> Based on popularity, performance, and versatility for video work, these three lenses stand out for your Canon EOS R6 Mark II Honestly, I feel your pain. I jumped into the RF system expecting everything to just work, but unfortunately, I've had so many compatibility headaches lately. It is not as good as I expected, especially when mixing older glass with these new bodies. I spent way too much time troubleshooting autofocus issues that just shouldn't be happening at this price point. Late to the party here, but I've basically stopped looking for the perfect lens because the whole ecosystem feels a bit hit or miss right now. If you're really stuck, just go with any high-end glass from the big name brands that offer decent adapter support, but honestly? You might just run into the same frustration I did. It is a bit of a nightmare tbh. Just keep your expectations low and you won't be as disappointed as I was.

Been thinking about your question while out shooting today. Honestly, stop obsessing over those massive L-series zooms for a minute. If you really want that cinematic look for video, you should look at the Canon RF 16mm f/2.8 STM.

• It is super tiny and light, perfect for when you are running and gunning with the R6 Mark II.
• The focal length is wide enough for vlogging or tight indoor spaces without being too distorted.
• It is dirt cheap compared to the L-glass, so you have extra cash for a decent gimbal or better audio gear. Another solid sleeper pick is the Canon RF 85mm f/2 Macro IS STM. The stabilization is a lifesaver for handheld video when you need that compressed, professional look for interviews. I have been using both for months and have zero complaints. They just work well, no fuss, no firmware headaches.

The new released Canon RF 35mm F1.4L VCM is a notable addition to the EOS R6 Mark II. Its lightweight design and hybrid features make it an outstanding prime lens choice for both photography and videography.

3. Canon RF 85mm f/1.2L USM

   • Description: Another stellar lens from Canon's L-series, the RF 85mm f/1.2L is renowned for its sharpness, beautiful bokeh, and ability to create stunning portrait shots. Its telephoto reach allows for great compression and subject separation, making it ideal for cinematic storytelling.
   • Best For: Portraits, beauty shots, and narrative filmmaking.

For high end video lens, you can get the RF 24-105mm f/2.8L IS USM Z lens.

Jumping in here because honestly, I am right there with you on the frustration front. It feels like every time I think I have my R6 II rig dialed in, some weird focus hunting or micro-jitter pops up in the footage and it just drives me crazy. I have wasted entire afternoons digging through menus trying to fix issues that really should not be happening at this price point. It is exhausting when the gear just does not behave.

• How long are your typical shooting sessions?
• Are you mostly doing handheld work or are you stuck on a tripod all day? I am curious if you have noticed the same weirdness with your AF tracking when things get a bit dim. It is just so hit or miss for me lately, and frankly, I am getting pretty tired of it.
