Steve, there are two 35mm lens adapters for this camera that I know of, one that Sony sells which will directly connect Sony 35mm lenses to the camera, and then there’s a guy in the UK that sells an adapter for Nikon 35mm lenses. I have a Z7U, although I have not tried either of the 35mm lens adapters. The Z7U uses the three-prong bayonet lenses as stock. I am able to directly plug in my Fujinon lens from my JVC GY-HD100 without modification. Definitely gives you a lot of flexibility. Although the adapters are fairly expensive for just a little piece of metal. The Sony adapter runs for upwards of $600 if I remember correctly, and the Nikon adapter comes in around $400 based on the conversion rate of pounds sterling. Not sure if you’re looking at Canon 35mm SLR lenses, or Canon video camera lenses. Either way, I hope this sheds more light.
