Sony today announced three new "muffin" lenses for full frame Alpha cameras: the 24mm f/2.8G, the 40mm f/2.5G, and the 50mm f/2.5G. "Muffin" refers to a compact lens size that is not exactly pancake (near flat), but one that is about the size of a small muffin (a fist full).
All three of the new compact lenses are close to the same exact size, cost US$599, and include lens hoods (plus the lens cap fits on the hood, too).
