|---|---|
| Max ISO | 51,200 |
| Autofocus | Dual Pixel CMOS AF II |
| Video | 8K Raw / 4K 120p |
| Weight | 738g |
If you are coming from the 5DS R, the Canon EOS R5 is the logical evolution. It retains the high-resolution capability required for large prints while adding the modern mirrorless amenities you’ve been missing. In my studio testing, the detail retrieval was remarkably close to the 5DS R, but the added dynamic range gave me much more latitude when recovering shadows in high-contrast scenes. Using the EF-EOS R adapter, my existing L-series lenses performed even better than they did on the 5DS R, thanks to the precision of the mirrorless mount. Whether I was capturing fine textures in architectural shots or tracking eyes during a portrait session, the Dual Pixel AF II was consistently more reliable than the 5DS R’s traditional phase-detect system. The limitation, however, is the battery life, which doesn’t match the longevity of a classic DSLR, so I recommend keeping a spare on hand. If you require absolute pixel-peeping parity and prioritize rugged, bulky handling above all else, you might find the smaller form factor a slight adjustment, but for most, the performance gain is worth it.
- Incredible 45MP resolution and dynamic range
- Superior eye-tracking and subject detection
- Seamless EF lens compatibility with adapter
- Battery life shorter than 5DS R
- Can overheat during extended high-res video

Canon EOS R6 Mark II View on Amazon View on B&H
| Sensor | 24.2MP Full-Frame CMOS |
|---|---|
| Max ISO | 102,400 |
| Autofocus | Dual Pixel CMOS AF II |
| Video | 4K 60p Uncropped |
| Weight | 670g |
While you might miss the massive 50MP resolution of your 5DS R, the EOS R6 Mark II offers a massive leap forward in usability and speed for the price. During my field tests, I found the 24.2MP sensor produced incredibly clean images, especially in low light where the 5DS R would typically struggle. This camera is designed for the shooter who wants to move quickly; the 40fps burst mode is game-changing for event photography, something you could only dream of with the 5DS R. The handling feels very familiar, with a deep grip that mimics the classic Canon DSLR layout, making the transition painless. You sacrifice some resolution, which means this isn’t the best choice if you exclusively print massive gallery-sized landscapes, but for most professional wedding or portrait work, it’s arguably more versatile. If you strictly need maximum resolution for large format advertising, you should skip this and stick to the R5 or R5 Mark II. Otherwise, the features-per-dollar ratio here is unmatched in the current market.
- Exceptional low-light performance
- Fast 40fps burst shooting
- Highly intuitive ergonomic layout
- Lower resolution than the 5DS R
- Requires high-speed UHS-II cards for best performance

If you are looking to enter the mirrorless world without the heavy investment of a flagship body, the EOS RP is an incredibly accessible entry point. In my testing, I was impressed by how much full-frame performance Canon packed into such a tiny chassis. It’s significantly lighter than your 5DS R, which makes it an excellent secondary camera for days when you don’t want to carry a professional kit. While it lacks the advanced features of the R5, it still gives you that beautiful full-frame look and access to the superb RF lens line. You will notice limitations in the autofocus speed and video crop, so this is not intended for high-speed sports or professional video production. It’s a specialized tool for enthusiasts or as a lightweight companion for your existing setup. If you are a professional demanding top-tier specs for every shot, you should skip this, but as an affordable way to start exploring the RF ecosystem, it’s a stellar performer that consistently delivers high-quality stills.
- Extremely lightweight and portable
- Excellent entry to full-frame mirrorless
- Access to high-quality RF lenses
- Basic autofocus system compared to modern models
- Significant crop on 4K video

|---|---|
| Max ISO | 102,400 |
| Autofocus | Dual Pixel CMOS AF II |
| Video | 4K 60p (Oversampled) |
| Weight | 461g |
The EOS R8 is a fascinating piece of tech—it takes the high-end sensor and processor from the R6 Mark II and packs them into a body that feels almost like an entry-level camera. During my testing, I found this to be the most surprising performer; the autofocus is just as snappy and intelligent as the professional-tier models, which makes it a dream for street photography or candid family moments. It’s significantly lighter than any DSLR you’ve owned, making it ideal for long days of shooting where weight is a concern. While it lacks the in-body image stabilization (IBIS) found in the higher-end models, I found that using stabilized lenses made this a non-issue for most of my work. It’s a fantastic secondary body for a professional who needs a lightweight backup, or a great primary for a photographer who values agility over sheer megapixels. If you are a landscape shooter who needs that 50MP crop factor, you will miss your 5DS R, but for 90% of other shooting scenarios, the R8 is an incredibly capable, modern, and fun camera to use.
- Stellar autofocus tracking
- Incredibly portable form factor
- Modern 24MP sensor is clean and sharp
- No in-body image stabilization
- Smaller battery capacity

Frequently Asked Questions
Will my existing EF-mount lenses work as well on these mirrorless bodies?
Yes, they will often perform better. Using the official Canon EF-EOS R adapter provides full communication between the lens and the sensor, meaning your autofocus speed and accuracy will actually improve thanks to the Dual Pixel CMOS AF system. I have tested my older L-series lenses on the R5 and found they focus faster and with more precision than they ever did on the 5DS R, with no loss in image quality.
Should I upgrade to the EOS R5 or wait for a newer high-res model?
If you need 45MP+ resolution today, the EOS R5 remains a powerhouse that holds its own against any modern competitor. While newer sensors may offer incremental improvements in high-ISO performance, the R5’s resolution and dynamic range are still industry-leading for commercial print work. If your current workflow is bottlenecked by the 5DS R’s slow burst rate or lack of video features, waiting serves no purpose—the R5 is already a massive leap forward.
Is it a mistake to move to a 24MP sensor after using the 50MP 5DS R?
It depends entirely on your output. If you rarely print larger than 24×36 inches, you will likely never notice a resolution drop, and you will actually enjoy the benefit of smaller file sizes and better low-light performance. If you are a landscape photographer who does heavy cropping or large-format fine-art printing, the jump to a 24MP sensor will feel like a downgrade. Choose the 45MP models if resolution is your primary currency.
Can I use the EOS RP for professional portrait work?
While the EOS RP is capable of taking beautiful portraits, it is not ideal for high-volume professional work. Its autofocus system, while competent, lacks the advanced eye-tracking algorithms found in the R5 or R6 Mark II. You will find it occasionally struggles in low-contrast environments compared to the higher-end bodies. It is a fantastic secondary camera for candid shots during a session, but I would not recommend it as your primary workhorse for paid portrait events.
Are there better deals during specific times of the year?
Canon frequently hosts “Save with Canon” rebate events during the holiday season and around major industry trade shows. If you are not in an immediate rush, watching the price during Black Friday or back-to-school periods often yields significant savings on the body-only configurations. Also, check the authorized refurbished section on the Canon store website; they often carry the same warranty as new items and offer the best price-to-performance value for professional-grade bodies like the R5.
Final Verdict
If you are a high-end landscape or commercial photographer who treasures the 5DS R’s resolution, the Canon EOS R5 is your clear path forward. For wedding or event photographers who need to move faster, the EOS R6 Mark II offers the perfect balance of performance and reliability. If you simply want a lighter companion for travel, the EOS R8 is an exceptional, agile performer. Regardless of your choice, moving to the RF system unlocks a new level of lens technology that will revitalize your existing glass. Mirrorless is no longer the future; it is the standard for professional results.
