But, while many manufacturers will label a lens as weather-sealed but not say exactly how much weather is too much, OM System has added an official IP rating to this lens.

it’s a lens that compliments the build quality of the E-M1 and manages to feel at one with the camera. I've not played with this enough yet to determine what the crossover point would be for when I would be better served making a crop on the bare lens with an 2 stop advantage. of course that may not be a bad thing – obliterating a background through a shallow depth of field can be fun, but comes at increased risk of missing the focus or only having part of your subject looking sharp.

But it is also true the M43 has advantages over FF, and in many circumstances, it’s possible to get comparable image quality – particularly when extended depth of field is required or theirs an opportunity to take advantage of M43s superior IBIS.

Both focusing and zooming are fully internal, meaning the lens' optics adjust within the constraints of its outer barrel, so the length of the lens remains the same regardless of zoom and focus settings. Its optical design makes use of a series of aspherical and low dispersion glass elements to suppress chromatic and spherical aberrations for notable sharpness and clarity, and a ZERO coating is also used to reduce flare and ghosting for high contrast, color-accurate imaging. focal ratio on both lenses means they’ll share the same exposures, their relative depth-of-field is quite different, with the Olympus lens actually being equivalent to a 80-300mm f5. So a fairer comparison in terms of what you can actually achieve in terms of reach and depth-of-field may be something like Canon’s EF 70-300mm f4.

The Olympus lens is more light-weight and compact just as promised by the MFT marketeers but about as expensive despite the smaller image circle. Removable rotating tripod collar offers a stable platform for working with this lens atop a tripod or monopod. Sometimes the combination performed brilliantly, but at other times lacked confidence and could hunt back and forth. Don’t take the time to do that, and you’ll probably accidentally take the hood off instead of sliding it.

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. I will more than likely use the wide-angle lenses for overall scenes and the wife will use the 40-150mm 2. Professional lenses are always expected to be able to survive a bit of a battering from those it’s used by, and there’s nothing to suggest the M. Some farmers are demonstrating a very good sense and taste for coloring the landscape by interspersing sunflowers.aperture, so you won't have the nice background blur or subject isolation nor the same low light performance. For many shots, the 40-150mm locked-onto subjects quickly and without fuss, but for others it struggled, especially with faces in lower light conditions. Zuiko Digital ED 12mm f/2 lens: pulling the focus ring backwards exposes a useful distance scale and allows you to use the Olympus M. The zoom ring motion is as smooth at its widest focal length as it is at full telephoto and offers a pleasing fluid motion that I found just a fraction stiffer than AF/MF focus ring.

as measured from the sensor plane The shot below demonstrates how close you can get to the subject – in this case, a Compact Flash memory card. Sure the Olympus rendering was a little creamier, but the depth-of-field at typical portrait distances was fairly similar in appearance, plus of course if you can step back a little further, you could shoot with the Leica at 200mm f4 where the overall look becomes even closer. for the OMD EM1 which, amongst other things, promised greater focusing accuracy with the 40-150mm lens. As you’d expect there’s a rotating tripod collar, and that collar can be removed if you’re going to handhold the lens. It attaches to the front of the lens via an inner mechanism and a quick-release ring allows you to twist and push back the hood for storage, without having to detach and reverse-mount it.

At close range with the lens zoomed-in, you also have a shallower depth of field to deal with than most lenses in the Micro Four Thirds system, so it’s not surprising to experience more hunting when the going gets tough.
