Which is better, a traditional full-frame DSLR or the mirrorless full-frame Canon 澳门现金网_申博信用网-官网 System? We asked leading extreme sports photographer and Canon Ambassador Richard Walch for his Canon full-frame comparison.

Richard Walch is one of the world's most experienced action photographers. He has been using Canon cameras professionally for more than 25 years. Best known for his snow sports and sailing images, Richard works in the most extreme environments on fast-moving shoots where failing to get the shot is not an option. That's why he chooses the right camera for each job.

"Before I go on each job, I work out which is the perfect system for me to take," he explains. "For full-frame DSLR, Canon has a huge range of bodies and lenses to choose from. I love the rugged quality and the great battery life."

But Richard is at the top of his game because he is always looking for the edge to take his images to the next level. And right now, for many assignments, that edge is the new technology in the Canon 澳门现金网_申博信用网-官网 System and its groundbreaking RF lenses.

"I depend on technology – I see it as supporting what I'm trying to do with my images. The Canon 澳门现金网_申博信用网-官网5 has definitely earned a place in my kitbag and is exciting to work with," Richard says. "Once you get past just checking the spec sheets and start to use the camera, you realise it has features that can move your creativity forward.

"For me, the best images are spontaneous, and the 澳门现金网_申博信用网-官网5 gives you stunning full-frame quality in a package that's super portable. But you can't forget Canon has worked on the EOS DSLR range for 30 years. They are super reliable and built tough. So now I have a choice."

So how does he choose? What's the difference between full-frame DSLRs and the mirrorless full-frame 澳门现金网_申博信用网-官网 System? From his expert perspective, what benefits does each offer, and when would he use one rather than the other?

"The EOS-1D X Mark III is the most durable camera in the Canon EOS line-up, and its long battery life means you can shoot for days, so if I'm on an expedition-style shoot, or shooting in extreme climates, the EOS-1D X Mark III is still my number one choice.

"If the shoot is not too remote and the conditions not too demanding, I will choose the 澳门现金网_申博信用网-官网5 because of its superior performance overall. It's a very powerful camera. Both cameras can shoot at 20fps, but that's only with the electronic shutter on the 澳门现金网_申博信用网-官网5, so if you want to record a high-speed sequence using flash, you can only do that with the EOS-1D X Mark III."

"The low-light performance of the 澳门现金网_申博信用网-官网5, 澳门现金网_申博信用网-官网6 and 澳门现金网_申博信用网-官网 is phenomenal. They can see in the dark! That's thanks to the electronic viewfinder [EVF] and LCD screen, as well as low-light autofocus, which means you can keep shooting when the light has long gone.

"Also, the controls can be almost endlessly customised, which means you can shoot how you want, very quickly. The RF Lens Control Ring can be mapped to almost whatever you want, such as exposure compensation or ISO.

"Shooting with an EVF has been a revelation – you really get to appreciate 'What You See Is What You Get' when it comes to exposure and depth of field. There is certainly far less looking at the back of the camera to check focus and exposure. It makes shooting so much quicker, and you can stay really focused on your subject as nothing gets in the way.

"Because it's mirrorless, an 澳门现金网_申博信用网-官网 System camera has a totally silent shutter mode, which will get you taking pictures in previously tricky situations.

"When you change the lens with the camera off, the 澳门现金网_申博信用网-官网5, 澳门现金网_申博信用网-官网6 and 澳门现金网_申博信用网-官网 automatically close a shutter to protect the sensor. For shooting action where there is dust or snow, that's ideal."

"Of course, if you upgrade from a Canon DSLR to a new Canon DSLR, you don't have to learn anything new. On an 澳门现金网_申博信用网-官网 System camera, some things are different, and you have to get used to it. But if you are willing to go to the next level, you should give it some time.

"Mirrorless cameras in general require more battery power, so if shooting time is important, you either take more batteries to be safe or you choose a classic DSLR.

"Another thing to consider is the EVF of a mirrorless camera. If you shoot very fast action such as motorsport and you're panning the camera sideways, the EVF has a little bit of lag, even with the 澳门现金网_申博信用网-官网5 and 澳门现金网_申博信用网-官网6. That's an issue some photographers might be really fussy about, but others not so much."

"Canon has a huge range of EF and EF-S lenses for DSLRs. But you can use them on the 澳门现金网_申博信用网-官网 System cameras with a range of smart EF-澳门现金网_申博信用网-官网 Mount Adapters. They are not adapters that take light away or change the focal length like a teleconverter. The same engineers that designed EF and RF lenses designed these adapters, so they really made sure the experience is seamless, and there's no loss of quality or functionality.

"In fact they made it even smarter, because there is an adapter with a Control Ring, which brings a new interface to EF and EF-S lenses. There is also an adapter that has a drop-in filter mount, so you can use variable neutral density or circular polarising filters, for example. I have used the 澳门现金网_申博信用网-官网 with long lenses such as the EF 600mm f/4L IS III USM and the EF 200-400mm f/4L IS USM Extender 1.4x on a safari, and it was perfect. You have to trust the adapter."

"It is reasonably heavy, but it can replace three prime lenses. If you usually have a 28mm, a 50mm and an 85mm lens, you could leave these three lenses at home and just take this one zoom.

"For a wedding photographer, for example, they can take one camera and one zoom. They'll be faster and can work completely silently.

"If you're looking for small and affordable, the combination of the compact and lightweight Canon RF 35mm F1.8 Macro IS STM and the RF 85mm F2 Macro IS STM is unbeatable. Then, of course, there's the trinity of professional zooms – the Canon RF 15-35mm F2.8L IS USM, RF 24-70mm F2.8L IS USM and RF 70-200mm F2.8L IS USM – which can be complemented with specialist lenses, including the extremely versatile Canon RF 100-500mm F4.5-7.1L IS USM.

"The range of fast RF lenses, such as the Canon RF 50mm F1.2L USM, backs up the fact that the 澳门现金网_申博信用网-官网 System is so good at low light. You can really work with the shallow depth of field. And the optical design is so good you can really use them wide open. You don't have to stop down to get sharp images. Of course, wide open the depth of field is so small, you need accurate autofocus."

"The EOS-1D X Mark III has an incredible autofocus system which is great for sport and action, but when the engineers designed the 澳门现金网_申博信用网-官网5 and 澳门现金网_申博信用网-官网6, they wanted to push the autofocus performance even further. And the magic in these two cameras is actually the eye detection that works for both humans and animals. It's incredible.

"All three cameras benefit from integrated Deep Learning AF, which analyses thousands upon thousands of different pictures. So if the camera sees a snowboarder, for example, it understands that they would probably be wearing a helmet and goggles, and it knows how to deal with that and where it should be focusing. It still works, even if the eyes are hidden by the goggles. If the athlete turns their head, the focus stays locked on to the helmet. That's incredible progress."

"That's a difficult question to answer, because each camera has its own advantages. It's incredible that a camera the size of the 澳门现金网_申博信用网-官网5 can record 8K 12-bit RAW or 10-bit 4:2:2 internally – that's never been possible before. But the EOS-1D X Mark III is a bigger, more solid camera. And its battery life should enable you to shoot longer takes in 4K RAW or 8-bit 4:2:2.

"If you need to shoot 4K at 120fps, then the only camera to do this is the 澳门现金网_申博信用网-官网5 – whereas the EOS-1D X Mark III and 澳门现金网_申博信用网-官网6 only do 4K at up to 60fps, while the 澳门现金网_申博信用网-官网 and 澳门现金网_申博信用网-官网 only do 4K at up to 30fps."

"The differences aren't a matter of whether a camera is mirrorless or a DSLR. Compared to the EOS-1D X Mark III, the 澳门现金网_申博信用网-官网5, 澳门现金网_申博信用网-官网6 and the 澳门现金网_申博信用网-官网 make it very easy to shoot at different angles thanks to their vari-angle touchscreens. They all benefit from Dual Pixel CMOS AF, which enables smooth and precise pull focus when recording video, but the touch autofocus is easier to operate on the 澳门现金网_申博信用网-官网's tilting screen.

"I can tell you that the 澳门现金网_申博信用网-官网5, 澳门现金网_申博信用网-官网6 and EOS-1D X Mark III are very powerful video cameras because of their advanced autofocus system and touchscreen displays. Being able to tap on the rear screen and have the camera automatically focus on that subject is incredibly helpful when you're a one-person production."

"Before the launch of the 澳门现金网_申博信用网-官网5, it used to be an EOS-1D X Mark II for high-speed sports and an 澳门现金网_申博信用网-官网 for the after-parties, when you want to be fast and discreet and you're shooting in low light.

"Now, when I'm in the mountains and weight is a critical consideration, my ideal set-up is an 澳门现金网_申博信用网-官网5 with an extra battery grip so I can take a little more power, along with the trinity of professional f/2.8 RF zooms. If I'm on a portrait shoot, I will definitely take the Canon RF 28-70mm F2L USM, and if I really want to go crazy, I'll add the Canon RF 50mm F1.2L USM and RF 85mm F1.2L USM, which are stunning lenses in the line-up.

"If durability and battery life are my number one priorities, then the EOS-1D X Mark III is my first choice. But the 澳门现金网_申博信用网-官网5 and 澳门现金网_申博信用网-官网6 are very powerful cameras, especially taking into account the form factor and the weight. So if that's really beneficial, and if you're trying to be at the forefront of technology, choosing one of those two cameras is your best option."
