I am interested to know what lens other 16mm users use. With my living room about 13 or 14 feet, the standard 2" lens is too small; I recently got a 1" wide barrel lens, which will fill my 50" screen. The narrow barrel F1.9 lens can be picked up with not too much difficulty, but this is the first time I have seen an F1.4 wide barrel lens, so I wondered what others use?. The Bell & Howell zoom lens is only the equivalent of a 1 and half inch lens; not suitable for me, but perhaps if you live in an older house, some of which have a 20ft living room, it might be OK.
