Feels a cheap because it's made of plastic and i'm afraid of it breaking so easily.. standard lens hood doesn't fit on it which is a shame. Takes beautiful photos, though it can be tough with a Panasonic body and an Olympus lens because Panasonic has OIS built into the lens and Olympus has it built into the body.. which means no OIS for this lens on a Panasonic body. Still, it can take nice photos if you mind the shake or use a tripod.

I am so glad that I picked up this camera lens for my Olympus camera. I enjoy hiking on the weekends and taking pictures of the places I go. This is perfect for that, I can easily pick between lenses because this one as well as the regular one I have are so light. It doesn't weigh you down which is great when hiking. The lens itself works great. I like the quality of the pictures I take with it and how I can get closer than I would normally get to things. It would also be great for wildlife photography when you don't want to risk spooking the animal by getting close. For the price it is well worth it.

Cheap, very light weight, and a perfect travel lens if you don't tend to shoot long but want something longer in your travel bag.

I use the old Olympus 50-200mm lens which is just a fantastic lens and one of my all time favorites. However it is a big and heavy lens. So when out family takes a vacation and I want to have a longer focal length lens on hand, this 40-150mm does the job just fine with little added weight to my gear and still offering high image quality. I normally shoot wider angle so I don't need a long focal length much while traveling, but I can carry this one along without feeling I am dragging along a brick in my backpack, which is important when walking a city all day long.

Would recommend to anyone who wants a good quality image at longer focal lengths and especially for your travel bag.

Others have said it more eloquently than I could, but I want to reiterate that this lens is completely amazing. The super-telephoto reach lets you grab those far off shots that would normally be missed, and it's also great for nature/flower photography. The slow aperture is not a big deal when shooting outdoors in decent light. The only negative is that the focusing is slow and with AF it can miss focus a lot, but I can't fault the lens for that when it costs $100!! I'll just let some recent photos I took speak for themselves. (Camera used: Olympus EM5 Mark II)

For a hundred bucks, you can't go wrong with this lens! Second to the standard 14-42 mm lens this is probably one of the most versatile lenses you can get for your camera. It lets you get close up on action and wildlife. I'm using my lens with an Olympus E-PL5 and my pictures are with no filters or attachments. It does a great job with high speed sporting photography and it is even pretty decent at closeup macro photography.

Update: I used this lens to capture the 2017 Total solar Eclipse. I was able to capture solar flares during totality. I'm really impressed with this lens for the price.
