I'm as guilty as any other compulsive camera buyer. I wax on about how one camera feels "just right" in my hands or how another camera gives me "amazing" low noise, high resolution files. I spent enormous amounts of money buying lenses that more or less duplicate most aspects of those I already own but (supposedly) add some sort of quasi-emotional nuance to the final images that I sometimes delude myself into believing I can see on my monitor. When I bought my "serious" Sony work system I made what I thought were very smart purchases. I bought the A7rii, the A7ii (as back-up) the 24-70mm f4.0, the 70-200mm f4.0G and a few specialty lenses. Then I spent most of the year gilding those lilies by adding more and more silly lens purchases; all of which I can easily justify, if pressed by more strategic thinkers. Of course I needed the Rokinon 100mm macro for product work and the 135mm f2.0 for those times when I just had to see what long lenses with enormous apertures would do for my art....
And then there was the flurry of Contax/Zeiss/Yashica lenses that I couldn't live without because
