Leica introduces APO-Summicron-SL 28mm F2 L-mount lens

Published Feb 18, 2021
|
Leica has introduced the APO-Summicron-SL 28mm F2 ASPH lens for full-frame L-mount bodies. It features 13 elements, 6 of which are aspherical; several of the elements are of the anomalous partial dispersion type to reduce chromatic aberration.
The lens can focus as close as 24cm (9.5″) and the maximum magnification is 0.2X. The focus group is driven by a stepping motor that Leica calls ‘Dual Syncro Drive’. The 28mm F2 has a newly designed manual focus ring that uses magnetic fields to improve responsiveness and precision.
The 28mm F2 is weather-sealed and weighs in at 700g (1.5lbs) without its hood. It accepts 67mm filters.
The APO-Summicron-SL 28mm F2 ASPH is now available for $5195.
Press release:
Leica Launches the APO-Summicron-SL 28 f/2 ASPH.:
Exemplifying A Commitment to Developing High-Performing Innovative Technologies in the World of Camera Optics
February 18, 2021. With the APO-Summicron-SL 28 f/2 ASPH., Leica Camera presents yet another high-performance wide-angle lens for the Leica SL-System. The APO-Summicron-SL 28 f/2 ASPH. is the latest addition to the ever-expanding APO-Summicron-SL series that includes a lens range renowned for its top-level optical performance and extremely fast and reliable autofocus.
Following the existing focal lengths of 35, 50, 75 and 90 mm, the APO-Summicron-SL 28 f/2 ASPH. is the first true wide-angle prime lens in this series, making the APO-Summicron-SL 28 f/2 ASPH. especially suitable for reportage, interior and architectural photography. Its maximum aperture can be used without any loss of image quality and offers additional creative possibilities through the exquisite balance of sharp subjects and lovely soft background blur. Thanks to the L-Mount standard, the APO-Summicron-SL 28 f/2 ASPH. is equally compatible with cameras made by other partners of the L-Mount Alliance that have been equipped with the Leica-developed lens mount.
As is universally appreciated with all Leica lenses, the fastest aperture delivers maximum performance. As a result, reducing the aperture is only necessary for compositional and creative purposes. Leica lenses always deliver an exceptional quality of natural skin tones, soft transitions into creamy bokeh, contrast-rich details and edge-to-edge sharpness across a distortion-free image. Yet the APO-Summicron-SL 28 f/2 ASPH. is further distinguished by its apochromatic correction, which is a notable feature in a lens of this focal length, and its six aspherical lens surfaces. To ensure the optimal correction of chromatic aberrations, the majority of the grouped lens elements feature anomalous partial dispersion and are made of high-quality specialized glass. The end result is a wide-angle lens that delivers impeccable images complete with the “Leica Look” to help realize a creative vision in any avenue of photography.
The autofocus drive of all APO-Summicron-SL lenses utilizes extremely robust and high-performance stepping motors with DSD® (Dual Syncro Drive™). This enables the AF to travel the entire focusing range in around 250 milliseconds. Leica Camera also takes an innovative approach to manual focusing technology, including an entirely new manual focus ring construction in the form of an embedded ring magnet with alternating north-south polarization. When the ring is turned, the magnetic field changes its polarity. A sensor monitors the status of the magnetic field and sends the data to the main processor. The drive then shifts the lens to the corresponding focusing position based on the angle of rotation and the rotational speed, delivering even faster and more precise manual focusing to match the lens’s quick and accurate autofocus.
Both the construction and design of the cutting-edge APO-Summicron-SL series represent the next step forward in the development of lenses for the Leica SL-System. New, extremely precise manufacturing methods and measuring technologies have been developed specifically for the production of these lenses, resulting in more compact dimensions as well as truly outstanding imaging performance. In the construction of the APO-Summicron-SL lenses, particular attention has been paid to the prevention of stray light and reflections by applying a high-quality coating to the lens surfaces. Thanks to their effective sealing against dust, moisture, and water spray, as well as the Aquadura coating of the exposed lens surfaces, these extremely durable lenses can be used in nearly any weather condition without any cause for concern. The ever-expanding portfolio of Leica SL lenses are built to withstand the elements and the test of time, matching its futureproof counterparts in the SL2 and SL2-S with their rugged construction and continuing firmware development ensuring a long service life.
The APO-Summicron-SL 28 f/2 ASPH. is available now at Leica Stores, Boutiques and Dealers for $5,195.00.

Inspiring US outdoor photography TV show gains national scope in third season
US Public Broadcasting Service’s (PBS) outdoor photography show is back for a third season with a broader, national scope and nationwide availability. View Finders has grown from a quiet regional favorite into a nationally distributed, Emmy-nominated PBS series. The show, which is only viewable in the US, is hosted by professional photographers Chris Greer and Paul Daniel. It follows the duo as they explore breathtaking landscapes across the United States, seeking stellar shots while sharing tips on lighting, composition and storytelling through photography.
What began as a YouTube project focused on Georgia’s natural beauty has evolved into a cross-country adventure. Season three premiered on March 17th and takes viewers to Grand Teton National Park, the Wind River Range and the White Mountain National Forest, among other destinations. View Finders’ mission remains unchanged: celebrate the outdoors, educate the public about these places’ ecological and cultural importance and inspire others to connect with nature through photography.
“The show has grown tremendously,” Greer, who is also a Georgia College & State University professor, told Flagpole. “It’s kind of transformed from a Georgia-based television show to a national television show, and this season reflects that national footprint.”
The road to national syndication began after two successful seasons on Georgia Public Broadcasting. In 2023, Greer pitched the series to 300 PBS (Public Broadcasting Service) stations nationwide and received a warm reception. In Greer’s opinion, what sets View Finders apart is its unique blend of adventure, photography, and conservation, an angle not often explored on traditional travel shows.
The show also addresses the growing urgency around public land preservation. With interviews from park rangers, ecologists and historians, View Finders integrates expert commentary into each episode. Beyond seeing beautiful places, viewers learn why they matter and must be protected, “so they don’t turn into developments and condos.”
The View Finders crew captured footage using lenses like SIGMA’s SPORTS 60-600mm F4.5-6.3 DG DN OS.

Another signature element of the series is its music. The soundtrack features a blend of independent southern artists and nationally known names like Hozier and Bon Iver. This season highlights music from Athens, Georgia-based acts including Grassland String Band, Family and Friends, and Hotel Friction. Greer believes the combination of powerful music and visuals creates an immersive experience and resonates emotionally with the audience.
All third-season footage from Greer, Daniel, and camera operator Nathan Burnett was filmed using Sigma lenses, as the company is the official lens sponsor. You can watch episodes from all seasons, including the current season, on PBS’ official site. The final three episodes for this season will air soon. Greer told us that distribution for the UK, additional European and worldwide markets isn’t finalized at this time, though the show could potentially find international audiences at some point.

DHL suspends international shipments over $800 to the US

DHL Express, the world’s second-largest delivery company, has temporarily suspended some of its international shipments to the United States, citing a surge in customs processing requirements tied to new US import rules. The change, which went into effect today, impacts business-to-consumer (B2C) shipments with a declared value over $800, as Fox Business reports. For example, consumers ordering camera gear from Sony or drones from DJI could face significant delays.
The suspension follows a policy revision by US Customs and Border Protection, which quietly lowered the threshold for formal customs entry from $2500 to $800 on April 5th. Under the new rules, any shipment entering the US valued above $800 is subject to a more complex customs process, including additional paperwork, duties and inspections. For logistics providers like DHL, this change triggered an immediate spike in formal entries, creating bottlenecks across international networks.
In a statement to customers, DHL said it saw “multi-day transit delays” for packages over the $800 threshold and confirmed that it would no longer collect or ship those parcels if destined for private individuals in the US. The company stressed in its last announcement that “this is a temporary measure, and we will share updates as the situation evolves.” DHL is reportedly scaling up operations to handle the uptick in customs volume, but it hasn’t offered a precise date for when service will normalize.

The suspension is explicitly limited to international B2C shipments, packages sent from businesses abroad to individual customers in the US, with a declared value over $800. Lower-value packages, including all shipments under this amount, are not affected and will continue as usual.
Business-to-business (B2B) shipments, packages sent between international companies and US-based businesses, are also exempt from the suspension. However, due to increased workload at customs, they may face processing delays. This can potentially impact new product shipments to retailers, including B&H and big-box stores such as Best Buy.
The policy shift has sent shockwaves through international shipping and e-commerce channels. The effects of US Customs change are being felt beyond DHL. Earlier this month, Hongkong Post suspended its sea mail service in response to what it deems unfair trade tactics by the US. DHL will continue processing shipments from Hong Kong but has warned that customers should expect slower processing times and prepare for more changes, in light of more regulatory adjustments expected on May 2nd.

US officials have not publicly commented on the motive behind the customs threshold adjustment. The move, however, is deemed as a broader effort to tighten control over under-declared shipments, counterfeit products, and illegal drugs such as fentanyl, all of which amount to lost tax revenue. It could also increase pressure to localize inventory.
While DHL works to resolve internal backlogs and scale its infrastructure, affected businesses and consumers will be impacted. We’ve become increasingly reliant on fast global delivery; even a temporary disruption like this has wide-reaching consequences. If you’re ordering any new gear from your favorite electronics brand’s official website, you should be prepared to track updates and plan for continuous delays.

The Vivo X200 Ultra aims to be more camera than phone

Image: Vivo |
Smartphone maker Vivo has released its latest device, the X200 Ultra. The Vivo X100 Ultra was widely seen as one of the best camera phones from last year, though it was only available in China. Unfortunately, its new device will likely have the same limitation, though it is still worth looking at, as Vivo is marketing it as “a camera that happens to be a phone.” Vivo has been teasing details for some time, but today it has officially hit shelves in China.
Resolution | Sensor | Aperture | Equiv. focal length | |
---|---|---|---|---|
Main camera | 50MP | Type 1/1.28 (9.9 x 7.5mm) | F1.69 | 35mm |
Ultrawide | 50MP | Type 1/1.28 (9.9 x 7.5mm) | F2.0 | 14mm |
Telephoto | 200MP | Type 1/1.4 (9.1 x 6.7mm) | F2.7 | 85mm |
Selfie | 50MP | 1/2.76 (5.2 x 3.9mm) | F2.5 | 24mm |
The X200 features the typical three rear cameras: an ultrawide, a main camera, and a telephoto. Interestingly, the main camera offers a 35mm equiv. focal length, whereas most smartphones use a 24mm equiv. focal length. The 35mm angle of view is more versatile (and natural-looking) than 24mm, which is why it is such a standard focal length for photographers. Though a subtle change, it is nice to see a company rethinking that main camera.
The phone also features a 3.7x periscope telephoto camera that offers the highest resolution of the three, thanks to the Samsung HP9 200MP sensor. Samsung released the sensor last summer and claimed it was the first 200MP sensor for telephoto cameras.

Where things get unique, though, is with the optional Photographer Kit. Lately, we’ve seen many handgrip add-ons for smartphones to make them more camera-like, either from the phone manufacturer directly or from accessory makers. Vivo has gone the latter route. The Photographer Kit includes the 16GB/1TB phone, a camera grip, a shoulder strap, a case and a 2.35x telephoto converter lens. While we’ve seen a few detachable camera lenses for smartphones lately from the likes of RealMe and Xiaomi, those were concepts and are not currently available for purchase.
Like all of the integrated lenses on the X200 Ultra, the add-on lens was co-engineered with Zeiss. The cute telephoto lens attaches via a custom adapter, sitting over the 200MP telephoto camera. The lens features 13 lens elements with an F2.3 aperture. It offers a 200mm equiv. focal length with 8.7x optical zoom and up to 70x hybrid zoom (a combination of optical and digital zoom), resulting in up to a 1600mm equiv. Vivo claims that images from the optional lens are “highly usable” at 35x.

The grip looks similar to Xiaomi’s Photography Kit. It features a vintage look and convenient camera controls, including a shutter button, a customizable control dial, zoom controls and a video recording button. It also offers a 2,300mAh battery to extend the phone’s battery life, something that’s especially useful when taking lots of photos or videos with your phone.

The X200 Ultra also features two custom imaging chips: one for pre-processing tasks and one for post-processing. It’s capable of 4K 60p 10-bit Log video from all three rear cameras, as well as 4K 120p video on all three rear cameras. Plus, even if you don’t opt for the Photographer Kit, there’s a dedicated shutter button on the phone itself that allows you to slide to zoom or adjust exposure, like Apple’s Camera Control feature.
Outside of camera specs, the phone runs on the Origin OS 5 Android skin, which is exclusive to China. It features a 6.8-inch AMOLED display with a resolution of 1260 x 2800 and peak brightness of 4500 nits. The phone’s internals include the Snapdragon 8 Elite chipset and a 6000mAh battery, all of which are wrapped in an IP69 rating.
The X200 Ultra is available in China as of today in silver, red or black. According to Android Authority, the 12GB/256GB model is priced at 6499 yuan (roughly $890) while the top-end model (16GB/1TB) is 7999 yuan ($1096). The Photographer Kit, which comes with the top-end model, will cost 9699 yuan ($1329), though you can also buy it without the phone for a promotional price of 1699 yuan ($233) or full-priced at 2598 yuan ($356).
