Filter sizes for Leica M lenses
As you might expect, Leica offers its range of UV filters, which are recommended for the protection of the front element in everyday use but also to prevent damage when cleaning. It’s much less worrying to clean a filter than a front element. However, I also recommend B+W (UV or Clear) filters, which, although made by the German brand Schneider-Kreuznach, tend to be slightly cheaper and yet are not considered inferior in any way. The XS-Pro, now replaced by the ‘Master’, features a thin brass frame and a Nano coating to facilitate easier cleaning. More competitively priced offerings include the excellent Breakthrough Photography UV X2 range and the Firecrest series…

Recomended Filters for Lens Protection
Filters for lens protection seem to divide opinions; however, I’m strongly in favour of them. Not only do they prevent fumbling with lens caps (keep those for storage), but they’re also a lot easier to clean than the front element. I also don’t like cleaning lenses and would rather accidentally scratch a filter than my lens. And if you think it’s unlikely, consider the number of secondhand lenses for sale on eBay with scratched front elements. Those few that aren’t sell for appreciably more. Fingerprints are another issue. They are both greasy and contain an acid that damages coatings, and so should be removed promptly. My filter of choice for…

Filter sizes for Fujinon GF lenses
When reviewing the Fujinon lenses, Fujifilm UK always send out samples with Fujinon Protector Filters, and I’ve been impressed with the way they handle flare and ghosting. Filters for lens protection seem to divide opinions; however, I’m strongly in favour of them. Not only do they prevent fumbling with lens caps (keep those for storage), but they’re also a lot easier to clean than the front element. The following is a work in progress, so the columns will be filled out in due course. Fujifilm doesn’t specify the pouches in their lens manuals or websites.

Filter sizes for Canon EF lenses
Canon filter sizes are difficult to find, at least in a list form. At one time, all manufacturers went to the trouble to do so with printed brochures but now, with the internet, not so much. With the move to EOS R cameras and the highly capable and versatile EF-RF adaptors, the older EF lenses remain hugely popular. Indeed, with focusing accuracy as good if not better than the older DSLRs, especially when focused off-centre, EF lenses have seen a new lease of life. Filters for lens protection seem to divide opinions, however, I’m strongly in favour of them. Not only do they prevent fumbling with lens caps (keep those…

Filter sizes for Canon RF lenses
Manufacturers have favourite filter sizes. Canon, for example, often adopted 72mm and 77mm for L-series EF mount lenses but that has changed somewhat with the RF mount to 67mm, 77mm and 82mm being common sizes. Once a popular size on the original Canon FD breach-lock mount lenses from the 70s (not FDn), the 55mm filter thread size is also making a comeback. For Canon lenses, I recommend Canon ‘Protect’ or Protector filters as they’re extremely high quality. They’re also very reasonably priced, at least for the popular sizes. Sizes above 82mm are steep, though, so you could look for more competitive offerings such as the excellent Firecrest models for that…

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 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…

Sigma 105mm F1.4 DG HSM Art lens review: Outstanding performer
The Sigma 105mm F1.4 DG HSM Art debuted earlier in the year, around May, and is priced at around $1400/£1500. From the DG designation, you can tell that it’s a full-frame lens, and it’s available in Canon, Nikon and Sigma mounts. It is of course, targeting the superb but pricey Nikon AF-S Nikkor 105mm F1.4E ED, but would also appeal to Canon users, where a high-speed L-series model in that focal length is strangely absent from the line-up. It may also be possible that it becomes available in the Sony FE mount; it is already suitable for mirrorless cameras. Sigma has recently introduced some Art series in Sony FE mount,…

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.
