The first major upgrade of a Pentax DSLR under the Ricoh brand brings us the innovative K-3. This 24 megapixels APS-C DSLR is based on a high-speed CMOS sensor capable of 8.3 FPS continuous shooting at full-resolution. It can also capture full 1080p HD video in realtime or a 4K Ultra-HD time-lapse.

The K-3 inherits the Pentax Shake-Reduction mechanism which brings unique Automatic Horizon Correction and Composition Adjustment, plus ads yet another completely new feature: an Anti-Alias Filter Simulator. This, for the first time, gives photographers the choice between maximum sharpness and potential moire artifacts.

Pentax K-3 Review

Ricoh Pentax K-3

 

Neocamera just published their most extensive review to date for the Ricoh Pentax K-3. As always, we cover features, usability, ergonomics and performance in great depth.  A special page compares in great details the K-3 vs last year’s the K-5 IIs, for those considering to upgrade. In addition to the usual full-resolution gallery an 100% crops, this review includes a comparison of APS-C and Full-Frame performance. Be sure not to skip anything! Read it all here.

Now that CMOS sensors are incredibly common, even on ultra-compact cameras, many digital cameras can quickly capture multiple frames to produce a single image which cannot be captured in a single shot. Even if the camera cannot do it, software exists to combine multiple images together in different ways.

An exposure is what happens in the camera from the time the shutter opens to the time it closes. Most images are produced from a single exposure which takes a slice of time and dynamic-range and captures it. By taking multiple exposures and combining them, one can produce an image which shows more than what an exposure can capture.

Multiple images can be combined in a number of ways:

  • Panorama Stitching – This produces an image with a wider field-of-view than any individual image can, up to 360-degrees actually.
  • Exposure Fusion – This averages out pixels from different exposures to produce directly a low-dynamic-range image, so there is not need to do the tone-mapping like for HDR images. Tone-mapping is the delicate operation where, without a subtle hand, you end up with the types of images you are talking about.
  • HDR Blending – This takes images from multiple exposures to produce an image which stores more dynamic-range than what the camera can normally capture. These images are often used in 3D rendering to make simulated reflections more realistic.
  • Focus Stacking – Takes images focused at different distances to produce and image with an impossibly deep depth-of-field. Often this is used for macro photography to show entire subjects in focus.
  • Image Stacking – This is one most often used with astrophotography. This creates a long exposure by adding up short ones. You would need to take 525 consecutive exposures and the Image Stacking software will blend them into one.
  • Multi-Frame Noise-Reduction – Averages a number of images to produce one which is less noisy. This can also be used for astrophotography to reduce the noise in long low-light exposures.
  • Multiple-Exposure – Overlays multiple images to artistic effects. This is what layer-blending in Adobe Photoshop essentially does. It shows images as if they were super-imposed.

Note that you can combine techniques which requires even more images. For example, to produce an image which captures a wide dynamic-range and infinitely deep depth-of-field, one may use 5 shot brackets at each focus distance. With 5 such distances, one would need 5 x 5 = 25 shots.

Some artists take this to the extreme by using different combinations of multi-exposure techniques for foreground, middle-ground and background elements and then blending the results together which is yet another similar technique. Images combined from hundres of exposures have been produced!

A ground on Kickstarter is building a digital camera which can take full 360 degree spherical images in a single shot merged from 4 lenses. It can capture 14 megapixel images and 1080p HD video which can be streamed live via WiFi.

The very compact Bublcam, as it is called, has roughly the size and shape of a baseball. A tripod sockets lets it shoot without the photographer in the scene and it stores its images on a small MicroSD card.

Funding ends on December 14th, so hurry up if you are interested in being among the privileged first owners. The good news is that the project already reached its initial goal and so this Bublcam is likely to become a reality soon.

Every year, Neocamera chooses the best digital cameras for each category and type of photographic subject. The 2013 set of Best Digital Cameras was just published. Those not sure what to buy can easily find a great camera among those. Every chosen cameras is the most outstanding model currently available in its respective category.

Unlike last year which had a big shake-up, 2013 introduced plenty of minor upgrades and a good number of models kept their top spot from 2012. The biggest area of growth was among mirrorless cameras which got upgraded and took on new markets. This made 2013 an exciting year for advanced photographers who want quality and performance with less bulk than a DSLR.

For professional photographers, 2013 is a turning point where a high number have decided to go mirrorless, either as a main or as a backup system. With the advent of the Olympus OM-D E-M1, mirrorless cameras offer all high-end photographic features, including a sturdy weather-sealed and freezeproof body.

The recently-reviewed Nikon 1 AW1 also became the first – and currently only – waterproof interchangeable lens camera. With a suitable lens, it can be submerged 15 meters underwater or dropped from 2 meters high.

This year manufacturers concentrated on delivering fewer models than before, while aiming at the mid-to-high segment of the market. 2014 is most likely to continue that trend but we also expect to see several top-of-the-line DSLRs as flagship cameras are starting to show their age.

This year our publication of the Best Digital Cameras of 2013 is later than usual because so many high-end models have just arrived. We have several reviews in progress, so stay tuned for detailed reviews of the Pentax K-3, Nikon D610 and Fuji X-E2 to be published soon!

Neocamera just reviewed the Panasonic Lumix DMC-GX7. This mirrorless is the first from Panasonic with built-in image-stabilization. Its relatively compact body includes a tilting 2.8 megapixels EVF and 3″ LCD screen. With a rich feature-set, the GX7 is incredibly capable and versatile.

Panasonic Lumix DMC-GX7

The new Panasonic flagship is one of the fastest Micro Four-Thirds cameras around. Its mechanical shutter offers speeds up to 1/8000s and continuous shooting up to 5 FPS. The 16 megapixels CMOS sensor behind it boasts a wide sensitivity range from 125 to 25600 and outputs full 1080p HD video at 60 FPS.

Read the review to see how this camera measures against the competition. The comprehensive review covers capabilities of the GX7, evaluates its usability and analyzes its performance. As always, a gallery of full-resolution images at 100% crops at all ISOs are provided for readers to judge image-quality for themselves.
