I'm only 45 and and admitted GAS infected sort. In the past year for whatever reason I have been reflecting and paring down my considerable stash. Perhaps it is just that I know when I die my wife would get ripped off selling the stuff. I make 90% of my living with this. D700, 105 f1.8 AIS and 18-35mm AF Nikkors. I shoot the other 5% with everything from a fisheye to a 300mm f2.8 My Hasselblad and Leaf Aptus do the other 5%. My Sinar System has not been used to make a dime in 2 years. SOOO ... I sold all my Rangefinder gear last year except a Fed 3 and Leica 2.0 , 50mm. I sold my Shen Hao 4x5 and lenses. Contemplating selling the whole Sinar kit.... just what if I am asked to photograph something great one day!?! Thought about selling the Hasselbald 50mm FLE will keep the 80 and 150 till death or at least till starvation. I bought a Toyo 5x7 half plate camera as a back up for the Sinar's possible sale. Shall I keep the F100 or the FE2? Nikonos kit stays.... even thought I am a professed SLR shooter. Keeping the Anthony 8x10 and Vitax.... I have big plans for it. I have a collection of Ikons and TLRs that will go too.
