Leica Super-APO-Summicron-SL 21 mm F2 ASPH lens review
The Leica Super-APO-Summicron-SL 21 mm F2 ASPH is a high-speed wide-angle for Leica SL cameras. It was announced in October 2023. This lens has the Super-Apo moniker and has a complex design of 14 elements in total, arranged in 11 groups. Leica doesn’t say how many AD (anomalous partial dispersion) elements there are but claims that ‘most’ of the 14 elements are made from ‘special custom glass.’ That may include the three elements with aspherical surfaces, but it’s unclear. Like others in the SL range, the lens also adopts a ‘digital element,’ or what’s better known as a built-in profile, to correct vignetting, distortion and chromatic aberration. While it’s perhaps…
Leica SL3 review
The Leica SL3 is the third in the series of mirrorless models, which started with the magnificently minimalist 24 MP Leica SL. I take a look at what’s changed and why you should buy it. What is it? The SL3 is the latest in the series and adopts the same body style as the 47 MP Leica SL2 and the 5-axis IS from that model, which was missing from the original SL. The headline specs are the increase in sensor resolution to 60 MP and the inclusion of hybrid AF with Depth from Defocus (DFD) tech to aid focusing accuracy. Fortunately, the photographer doesn’t need to know how this works,…
Leica APO Summicron-SL 50mm F2 ASPH lens review
Announced on 15 August 2019 (see our coverage here), the Leica APO Summicron-SL 50mm F2 ASPH is a relatively compact high-end lens for Leica SL cameras. Inside, the lens design is complex for a 50mm. However, it’s designed for a digital sensor, so some prerequisites must be met. It has no less than 12 elements in total, with several AD (anomalous dispersion) elements to mitigate CA and fringing, plus three with aspherical surfaces to reduce SA and distortion. The lens also adopts what some call a “digital element,” or a lens profile, to correct vignetting, distortion and CA, more as an afterthought in this case, as the lens is so…
Leica SL3 camera announced
Leica has announced the Leica SL3, the latest top-of-the-range model in the 35mm full-frame SL system. This is an exciting new camera for Leica and a hugely compelling update to the SL2, however, keen-eyed readers will see that there’s no multi-shot function, which was one of the key features of the SL2 (and SL2-S), or at least a key-differentiator between it and rivals (who haven’t yet matched Leica/Panasonic in either implementation or result). I spoke with a Leica executive and they informed me that the multi-shot feature has not been included this time but if there is strong demand for it then they will consider adding it at a later…
