I have $. That's not an issue. Just talking about THIS LENS and what are the benefits if paired with a r5! That is all. I'm rich, beeyotch. So if If I pair it with my 70-200 RF and 15-35 F 2.8, just looking for the best uses of the item talked about in this thread.
Thanks!
Well, a fool and their money are soon parted, as has been said before.
I didn't suggest not acquiring an R5 on the basis that you would be constrained in other ways by doing so, though it is certainly a valid reason to follow what I said.
If your goal is to be a camera collector instead of a photographer, and you simply want to own the best and money is no object, then go buy the RF 50mm f/1.2. It's a way better lens than this will be, almost certainly at all f-stops until at least f/2.8 or f/4 where the overall IQ will probably be very similar any smaller. It also has more rings for more utility in its use. Weight is not a factor because you already have 2 big heavy lenses and are a collector, not a photographer in the field.
A 50mm lens of any kind certainly covers a focal range you don't have. A zoom like the RF 24 - 70mm f/2.8 (or the smaller EF f/4 + adapter) more explicitly covers every focal length you don't have with minimal crossover, the RF 28 - 70 f/2 would be even better with less crossover, and a 24 - 105 (either one in RF) is probably a lens with more utility unto itself, even if it crosses into areas covered by both of your existing lenses. You may still want a 50mm fixed lens, and possibly others, even if you have zooms covering the range - I do, I have 28 f/1.4/50 f/1.2/85 f/1.4 in addition to my zooms.
But you self-identified as a n00b and your question would have revealed that even if you didn't. If you don't even KNOW whether a lens like this is a good choice for you, you have a lot to learn, because this is the most common lens type available, and as a fixed lens of a certain size and aperture, does one specific thing. And that's why I suggested a different camera body than the R5 - the R5 "is the best" but it is very complicated, and gives some very advanced tools to a knowledgeable photographer who can use them. Someone who is still learning would be better served by a simpler body, and no I'm not suggesting getting a manual-focusing film camera or anything like that. But if you were to shoot with an RP for example, you would find it much easier to work with in some ways (as well as being more compact to carry around), and then in others you would eventually run into limitations that would ideally be resolved - possibly by the R5, possibly by something else. And as a n00b, the image quality differences between the two are not yet relevant to you - there is certainly no technical reason a great shot on the RP wouldn't be able to be blown up to art gallery or billboard size, or entered into a contest. Far worse cameras than that have been used for such purposes.
This, again, assumes you want to learn how be a photographer, learn how to take good photos. You didn't ask if this would be a good lens relative to what you shoot or intend to shoot, so maybe that's a faulty assumption on my part. If you just want to be a camera collector, then continue on.
