Respectfully, it may have the same number of points, but the system is not the same.
The D7200 and the D7500 share the same Multi-CAM system, Version II. D7100 has version I.
The Expeed engine is also upgraded on the D7500
The Expeed 5 engine is a big step up from the Expeed 4 engine in performance, as I can testify
from the D7200 to D7500 comparison I conducted myself.
Additionally, the D7500 has a much improved RGB sensor for AF performance increase,
even with the same Multi-CAM system:
So, in the end.. the only thing similar to the D7100 and the D7500 is.. the F mount for lens.
After months of in-depth research, I chose to spend my $1,200 on a D7500 body for concrete reasons.
Yet I did go with the D7200 first, after being sorely disappointed in it's overall performance... even having
the dual card slots AND the camera grip module I felt my D5300 was about the same, maybe even better
in performance (YMMV).
What I found after 90 days with the D7200: Camera grip made the unit too heavy and cumbersome.
Shutter count with a singular battery was already impressive. Dual card slots are sought after for
the paranoid. If you are buying new cards on a regular basis the chance of failure hover around nill.
AF performance was no better than D5300 (YMMV). Image quality was equally good but with soft
focusing it could not be wholly appreciated.
What I found with the D7500:
Dual card slots are not critical, even for pros
Increased pixel count in the RGB sensor vastly improves AF performance even with the same Multi-CAM system as the D7200
I do not in the least miss the camera grip or the extra weight and cumbersome nature of it. Its easier and faster to just change axis.
(IMHO, the grip is a shiny ball, YMMV)
Flip screen is a great feature for out of position shooting
Touch screen feature is fully functional, and a pleasure to use
FPS capture rate is much improved for BIF, wildlife and sports: A++
There are a multitude of things that are a vast improvement, but I digress to each to do their own research.
After several months, I can see why JP calls it a "D500 Lite":
Would I like to have a D500? SURE! Do I *need* a D500.. Noooo.
For my budget constraints, it was a stress to tip up to the D7500, but in the end.. Im glad I ate all those
bologna sandwiches and other cost saving measures to pony up to it!
Am I a D7500 lover and enthusiast? Sure am! Because I actually got to USE it and found it to be worthy of my adoration.
Where we fall short as photographers is relying too much on reviews that are based solely on paper specs. When we pay
attention to only valid reviews... ones where a validated person actually used the camera and others in order to formulate
a comparison, then we get a real feel for it's capabilities.
I dont know about the others here, but... My pockets only go so deep. I have to save and sacrifice to buy gear.
So I may not have a lot of hands on comparison experience. But what experience I do have, I will freely share.
What is frustrating is shouting from the grandstands that is mostly regurgitating ignorance that has been proliferated by
anyone with a keyboard and an opinion. Exempli Gratia, the belief that not having a grip and dual slots makes it "not a serious camera".
Reality dictates, some changes had to be made to clearly distinguish it from it's nearest relative; the D500.
In closing, even a non photographer could easily look at the specs and see that the 7500 has far more in common with the 500,
than it does with any of it's predecessors. Is it a true 7200 replacement? I have my own conclusion but I urge each to
draw their own... but for the sake of realism, make it based on facts and not emotion.
