I did not and do not consider the Nikon gear that I recently traded in or the new Sony gear that I acquired during that transaction/process as being "investments." Sure, the money that I spent though the years in which I had accumulated the Nikon gear was much more than what was deemed appropriate at the time of trade-in, and I was fully prepared for that. I used and loved my Nikon gear for many years. It served me well. So, yes, the camera bodies and lenses are and have been in the past (Nikon gear) very wonderful tools that I have enjoyed using for hours on end and which gave me much, much pleasure, and I am now (with Sony) currently enjoying again using (newer) gear for hours on end.....deriving much emotional satisfaction, finding and exploring new challenges and enjoying figuring them out -- in short, just plain having fun..... Never mind the monetary aspect of this, what the gear cost. It wasn't meant to be an investment in the first place. Isn't that sheer emotional pleasure I am getting and have in the past gotten from using my photographic gear worth something, too?
