> native RF communication is a big deal for the R6 Mark II Building on the earlier suggestion, I totally get the push for native glass. While everyone usually jumps to the heavy f/2.8 L lens, I am actually very happy with the Canon RF 14-35mm f/4L IS USM. Hear me out tho... unless you're shooting astrophotography or weddings in caves, that f/4 is plenty. You gain that extra 1mm on the wide end which is huge for interior work and landscapes. Technically speaking, it handles corner sharpness exceptionally well once the profile is applied. It works well with the R6 II IBIS too, giving you incredible compensation for handheld shots. If you want something tiny and fun, the Canon RF 16mm f/2.8 STM is also a solid native choice that wont break the bank. Its not L-series quality, but for the size, I have no complaints. Just my two cents after using the system for a few years now.

Caught this thread and I agree with Sebastian that native RF communication is a big deal for the R6 Mark II. The way the IBIS and lens talk to each other isnt something you get with every adapter. I'd just politely disagree that third-party glass is always a bad move for pros. I usually look at these points from a reliability standpoint:

• Long-term firmware support from the manufacturer.
• How the weather sealing actually holds up in the field. Native is definitely the safest bet for mission-critical stuff, but some of the other options are realy catching up. Just depends on your risk tolerance.

Saving this whole thread. So much good info here you guys are awesome.

Nah, I'm gonna have to disagree with the third-party suggestions here. If you're shooting on a body as capable as the R6 Mark II, you're realy doing yourself a disservice by not sticking with native Canon L-series glass. Tbh, the technical integration between the RF mount's high-speed communication protocol and the body is something the budget brands are still struggling with. You want that perfect synchronization between the IBIS and the lens's optical stabilization, especially for wide-angle work where corner smearing and chromatic aberration can be a total nightmare to fix in post. Honestly, just look at the MTF charts for any of the professional red-ring wide-angle options from Canon; the peripheral illumination and coma correction are basically industry-leading. Just go with any high-end native glass from the brand and you'll see what I'm talking about. The micro-contrast is exactly what that sensor was designed for.
