Canon R6 Mark II vs R6 Mark III: Is the Upgrade Worth the Price Difference?

The Canon EOS R6 Mark II came out in 2022 and became a common choice for weddings, events and action photography. In 2025 Canon announced the R6 Mark III, with an almost identical body but a new sensor, much stronger video and a different approach to storage. The question many photographers are asking is simple: is the newer camera worth the extra money, or is the Mark II, now considerably cheaper, still the smart buy?

The answer depends less on the cameras than on how you work. For pure stills, the two are closer than the price gap suggests. For video, the Mark III is in a different league. Let's go through it step by step.

What is different between the R6 Mark II and the R6 Mark III?

Data from PhotoFury product pages and Canon's published specifications, checked on 11/11/2026.

Laid out like this, the picture is clear: handling, viewfinder, screen and burst speed are the same. What changes is the sensor, everything related to video, and the way files are stored.

How much do 32.5 MP matter compared with 24.2 MP?

Going from 24.2 to 32.5 MP means a bit more than a third more pixels. In practice, that gives you more room to crop. If you shoot wildlife, sport from the stands or a ceremony from the back of a church, being able to tighten the frame and still have a good-sized file is a real advantage. It also shows in large prints and in product or landscape work where the client asks for fine detail.

For everything else, 24.2 MP is still plenty. A wedding delivered as an online gallery, social media, an album or a medium-sized print will not show the difference. The Mark II's lighter files also take up less space on cards and drives, and they move faster on your computer when you are editing thousands of images per job.

One honest point: a higher-resolution sensor spreads the light across more photodiodes, and the Mark II has a well-earned reputation in low light. If you work mostly in dark interiors and do not need to crop, the new sensor alone is not a reason to switch.

What does the R6 Mark III add for video?

This is where the real gap is. The R6 Mark II records 4K up to 60p, oversampled from 6K, with Canon Log 3: a very good image for weddings, corporate work and social media. If you want RAW, you have to send it over HDMI to an external recorder, which adds weight, cables and cost.

The R6 Mark III records 7K RAW inside the camera, up to 60p in a 17:9 format. It also adds an Open Gate mode that uses the full 3:2 area of the sensor, in 7K at up to 30p. That is very handy if you deliver the same footage in both landscape and vertical formats: you shoot once and reframe in the edit for each platform.

Slow motion takes a big step too. The Mark II tops out at Full HD 180p, while the Mark III records 4K at up to 120p and, according to Canon, without a sensor crop. On top of that you get Canon Log 2 alongside Log 3, and a full-size HDMI port, which is sturdier than the Mark II's micro HDMI when you work with an external monitor.

If video is a significant share of your paid work, these improvements justify the price difference on their own. If you only shoot video now and then, the Mark II already covers that comfortably.

Is the Mark III faster for sport and wildlife?

In raw speed, no. Both shoot 12 frames per second with the mechanical shutter and 40 with the electronic one, and both use Dual Pixel CMOS AF II with detection of people, animals and vehicles. The Mark III refines tracking, but someone shooting a Mark II today is not going to miss pictures because of autofocus.

The Mark III's advantage lies in two details. The first is its pre-capture: with the shutter button half-pressed, the camera keeps buffering images and, when you press fully, it saves up to 20 frames from before the shot. With birds taking off or a goal being scored, that is the difference between getting the moment and being late. The second is the CFexpress Type B slot, which clears the buffer faster than an SD card and lets you hold long bursts without waiting.

Who is the R6 Mark II still the better buy for?

The R6 Mark II is the sensible choice for wedding, event, portrait or sports photographers who shoot video as an extra. It offers the same handling, the same viewfinder and the same burst speed as its successor for considerably less money, and that difference pays for a good lens.

The two SD UHS-II slots make sense too: SD cards are cheaper and, if you already own a few, you do not need to invest in a new format. The same goes for the LP-E6NH battery, shared with many other Canon bodies from recent years.

If you are just moving to full frame, the kit with the RF 24-105mm f/4-7.1 IS STM, around €1,850, gives you a light zoom of about 395 g that covers everything from landscapes to portraits.

Who is the R6 Mark III worth it for?

The R6 Mark III is built for the true hybrid professional: someone who covers both stills and video at the same wedding, or produces brand content in several formats at once. Internal RAW, Open Gate and 4K at 120p save you an external recorder and give you far more room in post-production.

It also makes sense for wildlife or sports photographers who crop often and want pre-capture. And for anyone buying with many years of use in mind: it starts from a more modern base, with more resolution and faster storage.

Keep the cost of the system in mind. To get the most out of internal RAW and long bursts, a fast CFexpress Type B card is advisable, such as the Angelbird AV PRO CFexpress 1TB, around €400. The camera also uses the new LP-E6P battery.

Which lenses should you pair with either camera?

Both use the RF mount, so any lens you buy now will still work if you change bodies later. Three options cover most jobs:

The Canon RF 24-70mm f/2.8 L IS USM, around €1,980, is the standard zoom for weddings and events, bright and stabilised. For portraits at a distance, sport or ceremonies, the RF 70-200mm f/4L IS USM, around €1,290, is much more compact and lighter than the f/2.8 version. And if you want a bright prime without spending much, the RF 50mm f/1.8 STM costs around €180 and gives background blur that no basic zoom can match.

So which one should you buy?

Choose the R6 Mark II if you mainly shoot stills, video is an extra and you would rather spend the price difference on lenses. It is by far the better value of the two.

Choose the R6 Mark III if you are paid for video on a regular basis, need internal RAW or 4K slow motion, or often crop your wildlife and sports images.

Do not buy the R6 Mark III if all you want is the Mark II's speed and autofocus: there, they are practically the same. Do not buy the R6 Mark II if your plan is to record RAW without external accessories or to deliver vertical and horizontal versions from a single take.

Frequently asked questions

Do both cameras take the same lenses?

Yes. Both use Canon's RF mount, and both also accept EF DSLR lenses with Canon's mount adapter.

Can I use my R6 Mark II batteries in the R6 Mark III?

The Mark III comes with the new LP-E6P battery. Before relying on your LP-E6NH packs as your main batteries, check Canon's manual for any features that may be limited with them.

Do I need a CFexpress card for the R6 Mark III?

The Mark III has one CFexpress Type B slot and one SD UHS-II slot. If you plan to record internal RAW or shoot long bursts, CFexpress is the recommended choice, as it is much faster than SD.

Have the viewfinder and screen changed?

No. Both have a 3.69-million-dot OLED viewfinder with a refresh rate of up to 120 fps, and a 3-inch, 1.62-million-dot fully articulating screen.

Is the R6 Mark II now outdated?

No. It still delivers 40 frames per second, very reliable subject-detection autofocus and high-quality 4K 60p. What it lacks are the Mark III's advanced video features.
