Hubble scientists revisit an incredible image of Veil Nebula, showing off new details
In 2015, the Hubble Space Telescope captured an image of the Veil Nebula. NASA has revisited this image and applied new processing techniques, bringing out even finer details of the nebula.
NASA, ESA/Hubble and Z. Levay have been able to bring out additional details in the ionized gas that makes up the threads and filaments of the nebula. Observations taken by Hubble’s Wide Field Camera 3 instrument using five different filters were combined with new post-processing methods to create the new image. You can see enhanced details of emissions from doubly ionized oxygen (seen in the image as blue colors), ionized hydrogen, ionized sulfur (green) and ionized nitrogen (seen as reds in the photo).

| This close-up image of the Veil Nebula was first captured in 2015. It has been reprocessed to show a better view of the nebula and its filaments of ionized gas. The ionized gas is all that remains of a supernova that about 20 times the mass of the Sun. ‘The fast-moving blast wave from the ancient explosion is plowing into a wall of cool, denser interstellar gas, emitting light. The nebula lies along the edge of a large bubble of low-density gas that was blown into space by the dying star prior to its self-detonation.’ Image credit: ESA/Hubble & NASA, Z. Levay |
The Veil Nebula is about 2,100 light-years from Earth in the constellation of Cygnus, otherwise known as the ‘Swan.’ As NASA writes, in astronomical terms, Cygnus is a relatively close neighbor.

Astronomer William Herschel first identified the Veil Nebula way back in 1784. In 1904, Herschel’s work was followed by Williamina Fleming’s discovery of a fainter portion of the nebula, known as Pickering’s Triangle, named after the director of the Harvard College Observatory where Fleming worked. If you’d like to view the Veil Nebula for yourself, the best observation time is early autumn in the northern hemisphere and early spring in the southern hemisphere. The nebula is not visible to the naked eye, but it can be seen through a telescope or binoculars under dark sky conditions. If you have a nebula filter, it will help brighten the Veil’s appearance and allow you to see additional detail.
The Veil Nebula is a visible portion of the Cygnus Loop, which is the remnant of a supernova formed about 10,000 years ago. The Veil Nebula formed through the death of a massive star, which possessed roughly 20 times the mass of the Sun. Like other stars of that size, it had a relatively short lifespan and died with a massive release of energy. The energy and debris from this supernova form the Veil Nebula’s tendrils of ionized gas.

The original image and the reprocessed version show only a small section of the Veil Nebula, which is continually expanding. The entire nebula is 110 light-years across, covering about six full moons’ worth of the night sky as viewed from Earth. The section we see in the shot from Hubble, which is a six-image composite, is about two light-years across.
Back in 2015, when showing off its new image of the Veil Nebula, NASA also shared a couple of neat videos. The videos haven’t been redone with the latest processed image, but they’re nonetheless worth checking out again.

Landscape Photographer of the Year: 1st place
 |
Photographer: Andrew Mielzynski, Canada
Subject and location: Winter Cottonwoods, Toronto, Ontario, Canada
Description: During the pandemic, I went out for a walk at a local park during a fierce winter storm. I ran across this scene. It seemed very chaotic, with many layers of trees. I loved how the snow, driven by high winds, was embedded into the bark of the trunks. The snow on the bark created a textural contrast that adds detail and interest to the trees. I took a few frames, trying to simplify the scene in front of me and settled on this one, loving the tones, the depth, the order and the minimalism. Even in a chaotic scene, there seems to be a sense of balance that feels orderly and pleasing.

Photographer: Andrew Mielzynski, Canada
Subject and location: Found in a roadside ditch near Heathcote, Ontario, Canada
Description: After a melt, we had a flash freeze with extremely cold temperatures and a clear blue sky. I was driving by a ditch on the side of a road that had been filled with water and had to stop and look (as we photographers do, can’t pass a ditch without investigating). This is what I found. Great textures and patterns, tones and flow, with lovely graphic lines creating a dynamic, abstract designs. I love this type of work – it’s so much fun, yet challenging to find just the right composition.

Description: The Landscape Photograph of the Year Award went to Ryohei Irie of Japan. He likes the mysterious atmosphere created by the standing dead trees and firefly light. “I have been visiting this Subject and location for several years during the firefly season, and it is an interesting place because the intensity and length of the firefly light and the Subject and location where the fireflies fly vary greatly, depending on the year and time of day, resulting in completely different works, even when photographed in the same way.”

It wasn’t long ago that many of our reviews of APS-C cameras had to come with a warning: no matter how good the body was, you were almost certainly going to be limited by lens selection. This was especially true with Nikon and Canon’s mirrorless cameras. Sony has followed its longstanding tradition of letting third parties build out a healthy selection of lenses, and the selection for Fujifilm’s APS-C-only X-mount is second to none, but Nikon’s Z mount and Canon’s RF mount appeared to be almost completely locked down. As a result, you could count the number of APS-C lens options available on your fingers.
But things are changing. Over the past year, we’ve seen several APS-C lenses announced and released for Canon and Nikon cameras, filling notable gaps in the first-party lens lineups. But while the situation is improving, it’s clear that the two companies are still in control.
This week, Sigma released four APS-C primes for Canon’s RF mount, making good on its promise to release six licensed lenses for the system – earlier this year, it released the 10-18mm F2.8 and 18-50mm F2.8. Meanwhile, Nikon has allowed Sigma to release select primes for Z-mount – a trio of F1.4 primes at 16, 30, and 56mm. It’s worth noting the company’s 23mm F1.4 is the only one of its APS-C primes that it hasn’t brought to Z-mount; it likely isn’t a coincidence that Nikon’s only first-party APS-C prime lens is a 24mm F1.7.
 |
|
Sigma’s APS-C prime lens lineup is quite good, and now most of them are available for almost any mirrorless APS-C camera.
Image: Sigma |
However, Nikon hasn’t stopped companies like Viltrox and Sirui from releasing a slew of Z-mount APS-C prime lenses, complete with autofocus. If you pick up a Nikon Zfc or Z50II, you can get anywhere from a 13mm F1.4 (20mm equiv.) to a 75mm F1.2 (113mm equiv.) to go with it, as well as most of the classic focal lengths in between.
Your choices are no longer limited to a few first-party options, manual-focus only lenses, or glass meant for full-frame bodies
This is an important change for APS-C shooters. Even going back to the DSLR days, it’s felt like many manufacturers have viewed the format as a stepping stone to full-frame rather than something enthusiasts and pros might consciously choose. Neither Canon nor Nikon have been particularly prolific when releasing new APS-C glass. But with the gates being slightly opened, you’re no longer limited to a few first-party options, manual-focus-only lenses from third parties, or heavier, more expensive full-frame lenses. Now, there’s at least some selection of third-party lenses with autofocus to choose from, alongside Canon and Nikon’s offerings.
This isn’t to say that you can now buy any APS-C camera you want and be assured that all the lenses you want will be available – you are still at the mercy of what Canon and Nikon wish to allow. While plenty of primes are available for Z-mount APS-C cameras, no fast zoom lenses are available; Nikon’s all start at F3.5 and end at F5.6 or F6.3.
In fact, there are currently no third-party APS-C zooms available for Nikon Z-mount at all, despite the fact that two have made the jump from E and X-mount to RF – it also goes without saying that there are many others more available on Fujifilm and Sony’s systems. That’s a bummer for anyone looking to step up from the kit lens or wanting to shoot sports or birds in anything but ideal lighting without having to shell out for and lug around a full-frame 70-200mm.

Tamron has promised to bring its 11-20mm F2.8 APS-C lens to Canon RF mount this year as well – no word on Z-mount, despite Tamron bringing some of its full-frame lenses to Nikon.
Image: Tamron |
RF mount at least has the two constant F2.8 zooms thanks to Sigma, with one more on the way from Tamron, though those are all at the wide end. However, there are far fewer autofocus primes available for Canon, as manufacturers like Sirui and Viltrox aren’t producing them. That’s not surprising; a representative for the latter once said that Canon had told it to stop producing products for RF mount. The 85mm F1.4 lens that Samyang announced for the system in 2020 also disappeared from the market not long after.
In a perfect world, these problems wouldn’t exist. Canon and Nikon would make the lenses that their APS-C cameras needed to stand on their own feet as a real alternative to full-frame options, and there would be robust competition from third parties, which would be allowed to make whatever lenses they want.
None of that seems particularly likely. However, at least those who choose to shoot with a smaller sensor in a Canon or Nikon body have gotten a wider choice of lenses, even if they’re still bound by the companies’ rules.
At the end of the day, that’s better for everyone interested in APS-C, because it means that cameras like the EOS R7 and Z50II are competitive with the Sony a6700 and Fujifilm X-T5 in a way that they wouldn’t have been with an extremely limited lens selection. With any luck, this trend will continue, and the APS-C landscape will become more competitive – even if Canon and Nikon aren’t giving it their full attention.

Sony has announced the FE 28-70mm F2 GM, a zoom lens that trades 4mm at the wide end for an aperture that’s a stop brighter than the one found on a classic 24-70mm F2.8. It’s the company’s first constant F2 zoom lens for its E-mount cameras.
The lens’s optical formula consists of 20 elements in 14 groups, with three aspherical lenses, three super ED elements, and one ED element. It uses an 11-blade aperture. The front element has an oil and water-resistant flourine coating, and the lens is moisture and dust resistant.
It’s far from a compact lens, though it’s not as monstrously large as you might expect – it weighs in at 918g (32 oz) and is around 140mm (5.5″) long. It has an 86mm filter thread.
Sony makes it obvious what lens it’s competing with; highlighting that it’s 36% lighter and 11% smaller in diameter than Canon’s RF 28-70mm F2 L lens while claiming better corner-to-corner sharpness. The company also says the lens’s four linear motors can focus even when shooting at 120fps, and emphasized that they’re quieter than the older ring-type ultrasonic style motor in the Canon F2. In fairness, that lens was one of the original RF-mount releases, announced in 2018.
“Sony makes it obvious which lens it’s competing with”
The quieter operation should help when shooting video. Other pluses for video: it has an internal focusing mechanism which should make it easier to use the lens on a gimbal, the ability to switch the aperture ring into clickless mode and supports the focus breathing compensation mode included on some Sony bodies. You can also set the manual focus ring to have a linear response, which should make focus pulls easier.
The lens has a variety of switches and buttons. There are two customizable focus hold buttons, an Iris lock switch, the aperture click switch and a zoom smoothness switch that lets you adjust between “smooth” and “tight” torque settings.
It’s not the fastest zoom lens available for E-mount: at the time of writing, that prize goes to Sigma’s 28-45mm F1.8, though that model has substantially less reach on the tele end and only a 1/3EV increase in light-gathering ability.
The FE 28-70mm F2 GM will be available in mid-December and has an MSRP of $2,899.
Sony Electronics Announces Its First Constant F2 Aperture Zoom Lens: The Full-Frame 28-70mm F2 G Master™
The Unique Combination of a Versatile Focal Range, Large F2 Aperture, and Compact Form Factor
SAN DIEGO, Nov. 19, 2024 – Sony Electronics Inc. introduces the 28-70mm F2 G Master, the first1 Sony zoom lens with a constant F2 aperture and 77th lens in the Sony E-Mount lineup. This full-frame lens offers a versatile focal range from 28mm to 70mm while delivering prime-like2 bokeh with its constant F2 aperture. Despite its wide aperture and zoom range, the 28-70mm F2 G Master remains compact, lightweight, and well-balanced, making it ideal for both photography and video applications. This combination of zoom range, large aperture, and compact design makes this an innovative and versatile lens for portrait, sports, wedding, event, and video professionals.
“Our goal with the 28-70mm F2 G Master was to create a high-performing zoom lens that could be a strong single lens alternative to multiple primes,” said Yang Cheng, Vice President of Imaging Solutions, Sony Electronics Inc. “We prioritized a lightweight design during the engineering process as we knew that was a critical factor for real-life, practical use. And in a manner that only Sony can do, we were able to deliver a small, standard F2 zoom lens that does not sacrifice image quality. We’re proud to add this to our G Master series and believe it is one of the most innovative lenses ever offered to professionals.”
Sharp Imagery and Beautiful Bokeh
The 28-70mm F2 G Master produces extremely sharp corner-to-corner results throughout the entire zoom range, even while shooting wide open at F2. The high-resolution output is made possible by the three XA (extreme aspherical) elements and three aspherical elements built within the lens that minimize aberrations. The lens also features a floating focusing system that helps maintain internal stability. This focusing mechanism enables an impressive minimum focusing distance of up to 14.8 inches (0.38m) throughout the entire zoom range.
Staying true to the G Master lens lineage, the lens’ aperture up to F2 produces extraordinary bokeh, ideal for creating images that showcase a shallow depth of field. The 28-70mm F2 amplifies the G Master bokeh standards through a newly designed 11-blade circular aperture unit. Chromatic aberrations, which cause color fringing within photos, are effectively minimized with three Super ED (extra-low dispersion) elements and one ED element built within the lens. Additionally, Sony’s Nano AR Coating II reduces flare and internal reflections, ensuring clear images, even when strong light sources are present in the frame.
Compact, Lightweight Design Without Compromising Quality
The 28-70mm F2 G Master is one of the most advanced mirrorless camera lenses manufactured with a total 20 different lens elements arranged within 14 internal groups. Despite the advanced optical design, the lens remains compact at 3.6 x 5.5 inches (92.9 x 139.8mm) and lightweight at approximately 32.3 ounces (918g). The combination of imaging performance and a compact form factor offers an innovative solution that meets the demands of industry professionals.
Precise Autofocus Tracking with Instant Response
Reliable and responsive autofocus is delivered through the lens’ four XD (extreme dynamic) linear motors powered by advanced control algorithms. This smooth performance system provides accurate and quick focus tracking, often essential in many professional use cases like weddings and sports. This lens is fully compatible with Sony’s Alpha 9 III‘s high-speed continuous shooting capabilities of up to 120 frames per second3 with AF/AE (autofocus/autoexposure) tracking, even while zooming.
Designed for High-Performance Video Shooting
Along with its F2 aperture, the zoom range of the 28-70mm G Master provides a versatile video option that can cover standard field-of-view shots and tighter compositions up to 70mm. This lens minimizes focus breathing through its build and compatibility with the Breathing Compensation feature on various Alpha bodies4. Its high autofocus performance ensures reliable focus even when recording in high frame rates up to 4K 120p / FHD 240p5. Additionally, the XD linear motors and newly developed aperture unit operates silently, preventing any lens noise from being captured during filming.
The lens is ideal for gimbal use with a minimal zoom extension of approximately .68 inches. The compact form factor and short external zoom helps maintain gimbal balance, even at varying focal lengths.
Operability and Reliability for Versatile Control
Key control features include Linear Response MF for intuitive manual focusing, adjustable zoom ring torque, and an aperture ring with a click ON/OFF switch. The lens also offers two customizable focus hold buttons, an iris lock switch, and an AF/MF switch. The 28-70mm F2 G Master has an 86mm filter diameter and a convenient window on the lens hood for variable filter adjustments.
For durability, all buttons and switches are sealed with silicone gaskets, and critical areas are designed to resist dust and moisture6. This ensures reliability, even while using in challenging outdoor environments. Additionally, a fluorine coating on the front element repels contaminants for easy cleaning.
Pricing and Availability
The 28-70mm F2 G Master will be available in December 2024 for approximately $2,899.99 USD and $3,999.99 CAD. It will be sold at a variety of Sony’s authorized dealers throughout North America.
