The barrel of the OM System 40-150mm f4 Pro is mostly metal. The exception is that, when the lens is extended, the piece that protrudes from the barrel is plastic. There’s also a bit of plastic around the front of the lens and the lens hood is plastic.

Close focus is a very close 2.3 feet (0.7m), which gives it a reasonable 1:5 maximum magnification. Panasonic body owners need to know that this lens does not have image stabilization; it relies on the camera body to stabilize shots. Weighing in at 760 grams without the included tripod adapter, the Olympus M.Zuiko Digital ED 40-150mm f/2.8 Pro telezoom is exactly as heavy – or lightweight, depending on where you stand – as the widely-known Canon EF 70-200mm f/4L IS USM lens, while covering a wider angle-of-view range and offering a full-stop brighter relative maximum aperture. may not be utilized, directly or indirectly, to inform, train, or improve any artificial intelligence program or system. I shot with this lens in the cold and light snow. And then, since I didn’t think the light snow was really up to IP53 standards, I put it under the faucet. The lens continued to function normally, including smooth turns on both rings. I also didn’t detect any debris on the sensor after shooting with this lens. It’s fair to say this has been a highly anticipated lens, seamlessly continuing where the 12-40mm stops, and delivering an 80-300mm equivalent range that’s desired by close-range action as well as street and portrait shooters. Now with two lenses, Olympus can take you from an equivalent of 24mm all the way to 300mm with a constant f2.8 focal ratio throughout, and while the 40-150mm is obviously one of the larger lenses in the catalogue, it remains compact for a lens for its class. As well as superior optics and performance, the Pro tag denotes high quality construction with an all metal body that is dust, splash and freeze-proof. The lens also comes with a removable lens collar for tripod mounting, as well as a collapsible lens hood.

Intro

There isn’t much else to say in conclusion except that which I said at the start: the 40-150mm is a wonderful lens. Along with having great optical performance and a versatile zoom range, it is also an important step forward for a system that is becoming more and more mature and complete with solutions that can suit amateurs, enthusiasts and professional photographers.

The 40-150mm f/2.8 M.Zuiko Digital is one of what Olympus refers to as their “pro” m4/3 lenses. Beyond the obvious main specification—which would be 80-300mm (equivalent) with a “fast” aperture—the lens has other features that are found in Olympus’ “Pro” lineup, including a Splash Proof designation.With the lens attached to an Olympus E-M5 camera body, focusing is incredibly fast. The subject typically pops into focus within the blink of an eye – very impressive. In good light you will even find the C-AF performance respectable, if not quite on a par with a pro SLR. A word of warning though – if you have face detection AF enabled on the E-M5 and you are not focusing on a human subject, the auto focus system becomes slower, less decisive and sometimes downright confused. So make sure to switch face detection off whenever photographing something other than a person. This may only apply to selected camera models though – it is entirely plausible that this problem won't arise when shooting with an OM-D E-M1, for instance.
