This is a phenomenal lens, especially at the price for which it sells. I am new to the pro side of Olympus but I am thoroughly impressed by the build quality, the fluid mechanics, the relatively light weight, and the price. The lens feels like a tank in your hand but performs like an F-35. The zoom ring is smooth with no hiccups or lurching towards a certain focal point. Enough good things cannot be said about the lens, it is just a terror when compared to the similar but twice as expensive, three times as heavy 24-70s from other manufactures.

I took this as my go to lense for a Viking Cruise down the Danube. Crystal clear photos in all sorts of lighting situations with instant focus inside cathedrals and in the cities in the evening. 12 to 40 zoom range was all I needed for 99% of my photos. It’s nice to have the all metal construction when jumping on and off the crowded busses and subways.

I love this lens. I am able to get sharply-focused photos throughout the 12 to 40 mm zoom range. The lens is sturdily built and is weather resistant. The only negative I can think of is that the lens is rather heavy. But the second you pick this thing up to attach it to your camera, you’ll know that you’re holding a quality piece of glass.

Build quality, weight, size were all good. Very well matched to the omd line. Maybe too heavy for the pen series. I had to get my bundle from somewhere else. Bestbuy delayed my omd em2 twice and I couldn't wait anymore.

shoots stunning clear images, and its super fast for low lighting
