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…

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…

    Leica Noctilux-M 35mm F1.2 ASPH announced

    January 29, 2026 / 0 Comments

    Leica has officially announced the Leica Noctilux-M 35mm F1.2 ASPH for Leica M cameras. The new lens has a high-speed maximum aperture of F1.2 and is the first in the Noctilux series to feature the 35mm focal length. It consists of 10 elements in five groups (which includes 3 aspherical elements and floating elements). It also features an appealing minimum focus distance of just 0.5m, yet retains the common 49 mm filter thread size, measures 50 mm (2 in) in length, and weighs 416 g (14.6 oz). The new lens will be available immediately for £7,700 inc VAT /$9,650. Summary: Maximum aperture: F1.2 Elements: 10 elements in 5 groups (including…

    ND Filter Factors, Densities and F-Stops compared

    January 26, 2026 / 0 Comments

    Numerous manufacturers use different terminology for their Neutral Density filters, which can sometimes make direct comparisons difficult. I’ve produced this chart showing the various designations in use against the number of stops reduced. Some manufacturers produce filters that fall in between stops, making comparisons even harder. For example, an ND400 filter would be just below 9 stops, but probably within tolerance to be marketed as a 9-stop filter. Those highlighted are the three most versatile filters overall, though it depends on your intended use. A 15-stop filter for long exposures in bright conditions, fully blurring clouds and smoothing seas, might be more useful than a 10-stop, which may only partially…

    Leica Summilux-M 50 F1.4 Classic (V2) lens review

    January 20, 2026 / Comments Off on Leica Summilux-M 50 F1.4 Classic (V2) lens review

    Leica recently launched a new version of its classic Summilux-M 50 F1.4 lens from 1959. Kevin Carter takes a look.   As the fifth in the Classic Line series, following the Summaron-M 28 F5.6, Thambar-M 90 F2.2, Noctilux-M 50 F1.2 ASPH, and the Summilux-M 35 F1.4, the newly reissued M-mount model features vintage Leica styling, including a scalloped focusing ring and chrome-plated brass construction. To complete the vintage aesthetic, there’s even a circular, “vented” hood in black with chrome locking buttons. Optically, the lens is based on the second Summilux-M 50 f/1.4 (II) formula, a design that promises highly attractive rendering, wide open, with soft blur transitions to out-of-focus highlights.…

    Leica M EV1 review: Electronic viewfinder model is a revelation

    November 27, 2025 / Comments Off on Leica M EV1 review: Electronic viewfinder model is a revelation

    What is it? The Leica M EV1 is a long-rumoured model based on the Leica M11 body and M-mount, but with an electronic viewfinder rather than an optical rangefinder. It’s a feature that’s been a long time coming, but now that it’s here, what is it really like? And does it really ‘work’ in place of the rangefinder? Key features Full-frame 60MP BSI-CMOS sensor with Triple Resolution Technology ( 60, 36 or 18 megapixels) 5.76 megapixel EVF Manual focus only, with focus peaking and focus assist (magnification) aids at taking aperture Supports Content Credentials 64 GB internal memory (and single SD slot) Connectivity via Bluetooth, Wi-Fi or cable Available from…

    Lightroom Classic: Best Practice for Keeping Edits Separate

    November 19, 2025 / Comments Off on Lightroom Classic: Best Practice for Keeping Edits Separate

    In Adobe Lightroom Classic, when you copy a Collection, the edits and adjustments made to images in the original Collection are also applied to the copied Collection. This means that changes made to a photo in either Collection will update in both. Unfortunately, there is no direct way to create a complete copy of the Collection that maintains separate edits from the original image directly within Lightroom. However, there is a way to work around that by creating a Collection from another Collection. 1. Create Virtual Copies Right-click on the image you want to edit and select “Create Virtual Copy.” Virtual Copies let you make different edits to the same…
