The larger APS-C format of the Samsung NX10 goes up against the Micro Four Thirds system of the Panasonic Lumix DMC-G2 as we test two micro-system cameras in our Panasonic Lumix DMC-G2 vs Samsung NX10 camera test

Panasonic Lumix DMC-G2 vs Samsung NX10 – Autofocus

Contrast detection is the order of the day with these two cameras. Given that this is a slower way of focusing than the phase-detection method used in DSLRs, both the NX10 and Lumix DMC-G2 perform extremely well and are surprisingly fast. There has been some debate on various online
forums about whether the Panasonic or Samsung AF system is faster. In single AF mode, I would say that the G2 is noticeably faster, although in practice it makes very little difference in most situations. Compared to the NX10, the G2 is also faster and smoother when focusing in continuous AF mode.

The G2’s AF system has a number of other features, the first of which is AF Tracking. This allows a subject in the scene to be targeted by the AF point, and then tracked as it moves within the frame. For moderately fast-moving subjects, such as people walking or running, this speeds up the process of focusing the camera.

Another great feature of the G2 combines the fast focusing with the touchscreen. The appropriately named Touch Shutter mode allows the user to simply press the touchscreen at the point at which they wish to focus. The G2 responds to this touch and quickly focuses the lens and fires the shutter. In my initial review I was very impressed with just how quickly this process took place.

In low light, both cameras find focus quickly, and both have AF assist beams on the front of the body. These beams are coloured green in the NX10 and red in the G2, and they illuminate the scene slightly so that autofocusing can take place. In low light, the Live View display signal of the G2
is amplified. This allows the user to see the display better, but presumably the amplified image also helps to detect contrast so the AF can work. This could be why it is slightly faster than the NX10, but again the difference in speed will mean little in most situations.
