Panasonic has announced the Lumix S 40mm F2, a small, fast lens for L-mount that recalls its much-loved 20mm F1.7 prime for Micro Four Thirds.

The lens gives a fractionally-wider-than-normal field of view on full frame sensors and has been designed to match the dimensions of the 18-40mm F4.5-6.3 kit zoom for the S9, in its retracted, carry-around state.

Panasonic described it to us as "more of a muffin lens than a pancake."

The $400 lens features seven elements in six groups, with three of those elements being aspherics. Its relatively modest price results in a 7-blade aperture design, but despite this, sees seals deployed at all the key points around the lens to provide dust, splash and freeze resistance down to -10°C (14°F).

Likewise, while Panasonic has avoided the cost of including a lens hood (and the costs of designing one to match it), it's made sure to include a lens function button on the side of the barrel. The focus ring has the usual options to control focus throw and focus direction, or act as a control ring.

The S 40mm F2.0 weighs just 144g (5.1oz). It accepts the same 62mm filters as the 18-40mm and its front element has a fluorine coating.

The 40mm F2 will be available from Early June at a recommended price of $399, exc sales tax.

We've been shooting with the 40mm for a while and, even paired with an S1RII, found it plays a big part in making the camera/lens combination more carryable.

While a distortion correction profile is embedded in the lens, and we've applied it to the images in the gallery, its effects are extremely subtle. The lens is not utilizing high levels of correction.

Software company DxO has announced the ninth iteration of Nik Collection, its suite of seven creative editing plugins. Nik Collection 9 introduces updated masking tools and new filters for photographers looking to add creative finishing touches to their images.

The most notable update is the addition of more advanced masking tools via the Local Adjustments toolbar. In Nik Collection 8, DxO added the ability to import Photoshop's AI-powered selections (such as Select Subject), but otherwise, selection tools remained rather simple and required direct user input. Now, the company has added AI-powered masking to Nik Collection apps, no Photoshop or manual selections required.

The updated AI masks come in two different forms. First, users can select subjects and objects, just like they can in Photoshop. There's also the new Depth Mask option, which uses AI to create a depth map, allowing users to make adjustments to specific areas based on the distance from the camera. Because it's AI-powered, it works without embedded distance data from the camera.

Both types of masking rely on local processing, so images stay on the user's computer. They can be fully adjusted and fine-tuned as needed. To aid with that, DxO added new Mask Overlays that make it easier to see where a mask is. Masks can also be copied and pasted from one filter to another, saving time from having to reselect that same area for a different adjustment.

Nik Collection 9 also features three new filters. The Chromatic Shift option recreates the look of ink misalignment from magazine days, with full control over the direction and level of shift and the colors shifted. The Glass Effect filter makes it look like your subject is behind a sheet of textured glass, and the Halation filter aims to replicate the look of the glowing highlights characteristic of certain film stocks.

DxO is also giving users more control over how those filters interact with the image. It has added 18 different blending modes to Color Efex and Analog Efex, which will be a familiar option to Photoshop users. There's also a new Preset Hover Preview option, providing instant, real-time previews of presets without clicking back and forth between the options.

Lastly, there is now a color grading menu, which keeps all color controls in a single color wheel. Users can select three points for highlights, shadows and midtones, adjusting the color of each area. Additionally, a slider below the color wheel shows the color grade from shadows to highlights and allows users to shift all tones at once.

DxO's Nik Collection 9 is available for download now. It costs $180 for a new perpetual license, or $100 for those upgrading from Nik Collection 7 or 8.
