The Canon 5D family, which is one of the most well-known series of camera bodies, has seen the release of the newest model over four years after the 5D MKIII, and it's loaded with some much wanted and needed improvements.

The Canon EOS 5D Mark IV ($3,499, body only) is the company's latest mainstream pro SLR . For the most part it looks and handles like its predecessor, the 5D Mark III , a plus for veteran photographers who know their camera by heart.

30MP full-frame image sensor; Fast 61-point autofocus system; 7fps continuous shooting; Unlimited JPG shooting buffer; Pro-grade build; Dual Pixel AF Live View focus system; 3.2-inch touch screen; Integrated GPS and Wi-Fi; CF and SD card slots

Cropped 4K video; Clean HDMI output is 1080p only; Dual Pixel Raw function slows camera and offers limited benefits; 4K video files are quite large; Omits in-body flash

Great camera overall, I have a 5DM3 and the controls are quite similar so no learning curve to speak of. I really appreciate being able to zoom in on the touch screen and especially love the wifi feature which is very useful where I'm official photographer at dog shows, and also for portrait...

The Canon EOS 5D Mark IV is a new professional digital SLR camera. The 5D Mark IV features a 30.4 megapixel CMOS sensor, 7fps continuous shooting with full AF/AE tracking, internal 4K movie recording (4096 x 2160pixels) at 30/25/24 fps and 8.8 megapixel in-camera 4K still frame grab, an expandable...

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

Screen doesn't tilt; Price of new model; Competition offers higher resolution

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...

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.

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
