EF 50mm 1.8 vs RF 35mm 1.8 vs EFS 24mm on a Canon R?

I’m looking at purchasing the RF 35mm 1.8 as I want another lightweight lens as a walkaround during festivals as such.

I love my 50mm so much, but sometimes I wish I could capture more of the scene and crop as I wish in post. One example is a fairly small stage that even when I’m right at the back on the marquee - I can only just get the whole band in view.

I do have the 24-105 L series but it’s too heavy to have with me all day, I save that for when I really need to zoom in.

Am I right in thinking the 35mm gives me a greater field of view? I was looking at a cheapy EFS 24mm pancake otherwise - which Google tells me crops to 38mm but may have a problem with vignetting.

I tend to photograph people and musicians, indoors and out.

If you were me, would you go for the RF 35 or EFS 24?

Thank you!!

I will leave the choice of focal length up to you.  You listed a variety of focal lengths.

It is better to use an RF mount lens on an R series body, over using an EF mount lens with the RF-EF mount adapter.

If you find the 24-105mm too heavy, then I would recommend the upcoming RF 28mm f/2.8 STM, or a similar wide angle prime for the RF mount.

Yes, a 35mm lens will give you a wider field-of-view than a 50mm lens (horizontal angles about 54º vs 39º respectively).

The RF-S 24mm lens would have a horizontal angle of around 49º.  So you'd be better off with the RF 35mm.

You're not clear about what camera you're talking about.  When you say "Canon R", do you literally mean the Canon EOS R?

On a full-frame camera, like the R, an EF-S lens is a bad idea.  It will put the camera into crop mode, which means you will get a narrower field of view -- that EF-S 24mm lens would give you a field of view equivalent to to a 36mm.  (It's still a 24mm lens, but the camera is reading a smaller part of the image.)

Worse, you will only be using a percentage of the camera's pixels, so you will be getting much less resolution than you're paying for, like 11.6 megapixels instead of 30.1.

OTOH, if you're looking at APS-C cameras, like the R10, then it doesn't matter.
