The Canon 7 And The 'Dream' Lens Would You Believe f/0.95?

摘要

In 1961, when the Canon 7 was introduced, its revolutionary new standard lens was advertised as being four times brighter than the human eye. How such a thing could be measured is somewhat questionable, but what is undoubtedly true is that the lens was a lot bigger, and with a much wider aperture, than had hitherto been seen on a 35mm camera. This was the now legendary 50mm f/0.95, a bunch of optics that became known as the Canon Dream Lens. It was a huge chunk of glass whose lens cap had a diameter of 75mm and, at a time when most rangefinder camera standard Lenses had filter threads of perhaps 40-50mm, this one boasted a whopping 72mm.
