Bell & Howell 154mm Lens
I have an old (believe 1940's) Bell & Howell Type I - 6 inch - f/2.5
E.F.L. 154mm lens. Anyone know what it is or was used for? Thanks, Terry |

Bell & Howell 154mm Lens
If the diaphragm is adjustable it is for taking movies, 16mm.
It would give an image 6 times the normal lens. If the diaphragm is not adjustable it is a projection lens for 16mm movies. Francis in VT Terry wrote: I have an old (believe 1940's) Bell & Howell Type I - 6 inch - f/2.5 E.F.L. 154mm lens. Anyone know what it is or was used for? Thanks, Terry |

Ok - Thanks! Not adjustable. Must be a big projector for this to fit. Terry

Thanks, Terry It is probably a 6" fixed-aperture version of the 7"/2.5 Aero Ektar. B&H made them, and I've seen one other on eBay last year. There was recently a 6"/2.5 fixed-aperture Aero Ektar on eBay, too. Cheers, Dan |

Thanks, Terry If its fixed aperture it could also be from a 35mm slide projector, B&H made them for a while. The barrel will be considerably larger than a 16mm projection lens. 16mm projection lenses also frequently have threads around the barrel for focusing. B&H didn't build lenses so it will have been made for them by someone like Ilex. -- --- Richard Knoppow Los Angeles, CA, USA |
