> Looking for a great landscape lens for my Canon R8! Honestly just saw this and felt compelled to chime in. It drives me absolutely crazy that we still have to compromise so much on compatibility and build quality lately. In my experience, you are either lugging around an adapter that feels like a weak point in your gear chain or you are buying plastic lenses that dont feel like they belong in the woods. It is so frustrating trying to find that perfect balance between weight and not having your gear fall apart. To add to the point above, I have spent a lot of time weighing these two:

• Canon EF 16-35mm f/4L IS USM: Used to be my go-to. Solid as a rock. But honestly, using it with the adapter on an R8 is such a headache. It is front-heavy and I am always paranoid the mount is gonna give out during a steep climb. The extra length from the adapter just makes everything feel clunky.
• Canon RF 15-30mm f/4.5-6.3 IS STM: Native is better for the electronics, sure, but the lack of weather sealing is just terrifying when clouds roll in. I hate having to baby my gear every time it starts to drizzle. It just sucks that there isnt a perfect middle ground for us yet without spending way over budget. I have been through so many setups and the compatibility trade-offs still bug me every single trip... stay safe out there tho.

Basically everyone's ignoring the native wide zoom that actually fits ur budget lol. If you're hiking mountains, you want something light and stabilized since the R8 lacks IBIS. Honestly, I've been using the Canon RF 15-30mm f/4.5-6.3 IS STM for months now and it's a sleeper hit for technical landscape work despite not being an 'L' lens. * The 5.5 stops of Optical IS is a lifesaver for blue hour forest shots where you cant use a tripod.
* Technical performance-wise, the MTF charts show it actually holds more corner resolution than the old 17-40mm L glass when you stop it down to f/8 or f/11. Its also got a really decent 0.52x macro magnification at the wide end which is great for those close-up textures on trees and rocks. Its probably the most logical long-term investment for a lightweight R8 setup tbh.

Finally someone says it. Ive been thinking this for a while but wasnt sure.

Helpful thread 👍

Bump - same question here

Been rocking the Canon EF 17-40mm f/4L on my R series (with adapter, obviously) for years. Solid performer in those environments. Images are sharp enough, build quality is fantastic, and you can usually snag one used for around $400. Downside? It's not native RF, but it just *works* for me. Decent option to consider.

For your R8, consider the Canon RF 16mm f/2.8 STM. Compact and sharp, but chromatic aberration correction in post is crucial. Test thoroughly, and get professional advice to ensure it works well for *your* workflow; no complaints on my end.

Tamron's market share is growing. Consider their 17-28mm; user satisfaction is high, no reported issues.

Used EF 17-40mm f/4L! Adapts great, saves cash. Maybe $400? Check condition first!

Hey! For mountain/forest shots, be careful hiking with expensive gear. Consider a used Canon EF 17-40mm f/4L. It's tough, weather-sealed, and cheaper than new lenses – leaving budget for a really secure camera strap. A dropped lens is a ruined trip! Make sure to get a good UV filter too, protects the front element.
