Much food for thought in this thread. Cholentpot in post #6 comes closest to my thoughts about all this, but as befits a good Sagittarian, I also share those many others here.
To me GAS is GAS. Whether it's applied to film or digital gear, doesn't make it any less GASsy.
Over the last decade I've worked through all this in my mind. When digital hit big time in the early 2000s, I still held off for some years, largely because image quality even in Nikons was not up to the minimum standards I held to in my film work. Then Nikon released the D90 in Australia in 2009 and I realised thye time was finally right for me and it was time to bite the bullet and invest in digital. I began pricing Nikon DSLRs, but then, due to an odd series of events I still don't fully understand, I took some trusted advice and went with Canon, first a G10 and then a 450D kit with several lenses.
Unfortunately for me I never really bonded with either camera and I sold the 450D the same year, but held on to the G10 til last year when it finally went to someone on Ebay who wanted one badly and was happy to pay me a little extra dosh for my G10 with only about 2,000 clicks on the counter. In 2010 I finally bought a demo D90 which even with the kit 28-55, has delivered the image quality I want. I've been very happy with it and it's still used, more so by my partner who creates very fine images with it.
In 2012 I went on to FX with a D700 and a pile of D lenses, 20mm to 180mm. I've never been big on zooms, but a 28-85 D I picked up cheaply produces some of my sharpest images, with a little care and paying attention to the straight lines at the 28mm setting.
My twenty or so film cameras (Nikkormats, Contax G1s) sat unloved on various shelves at home for some years until early this year, when I began taking them down one by one, dusting them off, putting in new batteries, stuffing them with films. My reason(s) for returning to analog after almost a decade of digital is/are basically twofold: I have a fridge and a freezer full of film and enlarging papers I want to use up while I can, also the quality of black-and-white images shot on film, especially the mid tones, is such that I prefer film for my 'art' imagery such as landscapes and esoterica, to my DSLRs, which I nowadays mostly use for garden and architectural shooting overseas.
With film I enjoy the total control I have over the process. I'm now retired and I have the time, sufficient income (for the time being) and, fortunately, the good health to indulge myself in slower shooting and processing. In a few more years there will be less money, and I'll have to make some different decisions. But for now, GAS is okay.
With digital I enjoy the convenience, the ability to shoot two, twenty or two hundred images if I want to (most often I indulge in the first two and have never let myself go the way of machine-gunning shots to pick a few out of hundreds, that's just not me), and the joy of being able to see my results immediately if I want. Some pooh-pooh this approach, but it suits me just fine, thanks.
So here I am with five Nikkormats (three ELs and two FT2s, down from seven or eight a few years ago), two Nikon F65s, four Contax G1s (down from six), five Rolleis (added two this year, GAS!), and an assortment of other cameras, mostly 120 6x6 folders. Now and then I part with a camera, often as not when I acquire another that is better than the one I sell or give away. So it is with GAS. After years of just buying, buying, buying, I've finally learned to control the urge to gather in piles. If I had my time again, I would never ever repeat my impulse buying - at least I think I wouldn't. But that's just me. My partner is also an avid photographer and now has an M3 kit we picked up earlier this year. So the camera cycle for this lifetime, now seems complete. Maybe. For now anyway.
Film is now expensive in Australia. My Rolleiflex TLRs mostly sit on the shelf as I find I can no longer justify spending big for a dozen shots on a roll of 120 film when I can get just as good results with my Nikon D700 and a fixed D lens.Yet I still pick up film cameras.this year, a Rollei 2.8E2 kit, a Leica M3 kit, and recently, a beaut Rolleicord Vb on Ebay auction from with a starting price of A$90 - I was the only bidder. So yes, GAS.
So what do I do with it? Well, I use it. Sort of. I try to shoot one roll every year in every camera I own. I did in 2015, also last year. This year, well, you know. It has been a cold, cold winter down here and all that...
My stepkids in Malaysia and are keen to get their hot little hands on my film cameras. Unfortunately for them, their approach to date has been "how much do you think it's worth?" which tells me a lot. I mean, I can sell it all myself and enjoy the returns. For now, I hang on to it.
Time passes, things change. GAS endures... not forever, but it lasts. I prefer to embrace it and enjoy it.
