Cons: The tube for tele seems very light build and moves far out, but nothing to complain about. If mounted the hood, there is no chance to change or rotate a filter attached.

Pros: well build and good balanced, acceptable fast autofocus, sharp pictures and low distortion, shipped with lens hood and lens bag and two caps

Summary: It's a kit lens but still worth more than that. It's acceptable fast, is sharp and has an acceptable bokeh for such a lens and it's also a good opportunity to attach macro converters for stunning macros.

Cons: A little on the large size for a micro 4/3rds lens. And, of course, it would have been better if it was the same size and price and f2.8 all the way. : )

Pros: Sharp, smooth and well built. Uses 52mm filters which are cheap to buy and the same size thread as the commonly owned 14-45/42mm lens.Comes with a nice shade too--buy a Canon or Nikon lens and you have to cough up another $30-$40 for the shade.

Summary: This is a very sharp lens and my shots at the 200mm end (400mm equivalent) are better than expected with little the way of softening. The boket is reasonably good too when taking a portrait and zoomed out about half-way. No harsh blobs just a nice blurry background that does not distract. I recommend this lens and for the price paid it is fabulous value--especially given its quality and the fact that it is MIJ. I moved from a Canon 70-300mm IS and would say the Panny lens is a step up all round--especially at the long end.

Cons: slow, I have to shoot on a bright day.

Pros: light, small and cheap! Picture are very good and sharp, if not super sharp as other panasonic lenses: 20mm and 45mm lenses.

Summary: for a zoom up to 400mm for $270 at that small and light, what I can complain?? If you shoot bright day and with shutter faster than 1/400, you will get excellent sharp images! Very happy with this lens.

Cons: not a fast large aperture lens

Pros: Instant to focus on latest Panasonic bodies Superb tight build, very smooth zoom and nice balance. Size just can't be beat for focal length provided

Summary: This is, to me, one of the "must have" mft lenses. It is lightweight but tight and solid built. Pretty much instant focus lock and is consistently accurate. The price is absurd for what you get. I've had a Canon 100-400L that was $1400 that didn't look better in print than what this lens delivered. Makes for the ideal addition to your travel lens group

Cons: Slow in all respects and at longer focal lengths impractical to use in anything other than bright light. The light weight and small size is deceptive and tempts you to take it out without a tripod, which is usually a mistake. Nothing outstanding in terms of sharpness either.

Pros: Appears solidly built and is easy to carry around.

Summary: Disappointing and the worst Panasonic purchase I've made. Very little to commend it in my opinion, although I seem to be in a minority amongst users. Priced competitively and perhaps if I tried it out more often I'd be able to work more effectively within its obvious limitations.
