I've been out of the large format world for a few years now, but am brushing up and looking at purchasing some new LF gear. I've been reading up on lenses in particular and trying to understand what kind of lens would best suit my tastes. The options are staggering. I've attached a sample of what I'm looking for. This is an image from Quinn Jacobson's site. I understand that it's wet plate, brass lens, etc. What I'm looking for is a similarly shallow depth of field and similar subject framing at normal working distance to subject. I'd like this in a modern lens with a shutter. I've already looked into having a brass lens mounted into a shutter and that's starting to seem like an option that isn't likely to be a good fit for me. My preference is to go with 4x5, but I'm open to an 8x10.
So if I wanted a head and shoulders portrait with very shallow depth of field, at a camera to subject distance of 5 or 6 feet, what would you recommend?
