Performance: exposure latitude
To test the exposure latitude of the EOS RP’s Raws, a sunny Venice was the setting for this exposure bracket shot with the RF 24-105mm f/4 lens mounted on the EOS RP. The metered correct exposure was 1/200sec at f/11 and ISO 100. Exposure correction was done in the latest version of CanonDigitalPhotoProfessional software. The software has a +/- 3EV correction limit. Tonally, the underexposed files fared best, although in the case of the -3EV and -2EV shots, noise was evident, especially in
areas of even tone. The -1EV and correctly exposed shots looked the same. Overexposure is less kind. The +1EV Raw recovered well, but the +2EV shot has cyan highlights – and this was even more evident with the +3EV shot, so it looked rather anaemic. The same level of overexposure to Raws shot in dull light were recovered much more successfully. Overall, though, the Raws from the EOS RP responded reasonably to exposure abuse and recovered well.

AF point with my nose. I tried both touch sensitivity settings, but that didn’t help. The touch sensitivity area can be altered, though, and making only the left-side of the screen touch sensitive helped, but I still had issues. In the end, for focus point changing I used the four-way pad. The default way of moving the AF point around is pushing the AF selection button and then using the four-way pad, so this was a two- stage process. A custom function gives direct control with the four- way pad and this was OK, although the single AF point did not move very quickly around the screen. The EOS RP has the usual Canon selection of zone, face detect and wide AF zone options, too. I mostly stuck with single point or AF four- point expansion. The wide zone face detect mode worked reasonably well, but did not prove reliable. I took the EOS RP to a music gig and when going for a wide shot with the three guitarists in the frame, the face detect consistently picked up on in the dimly lit guy on the far left, where I expected the AF algorithm to logically go for the brightly lit lead singer, dead centre of the frame. That’s why I stick with single point or small zone AF and here the EOS

Above The Canon EOS RP comes with the EF-EOS Rmount adapter which enables EF and EF-S lenses to be used with full compatiblity. We tried the EF 24-70mm f/4 (left) with the EF-EOS R and AF was impressively swift in a wide range of lighting situations.
RP did well with swift, accurate AF, even in bad lighting. On the EOS R, we saw the first appearance of the menu function swipe bar – which is not on the EOS RP – and you can’t help but get the feeling that Canon is trying out some new controls as a live experiment. If they arewell received, no doubt we’ll see them on forthcoming models. I was so frustrated with the EOS

Images For the exposure latitude test, the exposure was 1/200sec at f/11, ISO 100. The Canon EOS RP Raws coped with underexposure better than overexposure, with the +3EV looking a little anaemic. Overall, the camera handled the exposure abuse well
