G'Day Nick, and Simon, and all:
I have the "boring three", 50/80/150, and although there is little praise for the 80 in this forum (mine is the CFE - not that it matters I think), I actually find that I like the 80 more and more. The 50FLE is a great lens and of my three, it tends to stay on the body when the set-up gets put into the case, so it is often the 'default lens', if you get my drift. Of my three, the 150 is least favoured, although I have to say that it does exactly what I want for portraits.
However, as one of my mentors once told me when all I had was a lovely Rollei TLR, "for telephoto, walk towards, for wide angle, walk away from". I know this is not always practical, but to be truthful, when I get in a certain 'zone' making pictures, I don't want any distractions. Body, lens, tripod, finder, shade, spotmeter, three backs. Create. Go home. All this other technical stuff is certainly good to exercise the brain, and interesting, but in the 'heat' of the moment, it comes down to exposing film (or a sensor) to light, to get the image you have already seen in your brain. I have too often been asked "that's a great picture...what camera do you use?" (That's a great book you wrote, what word processor did you use.)
I have been making pictures for a little over 50 years, and I have had all the 'gotta haves'. 35mm camera fisheye out to 500 teles, Leica RF WA to Tele, TLRs, Speed Graphics !!, Linhof, 6x7 etc. etc. But when I get too equipment oriented, I tend to put it all away and go into 'hibernation'. Eventually, out comes one body, and a lens, and I'm back in business! I guess I'm more a draftsman than a photographer ... a sketchpad and a pencil.
So, after this ramble, I CONCLUDE that I have never used a bad Hasselblad lens - including the 180 I tried before I paid much less for the 150, and the silver 40 which weighed 100 pounds that I had on long term loan, and the 140-280 Variogon my friend has and never uses (what a lump of glass!). They all seem good to me. As Marc is often wont to say: just make pictures. Get your mojo going. Please yourself first. Let the cards fall where hey may. (Except all pros, who must please the client first
)
Cheers,
Colin
