Olympus M.Zuiko Digital ED 40-150 mm F4-5.6 Lens, Telephoto Zoom, Suitable for All MFT Cameras (Olympus OM-D & PEN Models, Panasonic G Series), Black

Product Information

I have neither the Leica 50-200 nor the Oly 40-150 Pro, but I have had some experience using similar focal lengths for shooting kids soccer games. When they were young, my cheap 40-150 R was sufficient to capture the field, but when they got older, it was too short (because the fields got bigger). I tried the Pana 45-200 but didn't like it that much. I ended up with the 4/3rd ZD 50-200 SWD + EC-14. With or without the teleconverter, this lens is the winner. I chose it primarily because the 40-150 Pro would have been too short, and adding the MC-14 would have made the high cost even higher (four years ago when it was new). The used 50-200 SWD was much less expensive, and gave me great results with my EM1. With the EC-14, I could reach across the field, as they got bigger. When you shoot with the Olympus 40-150 f/2.8 Pro Lens at f/2.8, you WILL be getting the light gathering of 2.8, but your depth of field will be f/5.6 in 35mm full-frame equivalence. The minimum focus distance of 0.9m is quite close for a lens with an angle of view equivalent to a 300mm lens - ISO200, 1/250, f/5.6, 150mm (35mm equiv – 300mm)

Olympus 40-150mm f2.8 review | Cameralabs

Traditionally, F4 telephoto, such as the Olympus 40-150mm F4 Pro, present a lightweight alternative to the top-end F2.8 lenses favored by sports photographers. In other words, you get the same premium optics and build quality in a lens that weighs half as much. When it gets it right the 40-150mm f2.8 produces stunningly sharp detail. This time set to S-AF mode with the light fading, but still bright enough to shoot wide open at 200 ISO with the stabilisation enabled. Again, compare that to an equivalent DSLR lens like the Canon EF 70-300mm f/4-5.6 IS II USM (notwithstanding the additional size and weight from mounting that lens to a DSLR body) and this is the smallest and lightest 70/80-300mm lens we've ever used. Regarding stabilisation, the 5-axis stabilisation of the E-M1 handled the bigger and heavier lens very well, and I managed to get acceptable results down to 1/3 of a second.Focusing on the M.Zuiko 40-150mm R was blazingly fast, and that was an impressive feat considering the lens is covering long focal lengths reaching up to 300mm equivalent. The great thing about focusing with OM-D/PEN bodies is the dead-on accuracy, I rarely find miss-focused shots, if there were any, those were probably my own fault (setting the focusing point at the wrong place, or not being fast enough to react to the subject). The focusing does slow down a little in dark shooting conditions, but still averagely fast enough without causing much impact in getting the shots done. The 40-150 is a great lens, and with the 1.4 tele converter offers you an f4 420mm equivalent, which is a pretty good length for wildlife.

40-150 F4 Pro Compared - Sensibly Compromised Olympus 40-150 F4 Pro Compared - Sensibly Compromised

For the last few years, I’ve been using my old Olympus 50-200 mm f/2.8-3.5 SWD Four Thirds lens for telephoto shots. I’ve always been pleased with its results. However, that old lens is big and heavy. This new OM System lens weighs in at a mere 0.841 lbs (381.4 grams). The new OM-1 and this lens together weigh less than the old lens with its MFT-3 adaptor attached. The new 40-150mm lens is certainly far smaller than any other lens of this focal range, and that makes it easier to use. Remember, this has the equivalent field of view of an 80-300 mm lens on a 35 mm camera. P.S. And yes I know there is a 300mm f.4 pro lens but that's just way too expensive for a non-pro like me. And I heard that the Panasonic 100-300mm f4-5.6 Mk II is not that big of a difference with the 75-300mm and is not worth the trouble switching to it. If the firmware version of your 14-150mm F/3.5-5.8 Di III [Model C001] lens is 1.0, you are required to update the lens twice. If you want even more fair comparisons, look at the cigarette stump on the ground just right from the mans head. Even when it is just partially out of focus with 40-150mm, you can see how 75-300mm will clearly render far more details in the grass blades and the stump itself! Inside the 40-150mm f2.8 Pro there are 16 elements in 10 groups including ED, Super ED, EDA and HD elements. Essentially these technologies are designed to reduce internal light dispersion (ED stands for Extra-low dispersion, EDA is Extra-low Dispersion Aspheric and HD is High refractive index & Dispersion) and improve image quality and contrast.

Quick tips

And if you can make smaller and lighter without sacrificing the image quality in the output compared to best possible product you could manufacture, it is huge benefit. But when pixel peepers and gear heads gets their hands on the product, they throw the product out of the context and just trash it or praise it.
