entry level photography seeking to purchase

[KMR13]

Hi. I have been reading a lot of info here and talking to photographers. I'm still a bit stuck in regard to my purchase. I owned a canon rebel DSLR from 2003- 2017 until the shutter button broke. along came the iPhone and kids and I never replaced that camera--but it's time. I have used my in-laws D90 (nikon) and while a beast it is a great camera.
I know the following:

• go mirrorless
• choose between full frame and crop sensor based on type of photogphy
• choose a moderate priced body style within my budget & save $ to put into the glass (3 pros told me so)
• I am NOT interested in uploading my life to vlogs and social channels--I'm looking to take pictures so video is less important to me-- nice to have
• photos I like to take:  beach, woodlands, interning buildings, pets, family. I spend lots of time in Florida where ehe birds are big and generally strike a pose for you! my daughter has 2 years of competitive swim left and I enjoy capturing those moments (did fine with borrowing the D90 last summer for that)
• Ideal to have In Body Stabilization, but not essential with good lenses
• I like a solid grip, but that's not primary reason to pick one camera over another
• make sure there is a wide variety of lens options (e.g. full frame can take APS-C lenses but not vice versa)
• weather seal may be a consideration-- sand, salt, mist, humidity....Florida, pool decks, etc
• will join a club and would like to submit to contests as I did this in the past...so much relearning to do now!
  
  I have read about and likely have over read (hence my indecision) about the r100 (ruled it out) the R50, RP, and R10 and R8 and I really don't know which way to go. I also have read that Sony is crushing the market with its technology, but not sure they are in my price range.  Someone suggested the Nikon Z5 or z50, but not sure those are for me either.
  
  Budget--I'd like to get a solid base to RE-learn and grow with and a really good lens for under $1,000 (with holiday sales, this should be within reach). I am not opposed to used or older model base if at a great price. Ex: someone suggested getting an RP, if at a good price, and learn and grow with that....
  
  I have heard the R50 is really entry level and better for the jet setting vlogger... the R8 has a serious overheating problem. I also read that some of these "dainty" APS-C cameras can barely hold the larger lenses so it makes for awkward/off balance holding of the body and lens....
  
  Looking for suggestions.... straightforward and straight-up. Thank you!

For the very simple reason of focal length is why you would go full frame.

For example, I own the 28mm "pancake" lens.

On my R8 it is a 28mm wide angle.

On my R100 it is a 45mm "nifty fifty" standard lens. 

The crop factor of the smaller sensor multiplies the focal length by 1.6.

Hi... I am going to a vendor event this Friday and hoping for a good deal on the R8 -- I'd prefer to go full frame as I've only ever shot with DSLR full frame AND I have 2 EF lenses that I can use on an R8 with an adapter.
The R10 would be my second choice.... and with buying adapter and RF lenses sounds like I'd still spend about the same as if I bought an R8.... 

[KMR13]

see my post above...to "krahe" --- about pricing R8 with RF/EF lens + adapter versus R10 with adapter & RF lenses.... seems like I'd spend about the same with the latter scenario and not have full frame!

That would drive me nuts.... maybe when I'm retired and my attention span is not spread across kids in college, work, home, and multiple other schedules I'll have the mind bandwidth for extra math with camera lenses. 😅. I kind of like the security of knowing I'm using THIS lens for THAT purpose and not have to mathematically adjust THIS lens to THAT camera body and its resulting difference in focal length. - maybe it's not as complex as it seems to me... but it does seem that way.

All sensors can be full-frame if the lenses are designed to cover that frame without cropping.

A company like Canon is always going to have professional, advanced amateur, and mass market choices and likely a smaller sensor for a lower price point.

Granted I'd love a full-frame Canon R200 (R100 + full frame sensor) for $699 as a back-up body, but that's a bit of an out-there wish.

The bulk of Canon's lenses are designed for full-frame coverage, though they have optimized some lenses for the APS-C sensor. Those optimized lenses for APS-C will not cover full frame.

Canon has also done backward compatibility with EF lenses most of which were optimized for full-frame 35mm and then full-frame digital, so it seems that they have committed to full-frame.

The R8 is an astoundingly good camera for a very attainable price point. I bought one the second they were out and have not regretted my choice in the least. The crop factor is most notable if you are using a given lens with full-frame and APS-C bodies back-to-back.
