Canon 100-400 RF f/5.6-8 IS USM Lens
For $600 USD, this is an absolute STEAL of a lens. It is also very light, and has sufficient sharpness and focusing speed. The biggest negative is it is f/5.6-8, which means it is mostly an outdoor lens, and you wont be using it in low light without your ISO cranked through the roof. Even though I own the 100-500 RF, Im still hanging on to this guy as I travel extensively, and therefore has a specific use in my tool kit. Highly recommended if you are a budget and looking for a tele RF zoom.
Canon RF 600mm f/11 IS STM Lens
I bought this last second before my first trip to Africa, which I had to bring on a Safari. It did not disappoint! There are a couple quarky things about it:
1. It is fixed at F11.
2. It requires “unlocking” to use.
3. Focusing is limited to a central area.
Those 3 things considered, this is the first you should get if you are considering the 600 and 800 f11s. The 800 is also great, but its bigger and doesn’t seem to be as sharp. This is a daylight Lens, but you will LOVE it for birding and wildlife.
Canon 28-70 f2 RF
This is a magical lens. HUGE, but magical. Why? Its as sharp as most of the EF L series lenses we saw and it is a zoom. INCREDIBLE image quality. Heavy. However, if you are a professional (think wedding) who relies on primes in the past, you might want to look at this. Over $3000, but justified if you are using to bring home the bacon, and want a lighter camera bag, instead of carrying several primes.
Canon RF-S 18-45mm f/4.5-6.3 Lens
Tiny & lightweight. My view on this one thought is the 18-150 is going to give you a tremendous more advantage for the extra $100, without adding much more weight. I can see this being good for vloggers who want the bare minimum.

Canon RF-S 18-150mm f/3.5-6.3 IS STM Lens
This is one of the new RF-S lenses that came out with the Canon R7. It is sufficiently sharp, and the focal length range are wonderful for the size and weight. This would be a perfect walk around / travel lens with the R7, especially if you do not own or plan to use and Full Frame RF Canon cameras.
