Product Description
This high zoom ratio lens is optimized for digital SLR cameras and capable of covering a wide range of focal lengths from 50mm standard to 500mm ultra telephoto. In addition, the new super coating on each glass surface produces superb color rendition, while reducing flare and ghosting.This lens uses four pieces of SLD (the special low dispersion) glass for excellent correction of color aberration throughout the entire zoom range.This lens also features a Zoom Lock device to eliminate "Zoom Creep" when the lens is tilted down. When the lens is set to the 50mm focal length, it is remarkably compact and provides easy handling. The tripod mount is composed of magnesium, to minimize total weight and also it is easy to grip and carry the lens due to ergonomic design of the tripod mount.Non-rotating front lens elements, due to rear focus mechanism make possible the use of a custom bayonet "Petal-type Hood", which prevents extraneous light from degrading the image quality. This mechanism also allows the use of circular polarizing filters, since the front barrel does not rotate during focusing or zooming.

This is an ok lens, but I had to sell it less than 6 months later becuase it just was not up to speed with the zoom and f stops.....Trust me on this, get the canon (IS if you can afford it)a 2x if you need and you are set. this lens is OK, but why get OK when you can get amazing for almost the same price.
 Satisfied! March 7, 2008

People all say this len is great. So how great is it? Let us go cheesy and ask just one question, how sharp is it?
I recently bought the lens. Today I did a simple resolution chart test. Of course there is sample variation out there. I hope my result is typical. I tested it on my E-510. Note the maximum horizontal 'absoute resolution' of E-510 is 2100 LPH. Anything sharp won't show here. Ok here you go:
50~400mm any aperture: 1900~1950 LPH
500mm F/6.3 1750+ LPH; F/8~up 1800+ LPH
'+' mean not sure but at least.
These are all 'alsolute resolution' (where you can tell between the chart lines); 'extinction' resolution goes a bit higher, usually 250 LPH higher.
Although the sharpness is quite constant, I found the contrast clearly reduced at wide open aperture, at all focal length. One stop down it improves to good. Two stops down it gets great.
So this is quite a consistent lens however you set it! Consider it is a whopping 100~1000mm equiv on the E-510, this sharpness is quite incredible! Try find an equivalent lens in other mounts!
Heavy? Not too much for me. Work out instead of complaining guys. It is an IS lens on my E-510! I handheld it half of the time for mobility. Of course a good tripod always helps. I found the auto-focus quite fast even at 500mm on my E-510. It is quiet too. Compared to this, my Zuiko 70-300mm lens seems noisy and slow.
I am alway skeptical about Sigma lens. But there is simply not many alternatives out there. And for this lens, I am well satisfied! Now I need sunny weekends.
Sigma 50-500mm 4/3 Zoom Lens WOW! January 21, 2008

As a nature photographer, expanding into wildlife and in particular bird
photography, I was looking for a long reach lens to compliment my Olympus
E3. Settled on this one based upon reviews from various locations.
Although best use is with a tripod, the combination of this lens with the
E3's stabilization allows long distance shots from a monopod, or medium
distance shots, hand held.
It is hefty, and takes a little getting used to, but the additional strap
that attaches to its tripod collar makes for a comfortable neck carry.
The Zoom Lock is great, when you are carrying it around your neck, as
it prevents the lens from creeping out to full length, as you walk.
When used with a telecoverter, (I used a 1.4X), the directions recommend
use only from 100 - 500. You set the lock on the upper side of 100 and
it prevents you from zooming down below 100. Not sure why these cautions
are listed in the instructions, as there are no apparent movements of the
lens to interfere with the teleconverter. Plus, to lock the lens, and
remove it from the TC, you unlock it, set to 50 and then lock it. Kinda
strange, but not a big deal.
A wonderful addition to my lens arsenal!
Couldn't ask for more!! Excellent lens!! October 3, 2007

I own the Olympus 35mm Macro lens and the Leica D 14-50mm Standard Zoom lens, so I needed something with more zoom capabilities. I searched for all the telephoto lenses available for the Four Thirds Mount System, but either too expensive, or not they don't come with a high zooming range. Then I saw the Sigma 50-500mm Telephoto lens, and thought that with that price tag, this would be like a dream come true. I had to wait about 4-5 months for this lens to be available on line (but it was worth waiting for), and as soon as I found out it was on sale I ordered one.
Assembly: The lens is very sturdy and all the parts are well assembled. You won't see any loose parts. And its a perfect fit for my camera, Panasonic DMC-L1K. Afterall, it's 'Made In Japan'.
Materials: High Quality matt, yet metallic feel. High quality rubber zooming and focusing collars.
Focusing: Auto focus could take some time if you're shooting a scene with lots of objects. And when the zoom is at it's maximum, it would be quite a challenge to focus on your subject, so it's highly recommended to use a tripod. Manual focus works perfectly, although a tripod is highly recommended, not only to steady the camera, but also due the lens' own weight.
Image Quality: I've used this lense for about 1 month, so far excellent image quality (colours, sharpness, etc.)
Weight: This could be an issue for this lens, because weighing about 6 pounds, you could get tired of holding the camera for a long time, resulting in a shaky and blurry images. So tripods are recommended.
Price: Excellent price for this type of lens. Most telephoto lenses with the same range cost about $2000 and over.
Overall: Excellent lens for any photographer. A valuable asset for any photographer's gear.

This lens is fantastic. I photograph a lot of wildlife and this lens allows me to get the close up shot without getting so close that the animal is spooked by my presence.
