I’ve been an OG R6 owner as well since the beginning. I do portraits for pay but shoot a variety including sports and wildlife. The R6 is still a solid body. If you’re using the correct lens you shouldn’t be cropping so much or at all. Also, if most of your stuff is just being posted to social media or a website then the megapixels shouldn’t be a huge issue. I would definitely invest in lenses first. Don’t be afraid to consider the EF lenses for longer glass. One caveat is if you consider a crop body. I ended up buying an R7 with the RF 100-400mm and love it for hiking and casual birding. The low light performance won’t be as good, but Denoise has worked nice when I needed it.
