Looking for info on K7 over K20D

Hello All,
I just scored a Pentax k-7 (used) from an online equipment company (reputable...) Reportedly, it only has a shutter count of 3500+ (body only, but with original packaging...)

I've been shooting Pentax since the 1970's and my current setup is my K-1 and a brand new (two years ago) K-20-D...
All my glass is either SMC manual or late model Pentax "Auto" full frames, a couple of Pentax APS-C lenses, along with a couple of Sigma's and Tamron's thrown in to fill gaps.

So, my question is this... Is there anything in particular, that I need to be mindful of, with the K7, that may be different than my K-20 or K-1...? (Good Bad or Indifferent?)

BTW: So as, not to confuse anyone, I was cruising an on-line used camera seller for a replacement for my old K20D (that came up with a sensor problem...) and this listing popped up for "New - Old Stock", so I jumped at it...
(Especially for the $250 price tag...)
I took delivery, opened the box, put my 18-55 lens on it and took a few pics around the house... Downloaded them and sure enough the pictures came out as 101-K20-001 through 005... (I set up my file system to read "K20" to separate them from my K1 shots in my photo file storage).

I did notice that I can shoot video with the K-7 and not the K20D... but is there many other differences... like maintenance or trouble issues perhaps?

Thanks in advance for any advice .

If you want to confirm your K-7's shutter count, you can upload a JPEG here: Check Camera Shutter Count and Manufacture Date

here is the side by side comparison tool set up to compare the two

I you wanted IQ similar to your K-1, a K-5 would have been better.

The K20D and the K-7 are the two only Pentax cameras that have a Samsung sensor, so the image quality is very close between the two. The K-7 is the updated version of the K20D sensor, with a readout for video having been added.
The bodies are quite different... the K-7 has the magnesium alloy body so it is a bit of a step up over the K20D's body, though the K20D is no slouch in terms of ergonomics and build.
Neither one is going to come close to the dynamic range and high ISO performance of the K-1, there's going to be a huge, huge difference. But the K-7 will be a little bit closer in feel.

You should find stopdown metering with non-A lenses to be quite a bit more predictable than with the K20D.

One thing the K20D has that disappeared thereafter, is the handy dedicated on-body bracket button.

Video meant a slight difference in sensor and electronics. A lot of users suggested the K-7 was a bit worse in noise because of that, but it wasn't a huge difference. I don't remember any reliability complaints with the K-7. It was odd that some people had the lens lock button fall off the K-5, basically the same body. Build quality was pretty good.

The K-7 is more compact, better rear screen, and with more customizable buttons

What you probably notice is that K-7 feels like a much more refined design and UI than K20D.
IMO K10D/K20D feels like old cameras today, but K-7 feels like it could have been released yesterday.

K-3 III is the first APS-C flagship that make a major leap in camera design and UI since K-7.
(K-5 series was basially the same design a K-7 but with much lmproved IQ, and K-3/K-3 II versions a minor update on design and major update on performance and IQ).
