Having hunted through the archives, I see that there are a few people who can make decent comparisons between the 100 and 180L macro, pros and cons for each. Except if I buy a macro I'll be buying it so if any product work comes up I have the macro option, but mainly as I'm a huge fan of VERY tight crops into model's faces in portraiture. There's loads about the 100 being an excellent portrait lens which is good as it's obviously much cheaper. But my concern and wonder is that for shooting such portraits the extra working distance will be a good thing for the models, as it isn't the easiest thing for them to do when posing with my current 24-70 at closest focal length (just too far way in terms of image crop).
So my questions is has anyone used a 180L macro for portraits? If so what's the verdict? And can anyone offer other options. Moppie on here suggested a pseudo macro zoom, but I think that may be as bad if not worse on the working range from subject....
Cheers for any thoughts.
