One could speculate that the Lumix X 14-42mm lens does not create any dust problems when zooming, as the rear element, facing the sensor, is not moving back and forth at all. This is contrary to the older Lumix G 14-42mm f/3.5-5.6 lens, in which the rear element moves forward when zooming in. The rear exit pupil of the lens is stationary, even when the lens extends, and during zooming. This is perhaps a bit counter intuitive, as it needs to extend again before being ready after waking from the sleep mode.įinally, if you connect the camera to a computer, and turn it on to transfer files using the USB cable, the lens will extend, even when the camera is in file transfer mode. When entering power save mode, the camera will collapse the lens. If you accidentally turn on the camera while it is in a bag, with no room for the lens extension, then the camera notices this, and gives up, leaving the lens unextended. The Sigma 30mm f/2.8 EX DN, for example, has a start up delay of three seconds, even though it has no extending section at all. Hence, there is always a two second delay before you can use the camera. The lens extends when you turn on the camera. There are two levers on the side, one for focus, and one for the power zoom: However, in this case, the older Lumix G 14-42mm lens has the shortest focus distance at 42mm, which would enable you to photograph smaller images at 42mm with the older lens. Generally, one gets the largest magnification in the longest tele setting. However, this applies only at f=14mm, and the distance changes in tele mode: From the table, the newer X lens has the shortest minimum focus distance, which looks all well. This is not a very large difference, but it shows that in terms of aperture, the newer X lens generally gives you a smaller aperture opening.Īnother specification item which is quite misleading is the minimum focus distance. At f=25mm, the difference is about 1/3 stop. It reaches f/5.6 already at f=32mm, while the older Lumix G 14-42mm lens reaches f/5.6 at f=42mm, the longest end. This tells us that the newer Lumix X 14-42mm collapsible lens has a smaller maximum aperture for all intermediary focal lengths between the wide and long end. ![]()
