[Do you only use the 35 as your widest lens scalesusa? MY concern is that the 35 wont be wide enough but then I also think that dropping a lot of money on the 25 this early doesnt make the most sense for me when in reality it might just be used for a few shots of interiors where DOF wont be as critical to me as I'll want most of the scene in focus so paying for that low aperture might not be worth it. If you had to choose between your 85 and your 35, if you only had the 50 f1.4 and the 135 f2 which would it be?
I have a lot of primes and zooms. I tend to favor the ones listed above most of the time.
Canon 15mm fisheye
Tokina 17mm f/3.5
Canon 24-105mm L
Canon 35mm L
Canon 50mm f/1.4
Canon 70-200mm f/4 IS
Canon 85mm f/1.8
Canon 100mm L
Canon 100-400mm L
Canon 135mm L
I also have a Canon 28mm f/2.8, Canon 22-55mm that I do not use, and will probably sell some day. I've owned a lot more Canon lenses, I buy and sell them pretty often, and keep the ones that work for me. I don't lose money, I make sure I can sell a lens for what I paid for it, or I pass it up.
I also have Canon Tc's, and extension rings, reverse lens adapter, and a lot of adapters for other lens makes to EOS. I have lots of old film cameras from almost every manufacturer, bought for the lenses. Even a Hasselblad that I bought used three weeks ago.
i'm retired and go to a lot of garage sales as well as having some great software that does a Craigslist search over several cities within a few hundred miles, so I find the bargains on craigslist right away. I can spot a Craigslist scammer immediately, after using craigslist a while, they stand out clearly. I only buy in person.
