Just got a Canon EOS R5. Which lenses will be best?

[taradeone]

I got my dream camera, the Canon EOS R5! I am beyond thrilled! I'm a huge fan of wildlife and landscape photography, and I also enjoy capturing people.

As you can imagine, after investing so much in the camera, I need to be mindful of my budget for the lens. I'm looking for something that will not compromise on quality but won't break the bank either. And, as I take a lot of trips to the PNW in the US, I'd love a water-resistant/waterproof lens that can withstand the elements. 

I'm exploring options in the range of 24-800mm and am open to getting multiple lenses. Does anyone have any recommendations?

I would love to have a good lens to where I can shoot photos from a short distance for landscape, but also a lens that can allow me to zoom in a far distance to shoot wildlife.

Before I had the Canon Powershot SX530 HS so I did not have any lenses. My budget is preferred to be $1,500 or under. Although, I am willing to spend more on multiple lenses.

Thank you so much for the reply. I am definitely going to look into the Sigma! It's definitely a little more budget-friendly than the 100-500.

In that case, I would recommend the Sigma 60-600 for wildlife , alternatively there is a cheaper lens also available that also works well with the R5, and that is the Sigma 150-600 Contemporary lens.  It too has excellent optics and it is also lighter because it does not have to cover the extreme focal range.  You will need a Canon EF-RF adapter to make either Sigma lens work with the RF mount.

For the lower end of the focal range, than the RF 24-105 or the RF 24-240 lens would be good choices.  The second one would give you more flexibility over a wider range of subjects, so that you don't have to take the large and heavier Sigma.

As I don't live in the USA, I shall leave the pricing for your own research.  I hope this helps.
