<p>Hi Ben, I have the Hasselblad bellows, and while you can fit all the lenses on it, there is a special bellows lens....the 135 S-Planar that does close up to infinity.<br>
Really awkward to use though, and you really need a tripod. Mine has a double cable release so you can pre fire the lens before the camera shutter, then another press to fire the lens shutter...see, not for hand holding!<br>
Mostly these days I use the 120mm S -Planar, which has normal focusing and operates like the rest of the lenses, albeit going nowhere near as close....you need extension tubes for that.<br>
For your type of photography, I would imagine that the best lens is the standard 80mm Planar, or maybe the 65mm Distagon. For portraits there is no better lens than the 150mm Sonnar, but slower to use.</p>
