We just posted a review of the Pentax K-5 II, which also covers its near-twin the K-5 IIS, a version of the camera that lacks an AA filter for higher resolution (in theory). Offering 16MP CMOS sensors, a unique shake reduction system, and a rugged weatherproof body, the Pentax K-5 II and K-5 IIS are compelling little cameras and in this review we'll explore their various standout features, as well as look at the difference in image quality between the two models.

Pentax has announced a white version of its WG-3 rugged waterproof camera and an entry-level point-and-shoot compact. The white version of the WG-3 shares all the features with the existing model but comes in a different color scheme (we'll let you guess what that is). We'll be testing the GPS version of the WG-3 as one of our forthcoming waterproof camera tests. Meanwhile, the 'Efina' is an inexpensive 14MP CCD-based camera that's exactly the sort we thought Pentax had stopped making. Still, it comes with decorative patterns on it, which seems to be this season's thing - so that's something. The Efina, announced in Japan in January, will cost around £80, while the white WG-3 will retail for $299/£289.

After that, photos you take on your camera will automatically be sent to your mobile device. For more on the Eye-Fi Mobi, read the full story on Connect.

Roger Cicala of Lensrentals has published a blog post in which he gives his first impressions of the new Carl Zeiss 32mm F1.8 'Touit' lens, in Sony E-mount. Unlike Roger's normal approach, where he exhaustively tests multiple samples of the same lens, he was only able to look at a single example of the 32mm F1.8 on the Sony NEX-7. Click through for some details of his findings, and a link to the full article at the lensrentals blog.

Zeiss has announced that its first two Touit lenses for mirrorless cameras are now available for sale. The 12mm F2.8 wideangle has been designed according to the 'Distagon optical concept', and has an RRP of €920 / US$1,250 excluding VAT. Meanwhile the Planar-type 32mm F1.8 normal lens will cost €670 / US$900 excluding VAT. The lenses will be available to fit Sony NEX and Fujifilm X-system cameras, and include autofocus but lack optical stabilisation. The X-mount versions also feature aperture rings with 1/3 stop detents. The next model in the line, a 50mm F2.8 Macro, is expected to appear at the end of the year.

Hot on the heels of its cashback offer for its 1 System cameras, Nikon UK has announced similar promotions on its D600 and D5200 SLRs. Buyers will be able to claim back £50 / €60 on the D5200, and £150 / €180 on the D600, when purchased either body only or with a new Nikkor lens. Meanwhile buyers of various Coolpix compacts will have the chance to win one of over 1200 'exhilarating prizes', including an indoor sky diving experience.

The Tamrac 5592 Big Wheels SpeedRoller 2X is a serious camera bag, featuring an industrial strength telescoping handle, oversized wheels fortified with ball bearings, and of course loads of space for camera equipment plus a 17-inch laptop. Despite an impressive capacity the SpeedRoller 2X is small enough to carry on to airplanes. It's not cheap though, at a street price of around $400. Do you get what you pay for?

Another interesting patent has been discovered by Japanese blogger Egami, which shows a new method devised by Canon to adjust the shape of meniscus lens that seems different from the more straightforward method used by competitors. Canon's method uses the same 'electrowetting' principle as existing designs but does so to create a series of pumps, allowing faster and more precise control over the resultant lens.

It seems the Chicago Sun-Times is counting on its remaining employees to become mobile photographers. After laying off its entire 28-person photography staff yesterday, the newspaper has announced mandatory training for remaining employees on 'iPhone photography basics'. That's according to media writer Robert Feder. Feder quotes a memo from managing editor Craig Newman: 'In the coming days and weeks, we'll be working with all editorial employees to train and outfit you as much as possible to produce the content we need'.

The organisers of Europe's largest annual photographic trade show, Focus on Imaging, have declared that this year's show was the last. Mary Walker Exhibitions had organised the show, held in March at the National Exhibition Centre in Birmingham UK, for the past 24 years. In a statement Mary Walker announced that the rights to the show would not be sold on, but instead it is simply being brought to an end.

We've had a chance to take another look at an 'initial production' Olympus PEN E-P5, and have updated our preview with some more first impressions and image samples. Olympus has only allowed us to publish downsampled images, but we've still been able to get more of an idea of how well the camera works. We hope to get our hands on a production E-P5 that we can use to shoot full size images towards the middle of June, but until then click through for our updated preview to whet your appetite. 

ACD Systems has announced the latest version of its ACDSee photo management and editing software for Windows. ACDSee16 gains a range of editing and organizational tools, including features that simulate out-of-focus regions and tilt-shift lens effects. The latest version is available at a reduced price ($50), for a limited time, with existing users being about to upgrade for $30. A 15-day free trial is available from the company's website.

According to a report in the Chicago Tribune, the Chicago Sun-Times has laid off its entire photography staff, and plans to use freelance reporters and photographers in the future to save costs. The layoffs, which are believed to take effect immediately, were announced to the 28-strong photo staff on Thursday morning. In a statement issued by the paper, it suggested that the move was in response to a demand for 'more video content' from its audience. Click through for more details. 

Nikon UK has announced a summer cashback offer on its 1 system cameras.

Markieta has marked more than 58,000 flightpaths and the results are stunning. Click through for images (via BBC.co.uk)

Leica has announced that it has a 'new family member' coming on June 11th and, as the German manufacturer continues to tease what it's calling the 'Mini M' on its website, a photo has emerged which may reveal more details about the forthcoming camera. A French iPad app has published what seems to be an advertisement for the new Mini M and, if genuine, it reveals that the Mini M will sport a 16MP APS-C sensor and an 28-70mm (equivalent) F3.5-6.4 zoom lens. Click through for more (alleged) details.

We've just posted our head-to-head review of the Canon PowerShot G15 and Nikon Coolpix P7700.

DxOMark has tested two recently-announced announced long telezooms, the Sony 70-400mm F4-5.6 G SSM II and the Nikon AF-S Nikkor 80-400mm f/4.5-5.6G ED VR, as well as the older AF Nikkor 80-400mm f/4.5-5.6D ED VR. As part of our ongoing collaboration we've added the test data to our lens comparison widget, and to add a little more context we've also included a couple of super-tele primes from Canon. Click through to see how these lenses compare, with links to view the results in our lens widget, and for the full data on DxOMark.

Canon has posted a firmware update for its EOS-1D Mark IV and EOS-1Ds Mark III full-frame DSLRs to allow them to work correctly with the new EF 200-400mm F4 L IS 1.4x lens. Firmware versions 1.1.3 (1D Mark IV) and 1.2.2 (1Ds Mark III) allow the cameras' central AF points to achieve focus with the lens when it is used with an extender, where the combined aperture is F8. Both updates are available for immediate download. 

Canon has announced that it has now produced 90 million EF lenses since the launch of the EOS system in 1987. The proliferation of digital SLRs has seen a rapid increase in lens production in recent years, and the company's 90 millionth lens - an EF 24-70mm f/2.8L II USM - was manufactured on May 23 2013, just over 9 months after its 80 millionth. The company's lens lineup currently consists of no fewer than 84 models, ranging from the inexpensive EF 50mm f/1.8 II to high-end exotica such as the recently-announced EF 200-400mm f/4L IS USM Extender 1.4x - the world's first SLR lens with a built-in switchable teleconverter.

Samsung has published the source code for its NX300 and NX2000 mirrorless cameras - the first attempt we've seen at offering public access to a mainstream camera's operating system. The approach, which the company has previously used with its smartphones, stands in stark contrast to other camera manufacturers, which have not engaged with the community of programmers looking to enhance the capabilities of their cameras.

David Akerman, a ballooning hobbyist based in England has been working with the Raspberry Pi Foundation to use their products for high-altitude photography. Using a Raspberry Pi computer hooked up to the company's new camera module, Akerman created a lightweight 'eye in the sky' that he recently sent up to more than 120,000 feet above the United Kingdom.

In a brief note on its Japanese website, Sigma has announced that the Sony and Pentax mount versions of its highly-regarded 35mm F1.4 DG HSM 'Art' lens will go on sale on 31st May. It's also announced that the Nikon-mount version of its 120-300mm F2.8 DG OS HSM 'Sports' telephoto zoom will be available at the same time. We gave the 35mm F1.4 our Gold Award when we reviewed it back in December, for its combination of exceptionally good optics and solid build at a price rather lower than the camera manufacturers' equivalents.

Video sharing service Vine has generated a lot of buzz in recent months. Vine allows you to share videos of up to six seconds in length as either a single continuous take or as a 'collage' of short duration clips. Art Director Jethro Ames saw Vine as a challenge and decided to push his limits to see what he could do with the app. The result is a series of imaginative timelapse videos that are perfectly executed down to the last detail. Click through to see his work, and our interview on connect.dpreview.com.

Canon has patented a color-sensitive multi-layered sensor design, showing the company is still pursuing the technology. Like Sigma's Foveon chips, the multi-layered design allows each of the sensor's pixels to capture color information without the need for colored filters. The patent, discovered by the Japanese Engineering Accomplishment blog, suggests a system to promote resonance within the sensor, in an attempt to make the lower layers of the sensor more sensitive.

Leica has placed a teaser on its Facebook page for a new 'Mini M' camera to be launched on June 11th, that apparently will slot into its range between the M rangefinder and the X2 fixed-lens compact. It's given no other details, but we think it could make sense for the company to produce a full-time live view version of the M Typ 240, using the same sensor but with the expensive rangefinder assembly removed. This would result in a 24MP full frame mirrorless camera that would be able to use almost any manual focus SLR or rangefinder lens ever made, without a field-of-view crop. 

If you've never had the chance to stand in the front row and shoot a live concert, Montreal-based photographer Pierre Bourgault has the next best thing. He attached a GoPro camera to the top of his Canon DSLR and recorded a seven-minute video of his shooting experience at a Dead to Me concert. He then overlaid the actual photos taken at the show, which you can view after the break.

Fujifilm has updated the firmware for its X-Pro1 and X-E1 mirrorless cameras, to improve the autofocus speed with the recently-launched XF 55-200mm F3.5-4.8 R LM OIS telephoto zoom lens. Versions 1.05 for the X-E1 and 2.04 for the X-Pro1 are available to download from the Fujifilm website. Click through for the links.

We've just added three studio comparison pages to our previously-published preview of the Pentax MX-1. The MX-1 is Pentax's flagship compact camera, and something of a departure for the manufacturer, offering a fast F1.8-2.5 zoom lens, full manual control and a high-class, metal body, to compete with more established peers like Panasonic's LX7. Click through to go to the new pages in our preview, and see for yourself how the MX-1 compares to its rivals.  

We just published the DxOMark Mobile Report for Samsung's new flagship smartphone, the Galaxy S4 on connect.dpreview.com.

Animated flipbooks have been around for nearly 145 years. With just a little thumb action, these books allowed you to view a few seconds worth of animation. Now, a new concept camera known as the Gifty allows you to record video and print a flipbook instantly. The only problem: you can't buy one yet. 

Much of the fallout surrounding Flickr's massive updates this Monday continues to center around the legacy 'Pro' accounts and a contentious statement from Yahoo CEO Marissa Mayer: 'There’s no such thing as Flickr Pro today because [...] there’s really no such thing as professional photographers anymore.' She apologized today for her 'misstatement', and it appears that existing Flickr Pro account holders will still be able to take advantage of unlimited storage. Read all about it at connect.dpreview.com.

If you've ever wondered who to thank (or blame) for those 8-bit animated graphics that remain prelevant even on today's high-bandwidth Internet, Steve Wilhite is your man. He was honored for that achievement at this year's Webby Awards and took the opportunity to once again remind us how 'GIF' should be pronounced. (via New York Times)

We've just posted our review of the The Olympus PEN Mini E-PM2. The E-PM2 is an entry-level Micro Four Thirds system camera, with a 16MP CMOS sensor and full 1080 HD video. It's one of the smallest mirrorless cameras on the market and boasts 8 frames per second continuous shooting.

Just posted: Our review of the Tamron SP 24-70mm F/2.8 Di VC USD. In our latest lens review produced in collaboration with DxOMark, we look at Tamron's fast standard zoom for full frame cameras - the first in its class to include optical stabilisation. With its Ultrasonic Drive focus motor and drip-proof construction, it looks like a very tempting option for full frame shooters, especially as it costs rather less than its counterparts from Canon, Nikon or Sony. But is this all too good to be true? Click through to read our review and find out.

Our friends and collaborators over at DxOMark have recently been looking into how lenses score on specific cameras, and the latest model they've examined is the Nikon D600. In a three-part article published at the end of last week, they investigate how 70 lenses from Carl Zeiss, Nikon, Samyang, Sigma, Tamron and Tokina measure up on the D600's 24MP sensor.  The article also compares how given lenses score on the D600 compared to the 36MP D800 and 24MP D3X.

Flickr fans may find the lure of a free terabyte attractive, but they might be put off by the accompanying advertisements that support Flickr's new free account model. A major update to the photo sharing service has completely revamped the look of accounts and restructured the way users may pay for Flickr in the future. We take a look at the changes on connect.dpreview.com.

A cover image in the latest issue of the New York Times' monthly style magazine, T, has led to an interesting discussion about the newspaper's policy on photo retouching. While editors forbid any image manipulation beyond, 'minor color-toning and brightness' in news stories, retouches and removal of blemishes are allowed in the style magazine's fashion photography. Does a newspaper risk credibility by allowing retouching on editorially-branded content? Click to read more and share your thoughts.

Lindsay Adler and Erik Valind, both working professionals and educators, have written a beginner’s guide to photographic lighting with an unusual conceit at its core. By structuring a book around a list of common challenges - what they call the 'top ten worst situations' - they've created a digestible, useful 'lighting 101' guide. In this short review, Adam Koplan takes a look at their book 'Shooting in Sh**ty Light: The Top Ten Worst Photography Lighting Situations and How to Conquer Them'.
