I have an old Canon T3i that I'm looking to replace/upgrade.  I purchased it new in late 2011, and I've been using it ever since.

 

Ideally the replacement camera would for daytime use too, but I want it to be preform at night to get widefield shots and make timelapse videos.

 

I have a number of EF and EF-S lenses, so I would like to stay in the Canon family.  I had a good experience with a rented 90D, but I found out that Canon has ended development for DSLRs in favor of MILCs.  I've also read that users have had a positive experience with the adapter and that it just sort of "lives" on the body.

 

Ideally, I'd like for whatever camera body I choose last for another 13 years.  What do you think would be a better fit for me?

T7i or T8i ?

 

I really like the T7i, also for daytime pictures and good for astro too

Well the new mirrorless types are going to have better and faster hardware over all but the caveat is that they no longer directly fit the EF lenses unless you use an adapter for them.  The 90D was good for its design and the newer R7 has better pixel count and smaller ones too, this will help with better detail on astro-images.  In either case you might want to consider astro-modifying them if you plan to do a lot of nebulas or other colorful sources since the Ha performance is reduced due to a restrictive IR filter.  This is true of most DSLR cameras, including your current T3i.  Oh and for doing daytime photographs once astro-modified, all you really need to do is add an external IR/UV cut filter to the lens, that's not that expensive to do.

Thanks for the reply.

 

To be clear, I don't intend on using it with a scope and astro modifying it.  I have a cooled CMOS camera for that.  The replacement for my T3i would be for daytime use, but occasionally timelapse or widefield night sky imaging.  I specificly asked about the 90D and the EOS R7 because they are both APS-C with the same megapixel count (same image sensor?) 32.5MP.
