One of the cooler things about owning a camera with a legacy lens system is that you can use their lenses with old school film cameras loaded with fresh film. That typically goes for lots of new lens options on the market. To be clear, this means that Canon EF, Nikon F, Pentax K, Leica M, and Sony/Minolta A mount lenses can all work seamlessly on your film cameras and your digital cameras without the need for an adapter. In fact, for a really long time I’ve used the Canon EOS Elan 7 as a backup camera body of sorts.
So what happens when you use new lenses with film? Those of you who grew up with film may say nothing special. But for those of us who started in digital, we say differently.
