to comment Share on other sites More sharing options...
Robert Randall Posted January 17, 2020 Share Posted January 17, 2020 Hmmm interesting. So i guess I'm going to have trouble adapting these lenses without 3d printing some special adapter or rigging one up somehow. If only I could adapt them to C or D mount I'd be home free. I got a few of these lenses with a couple Bell and Howell camera's I picked up cheap, but I suppose they must head back from whence they came.

Premium Member Simon Wyss Posted January 17, 2020 Author Premium Member Share Posted January 17, 2020 I have seen Angénieux lenses bearing that ring, Wollensak, and TTH. For your consideration, the Comat is a dialytic four-glass design, the Super Comat has five elements. In a way, big and heavy lenses contradict the Filmo-8 concept.
