Exactly! I don't think I'm suddenly a better photographer because I went with Sony after having used Nikon for many, many years.... The difference is more about the fact that this time around over the past year I've purchased native lenses offered by Sony that I knew from my past experience were ones I'd actually use a lot (a couple of macros, a couple of fast lenses, etc., in the same or nearly the same focal ranges as previously), plus a couple of lenses which have expanded my horizons significantly, going beyond the longest lengths I'd had in Nikon, which had been a 300mm prime lens and an 80-400mm zoom.
After having used my Sony RX10 M4 for a while, since 2018, a bridge camera with a rather amazing zoom range from 24mm - 600mm (equivalent) on a 1" sensor, I was spoiled. I wanted that long reach right out to 600mm again, this time in full frame. As it happens, Sony does provide not only very expen$ive prime lenses in the longer focal lengths but also a couple of fairly affordable zoom lenses (100-400mm, 200-600mm) -- and the latter have suited my needs and desires perfectly. In some situations I am now able to capture images that I was unable to get before.
That in and of itself, though, doesn't make one a better photographer, though, but it is a factor, especially with new technology in the newer camera bodies and lenses. Current lenses are much more optically refined, sharper, and for the most part free of some issues which plagued lenses of the past. They make it easier, indeed, to get the kind of images one wants. In addition, the editing software programs that most of us use for post-processing our images in the computer have improved quite a bit, too, making it again easier for me to get better results than I got several years ago.....and that, too, is satisfying. I may not be that much better a photographer than I was a year, two years, five years, or ten years ago, but I do find the process a bit easier and still a lot of fun!
