Need advice regarding buying an EOS RP

I have the RP kit with the 24-240 RF and the 35 RF.  Super happy with that set up.  Don’t know about the grip being needed. I’m 6’4” (193 cm) tall and can palm a basketball. I have no issues with the camera body size.

Bad things?  Be careful with your focus if your subject doesn’t completely fill the focus square. Noticed this first using spot focus on a bird where the focus square was slightly larger than the birds head. It tended to focus on something contrasty behind the bird that was also in the square.  When it’s close to your subject, it’s hard to tell in the EVF that you missed focus.  Didn’t notice until loading on the computer.

Now you can magnify just the focus point in the EVF and manually fine tune the auto focus, which is great,  but you have to be on one shot af and hope your subject sits still.  Maybe your 600 mm will put you close enough where this isn’t an issue.

Overall, agree with others.  Great for a hobbyist like me who’d rather spend the $1,500 price difference vs the R6 on food and clothes for my kids.

IBIS, to me, is a bit overblown. The RF lenses you’re looking at are stabilized.  If you’re as much of a novice / hobbyist as me - you don’t have a huge collection of old un-stabilized lenses laying around just waiting to adapt. For the rare occasion that light doesn’t allow for handholding, I’ll bring the tripod.  Funny how photography survived so long without IBIS and now we can’t live without it.
