Let's say for a moment that Lens Acquisition Syndrome has been outlawed and we are all forced to reduce our collections down to a single lens. What one lens would you want?
For me, it would be my 100mm 2.8 macro lens. With that one lens I could do virtually every type of photography I enjoy - macro, food, product, portrait and landscape (yes I use it quite a bit for landscape images). I love that lens, so it would be a pretty easy decision for me to make.
But that's just me. I'm curious to know what other people would choose.
