The name Leica carries considerable cachet for many photographers, regardless of whether they've ever had a chance to shoot with one of the company's rangefinders or used one of its lenses. The fabulous cost and continued adherence to a near-obsolete, manual-focus, rangefinder design can be off-putting, making it easy to wonder whether the brand's proponents have bought into marketing or mystique. So just what is it like to shoot with an M9-P? We put the camera in the hands of four photographers with different backgrounds and shooting styles to see what the 'red dot' meant to them.

Accessory maker LockCircle has announced it will offer its 'LockPort' durable HDMI socket bracket for the Nikon D800. The LockPort800 combines a mounting plate that secures to the base of the camera with a miniHDMI-to-standard HDMI adapter that bolts onto it. This provides an easy-access full-size HDMI connector while also protecting your camera's miniHDMI socket from damage. The mounting plate is designed so that the camera can still be used with other mounts, tripod plates and accessories, in tandem with the LockPort. The LockPort800 will be available from June 2012 at a cost of $199/€99.

Nikon has confirmed to PDN that it is investigating a problem that can cause the D800 and D4 to lock-up while shooting. The company says that the issue - identified while PDN was reviewing the camera - can be avoided by disabling Highlights and RGB Histogram on the display. At present the lock-ups require the battery to be removed to restart the camera but PDN thinks it likely that Nikon will be able to come up with a permanent fix.

Bag maker Think Tank has announced an update to its Airport series of camera bags. Designed to meet the restrictions imposed by airlines on carry-on luggage, the series includes a model designed for international flight as well as smaller versions for space-limited short-haul flying. The three bags are all designed with room for an iPad and increasingly large laptops, and give clear indications of the camera bodies and lenses they will accommodate. All three come with a seam-sealed rain covers.

Just posted: Pentax K-01 studio sample shots. We're in the process of running a production K-01 through our studio tests, so wanted to present the results of our standard test scene. The K-01 fits a lot of the excellent K-5 into a somewhat avant-garde mirrorless body. Retaining a similar 16MP APS-C sensor to the K-5, we expect great things from it, in terms of image quality, so does it live up to those expectations? Raw shots corrected following the discovery of a processing error.

The ever-inquisitive Roger Cicala at LensRentals has dismantled a light-leak-fixed Canon EOS 5D Mark III and compared it to an unmodified version. The solution, as proposed by every tool-shed tinkerer, appears to be a piece of black electrical tape, which Cicala says successfully stops stray light reaching the camera's metering sensor. When asked if he'd send his own Mark III back to be modified, Cicala points out that he doesn't 'do long exposure night photography with autometering.' But, in the unlikely event that you do, you can rest assured that Canon can fix your camera for you.

Adobe has released the finalized version of Adobe Camera Raw v6.7, the last update that will work with Photoshop CS5. The final version include support for Canon's EOS 5D Mark III, Nikon's D800 and the Olympus E-M5, as part of a list of 21 cameras added. The update includes the most recent NX cameras from Samsung as well as coverage for a range of Fujifilm models. No support is yet included for the Fujifilm X-Pro1, however.

Software maker Visual Supply Co has created the VSCO Cam iOS camera app, to go alongside its 'VSCO Film' film simulation software. The $0.99 app works with both iPhone and iPad cameras, offering ten filters and a series of simple editing tools, including Grain, Fade, Contrast and Fill Light. It also makes it easy to share the images via social networks. Unusually, the app applies its filters to the pre-compression camera output. The company's blog features a selection of images taken on the launch day of the app, to give a taste of what its users can do.

DxO Labs has updated DxO Optics Pro to v7.2.3, adding support for the Canon EOS 5D Mark III and Pentax's K-01. The latest version includes 70 camera and lens combination modules for the 5D III and 26 for the Pentax K-mount mirrorless camera. As usual, a 30-day free trial of the software is available.

Joel Sternfeld was one of the photographers that pushed for the acceptance of color photography in fine art and documentary photography. Adam Koplan looks at a 'First Pictures,' a collection of his early work (1969-1980) and how it foreshadows his work that was to follow.

Slovakian startup 84.5mm has announced it range of filters for photography and cinematography. The company's name is a reference to the size of its filters, which are designed to be compatible with Cokin's 'P' filter holders. Initially 84.5mm will offer a series of predominantly handmade ND Grads and colored filters, made from CR-39 (often called 'organic glass').

Luminous Landscape has published an interesting article by former NASA captain Alan Poindexter about photography in space. Poindexter commanded the penultimate mission of the space shuttle Discovery in 2010, and had been lead photo/TV crewmember on previous missions. In the article he provides a unique perspective on the challenges of taking photographs in space.

We've just posted our review of the Olympus OM-D E-M5. The E-M5 is the first in a line of OM-D Micro Four Thirds cameras, featuring an electronic viewfinder and resembling the company's classic OM line of SLRs. It boasts a 16MP Four Thirds sensor and a '5-axis' image stabilization system, wrapped-up in a compact, weather-sealed magnesium alloy body with a tilting rear screen. It's also one of the most customizable cameras on the market. So does the range-topping camera live up to Olympus' promises? Click here to find out.

Triggertrap has announced a mobile app that converts your iPhone into a highly-configurable remote release for your camera. It works in concert with two hardware components, a 'Mobile Dongle' that connects to the phone plus a suitable camera cable, to offer a wide range of methods to release the shutter. These include timelapse, distance lapse (based upon the phone's GPS), face recognition, and sound, motion, and shock detectors. It can also control High Dynamic Range bracketing up to 19 exposures. A free trial version of the app is available for evaluation purposes. The full app and Mobile Dongle each cost $9.99, and are available now from the iTune App Store and Triggertrap web shop respectively.

We've just posted our hands-on preview of the Nikon D3200 entry-level DSLR. The D3200 builds on the the company's line of simple, accessible beginners' DSLRs by adding a higher-resolution screen, boosting its continuous shooting rate and adding details such as a microphone jack and infrared remote sockets. And then, of course, there's the 24MP CMOS sensor, making it by far the highest pixel-count camera in its class. Our preview builds on the samples gallery we posted earlier this week and includes our standard studio test shots.

Just published: Jeff Keller's in-depth review of the Panasonic Lumix DMC-ZS20 (TZ30 outside the US). The ZS20 is the slimmest 20x zoom camera on the market, with a lens covering a 24-480mm equivalent range and featuring the company's latest Power O.I.S stabilization. The 14MP high-speed MOS sensor allows the ZS20 to autofocus in as little as 0.1 seconds, and shoot at up to 10 frames per second (5fps with AF-tracking). It also has GPS and an updated mapping function to show photos on a map with greater detail. The ZS20 can capture 1080p60 movies in AVCHD or, in an interesting step for one of the creators of AVCHD, it can shoot 1080p30 in MP4 format.

Adobe has released a second Release Candidate version of Lightroom 4.1, its Raw conversion and asset management software. The latest version adds support for 13 additional cameras, including the Nikon D3200, Olympus E-M5, Pentax K-01, Ricoh GXR A16 24-85mm and the three latest Samsung NXs. Interestingly, it also adds an improved 'defringe' option to reduce axial chromatic aberrations. A series of blog posts by Adobe explains the latest changes.

Canon has made the latest firmware (v1.1.2) for the EOS 5D Mark III available from its customer support websites. The update fixes a number of small bugs and adds compatibility with the GP-E2 GPS receiver. The file can be downloaded from your region's Canon support website.

We've just received an updated Fujifilm X10 featuring the revised, orb-resistant sensor, announced in March. We've rushed it straight into our studio to see how it performed, alongside the existing X10 we had been putting through our review process. We'll be doing more in-depth testing, to check whether the changes Fujifilm have made have had any other impact on image quality but, given the interest surrounding the issue, we thought we'd show our preliminary results. (Updated with image quality comparison)

Nikon has announced a voluntary replacement scheme for a sub-standard batch of batteries for its 1 V1, D7000, D800 and D800E cameras. EN-EL15 batteries with an E or F as the 9th character of their serial numbers are at risk of overheating and becoming distorted, though the company says no customers have yet reported the problem. Nikon says it will replace any battery from the affected batch (which only became available after February 29th 2012).

We've prepared a samples gallery using the D3200 - Nikon's latest entry-level DSLR. While many of the features are familiar from the D3100, the latest model incorporates a 24MP sensor, so we thought we'd see what the pictures look like. Given the kind of user it's aimed at, we decided to see what the D3200 could do using the 18-55mm F3.5-5.6 VR II kit lens, at a various of ISO settings and in different lighting conditions. Click here to see how it performs.

Fujifilm has updated the firmware of its X-Pro1 high-end mirrorless camera and the three X-mount lenses that go with it. The updates make a series of changes, including a promise to reduce the aperture 'chattering' that has been common when using the camera. It also adds parallax-correction of frame lines to the optical viewfinder in manual focus mode, along with a series of bug fixes.

We've just launched a redesigned and improved on-site search feature. The search system, currently in beta, is designed to give more relevant results from all of dpreview's editorial and forums content. We've also redesigned the way results are presented, to make it easier to get to the information you wanted. We're looking for user feedback during the beta process to help fine-tune the system and how the results are provided, so there's a 'Feedback' link at the top of every results page, to let you report back to us.
