![]() ![]() So why has it taken so long for major brands like Nikon and Canon to adopt full-frame mirrorless cameras? There might be strategic motives, but there are also a few technological reasons. ![]() (There’s built-in Wi-Fi to let you do so on the connected smartphone if you want, though.) Why has it taken so long? The new M10-D doesn’t have a screen on its back, so you can’t review images on the camera. The company even seems to be trying to recreate the experience of shooting film with a digital camera. Of course, Leica hasn’t gone as far as putting an EVF in an M camera yet, but you can buy an external one for the M10, the M10-P, and the M10-D. You can preview many camera settings in the EVF. The technology exists, however, and it should only be a question of time before it makes its way onto mirrorless models. Global shutters are already commonplace in high-end smartphones, but are not yet found on full-frame mirrorless cameras. They also allow for easier flash-syncing, and eliminate the jello effect during video recording. Global shutters do away with these issues and would therefore reduce the need for a mechanical shutter. But ERS has some disadvantages, too: since the sensor captures the image line by line, images of moving subjects can show deformation and light-banding under certain light sources. Global shuttersĬurrent mirrorless cameras use a combination of mechanical shutters and electronic rolling shutters ( ERS), with the latter used for silent shooting or when shutter speeds are required that are not offered by the mechanical shutter. This means you can take photographs with a mirrorless camera in places like the tee of a golf tournament, where a DSLR’s shutter sound would disturb the players. ![]() Thanks to electronic shutters, many mirrorless cameras can also shoot completely silently. This type of “real-time” stacking is already widely implemented in high-end smartphones, but is not yet available in the current generation of mirrorless cameras. In real terms, this means that multi-frame stacking features, such as High Dynamic Range ( HDR), Temporal Noise Reduction (TNR), and focus stacking, can stack and merge frames that were captured before, during, and after pressing the shutter, achieving better results. With buffering technologies similar to the ones already used in some smartphones, even negative shutter lag is possible-that is, the camera records images even before the photographer presses the shutter button. In combination with an electronic shutter, no mirror also means that cameras can achieve true zero shutter lag. Without mirror vibrations, it’s also less complicated to design an efficient optical image stabilization system ( OIS), as it’s a lot easier to compensate for low-frequency motion (such as hand shake) than the high-frequency vibration a mirror would produce. No mirror vibrationįor a start, mirrorless cameras obviously have no mirror vibration, reducing the risk of camera shake and blur during longer exposures. Camera manufacturers are not yet exploiting all of these advantages, but over time we should expect to see all the features and functions described below in production models. With mirrorless full-frame cameras clearly on the rise, it makes sense to have a look at the advantages they offer over their DSLR equivalents, as well as the challenges the concept can create for camera engineers. The lack of a mirror is the most obvious difference between a mirrorless camera and a DSLR, and this brings with it a number of advantages. Mirrorless full-frame cameras - advantages and challenges They all use the same 24Mp full-frame sensor, but a new mechanical shutter mechanism means the latest incarnations are close to silent in operation. It recently introduced two new versions of the M10 digital rangefinder, the M10-P and M10-D. ![]() The competition should also help keep prices down and drive innovation.Īnd let’s not forget that Leica is also in the full-frame mirrorless camera market. That’s great news for photographers, as they now have a choice of lens mounts, handling, and interface. However, recent arrivals from Canon in the form of the EOS R, and from Nikon in the forms of the Z6 and Z7, plus two new full-frame cameras set to come from Panasonic in early 2019, mean that Sony will no longer have the full-frame mirrorless camera market to itself. That’s no mean feat, given how Canon and Nikon had dominated the market. And it has done incredibly well, even claiming the number one spot for sales of full-frame cameras of any design. Sony launched its Alpha 7 series in October 2013, and for the last 5 years, it’s really been the only major player in the full- frame mirrorless camera market. ![]()
