Canon RF 35mm F1.4 L VCM lens review
Key features Highly versatile 35mm focal length Stills/video hybrid VCM for smooth focusing Nano USM for floating element control Floating element design to reduce aberrations at close range Breathing correction SSC and ASC coatings reduce lens flare, and ghosting Aperture/iris collar for video 11 aperture blades Custom function button What is it? The Canon RF 35mm F1.4L VCM is a high-speed, stills and video-oriented semi-wide-angle lens designed for the EOS R range of mirrorless cameras. It’s the successor to the much-vaunted EF 35mm F1.4L USM II, only it’s not quite what we were expecting. Like the Canon RF 24-105mm F2.8L, this lens is a hybrid model that appeals to both…

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…

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…
