Excerpt: This lens is a superzoom with a focal length comparable to 28-280mm on a full size sensor. As such there is a tradeoff; weight and larger minimal aperatures vs convenience. The 14-140 is designed to be used on cameras capable of functioning very well at ISOs from 1600-6400 depending on the model its mounted on. This along with image stabilization makes it useful in many settings. It's great as an everyday lens. Teamed with a fast prime it is marvelous for travel.
Pros: Durable, Fast / accurate auto-focus, Long zoom range, Rugged
Excerpt: I bought this used from Adorama. Their ratings are conservative as I would have rated this as like new. Although I bought a Panasonic micro 4/3 dSLR to use with older lenses and adapters (Leica, Minolta et al) I kind of like the camera size and the image quality, at least in RAW, is quite good at reasonable ISOs for my personal uses.
Pros: Compact Size, Fast / accurate auto-focus, Long zoom range
Cons: Close focus distance, F56 At Most Focal Length, Poor in Low Light
Summary: This lens is one of the biggest rivals for the 14-150mm ZUIKO lens from Olympus, while also offering image stabilization that is built-in and very fast speeds of auto focusing. While it does have these advantages, the price and the weight are also bigger. The best choice would be to buy this lens together with the DMC-GH1/2 camera from the same manufacturer, as part of the kit.
Excerpt: is meant for photo not video, (i use it on panasonic af100) so it is kind of dark, and jerky to zoom, and the fact that has to extend is a bummer, sad part is supossed the best for my camera. hope panasonic makes some lenses meant for it.
Excerpt: Got this to go along with my brand new Panasonic GX1 body. Yeah it's a bit on the slow side (gets above f5 by the time you get to 50mm), but as long as you're in good light this lens cannot be beaten in the general-purpose category. Plus, pair it with a Panasonic body and distortion & chromatic aberrations are automatically corrected in-camera even for RAW output. Expensive but a winner!
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus
