<p>For the kind of work you are talking about, Dave, I'd avoid field and press cameras like the plague. And I do love field and press cameras, but not for head-and-shoulders work. But a monorail with a 250 or 300 (although I've "gotten by" with a 190 and 210) is what you need, as well as a "set" that includes chair, stool, and/or table to facilitate posing. For me the biggest concern is the sharpness of the lens... most are too sharp. A dedicated soft-focus lens is really worthwhile but some of the SF filters work good enough. Older lens designs like Tessar and even Rapid Rectilinears are useful but even they can be "too sharp". Iv'e successfully shot most of my portrait work in natural light (including indoors) but I can see how strobes (or even hot lights) would be a big benefit. Not to dissuade you in any way, but if you can't do it in MF the chances of doing it in LF is slim.</p>
