Read more: FUJINON GF45-100mm F4 R LM OIS WR review If you’re only going to pick one zoom lens for a GFX camera, this is probably the most appealing. Sharpness is fabulous throughout the entire zoom range, right into the corners, and there’s minimal colour fringing or distortion, all helped by the inclusion of three aspherical elements, one ED element and one Super ED element. Also like the GF32-64mm, the physical length of the lens extends at longer zoom settings but, even so, build quality, handling and performance are all of a fully professional-grade standard. The f/4 aperture rating might not sound very ‘fast’ but it’s pretty typical for medium-format zooms and does enable a reasonably tight depth of field, especially towards the long end of the zoom range. ![]() It’s naturally not so wide-angle but does stretch into telephoto territory, with an ‘effective’ overall zoom range of 36-79mm in regular full-frame terms. Read our full Fujifilm GF20-35mm F4 R WR reviewįor enhanced versatility, this lens covers an arguably more useful range than the companion GF32-64mm. Premium features make this lens even more desirable, like a Nano-GI coating to suppress lens flare and ghosting, a fluorine coating for stain resistance, and 12-point weather sealing for all-weather versatility. The front two groups in front of the aperture serve for both zooming and focusing. The number of elements traditionally needed has also been reduced by using an aspherical surface in each group. This is also surprisingly small and light for a lens of its type, using a near symmetrical lens element configuration to facilitate aberration correction. The GF20-35mm offers an effective focal length equivalent to a 16-28mm on a full-frame camera and has been designed to offer sufficient resolving power to take advantage of the 100-megapixel resolution of the GFX 100S. ![]() They don’t tend to be overly large, however, with modest aperture ratings that help to keep the size and weight down to manageable levels.ĭespite being a zoom lens, the GF20-35mm F4 R WR goes noticeably wider than the GF23mmF4 R LM WR prime, which had previously been the widest lens for a GFX camera. The lenses are typically quite chunky, because they need to deliver a bigger image circle than full-frame format lenses, to cover a relatively large medium-format image sensor. It’s the opposite with the GFX system, where a 50mm lens gives an ‘effective’ focal length of 40mm on a full-frame body. We’re generally more used to multiplying the focal lengths of X-mount APS-C format lenses by 1.5x to give the ‘effective’ focal length in full-frame terms, so a 50mm lens would be similar to using a 75mm on a full-frame camera. As such, GFX system lenses have a kind of 'inverse' crop factor or focal length multiplier of 0.79x. Then there’s the upsized Fujifilm GFX 100 and GFX 100S with their ultra-high 102 megapixel image sensors.Ī similarity of all GFX series cameras is that they have a 43.8x32.9mm image sensor, which is substantially larger than the 36x24mm sensor of ‘full-frame’ (35mm) cameras. ![]() It’s based on digital bodies that include the conventional-looking Fujifilm GFX 50S II and the relatively compact, rangefinder style GFX 50R, both of which have 51.4 megapixel image sensors. By 2024, our mission is to help a million Indians get the eye care they deserve.Fujifilm makes a wide range of high-quality, high-performance APS-C format X series cameras with interchangeable lenses, but leapfrogs the full-frame (35mm) sector altogether, moving straight on to the GFX medium format system. Our online efforts have a unique user-experience to ensure you get what you need easily and quickly. The Indian population doesn’t have the best access to eye-care, and so through our eye-camps, free eye-tests, and home-try on service, we’re bringing you the best of vision care and top-notch eyeglasses, sunglasses and contact lens right to you. We’re bringing a revolutionary change to the eyewear industry with the curated collection of high-quality lenses at affordable prices. Whether through our social initiatives to help the marginalized or through our eyewear retail stores we want to make sure that every Indian has a pair of eyeglasses best suited for their needs. Every Indian should have Chashma, whether prescription or non-prescription. ![]() CHASHMA, It’s Local – Designed in India Made in BharatĬhashma was founded on one simple thought-to bring the best of optical manufacturing, design, and technology to each and every Indian.
