Press release: SIGMA 35mm F1.4 DG DN The evolution of a classic The 35mm F1.4 Art is reborn Exceptional optical performance Fast and quiet AF in a compact body Professional feature-set Superb optical performance and usability power up the most popular focal length. An "Art F1.4 35mm" reborn for mirrorless and empowered through SIGMA's technology to date. The existing 35mm F1.4 DG HSM | Art was SIGMA’s first GLOBAL VISION lens. Released in 2012, it set the standard for all of SIGMA’s subsequent Art-line lenses, and thanks to its exceptional image quality it is still the 35mm prime lens of choice for many professional photographers. Nine years on, the 35mm F1.4 has been redesigned from the ground up specifically for mirrorless cameras, and is the culmination of much of the optical design expertise and advanced production techniques gained over the past decade of GLOBAL VISION lens development. As with all of SIGMA’s lenses, the 35mm F1.4 DG DN | Art is built entirely at its sole factory in Aizu in Japan, where the standard of craftsmanship is of the highest level. As is true with all SIGMA lenses, class-leading optics are right at the heart of the design concept of this new 35mm F1.4 DG DN | Art. Despite being significantly smaller and lighter than the existing 35mm F1.4, it displays an outstanding level of sharpness right to the edges of the frame at all apertures, as well as exceptionally smooth and attractive bokeh and remarkably well-controlled optical aberrations. Designed exclusively for use with mirrorless cameras, the 35mm F1.4 DG DN | Art is light enough to feel perfectly balanced on a compact mirrorless camera, yet is packed with an array of professional features including ultra-fast AF, a de-clickable and lockable aperture ring and a customizable AFL button. This gives the lens operability and portability without compromise, making it as ideal for professional projects as it is for casual outings, and as well-suited to video as it is stills. SIGMA is delighted to introduce you to the new gold standard in wide-aperture 35mm primes. Key features 1. Exceptional optical performance Central to the design of the 35mm F1.4 DG DN | Art is its sophisticated optical performance, which is consistent with the development of all Art line lenses. The lens incorporates 15 elements in 11 groups. With two Special Low Dispersion (SLD) elements, an Extraordinary Low Dispersion (ELD) element, an ‘F’ Low Dispersion (FLD) element and two aspherical elements, and as well as other high-performance glass, the lens’ advanced optical construction utilizes SIGMA’s state-of-the-art optical design technology, minimizing all types of aberration including axial chromatic aberration, which cannot be corrected in-camera. In spite of having a very wide aperture of F1.4, the lens is able to control sagittal coma flare extremely well even wide open, stopping bright points of light from flaring out near the edges of the frame. This will be particularly appealing to night sky photographers. Owing to its 11 rounded diaphragm blades, the lens displays smooth, round bokeh so that out-of-focus areas are not distracting. This makes the 35mm F1.4 DG DN | Art well-suited to portraits, supported by its ultra-sharp image quality and minimal color bleeding. It also performs very well in backlit conditions thanks to SIGMA's anti-ghosting and anti-flare technology that it has cultivated through countless simulations and real-life testing in our many years of lens development. This keeps shots high contrast and free of excessive flare even when working in difficult light. 2. Fast and quiet AF in a compact body The focusing mechanism in the SIGMA 35mm F1.4 DG DN | Art features a stepping motor. This motor controls a focusing lens group composed of a single, lightweight element, which means AF is responsive and quiet, and is able to keep track of moving objects very effectively. Manual focusing is smooth and precise, but with the right amount of resistance for film-makers. Certainly, this lens has a focus mode switch on the body. The SIGMA 35mm F1.4 DG DN | Art wholly embraces the Art line concept, which is “designed with a focus on sophisticated optical performance”. This—paired with its advanced autofocus performance and the convenience of a compact size—makes for a lens that raises the standards. 3, Professional feature-set On the body of the SIGMA 35mm F1.4 DG DN | Art is an aperture ring that allows aperture to be controlled via the lens, or when set to Auto, using the camera. An aperture lock switch on the lens body allows the aperture ring to be locked in Auto so that it’s not accidentally knocked during shooting. A big plus for film-makers, the aperture ring can be de-clicked, allowing users to seamlessly adjust exposure. Also on the lens barrel is a focus mode switch and an AFL button, which can be customized to a desired function from within the camera menu (depending on the model). The switch is ergonomically positioned to be controlled by the thumb during use. A petal type lens hood is included in the box, which helps reduce flare and offers the lens added protection if dropped. The hood has a lock mechanism that keeps it attached securely to the lens, and its rubberized grip makes it quick and easy to attach and remove. On top of this impressive array of features and elegant exterior, the body of the 35mm F1.4 DG DN | Art offers an exceptional level of durability that helps it withstand long-term professional use as well as individual operating parts that give a good fit to the hand. The dust and splash proof structure provides sealing on buttons and along joins between constituent parts, and there’s a rubber gasket around the mount. There’s also a water and oil repellent coating applied to the front element ensures that photographers can rely on it in any conditions. Additional features Lens construction: 15 elements in 11 groups, with 1 FLD, 1 ELD, 2 SLD and 2 aspherical elements Internal focusing Compatible with high-speed autofocus Stepping motor Compatible with lens-based optical correction * Function available on supported cameras only.

Tamron has announced a new ultra-telephoto lens with a zoom range of 150 - 500mm f / 5 - 6.7 Di III VC VXD for full frame Sony cameras. Traditionally, the lens has a relatively small size of 8.3 in (209.6 mm) x 3.66 in (93 mm) and a weight of 60.8 oz (1.275 g). Tamron used a VC (vibration compensation) mechanism to stabilize the lens. There are three VC modes to choose from depending on what you're shooting - standard, panning, framing. The lens has 25 elements in 16 groups for a minimum focusing distance of 23.6 in (0.6 m) when zoomed out and 70.9 in (1.8 m) when magnified. Zooming in from 150mm to 500mm requires only a 75° rotation of the bezel, less than a quarter of a turn. The lens uses the Tamron VXD autofocus motor, it is resistant to moisture and dust. The lens is equipped with a tripod mount compatible with Arca-Swiss with holes for attaching a strap, and also has a "FLEX ZOOM LOCK" mechanism that allows you to lock the zoom. The lens will be available for purchase in June for $1,399.

The Tamron 11-20mm f / 2.8 Di III-A2 RXD is an ultra-wide lens designed for Sony APS-C cameras. The lens offers a full frame equivalent of 16.5 - 30mm. The lens is small 3.4 in (86.2 mm) long and its diameter is 2.87 in (73 mm). The lens weight is 11.8 oz (335 g) and it consists 12 elements in 10 groups, the shutter consists of 7 blades and the thread for attaching the filters is 67mm. The minimum focus distance is just 5.9 inches (15mm). The magnification ratio is 1: 4 - and 9.4 inches (24 cm) when magnified. The lens is resistant to moisture. A bit disappointing is the lack of VC (vibration control) to stabilize recorded video. Thanks to the use of RXD (Rapid eXtra-silent stepping Drive) motors autofocus noise should not be a problem. The lens is expected to go on sale June 24 at a price of $829.

The new Pocket Polaroid will use the new 2.6 inch wide film. The camera has an easy-to-use double exposure mode, a self-timer and a selfie mirror. In the box with the camera you will find a USB charging cable, a neck strap, a user manual and two Go Colors (16 images) film packages. The camera can be charged via USB and is designed to withstand 15 packages of film on a single charge. The development time for each image is 10-15 minutes.

Press release: Fujifilm Announces New FUJINON XF18mmF1.4 R LM WR Lens A Versatile New Take on a Popular Focal Length Valhalla, N.Y., April 15, 2021 - FUJIFILM North America Corporation is pleased to announce its FUJINON XF18mmF1.4 R LM WR lens (XF18mmF1.4), expected to be launched in May, 2021. With a 35mm equivalent focal length of 27mm, and a maximum aperture of F1.4, it is the 39th lens in Fujifilm’s broad line of interchangeable lenses, made exclusively for the X Series family of mirrorless digital cameras. Its lightweight, highly portable design makes it an ideal lens for everything from landscapes and cityscapes to portraits and weddings. Added flexibility in dimly lit environments is also provided through the lens’ wide F1.4 aperture, which also produces incredibly smooth bokeh. “Keeping to our X Series philosophy of creating lightweight and compact imaging solutions that produce phenomenal image quality, XF18mmF1.4 is a well-balanced and versatile option for any image-maker,” said Victor Ha, senior director of marketing and product management, Electronic Imaging Division at FUJIFILM North America Corporation. “We are really excited to see what stories and images our community of image-makers will create with this lens. It’s certainly ideal for street photography and landscapes, but we’re also looking forward to seeing how it will be used to make wedding and portrait images. There are a lot of creative possibilities with this lens, and I’m confident we’re going to see some great content.” Main features Exceptional optical performance, even at F1.4 XF18mmF1.4 utilizes three aspherical lenses and an extra-low dispersion (ED) lens among its 15 lens elements, spread across 9 groups, to minimize chromatic and comatic aberration. This means the finest details of an image will be reproduced with high levels of sharpness. The focusing group of six lens elements moves in unison to minimize aberration fluctuations and deliver consistent sharpness at any focusing position. Designed for versatility XF18mmF1.4 has a 35mm equivalent focal length of 27mm and can achieve focus on subjects 4.33in (11cm) away from the front lens element. This gives the lens a broad range of applications, from making images of everyday moments, to using it to create sweeping landscapes. Fast, accurate, and near-silent autofocus XF18mmF1.4 uses an internal autofocus (AF) system, driven by a powerful linear motor, to provide fast, accurate, and near-silent AF. From the lens’ minimum object distance (MOD) of 7.87in (20cm) to infinity, the focusing group of lens elements travels a total of just 0.1in (2.5mm). This means focus can be acquired in as quickly as 0.04 seconds*1 . If the lens must travel beyond MOD to acquire focus, focus can still be achieved in as quickly as 0.25 seconds. For precise control when manually focusing, components in the manual focusing ring assembly have been specially engineered to respond with precision, especially when the focusing ring is rotated slightly. Compact, lightweight and weather-resistant XF18mmF1.4 has a 62mm filter thread, measures 2.98in (7.56cm) in length, and weighs just 0.81lbs. (370g). This makes it incredibly lightweight and portable. While the lens barrel is made from metal, it is specially designed to minimize its weight without compromising its overall strength. The lens has weather-resistant seals at eight locations along the lens barrel, making it resistant to dust, moisture, and temperatures as low as 14°F (-10°C) when used with a weather-resistant X-Series digital camera. XF18mmF1.4 is designed with an A (Auto) Position Lock to lock the aperture ring into the A position, preventing accidental movement. Optional accessory: LH-XF18 Lens Hood Fujifilm has also developed a rectangular, aluminum lens hood for XF18mmF1.4 that helps to prevent lens flare and ghosting which can occur when beams of light strike the front element of the lens. The LH-XF18 Lens Hood will be made available in late May, 2021. Pricing and Availability FUJINON XF18mmF1.4 R LM WR Lens is expected to be available in late May, 2021 at a manufacturer’s suggested retail price of $999 USD and $1,275 CDN. The LX-HF18 lens hood accessory will also be available at this time for a manufacturer’s suggested retail price of $69 USD ($80 CDN).

Press Release: DEVELOPING NEWS: CANON ANNOUNCES THAT THE POWERFUL PROFESSIONAL FULL-FRAME EOS R3 MIRRORLESS CAMERA IS ON ITS WAY The Company Is Also Welcoming Three New RF Lenses: The Canon RF100mm F2.8 L Macro IS USM, RF400mm F2.8 L IS USM and RF600mm F4L IS USM MELVILLE, NY, April 14, 2021 - Canon U.S.A. Inc., a leader in digital imaging solutions, today announced that its parent company, Canon Inc., is developing a new, high-performance professional camera — the Canon EOS R3*. When it arrives, the EOS R3 will be an outstanding complement to the three new RF lenses the company also introduced today — The Canon RF 100mm F2.8 L Macro IS USM, RF400mm F2.8 L IS USM and RF600mm F4 L IS USM. “The development of the Canon EOS R3 and the launch of the new RF lenses are the latest testament to the company’s commitment to professional still and video image and content creators,” said Tatsuro “Tony” Kano, executive vice president and general manager of Canon U.S.A.’s Imaging Technologies & Communications Group. “When the camera becomes available, it will pair well with each of the new RF lenses announced today. Canon is excited to share this news today, and we look forward to seeing the images captured with the new RF lenses and upcoming EOS R3.” Under Development - The Canon EOS R3 The Canon EOS R3 will join the current lineup of EOS R full-frame mirrorless series cameras. This camera will usher in a new category to the EOS R system, positioned squarely between the EOS R5 and EOS-1D X Mark III cameras. The camera will put great emphasis on superb AF performance and speed, with fast-moving subjects. It is being designed to meet the reliability and durability demands of professionals, even when working in challenging conditions. At the heart of the EOS R3 camera’s performance will be an EOS camera first, a Canon-developed, full-frame stacked CMOS sensor with a back-illuminated design, providing substantially faster read-out speeds during still-imaging recording. This completely new sensor is designed to produce less “rolling shutter” distortion during Electronic Shutter operation and offer continuous Electronic Shutter still-image shooting at speeds up to 30 fps — with full Dual Pixel CMOS AF and auto exposure1. The AF system will leverage technology and performance from the well-received EOS R5 and EOS R6 cameras, using Deep Learning technology to further enhance eye and body detection for even better performance during portrait and action-type shooting. In addition, the EOS R3’s subject detection AF will offer new recognizable subjects for its AF system, bolstering its focusing capabilities during challenging shooting conditions. The Electronic Viewfinder of the EOS R3 will offer photographers the ability to select the initial area for AF tracking by simply looking directly at the viewfinder location where they want to begin AF. With Eye Control AF2 and Servo AF activated, the camera will focus on and track moving subjects at that location in the frame. When Face Detect + Tracking is active, the camera will continue to follow moving subjects around the entire active AF area. The camera body will be entirely new and accentuates the camera’s high-performance design. It’s a one-piece design, integrating the body with a vertical grip section. The weather and dust-resistance will be equivalent to that of EOS-1D class cameras — an essential consideration for nature, wildlife, sports and photojournalism content creators working in extreme conditions. In addition, news photojournalists will be excited to add the Mobile File Transmitter application for iOS and Android devices that will be available. Full details of all the EOS R3’s features and specifications will be provided at the time of its formal announcement*.

Sony has introduced slightly changed versions of the well-known a7R III and a7R IV full-frame mirrorless cameras. The new versions are called ILCE-7RM3a and ILCE-7RM4a - as you can see, they are distinguished from previous cameras by the letter 'a' added in the name. The only spec enhancements known are LCD displays with a higher resolution of 2,359,296 pixels, a faster USB port and slight changes in battery performance. As you can see in the photos below, the Sony logo has disappeared from under the LCD screen.
