Panasonic Lumix GX9 offers 20MP with no low-pass filter, improved shutter mechanism

13 Feb

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_3796470565″,”galleryId”:”3796470565″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Panasonic is taking the wraps off the GX9, a 20MP Micro Four Thirds camera. Its sensor does not use a low-pass filter in an effort to maximize sharpness, and a new L/Monochrome D Photo Style is on board for fans of black-and-white film. The GX9 does not offer weather-sealing, unlike the GX8 and G9.

The GX9 offers a 2.7 million-dot (equiv.) EVF that tilts 90° upward, and a 1.2 million-dot touchscreen that tilts up 80° and down by 45° – a departure from the G9 and GX8’s fully articulated screens. An electromagnetic drive claims to reduce shutter shock by 90%, an attempt to mitigate the shutter-induced softness we saw in previous GX- models.

The camera relies on contrast detect autofocus with the help of Panasonic’s Depth from Defocus technology when Panasonic lenses are used. Naturally 4K/30p/24p video is present with all of the affiliated 4K Photo Modes, including two new ones: Auto Marking and Sequence Composition. Auto Marking allows the camera to identify movement in a 4K clip and set a marker to quickly jump to the action, and Sequence Composition makes it easy to create composite images of action in-camera.

In-body 5-axis stabilization combines with dual-axis optical stabilization, resulting in a claimed 4-stop reduction in shake. Wi-Fi and Bluetooth are available for quick image sharing.

The Panasonic Lumix DC-GX9 will ship in the beginning of March with a new 12-60mm F3.5-5.6 kit lens for $ 999. An optional wide eyecup ($ 19) and grip ($ 59) will also be available.

LUMIX GX9

The Ultimate Compact Single Lens Mirrorless Digital Camera Capture High Quality Images in Your Own Creative Way

Newark, NJ (February 13, 2018) – Panasonic is proud to introduce the LUMIX GX9, a sleek, compact new Digital Single Lens Mirrorless camera for everyone who wants to shoot vibrant, true-to-life, high quality images in their own creative way with excellent resolution, high contrast and impressive color reproduction.

The LUMIX GX9’s 20.3-megapixel Digital Live MOS Sensor without a low-pass filter and Venus Engine combine to drive maximum lens performance while rendering natural, high-precision images. The L.Monochrome D mode is newly added to Photo Style, making it easy to shoot detailed dynamic monochrome photos with emphasized highlights and shadows. Plus, Grain Effect can also be adjusted in all monochrome modes with Photo Style.

A 5-axis Dual I.S. (Image Stabilizer) in the LUMIX GX9 effectively suppresses blur. Combining an O.I.S. (Optical Image Stabilizer, 2-axis) and a B.I.S. (Body Image Stabilizer, 5-axis), the Dual I.S. compensates for a wider range of movement to enable blur-free photo/video shooting from wide to tele, even in low-light conditions.

A new wide screen LVF (Live View Finder) in the LUMIX GX9 tilts up approx. 90 degrees. With its high, approx. 2760k-dot equivalent, resolution and 100% color reproduction, this 16:9 LVF provides approx. 1.39x / 0.7x (35mm camera equivalent.) magnification and 100% field of view. Plus, the camera’s large 3.0-in., approx. 1240k-dot high resolution static-type touch monitor provides nearly 100% of field of view tilts up approx. 80 degrees and down 45-degrees to enable shooting in high or low angle even easier.

The Contrast AF System in the LUMIX GX9 features DFD (Depth From Defocus) technology and excels in both speed and accuracy by exchanging digital signals between the camera and the lens at max. 240 fps*1, for ultra-fast auto focusing in approx. 0.07 sec*2. A range of extensive AF functions include Face/Eye Detection AF, Pinpoint AF, One-shot AF and advanced Low Light AF to enhance usability to comply with various shooting situations. Live View Boost makes it possible to check composition even in total darkness by boosting sensitivity just for live view.

The LUMIX GX9 records smooth, high-resolution 4K video in 3840×2160 at 30p or 24p in MP4. 4K PHOTO is easier to use in more creative ways with Auto Marking and Sequence Composition, two new additions to Post Focus, Focus Stacking, Light Composition and 4K Live Cropping.

Ultra HD 4K video and 4K PHOTO

With a high-speed sensor signal readout and engine processor, the LUMIX GX9 records smooth, high-resolution 4K videos in 3840×2160 resolution at 30p or 24p in addition to the Full-HD 1,920×1,080 60p videos with practical full-time AF. With this technology, LUMIX 4K PHOTO lets users capture perfect moments by extracting single frames from 4K burst files shot at 30 fps to save as 8-megapixel equivalent photos.

Choosing the best shots out of hundreds of 4K video frames is now easier with a newly added Auto Marking function. Auto Marking identifies the frame most different from others in the file to help minimize the time it takes to choose the best individual shot. A Sequence Composition function creates a stromotion image in-camera by synthesizing multiple images shot at fixed frame to produce a unique image of a subject’s motion without special retouching.

The LUMIX GX9 also includes Post Focus, a function selects an in-focus area even after shooting. Post Focus is helpful in situations such as macro shooting where strict focusing is required or for changing expressions by changing the focused subject. This capability combines high-speed, high-precision DFD (Depth From Defocus) auto focus technology and 4K technology. A Focus Stacking function adjusts depth of field after shooting by combining multiple images shot with Post Focus in the camera. Now users don’t need to focus strictly while shooting because they can create images with the defocus level they want or pan-focus simply by selecting the focus area after shooting — beneficial when shooting macro images of insects, small accessories and so on.

LUMIX GX9 also incorporates a Light Composition function, a new 4K PHOTO option. The camera synthesizes images by choosing and saving a brighter pixel to easily produce more dramatic images of fireworks or night scenery in-camera. What’s more, the LUMIX GX9 also enables 4K Live Cropping in video recording to realize stable panning or zooming. In panning shots, users just set the viewing angle to begin and end with for smooth panning imagery without using special equipment like a slider. And in zooming, users can set the after-zoomed viewing angle firs to ensure the subject is perfectly in the frame. The imagery of zooming is smooth because it does not move the zoom lens physically.

The LUMIX GX9 includes Bluetooth and Wi-Fi® connectivity for a more flexible shooting experience and instant image sharing with easy operation. Compatibility with Bluetooth 4.2 (Bluetooth Low Energy) enables consistent connection with a smartphone or tablet with minimum power consumption.

Sharp thinking: Nikon creates selectable strength low-pass filter

30 Aug

shared:NikonLogo.png

Nikon has patented a technology that can adjust a camera’s low-pass (AA) filter based on the situation. By using an electronically controlled liquid crystal panel, the AA filter can either be turned on and off, or set to ‘normal’ or ‘high’ intensity. The first design would allow for a D800 that become a D800E at the push of a button. The second design would have a mild anti-aliasing effect for stills, and a stronger effect to reduce moiré in movies. More details on this exciting development after the link.

11 Sep

pentax_k5ii.png

Pentax Ricoh has announced its latest flagship DSLRs – the K-5 II and K-5IIs. The ‘s’ version, which costs $ 100 more, comes without an anti-aliasing filter, to offer higher resolution at the risk of more prominent moiré interference patterns. Both cameras feature 16MP sensors and the weather-sealed magnesium alloy build of the original K-5. The biggest difference is the latest, SAFOX X, autofocus sensor. This is designed to work in lower light than any of its rivals (down to -3EV) it will also provide greater accuracy when working with F2.8 and fast lenses. The K-5 II will be available from October at a cost of around $ 1350 with 18-55mm WR kit zoom. The K-5 IIs will be available, body-only for around $ 1300 – a $ 100 premium over the standard version.
