Honestly, would you buy ...

I recently bought an Rp. I think if Z5 would have been announced before that, it would have been a hard choice, but the money math still favors Canon.

Rp was  $999 with kit lens. Z5 is $1699. That's a lot of money at this price point.

Or Rp 24-240 kit is $1499 vs Z5 24-200 kit is $2199!

The 24-50 kit lens is nice and small, but the range is also laughable. I'd rather just have a 28 or 35mm prime, honestly. There's no way anyone would be happy with a slow 24-50 as their only lens. So you pretty much have to plan on buying a second lens to start with, too. The 24-105 or 24-240 kits that the Rp comes with have ranges that could easily be an only lens.

Canon Rp, 24-105 4-7.1, 35mm f1.8 and 85mm f2 come out to $2400 full retail, but if you wait for another sale, it could be $2100. If we do the 24-240 kit we are at $2600 total. And we get 1:2 macro, potentially saving another lens purchase down the road.

Z5, 24-200mm, 35mm f1.8 and 85mm f1.8 come out to $3850. I don't feel the 24-50 kit is worth including due to range as mentioned above, But even with 24-50 kit we are still at $3350.

So while it seems like it's just a tiny bit more expensive, as a kit, we are talking over $1000 difference for RF vs Z mount.

I think Nikon Z wins for mid-rangers. The primes are all f1.8 with outstanding optics. And they have a great lineup of f4 zooms that are still compact. Everything is weather sealed. I think many people consider the cheaper Canon RF lenses to be just a little too low end, but don't have the budget or bag space to step up to Canon L lenses. Nikon Z would be perfect for them. Canon wins for budget or ultra premium.
