That Nikon does not have a native Z-series 24-240 mm (or close) all-in-one zoom kills me. I have a 24-240mm on my Sony a7 II and it is what I use 95% of the time. That is a good all-purpose zoom for I.
What I hate about the Canon EOS R family is the lack of In-Body Image Stabilization (IBIS). But, as Canon points out they do offer 5-stop Image Stabilization (IS) on some select RF lenses, the 24-240 being one of them.
Then the other lens that I might initially consider, the very-affordable 35mm MACRO also has IS.
I can live with just these two lenses for a long time. I really am not that fussy. Yes, I would like a decent f/1.4 50mm, just in case, BUT for this I am willing to consider an adapted lens.
And then there is the NEW Canon EOS RP.
Much more to my liking than the Canon EOS R. 30MP was overkill for I. I do not need that amount of resolution. I also hated the top LCD window. Don’t need it. Just adds weight and complexity. I have a 3″ LCD that has all the same info. So, the EOS RP is a much better match — though the 250 shot battery life is crushing (though I do walk around with 3 batteries for my Sony a7 II).
So, back to the drawing board again.
I want that 24 -240 and the Canon EOS RP looks like a good fit for it. Small and light. Ideal for my needs, especially when hiking. At 65 I really am not that keen about lugging 6 lbs of camera gear around.
