Another take on portrait

Shot recently using Canon 1Ds III with EF Macro 100/2.8L IS, the focal length is use here again to portrait the model in a slightly close up framing, but still want to keep the distance from a model slightly longer, with a little compressed perspective.

Taking portrait really has no certain rule, and really it matters with the final use of image or where it is taken and the lighting set up. I remembered years ago when using film, outdoors especially, I used the Contax RTSIII with Carl Zeiss Distagon ME 28/2 - although a wide angle, but because of the ability to shoot close up with very nature perspective control, it was my prime choice of lens back then, but of course, I did not shoot for commercial then.  But will a particular lens gives some inspiration to photographer?  I think it does, at least it is to me. Coming to the age of digital capture, and the relatively high resolution image that the room to crop the image becomes more flexible, and then my choice of focal length became a little narrower, now mostly between 35mm to 100mm for smaller DSLR such as Canon 1Ds III or 5DII, and 80mm to 150mm with medium format, similar to most photographers.  The most different approach is, I almost use prime lens exclusively, not really because I think prime lens final image quality is superior than zoom, it often does, not not all the time.  My favorite zoom lens, Carl Zeiss Vario-Sonnar 45-90 for Contax 645 is perhaps one fo the best lens I ever use, prime or zoom, of any format.  But the preference in using prime is the particular concentration in framing, with a fixed focal length prime, I need to move forward or backward to get the best framing, rather than simply use a zoom lens so my composition seldom change, and result less variety.
