For the first time in 15 years that I have been working with projection lenses, I finally had the opportunity to compare two rare lenses Canon 89mm 3.5” E.F. F1.5 RCA and Snaptar 89mm 3.5” F1.5 RCA I always thought that they were completely identical because they looked the same but after comparing them I realized that they were very different from each other — I had only one day to compare and this is what I managed to do during that day (the size of the front and rear lenses is different because of this Snaptar covers Fuji without vignetting and has a more blurred background) — and also on Canon the aperture when closed gives visible aperture blades while Snaptar when closing the aperture just shows a decreasing circle all the time
