I think I'm able to answer the question in your title with a clear: No, I'm not!
Am I obsessed with gear in general though? Yes, I absolutely am... but for the most part not in the way most people here are I guess.
Because while I can rave for hours about the incredible ingenuity some lens designers showed when developing some 50 year old Agfa prototype triplet lens (that's a real example, by the way 😅) I forget about my Sigma Art lens for months. While I can invest a lot of time and effort looking for a way to adapt any insignificant and flawed no-name industrial lens to my bellows system and make it work, I give up on a new lens with too much CAs for my taste almost immediately and return it.
I don't really long for the very best, the latest, the most effective gear there is usually, but I care a lot about optimizing my setup and abilities to use a lens which speaks to me for some reason, to its full ability.
There have been a couple of lenses which really 'inspired' me for lack of a better word, so I certainly have to admit that gear has a significant impact on my photography and motivation in some (weird) way. If you're interested I can show you one or two samples of that.
I have a lot of fun participating in various flickr groups with weekly themes. I find it easy enough to come up with something that satisfies the theme's requirements usually, but challenging enough to get an image I feel good about, which works well as a motivation to keep improving.
