The adapter uses an optical design consisting of five elements in three groups to multiply the focal length and F-stop of Canon EF-mount lenses by 1.26x to match the image circle of EF lenses to Fujifilm’s GFX cameras while retaining the same diagonal field-of-view. Canon calls this the Canon Lens RF24mm f/1.8 MACRO IS STM: RF: Works only on Canon's EOS-R Mirrorless cameras. MACRO: Focuses to half life-size. IS: Image Stabilization. STM: STepper (autofocus) Motor. Optics specifications top. Canon RF 24mm f/1.8 internal optical construction. UD and Aspherical elements. IS section. The newly patented lenses, spotted by Canon Watch, comprise three versions of a Canon RF 24mm – two f/1.4L variants (with only a 0.79mm difference in backfocus between them) and an f/1.8 option. Then there are the 28mm f/1.8, 35mm f/1.8 and 50mm f/1.4. There is an established tradition of releasing prime lenses in various aperture ranges Still, in some tripod-based testing, the Canon EF 85mm f/1.4L IS USM Lens turned in nearly perfect f/1.4 results using the center AF point and not far from perfect when using peripheral points. Focus accuracy decreased modestly with more complicated subjects, but was still good overall. With a classic ‘effective’ focal length of 85mm on APS-C format Fujifilm X, Nikon Z and Sony E mirrorless system cameras (90mm on Canon EOS M bodies) this Viltrox lens is a prime candidate for portraiture. That’s reinforced by its fast f/1.4 aperture rating, enabling a tight depth of field. It’s as sharp as you like with lovely soft bokeh.

John Riley reviews the Canon EF 85mm f/1.4L IS USM, a bright prime lens ideal for portraits using Canon full-frame cameras. Used Canon EF 24-70mm f/2.8 L II USM. Heavily Used £609. The EF 24mm f/1.4L II USM is designed to withstand the rigours of even the most testing shooting environment – with Canon’s advanced weather and dust sealing making it the perfect choice for photojournalists and landscape photographers. EF 24mm f/1.4L II USM lens specifications p.1 #8 · p.1 #8 · 24mm 1.4 for Astrophotography. Many lens designers don't even consider coma in their designs, because for almost anything other than astrophotography, it doesn't really matter much. Rokinon (Samyang) lenses tend to perform well with respect to coma, which makes me think they design for it. The build quality of the EF 24mm f/1.4 USM L II is simply superb and the new weather sealing is reassuring when shooting in very harsh conditions. The AF is very fast and near silent. All-in-all it's a very good lens if you're aware of its potential and limitations. Optical Quality: The EF 50mm f/1.8 ($125.00 at Amazon) is a small, light lens. It measures 1.6 by 2.7 inches (HD), weighs just 5.7 ounces, and supports 49mm front filters. Canon doesn't include a lens hood, but The Sigma 24 mm f/1.4 Art is about as heavy (665 grams vs 650 grams), just as solidly built and perfectly finished as the famous Sigma 35 mm f/1.4 Art and Sigma 50 mm f/1.4 Art. The store price of the Sigma 24 mm f/1.4 Art may be hundreds of euros lower than the store price of the Canon 24 mm f/1.4 L II, but it can’t be seen in the build quality.
