Sigma 50-500mm F4-6.3 EX DG/HSM for Four Thirds

Sigma 50-500mm F4-6.3 EX DG HSM LensPMA 2006: The Sigma 50-500mm F4-6.3 EX DG/HSM lens for Four Thirds is announced at PMA today.

Sigma UK Press Release

The Sigma Corporation is pleased to announce the new 50-500mm F4-6.3 EX DG HSM for the Four Thirds fitting. This high zoom ratio lens is optimised for digital SLR cameras and capable of covering a wide range of focal lengths from 50mm standard to 500mm ultra telephoto. When used on a Four Thirds camera, the effective focal length will be 100-1000mm. This ultra-zoom lens employs a seven-group zoom system, which provides a high zoom magnification of 10x. Triple-cam Rear Focusing System ensures high precision throughout the whole focus range. The new lens coating reduces flare and ghosting, is a common problem of digital cameras, and also creates an optimum colour balance. This lens uses four pieces of SLD (the special low dispersion) glass for excellent correction of color aberration.

- Most effective coating for minimizing flare and ghost with digital SLR cameras.
- Triple-cam Rear Focusing System ensures high precision throughout the whole focus range.
- Uses four SLD (the special low dispersion) glass elements for superior optical performance.
- Accepts both 1.4X and 2X APO EX Tele-Converters, the lens can be used as a 1000mm ultra-telephoto zoom lens.

A zoom lock switch eliminates ‘zoom creep’ during transportation, a convenient addition when traveling.

The rear focus mechanism produces a non-rotating front lens element which accepts a bayonet petal shaped hood, included, which prevents extraneous light from degrading the image quality.

  1. "Bigma" returns, one of my favorite lenses! Weighing exactly half of my Son's birthweight, packing this beauty is a chore, but well worth the sweat. A big boost for the 4/3rds fans! A great lens!

  2. doesn't that mean with a 2x teleconverter you would have a 1000-2000

  3. I didn't spend 3 years in 7th Grade for nothin!..100x2=200, I think!
    200-2000 ain't bad, if you can handle the vibration, in other words, a tripod would be really necessary for the long side!
    I use my 50-500, almost, on a daily basis, a wonderful lens for the $, but it is heavy, and a bit slower than it's older brother, the 170-500, which was tested by Popular Photography as actually a 168-554, and, is actually brighter than the Bigma (In Canon mount it tested to 5.6 at the max telephoto setting)
    I use this lens too, alot now that it is getting darker as winter sets in. The drawback to the 170-500 is that it dosen't focus as close as the 50-500, and I have to put a 12mm spacer between the lens and camera to get close shots, and, then I also lose infinity because it will focus only out to about 60 ft.
    I highly recommend both of these lenses,the original 170-500 was discontinued, a used one at a bargain price would be great. There is no "creep-lock" on the 170-500, solved on the 50-500 with a manual lock to prevent that un-nerving extention when it isn't expected!
    Big filters so be prepared to add more $ if you plan on them, I use a UV/ protector on both mine, just can't bring myself to get a PL!
    One last thing, the 50-500 actually is a great all-round lens because it focuses so close, shooting stuff as close as your feet on the ground is nice, real nice, a great portrait lens, but if you plan on getting one, better start doing those push-ups now!
