If you really wanted to use a leaf shutter lens on a digital SLR, the price point isn't quite so high. I've adapted a Mamiya 645 leaf shutter lens to Nikon full frame using a cheap third party adapter. A small selection of leaf shutter lenses were made for the 645 (standard lenses used the body's focal plane shutter with a sync of 1/60s). The 55 f2.8, 70 f2.8 and 150mm f3.8 were all made with an integrated shutter for full flash sync at up to 1/500s. I see the 70mm selling for around $115 these days. That said, they're a real pain the neck to actually use, since you have to compose and focus, cock the shutter on the lens, release the shutter on the camera body (bulb mode or a long exposure), then fire the shutter on the lens using a cable release, then after the body is finished, open up the lens again.
