Canon EOS 850D

OUR VERDICT

If you're looking to step up from a camera phone to explore more creative stills photography with a 'proper' camera, the Canon EOS 850D is a lightweight yet powerful DSLR that captures detailed, colorful images. Its improvements over the 800D are subtle though, as both have 24Mp sensors, 45 cross-type AF points, 6/7fps burst shooting, and WiFi. The 850D's headline new feature – 4K video recording – sounds great, but Canon is only playing catch-up with existing 4K-capable mirrorless cameras in the same sector. Plus, with up to a huge 64% crop factor and no phase-detect AF available, the 850D's implementation of 4K video is nowhere near as useful as you'd hope.

Canon is keen to offer photographers easier ways to share images online, so the EOS 850D includes 2.4GHz Wi-Fi and Bluetooth Low Energy so you can connect to your iOS or Android device through the Canon Camera Connect app to edit and share high-quality images. From there, content can be downloaded to a smart device, reviewed and posted on social media or shared with friends and family.

The Canon EOS 850D  is a lightweight, versatile and connected DSLR, powered by Canon’s fast DIGIC 8 processor and is capable of 7fps continuous shooting. It has Canon’s tried and tested 24.1-megapixel Dual Pixel CMOS APS-C sensor, but what sets the 850D apart from the old 800D is its Intelligent Tracking (iTR) autofocus technology, and of course, its new 4K movie capability. However, it's worth noting that while 4K may be new to Canon DSLRs at this price point, mirrorless cameras in the sector have been 4K-capable for at least one camera generation already.

iTR AF aims to improve focusing when using Face Tracking AF and the new Eye Detection AF in Live View, to help you take better portraits with sharper eyes to bring your subjects to life.

While shooting ‘traditionally’ using the optical viewfinder (that shows 95% coverage) the autofocus tracking on the 850D benefits from 45-point all cross-type AF, as well as Canon's Dual Pixel CMOS AF.

The 850D's body design is compact but comes with top and rear dials for dual control of both shutter speed and aperture. As part of Canon’s EOS system, you can use any EF or EF-S lens, and you can add a Speedlite flashgun for more creative lighting than the built-in pop-up flash can provide.

Naturally for a camera in this sector, it can shoot uncompressed RAW files, to give you more control when editing your images, but there's also a C-RAW format that'll produce smaller file sizes that almost doubles the continuous shooting buffer from 40 images to 75.

As far as movie recording is concerned, the camera can record in Full HD at up to 60 fps, or 4K UHD resolution at up to 25 fps. There's also a detailed set-up for time-lapse movies and automatic scene selection. To counteract the ‘jittery shake’ associated with handheld movie shooting, the 850D features 5-Axis Movie Digital IS, for smooth, controlled video capture.

The 850D is available body-only, or with the Canon's decent EF-S 18-55mm f/4-5.6 IS STM kit lens, which gives you a focal range versatile enough for you to capture everything from wide-angle landscapes to portraits.
