Canon's 5D Mark IV is a top performer - but you'll be paying a premium for it. Top-notch images are promised from this camera, which will be all too familiar to existing users of the 5D Mark III or 5D Mark II .

Full-frame sensor; Touchscreen is useful; Solid 4K video recording; Built-in Wi-Fi

Heavy; Expensive; Frame rate isn't particularly high

My expectations were that the Canon EOS 5D Mark IV was going to be at least as wildly successful as its predecessors were, but that expectation was not very hard to realize. The Canon EOS 5-series cameras have become synonymous with value and versatility.

The fourth version of the highly successful Canon EOS 5D, the Canon EOS 5D Mark IV is now available, and the latest version introduces a number of new features, including a new 30 megapixel full-frame sensor made by Canon, 7fps continuous shooting, 4K video recording, plus built-in GPS and Wi-Fi.

7fps continuous shooting; 30 megapixel FF sensor; Excellent colour and white balance performance; Dual Pixel Raw optimizer can help with some scenes; 3.2 inch touch-screen; 4K CINE video recording; Very good noise performance; Impressive focus speeds

This is a MACHINE. The touchscreen is amazing with all the controls there. The image quality is superb. High ISO is great. ISO 12,800 and even 16,000 totally usable. I have hardly delved into the touchscreen use but a friend did and he loves loves loves it.

Great image; touch screen rocks; Price reasonable for what you are getting

support software is lagging behind because it is so new; To Canon I suggest rather than make software reverse engineer just give them the specs up front so they can launch with the product; It will make your launch better. The battery grip for 2 batteries is way too expensive.

The EOS 5D series has played a major role in Canon's EOS line-up for more than a decade. Over the past 11 years we've seen no fewer than six DSLRs adorn the EOS 5D logo, but it was the original EOS 5D back in 2005 that will be remembered as the DSLR that made full-frame photography viable to...

Genuine improvements like touchscreen control; Dual pixel RAW is incredible (when it works); Fantastic video and still photo quality;

New features mean a higher debut price; Some bugs to iron out in dual pixel RAW;

If there's one thing advanced enthusiasts and pro photographers are going to lust after this year, the 5D Mark IV is it. And with good reason: It's not necessarily an all-singing, all-dancing model, but what it does, it does extremely well.

With the EOS 5D Mark IV, Canon has further refined its semi-professional full frame all-rounder. With a solid build and improved weather sealing, faster burst speed, increased resolution, increased dynamic range, updated autofocus system and Dual Pixel live view functionality, the Mark IV will be as...

Built around a new 30.4Mp full- frame CMOS sensor, capturing 6720 x 4480 pixel stills in 3:2 aspect ratio, the 5D Mark IV offers a notable increase in resolution over the 22.3Mp 5D Mark III .

Canon's 5D line of cameras is one of the most universal on the market. Traditionally, the Canon 5D has offered professional grade performance at a price that is accessible to committed hobbyists.
