If you're looking for some new glass to go along with your E-mount NEX camera, Sony has two new options for you to consider tonight.
The 20mm F/2.8 pancake lens is a totally new lens that earns the "pancake" designation with a total length of just 20mm. Because the NEX cameras use APS-C sensors, it has a full-frame equivalent coverage of a 30mm lens. It's made up of 6 elements in six groups. And in addition to its small size, it also weighs just 2.4-ounces, which might be less than an actual pancake depending on which diner you go to.
The 20mm F/2.8 Pancake will be available in April for $350, while the 18-200mm F/3.5-6.3 OSS will cost $1,200 when it becomes available in March. At that pricepoint, you're definitely still paying for those video specific features, so if you're looking for a dedicated still lens, it might be overkill.
