I don't know that much of this is on record, but I bet that if you could know what lenses many published, respected and even revered photographers owned / carried / used, you'd find that most were lens-light rather than lens-heavy. Being image-hungry is one thing, whilst being equipment-hungry is probably a disease. Ask HCB, McCullin, Koudelka, Bailey - pick names out of a hat.
A lot of photographic images especially in the amateur and stock photography realms look as if the lens took the photo, rather than the photographer. Look, wide angle shot! Look, telephoto shot! Ha! Clever stuff! Boring.
If I was to spend a year or the rest of my life with a single lens, one about 75mm would be right (now there's a gap in the market). An 85 would do. Or a 50. I grant that birders and 'insecteers' have special needs (!). And some people have a wide angle mentality, which can be respected if the results ring true but is often repetitively formulaic.
So I need ONE lens, but happen to own three, and normally carry just two of them. I should add that none of them ZOOM, and neither do they AUTOFOCUS.
Back to the thread? I never left it.
