Sony adds to its E-mount lens line for the Alpha NEX series of cameras with a 20mm f2.8 pancake (30mm equivalent) that will ship in April for $349.99. Sony currently only offers one other pancake lens, a 16mm f2.8 (24mm equivalent). From a size standpoint, the pancakes are a nice complement to the skinny NEX bodies, but you'll usually get better image quality --and faster apertures -- out of their not-so-slim counterparts.
Sony also took the opportunity to announce standalone pricing and availability for the 18-200mm f3.5-6.3 power zoom E-mount lens that it unveiled as part of theat last fall's Photokina. It will ship in March for $1,199.99.
