Excerpt: Purchased this product mostly for shooting video. If used for stills I would say that it would be fine, however for shooting video this lens is terrible. It hunts for focus constantly going in and out of focus. The only way to use this lens is in manual mode where your subject never moves.
Excerpt: Hello, I have a panny GF1 and the 20mm pancake, which I guess has spoiled me. but this new lens feels cheap and slow, it's terrible in low light, nothing but blurry photos for me, so I gave up on it, and the lens is gathering dust on my desk...
Review based on video use on BlackMagic Pocket Camera

Summary: Was delivered quickly by the seller Wild Peach. The lens was bought for use with the BlackMagic Pocket Cinema Camera. It is light as expected since it is plastic and balances pretty decently on the BMPCC.
great, light weight zoom for Panasonic and other micro four third cameras

Summary: This is a great light weight lens with in built image stabalisation, easy to change on the camera and a very good all rounder.I tend to leave this on the camera for most of my shots as it's easy to hold and light to carry around. I use this lens on my Panasonic GF3 which I love.
