Vibration reduction at work<\/i><\/p>\n

The Lumix LX1 uses two motion sensors, one for vertical and the other for hoizontal motion. These feed the opposite of any motion they detect to the lens assembly to reduce the effects of definition-robbing camera shake on the image. Panasonic calls it ‘Mega OIS’ which sounds rather grand, no? A related benefit is that with the two shutter speeds thus gained – meaning you can use 1\/15th where 1\/60th was safe before – is that ISO 100 becomes in effect ISO 400, with attendant benefits on reduced sensor noise; as I illustrated earlier, the camera’s sensor is somewhat noisy at ISO 400.<\/p>\n

Sceptical?<\/p>\n

Here are two pictures, taken seconds apart, of one of my bookshelves, hand held, taken at the longest lens setting (to emphasize shake) and 1\/4 second at ISO 100. Care to guess which one had vibration reduction switched on?<\/p>\n

<\/p>\n

I use Mode 2 OIS, meaning the OIS is switched on the moment the shutter is pressed; I have no need of Mode 1 – on all the time – as I use my glued on 28mm Voigtlander optical viewfinder to compose, not the LCD screen. And as the camera always starts with the lens at 28mm no matter where it was when switched off or powered down, there is no risk of using an optical viewfinder not matched to the lens.<\/p>\n

This wonderful vibration reduction system will add more quality to a picture than any amount spent on expensive glass without this feature. I like to think that my 28mm f\/2.8 Lumix Leica lens has just become an f\/1.4, which, in effect, it has. Anyone with a 28mm f\/2 Leica Aspherical Summicron on their Leica care to challenge me at 1\/4 second? 13″ x 19″ prints at two paces. And by the way, your competing camera and lens will have cost some ten times the price of the Lumix LX1. Too bad. Someone steals your rig and you have a problem. They can’t steal mine unless they requisition my jeans, because that’s where this little jewel resides.<\/p>\n

Oh! and did I mention the widescreen capabilty you see above?<\/p>\n","protected":false},"excerpt":{"rendered":"
