What glass for EOS R7

[carvat]

So I just upgraded from 80D to R7. I'm just a bit lost to which lenses to keep/get. I have the RF-S 18-150 which I read is well rated, but it just seemed... Small. I know it's the dumbest thing ever to say but I was really taken aback at how cheap it feels, yet reviews seem pretty good. Mind you I also don't have great EF lenses so anyway all that to say, looking for advice.

I have an EF 70-300 USM II which I struggle with the softness at times for wildlife, a EF-S 18-135 (kit) which was fine I guess but not great, an EF-S 10-18 which doesn't seem well rated yet I really enjoy and finally a 50 1.8 which I barely use but is still quite fun.

I mostly do landscape with a bit of wildlife, and travel a lot so portability is a factor, but not to the point of sacrificing quality.

Which lenses would you say are musts, which are good quality for money (I'm a hobbyist) and which of mine could I repurpose with an adapter? Thanks

The EF70-300mm f/4-5.6 IS II USM lens is rather good, and I would suggest getting the Canon EF to EOS R mount adapter to use with it as an initial step with the EOS R7. This will help you determine if the lens is actually soft or if it was a limitation of the EOS 80D. 

The RF-S 18-150mm kit lens is quite a revelation and actually performs very well. I have one and it is sharp and good, while also being small and light. Great for a lens with an effective 28.8 to 240mm range. I certainly think it is better than the EF-S 18-135mm lenses. It is certainly a great travel lens in my view. 

The reality is that the EF and EF-S lenses you have can be used with the adapter on the new camera, and that is a good initial step. However there are other options with RF lenses. You might find that the RF 100-400mm lens is ideal for wildlife having a bit more reach than your current 70-300mm, and it is also great value. The downside is the f/5.6-f/8 maximum aperture which might need a little more light than your current 70-300mm. Don't be put off by its small size and light weight.

There is an RF-S 10-18mm lens that you might choose to replace your existing EF-S 10-18mm.
