Resolution Chart Comparison EOS 5D Mark II vs EOS-1Ds Mark III
Shots here are of our new 'version two' resolution chart which provides for measurement of resolution up to 4000 LPH (Lines Per Picture Height). A value of 20 equates to 2000 lines per picture height. For each camera the relevant prime lens was used. The chart is shot at a full range of apertures and the sharpest image selected. Studio light, cameras set to aperture priority (optimum aperture selected), image parameters default. Exposure compensation +0.7 EV to +1.3 EV.

From the crops on the previous pages, we could predict the results of this comparison. These two full frame Canon cameras with 21 megapixel sensors produce the same amount of resolution on our test chart.

On the resolution chart, the Sony A900 shows the value of all those pixels in pure resolution terms, and is still the highest resolution DSLR we have ever tested. The 5D Mark II comes in a very close equal second (with the 1Ds Mark III). In truth there's no practical difference in the resolving power of these three cameras, though there are slight differences in the 'per pixel' sharpness and the amount of sharpening applied to JPEGs.
Given that the 5D Mark II 's high ISO performance - seen elsewhere in this review - is almost as good as the D700, and visibly better than the A900, the 5D Mark II offers a combination of resolution, sharpness and ISO performance that is hard to beat.

DPR regular Steve Badger says that there's 'no excuse to be bored' when there's a camera at hand. His love of photography began when he borrowed a friend's superzoom, and eventually invested in a DSLR system. His home on the east coast of Australia provides plenty of spectacular scenery, but he's eager to travel and grow as a photographer. See gallery
Canon has updated its Digital Photo Professional 4 (DPP) software to version 4.1.50. The update brings support for a couple of new lenses and several camera models, improvements to multiple functions, and compatibility with 64-bit native environments, among other things. The newest version, says Canon, incorporates feedback from both APS-C and older full-frame owners eager for 'the very latest Raw workflow solution'. Read more
A multimedia journalist by trade, Tim Matsui's still photography projects have taken him from native Alaskan villages to Brazilian Air Force training facilities. Matsui shares with us his journey in creating his latest documentary work, from its beginnings in still photography to the adaptations he made to turn it into a video production. Learn more about his work on 'The Long Night,' a documentary debuting this week that looks into human trafficking in Seattle. Read our Q&A
'What's in your bag?' is a question we ask a lot of photographers, because, well, we're nosy that way. Asking the very same question, photographer Thom Atkinson posed it (figuratively) to centuries of British soldiers. He's assembled what would have been the belongings and clothing of a dozen combatants, ranging from medieval to modern-day soldiers. Take a look and learn how it all came together in our Q&A.

George Probst has been fascinated with sharks his whole life, but it wasn't until he found himself newly single with some extra money in savings that his dream of diving with and photographing sharks became a reality. He hopes his photos will inspire others to see sharks in a light unlike their typical portrayal in movies and pop culture. Find out about his process and see his work. See gallery
The Prvke Lite is the latest release from camera bag/strap maker Wandrd. A shrunk-down version of their popular full-sized Prvke bag, this model is perfect for smaller kits, including mirrorless cameras.

The Panasonic Lumix DC-G100 (G110 in some regions) is a mirrorless camera designed for vlogging. Its 20MP Four Thirds sensor is paired with clever tracking audio technology, but we have our reservations.
The GFX 100S fits most of the capabilities of the GFX 100 into a smaller and more affordable body. We've tested what the camera offers to see who it might make sense for.
The Sony Alpha 1 is Sony's flagship mirrorless camera for, well, just about anything. With a 50MP sensor, it gives you tons of resolution, but it also lets you fire off burst images at 30 fps for fast action sports. Add in 8K video capture and you have a really impressive package.
