The Bronica GS-1 150mm f4 has excellent glass even into the corners, suitable for landscape, portrait and macro (with close-up lenses or an extension tube). It has half-stop increments down to f22, and uses a 72 mm filter.
The pictures below were all taken with a Zenzanon Bronica PG 150 mm f4 lens on my GS-1.

The lens’s minimum focussing range is 1.5 metres – you need a 0.5 dioptre close-up lens for close portraits (available from manufacturers like Hoya and B&W). There is a rubber lens hood for it which conveniently folds flat, or use the heavier bellows hood.
The above pictures were all taken with a Bronica 150 mm PG lens. The film was scanned with an Epson V700 Photo at 48-bit colour depth using SilverFast SE software. The pictures were then tidied for the web using Photoshop CS3, reducing the image to 24-bit colours.
