Olympus M.Zuiko Digital ED 40-150 mm F2.8 PRO Lens, Telephoto Zoom, Suitable for All MFT Cameras (Olympus OM-D & PEN Models, Panasonic G Series), Black

Such a great lens, only had it out a handful of times but it proven to be fantastic already! Its much bigger than my other pro olympus lenses but what you you expect from a tele zoom lens at f2.8

Great lens works well with the 14 and 20 extenders.

This is a superb lens, focus is fast and accurate. Spec isn’t 100% clear, it’s f2.8 across the whole range but also can go to f22 so depth of field is never a problem. So pleased I bought it.

If, like me you have always purchased reasonable but cheaper lenses then I urge you to splash out. I use this lens on my OMD E-M5. The lens is beautifully made, very well designed, fast, a joy to use and produces images with a sharpness and clarity that I have never experienced before. At the knock-down price it is a bargain. I don't think I will ever buy another cheap lens. Highly recommended. Pros Build quality is superb and it feels as though it will take a few knocks and last a life-time. Usability is superb and it is a joy to use. The focus ring is smooth and well weighted and the ability to switch to manual focus by just sliding the focus ring is such a bonus. The zoom ring is again is smooth and well weighted. The lens is heavy but is very well balanced when attached to a camera. Sharpness is fantastic with little or no visible lens aberrations unless you look really intently at the images. Fast at F2.8 so low light and fast action shots are easier to nail. Has a separate function button (but may need a camera firmware update to be usable) Weather resistant and good in very low temperatures. Lens does not externally extend on zooming. So you don't have to lock it when on your shoulder or find it has extended on its own accord. Cons Lens hood is good and I like thew idea of having it slide down the lens, however it can drop off easily and is the only aspect that feel a little flimsy. It is heavy and fairly large so not as travel friendly. Need to invest in a heavy duty shoulder strap.

Fantastic lens. Very compact for a wide aperture telephoto, excellent mechanical quality, weather-sealed, super sharp at almost every focal length and aperture. The only thing lacking is that I would have liked a longer final focal length (even if it sacrificed a bit the minimum focal length). But this is not a defect, I knew what I was going for, and it does perfectly what it has been designed for. An Olympus with this lens mounted is soooo much smaller and lighter than the equivalent on APS-C, and, obviously, full-frame. If this M43 standard doesn't survive, it would be a great loss :/

Was so nervous when I shelled out that kind of money for some glass but wow wow wow. Total game changer in so many ways. Combined with my OMD EM1 MK 3 totally superb. Best lens I have ever owned. Makes me fall in love with photography again. A lens to silent the pixel peepers all day long. 😀

Have used this lens to photograph birds in flight and in action on a lake, really good image quality. Autofocus is very fast. Amazed how light the lens is for it's focal length. I came to Olympus recently and use an E-M5 iii with this lens. Really pleased. The lens is quite a size on the brilliantly compact E-M5 iii but when I removed the Lens tripod support ring, then it's easy to hold. I've used other manufacturers for years - clunky big lenses though good quality. Nice to have this compact system to travel and enjoy. It costs a lot, quite a commitment to pay this amount but so far the lens has performed well. Amazon delivered promptly. I was hesitant at first to pay this amount on Amazon rather than a good Camera store but went ahead during 'lockdown' and it's been fine.

Be aware the lens I received works for a few shots and then the view through the lens goes black, only the info from the camera body is visible. To rectify this I have to turn the camera off for at least 2 minutes then back on again but this fix only last for a few more shots. There is no issue with the firmware, it's up to date, batteries are fully charged, the connection between the lens and camera body is tight and secure. I do not have this issue with any of my others lenes, the return date is only 4 weeks after the purchase date so now I'm stuck trying to get it corrected. So if you buy this lens put it to use right away, hopefully you will not have the same problems but you never know.
