The Olympus Pen EES-2 stands out with its zone-focus system, allowing more control over focusing compared to the fixed-focus of its predecessors. It features a 30mm f/2.8 lens similar to the Pen EE-2 but with the added advantage of manual focus control. Its combination of manual focus and automatic exposure makes it a versatile choice for those who want a bit more control without the complexity of a fully manual camera.
