Many, many years ago I started out with my first SLR being a Minolta, followed by a couple updated Minoltas until the day I decided I was ready for the then-perceived "gold standard," a Nikon. Bought that N90 and loved it to death, and was a "Nikon Girl" for years and years after that....
Times change, priorities change, needs change.....and a year ago, on the 21st of November 2019, I became no longer a "Nikon Girl" as I traded in my Nikon gear and switched to Sony. This was not an easy decision, not by any means, and I wrestled with it for a very long time before finally arriving at the "decisive moment" and making the change..... Now, a year later in November 2020, I can wholeheartedly say that, yes, for me this was indeed the right choice, the right decision and for the right reasons. I don't exactly call myself a "Sony Girl," but wow, I am sure loving my Sony gear -- it has been and continues to serve me well and brings great joy and often new surprises as I explore my photographic options with the A7R IV and the lenses that I've purchased and used over the last year.
All that said, I would really be very very sad if Nikon does bite the dust.....I have some wonderful memories of experiences with my Nikon cameras and lenses through the years, some nice photos from those times, and, well, basically I learned photography with a Nikon in my hands..... No one can ever take that away, regardless of what happens to the company now..... I know that there are many, many others out there who feel the same.
