5cm f/1.5 Tokyo Optical Co. Simlar

5cm f/1.5 Tokyo Optical Co. Simlar





Filter size: 40mm (!) I am going to try to get a 40mm - 46mm adapter from HeavyStar.  It is possible some samples of the Simlar have other filter sizes.
Close focus: 3.5 feet
Aperture range: f/1.5 - f/16 (no detents)
Aperture blades: 12 rounded
Depth of field scale for f/1.5 - f/16, IR index.

Comments: The Simlar, made by the predecessor to TopCon and sold on Leotax cameras, seems to be a rare lens.  People put outrageous prices on them on E-Bay, and there isn not much information about them out there.  Of course, Google helpfully auto-corrects "Simlar" to "Similar".  My sample has an oily aperture and two scratches on the front element, but is otherwise in good shape.  The build quality and chrome-covered brass looks a lot like the old Nikkors and Canon Serenars.  I love the image quality: it runs circles around my Summitar.  Generally I find the lens to be sharp with a lovely look.

I use a plastic slip-on 42mm cap.
