I'm through buying photographic equipment for the forseeable future.
Same here. The amount of money I have (foolishly? needlessly? recklessly?) squandered on camera equipment over the past four decades, endlessly chasing after minor improvements in image quality, is truly too scary to contemplate. Mind you, all of these so-called improvements struck me as being huge improvements at the time: i.e., if I could see a difference, then by definition it had to be a significant one! But history has since provided me with the perspective I clearly lacked in those days and I have (belatedly) come to realize the fundamental error inherent in my prior way of thinking.
Whenever I look at photographic forums these days - increasingly seldom - my heart sinks at the endless proliferation of hardware, much of which outperforms everything I own. There's a terrible futility to it all, this continual raising of the technical bar. Maybe one day there will be a 4/3 body that seems utterly compelling, but..
I've been photographing happily (and exclusively!) with a pair of used Sony RX1s that I bought in March and April of this year. While they're not perfect by any stretch of the imagination, despite my decidedly outlier needs (I photograph mostly at night, among other things) they're not only getting the job done for me, but doing it quite well. You regret buying your Nikon gear? I'll see you that and raise you a medium-format digital outfit that I haven't used in nearly three years that is collecting dust almost as quickly as it depreciates, along with a pair of Fuji bodies and several lenses, a half-dozen m4/3 and 4/3 bodies and several lenses, and also a half-dozen medium- and large-format cameras that I never use but still own only because they're worth so little these days that selling them hasn't seemed worth the effort.
Well, I'm finally done: one camera, one lens (well, actually two lenses, because I also use a wide-angle converter with my RX1s occasionally) and for the next few years, at least, I plan to focus my attention on my compositions and technique instead of continuously researching my next upgrade and then working overtime to fund its purchase.
Unless Sony eventually releases an RX2, of course...
