I've started rediscovering photography again after a multi year break, and I've currently got a decision to make. I've started doing some more macro photography recently, and I'm to the point I would like to purchase a macro lens. However, I now realize that new DSLR cameras seem to be on their way out and mirrorless is what the major manufacturers are moving to. My current gear is a budget Canon DSLR with a kit lens, and a basic 75-300mm.
My question is this. Should I switch to a mirrorless camera before I spend more money on lenses? I don't have a huge amount of money invested so far, and whatever lens type I buy is most likely what I'm going to have to stay with for many years to come. My hard limit would be $1000 for the body, but preferably $700 or less. Since I would like to stay with Canon, that leaves me with the R100, R50, and RP at the very top end. I am open to other options however, especially if there are good aftermarket lenses and accessories.
Although I know there will still be new and used EF lenses available, I do worry a bit about future camera body upgrade options. I know I'm overthinking this a bit too much, but I'm just curious what other people think.
I rely pretty heavily on manual focus and focus peaking. Primarily because my main lens I find myself using is my 70-180 AF Macro with the FTZ adapter, which doesn't autofocus with the Z bodies. When using Z lenses (like the 24-120 S) then I'll use autofocus along with peaking.
