High quality, light weight ultra-wide for micro four thirds systems.

Summary: I owned and used this lens extensively when I had my Panasonic GH1. It is a very light-weight but sharp "ultra-wide zoom" for the micro four thirds system cameras. This includes Panasonic, Olympus and Kodak models. There is some minor corner softness wide open but it mostly clears up when stopped down to F5.6. Very sharp in the center at all times.

Summary: This is one of my workhorses for m4/3. I bought mine 2nd hand and it was like new. Now that I have a year on this lens, I can say that it is one of my favorites. I have the Nikon 14-24 2.8 and the only advantage over the Panasonic 7-14 is that it is one stop faster. However, with that extra stop and having to cover a 35mm frame means that it is large, heavy and subject to lots of lens flare, even when the source is out of the frame.
Summary: For my first foray into DSLR I picked m4/3. I didn't know what to expect from camera OR lens so I experimented. I've seen a lot of shots on YT made using wide angle lenses and knew I didn't care for fisheye effects. This lens does some pretty wide angle shots, but the fisheye effect is there even when being careful about the lens angle. I really do like that the lens gets everyone in the frame when they're in a small room.
Summary: I've been replacing my P&S camera with Panasonic Lumix 4/3 camera with 20mm lens and have been really happy with it. Then one day, I happened to chat with my friend whom is a photographer. He recommended me this lens. When I came home, I searched on Amazon and after reading the reviews, I purchased this right away and have been really happy with it. The lens focuses quickly, built quality is great, lightweight and most important, the pictures turned out beautiful.
Panasonic 7-14mm f/4 ASPH LUMIX G VARIO review by LowTEC
7 June 2014
Summary: Simply say, I love this lens. This lens is one of the sharpest UWA lens I have ever used, and I have used Nikon 14-24mm, Canon's, Tokina, and Oly M.zuiko 9-18 It is compact but relatively front heavy for smaller M4/3 cameras, it is decently sharp wide open, and corner to corner sharpness at 7mm f5.6. Build quality is excellent with nicely damped zoom ring (although I only use 7mm range).
Pros: SHARP, corner to corner sharp
Cons: lack of filter mount, purple blob issue with E-M5, E-PL5, GH3
