Sigma has announced pricing and availability for the AF Cine Line 28-45mm T2 FF, its first autofocus cinema lens for full-frame cameras, which it teased earlier this year. The lens is based on the company's mirrorless 28-45mm F1.8 DG DN Art lens, but Sigma says it has "completely redesigned electrical and mechanical parts to provide the focus and aperture drive features required for use with cinema cameras."

The company says the lens has a clickless aperture ring and standard gears for use with follow-focus systems. Its autofocus system is driven by a linear motor, the same one found in the mirrorless version. Sigma says the E mount version will be compatible with Sony's Direct Manual Focus and AF Assist features, and with L mount cameras' AF+MF system.

Despite the much chunkier housing and gears, the cinema lens only weighs 60g more than the Art model.

The Sigma AF Cine Line 28-45mm T2 FF will be available in early November and will retail for $3399, a roughly $1900 premium over the mirrorless version.

Ronkonkoma, NY, September 9, 2025 – Sigma Corporation of America, the US subsidiary of Sigma Corporation (CEO: Kazuto Yamaki. Headquarters: Asao-ku, Kawasaki-shi, Kanagawa, Japan), is pleased to introduce the Sigma AF Cine Line 28-45mm T2 FF, the first lens in the AF Cine Line and first Sigma Cine lens to feature autofocus capabilities.

Based on the optical formula of the 28-45mm F1.8 DG DN | Art lens, the 28-45mm T2 FF is designed to support full-frame camera sensors with completely redesigned electrical and mechanical parts to provide the focus and aperture drive features required for use with cinema cameras. In addition, the appearance and build quality are representative of a premium cinema lens, with exceptional dust- and splash-resistant performance for use in varied environments.

Similar to the 28-45mm F1.8 DG DN | Art, the autofocus of the 28-45mm T2 FF is driven by a High-response Linear Actuator (HLA) motor. For manual focus operation, this lens features a focus ring with a distance scale and fixed rotation range. It is compatible with DMF (Direct Manual Focus) and AF Assist on Sony E-mount, as well as the AF+MF function on L-Mount.

Weighing in at 960g*, the 28-45mm T2 FF is only 60g heavier than the 28-45mm F1.8 DG DN | Art, and both lenses are the same length. The 28-45mm T2 FF is also compatible with 82mm front filters, as well as commercially available matte boxes with the addition of the optional clamp-on ring (sold separately).

The Sigma AF Cine 28-45mm T2 FF lens will be available in early November at authorized Sigma Cine Lens dealers in the US for Sony E-mount and L-Mount for a retail price of $3,399 USD.

Sleep is often treated as downtime, a passive break between the real business of being awake. But a new study has revealed that sleep is active, essential biology, showing how the brain uses the night to flood the body with growth hormone to repair muscles, strengthen bones and balance metabolism. Researchers have uncovered the neural circuitry that explains why growth hormone surges during shut-eye, and why cutting corners on sleep undermines our physical health.

The LK Samyang / Schneider Kreuznach AF 24-60mm F2.8 FE

Photo: LK Samyang / nullnullphotos

LK Samyang has announced an autofocus 24-60mm F2.8 full-frame zoom for Sony's E-mount. It's the second lens co-developed with German lensmaker Schneider Kreuznach.

The AF 24-60mm F2.8 joins the 14-24mm F2.8, announced earlier this year. A mockup of the 24-60mm was shown at the CP+ trade show in Japan, in February.

The company hasn't provided full specifications of the lens, but the product images show it to be relatively compact, presumably helped by its shorter-than-usual reach, at its long end. At 102mm long and 500g, it sits directly between Sony's larger, heavier 24-70mm F2.8 GM II and its smaller, lighter 24-50mm F2.8 lenses.

The lens will be formally unveiled at the International Broadcasting Convention in Amsterdam, The Netherlands on September 12th. We'll add more details as they become available.

If you've been following closely at this point, you've already seen plenty of sample images from the Hasselblad X2D II, and probably have a pretty good idea of how well it performs. Of course, we've also put it in front of our studio scene to make it easier to directly compare its image quality to that of other cameras.

As a note: the out-of-camera JPEGs were shot using the camera's Ultra HDR JPEG mode, which adds a gain map on top of a standard JPEG. The comparison tool doesn't support dipslaying them in a way that highlights the bright areas of the image, but you can view them by downloading the original file, and opening it on a device with an HDR display.

Our test scene is designed to simulate a variety of textures, colors, and detail types you'll encounter in the real world. It also has two illumination modes, full even light and low directional light, to see the effect of different lighting conditions.

Unsurprisingly, the X2D II's Raws provide superb amounts of detail at low ISOs, besting the single-shot performance of the a7R V's 61MP sensor and matching the GFX 100S II. At its base ISO of 50, it provides the cleanest image of the bunch; the GFX 100S II has slightly more noise, but still outperforms the a7R V thanks to its larger sensor.

Its JPEGs, however, don't seem to quite do that level of detail capture justice, with the finest parts of the image looking a little softer than they do with the GFX 100S II. The details are generally still present in the JPEG, but they don't stand out as much, at least when viewed 1:1 (though that's likely to be a very unusual use-case for images taken on this camera).

The X2D II's Raws continue to look good even at higher ISOs, though its chroma noise is more noticeable than Fujifilm's. And while the JPEG engine doesn't reduce noise as aggressively, that means it does a better job at preserving details.

We had no issues capturing vibrant colors with the X2D II.

Hasselblad XCD 35-100mm E | 60mm | F3.5 | 1/500 sec | ISO 100

Back at lower ISOs, the Hasselblad's colors are generally less saturated than Fujifilm's or Sony's, though in our use outside the studio, we found that it still produced pleasing skin tones for portrait work. We also didn't have any issues with getting images that popped with vibrant colors, especially with HDR switched on.

As we've come to expect from this sensor, the X2D II has excellent dynamic range at its base ISO, with very little read noise. This means you won't face much penalty for taking an image at ISO 50 to get the maximum DR, then boosting it in post, compared to taking an image at a higher ISO to achieve your desired lightness.

Its files also hold up well when you're boosting shadows, which is helpful if you're shooting at lower ISOs to protect your highlights with plans to brighten the image in post.

Many photographers rarely consider memory card care. We tend to use and abuse our cards, with little thought about how to keep them working at their best. And while memory cards are quite robust and durable these days, there are some best practices to keep in mind to prevent corrupt files or data loss.

Most of us have been there: You're out taking photos and your memory card is full, but you don't have another with you. Or perhaps you took some photos that you know you don't want. Deleting a handful of files from the camera can be tempting, but is that a smart move?

With modern cameras and cards, the biggest risk with deleting files in-camera is accidentally getting rid of files you actually want. After all, the displays on cameras are small, so it's hard to tell the difference between images. It's also challenging to see fine details that may help you determine if an image is a keeper. You're better off uploading your photos to a computer and selecting which ones you want to keep, then.

While card manufacturers used to caution against deleting photos straight from your camera, citing concerns about their competence with managing a file system, that's less of a risk with modern cameras. If you only ever manage your photos through the camera's UI, you may eventually run into issues, so do so sparingly if you're extra cautious. But deleting the occasional batch of photos from your camera in between formats should be fine.

Instead of deleting files one by one using the delete button on your camera, you're better off formatting your memory card. You can do so by finding the 'Format' option in your camera's menu. Formatting your card resets the file structure and reduces fragmentation. It essentially restores the card to a clean, original state for new data, which helps prevent any file system errors. Keep in mind, though, that formatting a memory card will wipe all data. Only format your card after you have safely backed up your files.

It's also important to format the card only in the camera you'll be using it in, not on a computer or a different camera. Formatting a memory card in the camera rewrites the file structure and prepares it for files from that specific device. Using a card formatted by a different device can risk file system corruption or card errors. It may also cause compatibility issues, resulting in the camera not writing files at all.

If you have a card that's acting up, or you want a truly clean slate, you may want to do a deep rather than a quick format. A deep format irretrievably deletes all the data, but puts more wear on your SD card. There's not much reason to do it unless it's a last-ditch effort to save a card that's having issues after a regular format, or to make sure sensitive images are gone for good.

It's smart to format your card after each shoot (or each time you transfer files) simply to make sure you don't accidentally delete photos that you haven't backed up. There's no worse feeling than going to transfer images you thought were on the card, only to realize you formatted it before copying the files to the computer. Formatting regularly can help minimize the risk of errors, but the bigger benefit is helping you keep track of all of your images.
