PERFORMANCE: EXPOSURE LATITUDE

shooting too sensitive and I took more than a few shots of the ground, my boots and the sky just by brushing the monitor. Adjusting the touch sensitivity didn ’ t help but the good news is that the camera can be set to have touch control without touch shooting so you can have the best of both worlds. For street shooting in live view I did have touch AF/shoot and face detection active together with the silent shutter and that set-up worked nicely. Press the Q button and that brings up the quick menu . If you like to tailor a camera’s functions and features to your way of working, the EOS 90D does give you that opportunity, although not quite as extensively as the leading mirrorless models. Nevertheless, the depth-of-field preview button has nine options, the exposure lock ten and the set button 18, so plenty of choice. The camera delivered a consistently good performance and produced very fine Raws and out-of-camera JPEGs. The 32.5-megapixel sensor meant 58.9x39cm (or 23x15.5in in old THE CAMERA DELIVERED A CONSISTENTLY GOOD PERFORMANCE AND PRODUCED VERY FINE RAWS AND OUT-OF- CAMERA JPEGS ABOVE The EOS 90D proved to be a very user-friendly DSLR capable of excellent quality images thanks to Canon’s new 32.5-megapixel sensor

The scene was manually metered at 1/100sec at f/11 with the EOS 90D in its evaluative measuring mode, and then exposure bracketed in 1EV intervals up to +/-3EV. The originals all started life as Raw files and exposure corrected in Adobe Lightroom. Overexposing by +1EV and +2EV gave Raws with good potential for full recovery with minimal editing work – there could be a colour shift with the +2EV files. Depending on the scene, with strong lighting +3EV was about the limit and highlight areas looked grey and flat. In scenes of lower contrast, though, +3EV files could be recovered okay with some colour adjustment so this isn’t a bad showing from the sensor. There was a good showing from underexposed shots too and -3EV and even -4EV shots

pass filter, installed to help defeat moire and false colours. Either way, there is probably even more quality potential in this high-resolution sensor. The high pixel count gives the ability to crop in for a decent subject size with minimal pixellation. When shooting subjects like action and nature, even a long lens still might not be enough for a good subject size so this is a welcome opportunity. High-contrast scenes were also handled well and the Raws
money) files at 300ppi with no software interpolation and I got some lovely prints with the supplied EF-S 18-55mm f/3.5-5.6 lens. That said, I wondered if I would get even better shots with higher spec optics, because images shot with this lens even on a tripod at f/11 lacked sparkle, and fine detail seemed to lack bite. Of course this might simply be because this lens is not good enough for the higher resolution sensor or it might be due to the sensor’s optical low
looked fine in terms of tonality and saturation. The penalty was noise though. In the -3EV there was a level of noise in areas of even tone that made an ISO 100 shot look like it was exposed at ISO 1600. The noise level dropped significantly at -2EV and fell again at -1EV so that the latter looked the same as the correctly exposed shot.
