New wide angle and telephoto lens recommendations

[hokumto1]

Hello I have a EOS R8 and only have the “nifty fifty” I want some other lenses to use like wide angle and telephoto lenses. I’ve been looking at the 24mm f1.8 and 28mm f2.8 for ultra wides. And I would like recommendations on which to get. I plan on taking landscapes, street, and architectural photos so I want something versatile too! I’m not sure what to look at for zoom/telephoto lenses so any recommendations for those would be great too. My budget is 700 USD and I don’t want too go above the budget but I also don’t mind having something cheap.(for all lenses)

"I want some other lenses to use like wide angle and telephoto lenses."

That's not going to happen if you want a WA and a tele. $700 may get you one or the other but not both. As you have found the 50mm prime as an only lens is a poor choice. This time make sure you look for a zoom lens. The lens Canon ships with an R8 is the RF 24-50mm f/4.5-6.3 IS STM Lens I believe and it is a good place to start. I don't remember or know the price but it will be well under $700 bucks.

Hi and welcome:
24mm is not 'ultra wide' but it is wide enough for many landscapes.  If you want one lens that does a lot, extremely well then get the RF 24-240 IS USM lens.  It is an excellent optic with image stabilization, fast focus and covers a phenomenal focal range.  I have one and shoot with it more than my RF 24-105L f/4.

For $719,  which is only slightly above budget, you will get a refurbished one from Canon. These refurbs are often over-stock but new, new but open box, display or demo units, but 'good as new' and come with a Canon 1-year warranty.  You won't get a better deal!  Here is the link:
