What I would like to see released in 2024
Manufacturers are often accused of not listening to customers when it comes to introducing new features but I’m sure it’s complicated to strike a balance between what’s achievable and their users’ wishes. Nevertheless, it’s still odd that we haven’t seen some features that would appear to be easy to add, such as those via software or firmware updates. So, here’s a list of some firmware or software (via the maker’s app) features that I would like to see added to cameras this year: Auto aperture series selection, where the photographer can program the camera to select and capture a series across a range of aperture settings. The camera must alter…

Leica APO Summicron-SL 50mm F2 ASPH lens review
Announced on 15 August 2019, 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. But, it’s designed for a digital sensor so there are some prerequisites to satisfy. 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 well corrected optically.…

Leica APO-Summicron-SL 50mm F2 ASPH lens announced
Leica has announced the Leica APO-Summicron-SL 50mm F2 ASPH lens, an L-mount lens that’s not only compatible with the Leica SL currently but as a part of the L-Mount alliance, the lens is compatible with the Lumix S1 series made by Panasonic as well as the Sigma fp. The lens features 12 elements with three aspherical surfaces and an unknown number of elements – Leica claim as the ‘majority’ – being made of anomalous partial dispersion glass for apochromatic correction. As with other lenses in the Summicron-SL series, the 50mm F2 ASPH features a Dual Syncro Drive (DSD) stepping motor for fast autofocus, which allows for the lens to be driven…

Leica APO Summicron-SL 90mm F2 ASPH lens review: The best money can buy
All modern lenses perform well, especially short-tele primes like the Leica APO Summicron-SL 90mm F2 ASPH, but the sizes over the last couple of years have become enormous. Admittedly, this is due to the makers’ preoccupation with ultra-high-speed lenses but independents like Sigma and Zeiss aren’t holding back. It seems that size is no longer a barrier, but that’s strangely at odds with the trend in smaller mirrorless cameras. Even Leica, the maker of the original compact primes for the M-series, succumbed to that mindset with the first lenses for the Leica SL models Both the Summilux-SL 50mm F1.4 ASPH and the Vario-Elmarit 24-90mm F2.8-3.5 ASPH are optically outstanding. If you need lenses…
