Leica is on the verge of launching a new compact camera as one of its most affordable models. A leak of the V-Lux20 shows it to be an upscale version of Panasonic's Lumix ZS7 with the same 12X, 25-300mm zoom. The point of reference would dictate the built-in GPS, 12-megapixel sensor, HD video recording and three-inch preview LCD.
