Finding the perfect zoom lens for your Canon EOS R50 shouldn’t feel like a financial burden. While the R50 is a compact …

Caught this a bit late but hope you havent bought yet. I've tried many budget lenses over the years and honestly, the Canon EF-S 55-250mm f/4-5.6 IS STM is still a total gem compared to the newer native one. Its noticeably sharper and having f/5.6 at the long end instead of f/7.1 is a big deal when youre shooting wildlife in the shadows of the mountains. If you can find a killer deal on a used site tonight, keep an eye out for a Canon RF 100-400mm f/5.6-8 IS USM. It might be a tiny bit over $350 but the reach is way better for birds and the AF is blazing fast on the R50. But for a hard budget limit, just get the EF-S 55-250. The bulk from the adapter isnt that bad once its actually in your pack, and youll be way happier with the image quality compared to the 55-210.

To add to the point above: will you be in deep woods or open ridges? I once used a Canon EF 70-300mm f/4-5.6 IS II USM for goats because 210mm usually feels kinda short.

Honestly, its kinda disappointing that the newer native options feel like a step down in some ways. I had issues with the Canon RF-S 55-210mm f/5-7.1 IS STM because that f/7.1 aperture at the long end is just way too slow for wildlife in the woods. Youre gonna see a lot of grain in your shots. Unfortunately, the older Canon EF-S 55-250mm f/4-5.6 IS STM is much sharper and lets in more light, which is technically what you want for birds. Heres my take for your $350 budget:

• Get the EF-S 55-250mm STM used (must be the STM version!)
• Pick up the Canon Mount Adapter EF-EOS R used or a cheaper Viltrox EF-R2 Mount Adapter
• Use the leftover cash for a spare battery The extra bulk of the adapter is a bummer for a long hike, but the RF-S image quality just isnt as good as expected compared to the old glass... it's a tough trade-off.

Building on the earlier suggestion, I have found that reach is usually way more important than aperture when you are shooting in broad daylight on a mountain.

• Try to find a used Canon RF 100-400mm f/5.6-8 IS USM. It might be slightly over $350, but the extra 150mm of reach makes a massive difference for birds.
• It is much lighter than an EF lens plus an adapter.
• The focus speed is basically instant compared to the older budget zooms. Funny enough, I actually switched to the R system specifically because my old DSLR kit was getting way too heavy for the Rockies. Last summer I brought a massive setup to Glacier and honestly I spent more time checking my straps than looking for bears. My knees still havent forgiven me for that 10-mile trek with 15 pounds of glass in my pack. Now I basically just bring one or two light lenses and actually enjoy the hike instead of just suffering for the sake of a photo. But yeah, definitely try to get more than 210mm if you are serious about those goats.

Good to know!
