That’s the mere definition of GAS: buying a lens because we give it some magical atribute that has been missing.
It’s all psychological.
the best example I can give is the following: from january of this year I’ve been relentlessly scanning and printing my lifetime’s work giing back to 1990. All shot on the best and most exotic and rarest glass available. I have carefuly written notes on each negative sleeve (lens, camera, developer, temperature...). I’ve been piling the prints to an insane amount, insane to the point of being unmamageable and I pitty my sons who will have to deal with this when I’m gone. So now you have an idea of the extent.
And one thing strikes me from the very beginning: i could have shot all this work witg any camera and lens. Any! There is not a single print where I say “wow, this lens saved the day”. Sure, I fully appreciate my rolleiflexes, xpans and Leicas with the plethora of collectible lenses. But I could have stuck with my very first minolta XG-9 all the way from 1990 until today (2020), and I’d have the same amount of work piled up. And it would have been the same. The great images would all be there all the same.
in retrospect, all this gear collecting has been, only and totally, an act of indulgence. Nothing more.
Actually, I’d like to go the next 3 years with only one camera and one lens, and lock all the rest of the gear away. This would be brutal in many ways. First, my portfolio would get brutally upgraded, I’m sure. And also brutal because I’d have to realize that all my “beloved” gear was never needed. And that would be a huge slap in my face. “Whaaaat? This summilux is not magical after all?” And “how can I apologize for not using my rolleiflexes, they must have missed me”. Letting go is brutal in a lot of subtle ways.
I’d have no problem documenting India for a whole year with simply a 4x5 pinhole camera. I can imagine all the visual poetry coming out of such an exercise: one-hundred amazing photographs rivaling with the most exquisite paintings. But no, my relentless need for a next magical purchase always gets in the way. It is truly a poisoned state.
