The Canon R6 Mark II is widely considered a top-tier versatile full-frame mirrorless camera, particularly praised for its class-leading low-light performance and significant autofocus improvements over previous generations. It is a popular choice for professionals transitioning from DSLRs, though it carries a premium price tag and some users report specific technical hurdles with its electronic shutter and subject tracking in complex environments.
Pros
- Exceptional low-light performance with minimal noise and reliable AF acquisition in dark settings.
- Advanced autofocus system with highly effective eye and subject detection for most scenarios.
- Seamless compatibility with older EF lenses via adapters, maintaining performance and image stabilization.
- Fast sensor readout speed compared to many competitors in its class.
Cons
- Noticeable rolling shutter artifacts (distorted subjects) when using the electronic shutter for high-speed action.
- Occasional autofocus inconsistencies where the system may track the wrong subject in crowded frames.
- Ergonomics can feel front-heavy when used with adapted EF lenses.
- Significant price point that may be prohibitive for students or casual hobbyists.

For low light, R6II is king, not just noise, but also AF acquisition and performance. I have the R5 and R6 and R6 is my go to in low light.
If budget isn’t an issue then get the R6 II or even the R5II.
The R6II has some of the best low light performance of any camera out there.
Honestly I'd say the R6 Mk II is the sweet spot right now between the Mk I, II, and III. The I isn't that much cheaper (about $1500 used vs $2100 at current discount) but the II has more megapixels (better for cropping e.g. in sports), significantly better autofocus, better thermals for video, 40 fps e-shutter, etc. — meaningful differences.
Parent context: I mostly prefer my R6ii over my R5ii Reply: Why is that? I am a content creator who does travel documentaries on YouTube and have been filming on the Canon 90D and 250D forever.

The Canon EOS 5D Mark IV is widely considered one of the greatest professional DSLRs ever produced. Even as the industry shifts toward mirrorless systems, it remains a highly respected workhorse for professional portrait and wedding photography due to its rugged build, reliable performance, and excellent image quality.
Pros
- Exceptional image quality and color science in both RAW and JPEG
- Extremely durable and rugged professional build
- Proven reliability for high-stakes event and wedding photography
- Excellent value on the used market compared to modern mirrorless equivalents
Cons
- Autofocus system is significantly less advanced than modern mirrorless eye-tracking
- Video performance is surpassed by newer, more affordable mirrorless bodies like the EOS RP
- Heavier and bulkier than modern mirrorless alternatives
- Incremental improvement over the 5D Mark III rather than a revolutionary leap

5Ds is a better camera, better file, though today I'd opt for a 5Div.
It’s probably the greatest professional 35mm DSLR to ever be produced, and since the world has gone mirrorless, it will likely hold that title forever.
Mark iv is a great camera but everything has gone mirrorless now. It doesn’t diminish the value of the Mark iv or its ability to get work done
This is a legend of a camera.
I bought mine in 2015 and used it a *lot* until my 5D Mark IV all but replaced it in late 2019.
