Just like the EOS 80D that’s positioned above it in Canon’s enthusiast line-up, the EOS 77D is equipped with a 24.2MP APS-C CMOS sensor. Although this sensor doesn’t offer a higher pixel count like the EOS 760D did over the older EOS 700D, it does support Canon’s Dual Pixel AF technology that promises considerably faster focus acquisition in live view.
As well as this notable enhancement, the EOS 77D’s sensor pairs up with Canon’s most up-to-date DIGIC 7 image processor that’s claimed to process data 14x faster than the DIGIC 6 processor found within the EOS 750D/760D. This has resulted in the camera offering a higher maximum burst speed and superior buffer depth. Whereas the EOS 760D could shoot at up to 5fps for as many as 940 JPEGs or eight RAW files, the EOS 77D claims to be capable of recording an unlimited number of JPEGs at 6fps or 27 RAW files at the same speed.
In addition to these speed benefits, the new sensor and processor pairing also allows the EOS 77D to shoot at a higher maximum native sensitivity setting of ISO 25,600 (along with the equivalent of ISO 51,200 in expanded mode). By comparison, the 750D/760D both offer a maximum native sensitivity setting of ISO 12,800, with the equivalent of ISO 25,600 available in its expanded mode.
The EOS 77D’s new AF system is a far cry from the 19-point autofocus system that featured on the EOS 760D. The major revamp has seen it inherit the same 45-point all-cross-type AF system from the EOS 80D. Out of the 45 AF points on offer, 27 remain active when using a teleconverter and lens combination with a maximum aperture of f/8, whereas the centre point is sensitive down to f/2.8.
The good news doesn’t end here. The working range of the AF system also spans wider than it did before, and operates across a -3EV to 18EV range.
At this point, you might be wondering how the EOS 77D differs from the EOS 80D. Viewing the EOS 77D from above reveals that its top-plate LCD is smaller and more cramped.
Turning to the rear, the pentamirror viewfinder, with its 95% coverage of the frame and 0.82x magnification, doesn’t quite trump the 100% frame coverage and 0.9x magnification of the EOS 80D’s pentaprism. Neither does its battery offer the same stamina.
Whereas the EOS 80D can shoot 960 shots on a single charge, the EOS 77D’s smaller LP-E17 battery lasts for about 600 shots.
There are other differences, too, with the 80D shooting a continuous burst 1fps faster and presenting a higher maximum shutter speed (1/8000sec as opposed to the EOS 77D’s 1/4000sec).
Below the EOS 77D’s viewfinder you get a 3in, 1.04-million-dot, vari-angle touchscreen, with metering left in the capable hands of Canon’s 7,560-pixel RGB IR metering sensor – yet another feature it inherits from the EOS 80D.
The EOS 77D doesn’t feature 4K video, but provides videographers with the option of shooting Full HD (1920×1080) movies up to 60p in the MP4 format. By way of comparison, the highest video setting on the 760D is 1080p Full HD at 30fps.
Even more impressive is the EOS 77D’s introduction of in-camera electronic image stabilisation. This is applicable only to movie recording and cannot be used for still-image capture, but it can be activated to ensure smoother video capture when shooting handheld.
Just like the EOS 800D, the EOS 77D sports a 3.5mm microphone port in addition to the twin stereo microphones either side of the pop-up flash. However, you’ll want to look at the EOS 80D if a headphone socket to monitor audio is a priority.
To satisfy those who would like to control the camera wirelessly and share images via a mobile device, the EOS 77D is Wi-Fi and NFC equipped. The camera’s wireless connectivity teams up with Canon’s Camera Connect app that’s free to download via the App Store for iOS devices or Google Play for Android.
In addition, the camera offers constant Bluetooth wireless control, which ties in with a new BR-E1 remote controller (£39) that can fire the shutter with no line of sight from 5m away.
