What attracted me to Nikon initially was the Christmas present my wife got me in 2007, a Nikon D40x with the kit 18-55 & 55-200.  The body is still going strong, but the lenses died years ago.  I have always enjoyed the pictures I've been able to capture with a Nikon.  I like the menus, they have a familiarity I appreciate.  I thought a step up to a D5300 would satisfy my needs a few years ago.  Even though it was a big step up from the D40x, it still left me wanting.  I wanted something I didn't have to worry about in the rain, something I could take with me everywhere without having to baby it too much, something that had a similar menu to other cameras so I am not learning with each new body, (the menu on the D5300 was awful).  I am not hard on my gear, I just hate the idea of dropping all that dough to be lost to a rainstorm I didn't plan for or jostled around too much and not work anymore.  So I got a used D800 off eBay and quickly found out its a horrible idea to buy a camera from just anybody off the internet.  The body came cracked and the seller tried saying it wasn't even the same body he sent me, (lies).  Anyways, I decided to fix the D800 as best I could, (pretty darn good job if I do say so myself) give it a run through the spa with a pro sensor cleaning and a once over and then went out and bought a D7500 to get that true protection from the elements I needed.  I hit the sweet spot with that camera.  It just about ticks all the boxes for me.  I have a bunch of lenses for Nikon I have acquired over the years, mostly FX and a few DX lenses.  Now, I feel like I am all in despite the fact I have 0/3 of the "Holy Trinity".  I guess what draws me now is what is comfortable.  I have all these lenses that work with whatever Nikon camera I get.  I might loose a couple if I jump into a Z mount, but the thought of scrapping all the lenses and bodies I have acquired and starting from scratch seems too daunting of a task for what I use my cameras for.  Maybe if I was a pro, I would be more concerned about having the newest and the best.  For me and my needs, I like a good full frame camera and a good crop camera that I can interchange the lenses as I want to and the menus and buttons are very similar so I don't get lost using one body or the other.  Even though some of the fancy newer cameras have drawn my eye, I have a huge love for Nikon because that is what I have always used and I don't see a need right now to learn a whole new system.  Will I feel the same way after Nikon's money concerns turn into money problems?  Probably.  Sorry Nikon, I'm definitely a stage 4 clinger.  Don't try to go anywhere, Nikon because if you do, I will find you!  Plus, maybe then I would be able to afford a D850 and a D500! (not holding my breath though)
