The M.Zuiko Digital 40-150mm f/2.8 PRO lens was first announced at the same time as the OM-D E-M1 camera, when Olympus revealed it was developing two new high-performance lenses and establishing the M.Zuiko PRO lens category.

Regular 'consumer' zoom lenses have a variable maximum aperture, but pros demand a constant f/2.8 lens with consisting top-drawer performance – and Olympus has produced exactly that.

Olympus is making a big splash with the new Olympus 40-150mm ƒ/2.8 Pro lens. No longer are professional and enthusiast photographers beholden to their large, heavy DSLR telephoto zooms if they want a tele lens with bright apertures, rugged weather-sealed build quality and compatibility with...

The Olympus M.Zuiko ED 40-150mm f2.8 PRO ($1,499.99) is a serious lens. It covers a longer telephoto zoom range then the standard pro 70-200mm zooms when paired with a Micro Four Thirds camera, and is incredibly sharp from edge-to-edge throughout the entirety of its range, even at f/2.8.

Edge-to-edge sharpness throughout zoom range; No distortion; Protected from cold, dust, and splashes; Excellent close focus capability; Innovative collapsible hood; Manual focus clutch system; Includes tripod collar

Pricey; Lack of optical stabilization an issue for Panasonic Micro Four Thirds shooters

The Olympus M.Zuiko ED 40-150mm f2.8 PRO ($1,499.99) is a serious lens. It covers a longer telephoto zoom range then the standard pro 70-200mm zooms when paired with a Micro Four Thirds camera, and is incredibly sharp from edge-to-edge throughout the entirety of its range, even at f/2.8. You don't see that type of image quality every day, and there's even a dedicated 1.4x teleconverter available for purchase if you need a longer reach. The 40-150mm lives up to its PRO moniker, running circles around the budget-friendly M.Zuiko Digital ED 40-150mm f4.0-5.6 R ($149.00 at Amazon) in every conceivable way save for size. It's because of this that we're not only bestowing Editors' Choice accolades on this top-end telezoom, but we're going as far to give it a 5-star rating. Those don't come often, but there are a lot of reasons that this lens is deserving. The 40-150mm ($1,349.00 at Amazon)  is huge when compared with other lenses designed for the Micro Four Thirds system, but fairly c...

The Olympus M.Zuiko ED 40-150mm f2.8 PRO is the perfect telezoom for Olympus Micro Four Thirds shooters, even though Panasonic owners will be turned off by its lack of in-lens stabilization.

"I've own many micro four thrids lenses since adopting the system. I'll be honest, some haven't met with my expectations. While many lenses in the system are superb by any measure, a large number are what you might call consumer-grade glass good, but not acceptable for professional work by today's...

This lens is excellent for portrait, street, sports and landscapes. For a lens of this range, it is compact, beautifully balanced and light weight compared to equivalents used on full frame or APS-C DSLR's.
