I picked up an adapter on eBay, to use my old FD mount canon lenses on my current EF-S mount camera. It’s not perfect… it messes with the light and focus. But I did make sure to get one with the lens to compensate as much as possible. It also requires manual focus and aperture. I popped off a couple test shots while Abbey scowled at me. And I got a few with the modern version of the same lens, for comparison. Need to work on my focusing. But it will be fun to use the old glass, sometimes.
