Like the Tamron, the Olympus 40-150mm Zoom ring is located toward the front of the lens. But unlike the Tamron, the Olympus’s zoom ring is much too tight to roll with my outstretched index finger. Would nevertheless be interested on seeing what the performance is like with the co-released 1.4x converter. Any plans to test that?[/quote] The only other control is a lens function button to which you can assign one of many functions, such as one-shot white balance, focus peaking, and a focus limiter. However, the functions available depend on your camera, not the lens. I wish the zoom ring were a little lighter so I could rotate it with my outstretched index finger. It would be cool if the teleconverter were built in, but that’s asking a lot on a lens in this price range. Seriously, that’s all I can think of. Olympus 40-150mm F2.8 Compared

If you take the same lens with the same aperture and focal length and take the same photo with both full-frame and µ4/3rds cameras having the same pixel size, they will have identical depth of field! What surprised me was the performance of the E-M1/40-150 in low-light. Aside from dance show, I also decided to test the lens for the Electric Run 2014 where people participate in a non-competitive marathon at night wearing fluorescent and brightly-lit clothing. I was curious to see how the lens would behave in such a difficult situation where even other photographers with DSLR cameras were having a hard time. Surprisingly the camera and the lens worked really well and I only really found myself in trouble when the scene had a too little contrast or almost no light. 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.

Other attributes: The Olympus cameras perform distortion and aberration corrections in JPEGs, and some raw converters do, as well, so it’s getting a little more difficult to talk about such issues for a lens than it used to. If you’re shooting JPEGs, I’d say don’t worry about either. Olympus’ correction doesn’t take out all chromatic aberration in the extreme corners, but it takes out enough that most people would just ignore what does get produced. The Olympus also maintains a maximum aperture of f2.8 throughout its focal range, and again it’s very usable at this setting. At its maximum focal length of 150mm, the corner performance may not be as crisp as the Leica, but there’s no issues towards the middle of the frame and remember at 150mm the Olympus is essentially one stop brighter / faster too, allowing you to maintain lower ISOs or faster shutters.

I’ll admit that I had trouble finding something wrong with the performance of this lens. I could easily keep this chapter very short and tell you that the M.Zuiko 40-150mm f/2.8 Pro produces stunning images with great sharpness (even at its fastest aperture), bokeh, micro contrast and colour rendition. It isn’t a premium lens primarily because of its build or its price, but because of the quality it can deliver. E-M1, 1/400, f/ 5.6, ISO 200 – 190mm – MC-14 Before I move on to talk about the optics and focusing, just to note that like several other lenses in the Olympus range the 40-150mm f2.8 Pro has a L-fn function button on the barrel that can be assigned to one of a number of functions from the custom menu on the camera. Olympus 40-150mm f2.8 Pro opticsAnother very interesting characteristic of this lens is the closest focussing distance of 70cm throughout the entire zoom range. As such, you can focus at 70cm even at 150mm or when using the MC-14, since the minimum focus distance isn’t altered by the teleconverter. This expands the versatility of this lens even more because it allows you to take near-macro shots. E-M1, 1/60, f/ 8, ISO 200 Following an initial day of testing at the Cheltenham horse races with Ken McMahon, Gordon sourced a second sample of the lens and tested it for a month in a wide variety of portrait, landscape and action environments. He also retested the lens with the Olympus ODM EM1 updated to firmware 2.2 which claims to deliver superior AF precision with the 40-150mm. Read on to find out if this is the telephoto zoom Micro Four Thirds owners have been waiting for. Olympus 40-150mm f2.8 Pro design and build quality Thanks for this. I had the 50-200 SWD and used it extensively to shoot kids soccer games, where it performed quite well. However, I later got the 40-150 Pro and both MC teleconverters, and then got the 100-400. I sold my beloved 50-200 SWD kit as a result.

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. At 40mm sharpness is already outstanding in the centre of the frame at maximum aperture, although performance towards the edges falls behind somewhat, only reaching fairly good levels. Stopping down improves performance across the frame, with peak sharpness across the frame being achieved at f/5.6. Here clarity is outstanding in the centre, and very good towards the edges. Place both of the telephoto zooms side-by-side and there’s significant physical differences to literally weigh-up. The Leica is noticeably more compact, shorter and lighter. I could squeeze it into my bag standing up whereas the Olympus always had to lay down and occupied much more space. That said, the Olympus enjoys the benefits of internal zooming (less chance of dust or moisture entering the barrel) and a tripod foot for greater stability (which also sports an Arca Swiss dovetail base). Both lenses may feature lens hoods that can fold over the end of the barrel for transportation, but the Leica hood must be reversed and re-mounted, whereas the Olympus hood simply pulls-out. There’s no doubt the Olympus feels more confident and has more physical features (including a programmable function button for Olympus bodies), but again it’s much larger.In addition, the Olympus M.Zuiko Digital ED 40-150mm lens has a so-called L-Fn button, which allows users to temporarily suspend continuous auto focus when something suddenly comes between the lens and your intended subject. This is mostly useful when shooting a movie clip with C-AF enabled, but the feature can also be used when photographing action.
