Source has published the slides from the recent press conference of Sony, which the manufacturer recalled that the E-mount was originally designed for full-frame mirrorless cameras. Although the first model, introduced in 2010, was APS-C, even then, the manufacturer talked about the technical feasibility of the production of full-frame cameras with such a mount.

Sony утверждает, что теоретически может сделать для камер с креплением E объектив с максимальной диафрагмой f/0,63

Options attachment E allow the theory to create a lens with a maximum aperture of f/0,63.

Note that this is also the theoretical limit of the maximum aperture if you mount Leica L, which have agreed to use in their products, Leica, Panasonic and Sigma. Mount Canon RF theoretically allows to create a lens with a maximum aperture of f/0.62 and an unattainable record for this parameter is a Nikon-mount Z. Recall that we are talking about mounting lenses on full frame mirrorless cameras.

Of course, Sony will never make a lens with a maximum aperture of f/0,63 like a Nikon lens with a maximum aperture of f/0,58. However, for example, the issue of lens Z Nikkor 58mm f/0.95 Noct’s included in the plans Nikon for the current year.

Note that in absolute terms, the sensor is good. At the base sensitivity of ISO 100 camera Canon EOS R covers a dynamic range of 13.5 EV. However, sensors with back-illuminated to be used in Nikon Z-6 and Sony A7 III is still 1 EV wider. Although other values of the advantage is smaller, it remains practically in the whole range of sensitivities. In some situations it might be noticeable, since a wide dynamic range not only allows you to simultaneously capture details in bright and dark areas of the frame, but gives greater headroom for the correction of inaccurate exposure when processing. Moreover, noise sensor Canon EOS R too inferior to competitors.

Overall assessment of Canon EOS sensor R is equal to 89 points. For comparison, the Nikon sensor Z 6 scored 95 points, Sony A7III — 96 points.

In September last year, the company Panasonic has announced the development of DG lens Leica Vario-Summilux 10-25 mm f/1.7 Micro Four Thirds system. Keeping a constant maximum aperture of f/1.7 in the range of 20-50 mm of EFR, it will be the most high-aperture wide-angle zoom lens of this system. The deadline for the release of novelties is still unknown, but the manufacturer has managed to show its prototype at the exhibition CP+ earlier this month.

Source has published a new image of the product. Pictures were taken at the exhibition Photography Show in Birmingham 2019. In contrast to the CP+, the lens stood at the window, this time it was possible to hold in your hands. And in some pictures it is mounted on the camera.
