Not sure if this has been asked before, just wondering if everyone has his/her own particular favourite lens from your own collection and if so, why? (P.S Not restricted to any one make or brand of lens, can be zoom, prime etc. Just name one!)
I'll start the ball rolling: my current favourite lens is the EF 100mm f2.8 Macro USM. Probably the sharpest lens in my collection, fairly lightweight and compact and capable of churning out incredibly detailed shots. Pricey yes, but I'm slowly learning how to use it to maximise its potential and beginning to see its awesome results. Of course its not without its faults (in AF mode it searches like a blind man wandering around in the dark, rather slow as well). But I love it because of the great results one can get from it.
So what is your favourite lens?
