As expected, Apple revealed iOS 7 today at the 24th annual World Wide Developers Conference, and there's plenty for mobile photography enthusiasts to be excited about. From photo filters built into the Camera app to better automatic organization within the Photos app, we take a look at Apple's forthcoming revamped mobile operating system and what it will bring to photographers on the go.

We've just published our first impressions of shooting with the Sigma 18-35mm F1.8 DC HSM | Art lens. We've tried to express just why we're so excited about this lens, which offers APS-C DSLR users access to some of the depth-of-field and low-light capabilities that full-frame shooters get from their F2.8 zooms. We're hoping to hear about pricing and availability soon so, in the meantime and in the light of our first impressions, what would you expect to pay for this lens?

Swedish camera manufacturer Hasselblad is finally shipping the 'Lunar'. This 24 megapixel camera - essentially a rebadged Sony Alpha NEX-7 - was announced at Photokina last year and comes with your choice of grips: black or brown leather, carbon fiber, and wood: mahogany or olive, to be precise. The Lunar includes an 18-55mm lens and is priced at $6995/£5280.

Photographers and star-gazers in the upper United States were treated to a rare display of Aurora Borealis when the 'Earth passed through a region of south-pointing magnetism in the solar wind,' according to spaceweather.com. More aurorae are expected in the late hours of June 8 or early June 9, with NOAA forecasters estimating a 65% chance of geomagnetic storms. Click through for images and more details.

A new app asks users to step back into the darkroom as it offers digital equivalents of the developing process. Koloid is inspired by 19th century's wet-plate collodion photography. The app creates a unique texture and exposure on a black and white image. Koloid takes a little longer than most camera apps but it also gives the satisfaction of using something other than a one-touch filter. We give it a go on connect.dpreview.com.

Rumors are flying about a supposed Nokia EOS smartphone that would surpass even the 41-megapixel Nokia 808 PureView model. Reports indicate that the 'EOS' will sport the same size sensor that made the Nokia 808 so remarkable. Photos of a purported EOS prototype also show a similar raised camera profile as the 808. See what other speculations are likely by clicking through to connect.dpreview.com.

Following the widely-reported layoffs at the Chicago Sun-Times a former Visual Editor at the paper, Robb Montgomery, has written a thoughtful piece for CNN.com about what the decision to move to a freelance work force means for the paper, and the industry as a whole.

Just posted: Our review of the Nikon Coolpix A. With a 28mm-equivalent wideangle lens, and the same 16MP DX format sensor as used by the D7000 SLR, the Coolpix A is designed as a serious compact camera capable of professional-quality results. But it's up against stiff competition, in the shape of the similarly-specified but cheaper Ricoh GR that was announced a month later. In our 16-page comparative review, we take a detailed at how the Coolpix A measures up to the challenge posed by its close rival.

Just posted: Our hands-on preview of the Canon EF-M 11-22mm f/4-5.6 IS STM. Canon's third lens for its EOS M mirrorless camera is its first image-stabilized wideangle zoom, and first with a collapsible barrel design. With an 18-35mm equivalent angle of view and silent STM focusing, it could be an interesting option for photographers wanting the wider view but looking to travel light. Click through for our first look.

Tokina has announced a US price of $599 for its AT-X 12-28mm F4 Pro DX lens. Soon to be available in both Canon and Nikon mounts for APS-C bodies, this lens was announced at the CP+ tradeshow back in January and will replace the company's existing 12-24mm F4 wideangle zoom for APS-C cameras. 

Capturing the perfect panorama shot with a smartphone can be tricky. A new gadget currently gaining ground on Kickstarter could help you achieve a perfect panning motion, and even aid in motion time lapse photography. Spinpod works with both iOS and Android devices, as well as cameras. See it in action on connect.dpreview.com.

In advance of Apple's World Wide Developer's Conference next week, we're sharing our photographer's wishlist of the announcements we're hoping to see from the annual event. Compare our thoughts with yours on an expected new iOS 7 mobile operating system, whether or not we'll see a new iPhone and more at connect.dpreview.com.

Canon has announced the EF-M 11-22mm f/4-5.6 IS STM - an image-stabilized wideangle zoom for its EOS M mirrorless camera. It's Canon's first wide zoom with IS, promising three stops of stabilization for stills and 'Dynamic IS' for video. A linear stepper motor offers silent autofocus during movie shooting, and a retractable barrel design makes the lens about the same size as the 18-55mm kit zoom. It should be in shops at the end of June, at an MSRP of £379.99 / €399. A firmware update for the EOS M (v.2) will give full compatibility with the 11-22mm, and faster autofocus with all lenses.

For nearly forty years, photographer D. James Dee has documented artwork and installations for seminal artists like Jean-Michel Basquiat, Julian Schnabel and prominent New York City galleries. He's now closing up shop and faces the prospect of finding a home for roughly 250,000 color slides and negatives that chronicle the explosive growth of the Soho art scene of the 70s, 80s and 90s. So far he's found no takers. Is this trove of recent art history headed for the dumpster? Click through to read more. (via The New York Times)

If you've ever spent any time as a self-employed photographer, you've no doubt heard countless rationales from clients about why you should work for free, or at least lower your rate. PhotographyTalk.com posted a pitch-perfect list of five classic lines that not only ring true to those of us on staff with freelance backgrounds, but would be perfect punchline setups in an Aaron Johnson 'What The Duck' comic strip. Click to see if any of them sound familiar. (via PhotographyTalk.com)

We've been lucky enough to get our hands on an early pre-production sample of one of the most anticipated lenses of the year, the Sigma 18-35mm F1.8 DC HSM, and bring you a gallery of full-resolution sample images shot with it. This lens is the fastest zoom ever made for SLRs and, in principle, should provide the depth-of-field control and low-light image quality on an APS-C DSLR that you'd get using an F2.8 zoom on 35mm full-frame. We've shot a samples gallery including a variety of subjects, using a range of apertures, focal lengths and subject distances, to try to give an initial flavor of how the lens performs.

The HTC One smartphone made headlines with its claims about 'ultrapixel technology,' which the company used to describe the device's 4MP CMOS sensor. While current competitors boast 8-13MP cameras, HTC is betting on fewer, larger pixels a same-sized sensor to offer better image quality. But does the innovative approach work? We've put the HTC One and its ultrapixels through our rigorous real life and studio testing trials to find out. See how it fared at connect.dpreview.com.

Scientists at Bell Labs have built a prototype camera that uses no lens and a single-pixel sensor. This idea is based around a grid of small apertures that each direct light rays from different parts of the scene to the sensor, and can be opened and closed independently. The sensor makes a series of measurements with different combinations of open apertures, and uses this data to reconstruct the scene in front of the camera. No lens to focus the resultant image means infinite depth of field and low cost. Click through for more details and a link to the original research. 

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. Click through for a link to the full review.

Rob Hart was amongst the 28 members of the Chicago Sun-Times photography staff laid off last week. He's been pointedly documenting his experience via Tumblr ever since, deliberately opting to use his iPhone over his Nikon D3 because, as he says of himself in his blog, he was "replaced with a reporter with an iPhone, so he is documenting his new life with an iPhone, but with the eye of a photojournalist trained in storytelling." We spoke to him about it for connect.dpreview.com.

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? Read our review to find out.

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'.

Japanese company Amulet is poised to release a 'Wise Duo' CompactFlash card allowing images and video files images to be backed up instantly using RAID-style 'mirroring'. In mirroring mode, the card effectively becomes two storage devices, and records images to both partitions simultaneously. As such, a 64GB card offers 32GB of storage space in mirroring mode. Click through for more details.

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.

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.

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.
