Nikon D300, Micro-Nikkor 55mm f3.5 AI
So the D90 is gone, I just never got along with it and there's little point in owning a camera that you don't want to shoot. Replaced it with a D300 for a shockingly low cost (seriously measured in beer).
And I'm reminded exactly why I shouldn't have sold my D300 8 years ago. Yeah, it's a brick, but it's a very, very good camera that just happens to be heavy. As it has an AI tab, I can now shoot with my AI lenses, especially the 55 Micro-Nikkor, which is an utter gem, and my old faithful 300/4.5 AI'd, that I've owned for years.
Selling my D300 has long been the point where I really started chasing the dragon with regards to my gear. I went through a bunch of gear before then, but always had real performance issues with it until I got the D300. After that it was a mix of performance issues and the grass is greener. There's no reason I couldn't have stayed with the D300 system, the A700 system, the D7100 system or the D700 system I've had. The mirrorless stuff worked less well for me, but even then the E-M5, E-M1 or GX7 all were more than enough for what I needed.
So I'm back where I began, and I hope to stay there for a while. I need a lens (UWA) or two to round things out, but I largely have what I need and don't really see a reason to change.
