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

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.ProsBuild 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.ConsLens 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.

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.

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 :/

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.

You have to ask yourself how invested in the Micro 4/3 system you are before you buy this lens. It is a really good lens. It gives good bokeh, for an Olympus lens the effective 35mm f-stop number is 5.6 (because of how the m4/3 system works compared to the full frame format). It's sharp, and focusses quickly.Against this, it's heavy, and pricy. If you've a good variety of Olympus equipment, and want a good lens to act as a very good 80-300mm f5.6 lens, then this is the best lens you can get. If you see your future going a little further in photography, most professional photographers I've seen argue there are limitations to the M4/3 format that this lens can't overcome.

I'm a previous long term Canon user but have recently sold all of my Canon gear and replaced with the the new M1 mark ii and a few Olympus pro lenses. I received the 40 - 150 lens this morning and after a few test shots the image quality is outstanding, I actually prefer this camera and lenses to the Canon Mark iii and L Lenses I've just sold... mainly because it's so much lighter, I was expecting there was going to be a trade off when switching from full frame to four thirds but after using the camera for the last few days with the 12 - 40 pro lens and today the 40 - 150 I couldn't be happier! The lens is expensive but work every penny :) Delivery was super fast too, ordered last night and received this morning, thanks Amazon! Looking forward to receiving my 7 - 14 f2.8 tomorrow.

The lens lives up to the great reviews. The AF is very quick and completely silent. I have no issues with accuracy, nails focus great. It's a bit large for the M4/3 system, but I use it like pictured - without the tripod foot and without the lens hood. It's rather compact like that, considering the long focal length and the constant f/2.8 aperture. It balances well on cameras with proper grip (pictured on E-M1 mk.II) but it's frontheavy when I put it on my smaller camera (Panasonic GX80). The pictures from it are great - sharp, with good contrast. Sharpness is very good at min and max focal length, even wide open. It's even better at f/4. The bokeh is nothing special.

This is just a great lens to have, excellent picture quality and build quality. Solid construction and weather sealed. Love the non extending zoom. easy to use and nice retracting lens hood. the zoom range is great to have particularly with the 2 x on MFT. We definitely be adding more Pro lens to the kit.
