compared to:
price paid:5 USD - Auction
positive:Extremely sharp on a M43 Panasonic GH1.
Fairly well built for a "modern" lens.
Equivalent to a 200 ~ 600mm on a M43 camera.
Metal mount.
Great price performance ratio.
negative:Filter rotates with focus (bad for CPL users)
Plastic barrel.
Plastic filter threads.
A little dark (spec: 4.5~6.7)
Zoom can fall under it's own weight when pointed straight up or straight down.
comment:I bought this lens for $5 on the bay. The guy thought there was mold in the lens but is was just hair. I got it out. :) I use this lens on the Panasonic GH1 micro four thirds (M43) camera and wow (!) what a very sharp lens it is! The manual controls all work well in normal operation. The zoom is a little stiff and difficult to access (narrow zoom ring) if you intend on using this lens for video. Focusing is very smooth and easy to use (wide focus ring) but the front element rotates which could present a problem for those intending to use it with polarizing, neutral density gradient, or other FX filters.

This lens typically sells for between $100 and $200 at the time of this writing and on a M43 body the image quality (IQ) is similar to lenses costing $800 to $2,000. It has very good color rendering. I can't get any chromatic aberration (CA) out of it no matter how much I torture it. And it's sharp corner to corner at all apertures throughout it's entire zoom range.

If you're on a M43 body this makes a nice day-time birding lens but it's a little slow for birding at dusk or dawn.

It (is supposed to) come with a hood and when used there is no problem with flare. I also didn't experience any unusual flare problems with the hood off either.

In all I dig this lens! Very nice and an excellent value for the price.

(Be careful to recognize that I'm using it on a M43 camera! On a FF or APS-H it's performance and IQ may be quite different - I dunno.)
