About Sigma 77mm EX DG

Digitally Optimised (DG) Filters
EX DG filters benefit from Sigma's multi-layer lens coating, developed to counteract the highly reflective characteristic of image sensors. With older style filters, light would reflect off the image sensor, bounce off the lens and filter elements and re-enter the image sensor, creating a ghost image. The multi-layer coating dramatically reduces this effect. In addition to this, an optimum, neutral colour balance is ensured, increasing the white balance accuracy of the digital camera.

Wide Multi-Coated Circular PL
It reduces the glare and reflections from glass and water and other non-metallic surfaces. It deepens blue skies, and saturates the colors. The Sigma circular PL filter is designed to give best performance with AF Cameras. The Sigma wide multi coated circular polarizing filter is very thin, so it does not cause vignetting with wide-angle lenses. You can monitor the changes at different angles through the viewfinder as you rotate this filter.

The Sigma 77mm EX DG is commonly used for Image manipulation, Lens protection and more.The Sigma 77mm EX DG is most used by customers who consider themselves to be a Photo enthusiast, Semi-pro photographer among others.The Sigma 77mm EX DG is popular because customers like the following qualities of the Sigma 77mm EX DG: Clear optics, Consistent effect, Easily mounted, Easy to use, Firm mount and Strong construction

Excellent for Sigma 10-20/Canon 17-40L

I bought this to go with my Sigma 10-20 UWA and Canon 17-40L. It does a fabulous job on both. Its thin-ring design means no vignetting on ultra-wide angle lenses. It stays on my 10-20 (until I put my 17-40L on!).

Pass this one up

I own plenty of Sigma products but I am not happy with this item. No matter what I do, I cannot get the filter clean.. As a result it has become as a expensive, worthless filter.

Second SIGMA filter

By

from Nebraska  -  Photo Enthusiast

The polarizer did everything it is supposed to do. This is my second one and am very happy with the solid construction and ease of use. It's on my wide-angle lens full-time. No need to buy the overpriced brands when this one does well for me. Certainly will buy more Sigma stuff!

Works Great With My Canon Wide Angle

By

from Fort Collins, Co  -  Photo Enthusiast

I'm using this polarizer on a Canon 10-22mm zoom lens. I usually buy a more expensive brand, but this filter is doing a great job for me. Strong polarizer effect makes outdoor shots really come alive. It's a thin filter, so no interference even at the widest setting. Probably will buy Sigma filters again.

Not cheap, but worth it.

By

from Jonesboro, AG  -  Photo Enthusiast

I bought this specifically for use with my new Pentax mount Sigma 10 20 mm f4 - 5.6 zoom. While many caution against polarizing filters with ultra wide lenses, I've found them useful in certain situations. This filter allows me to use the Sigma petal lens hood, which another filter I have wouldn't. Results are excellent! Now, if Sigma would put a portal in the hood for easy adjustment of the filter.....

Excellent filter

By

from Hampton, NH  -  Semi-pro Photographer

I use this filter on a sigma 17 to 50 f2.8, I like the idea of using matched filters from sigma. I have had great experience with this filter, color enhancment is excellent, very easy to rotate, threds perfect on sigma lens. Especially for the price, this a a high quality optic, clear and no distortion, just bought the 82mm for my ultra wide as well.

Smears easily, can not clean

By

from Minneapolis, MN  -  Photo Enthusiast

I share the cleaning problems reported by another reviewer. I cannot clean this filter satifactorily. I've tried pens, microfiber cloth, lens paper, solutions, etc. They only move the smears around. Other than that, the filter operates well, but I wonder how much detail I'm losing due to the dirty surface.

Works like a charm

By

from Allover, USA  -  Semi-pro Photographer

The filter has a solid build and works exactly as you'd expect. Quashes glare perfectly and lets images shine through. I use it with my Canon 40D on a 17-40L and a Sigma 10-20 lens. I've included two images for a much better comparison of how striking it works, but of course the degree of effect has a lot to do with your angle to the sun. Approximately 45 - 90 degrees yields the strongest effect. The images I shot were close to sunset at the Grand Canyon. I kept the f-stop and ISO the same, and let the camera choose the shutter speed (the filter gives approximately 2 stops of light reduction, depending on usage). Just beware that the threading tends to not hold the filter on the lends as securely as some other filters I've used.

Questions about this item:

Shopper  Why Did You Choose This?
RICHARD C  needed for 10-20mm zoom used for landscapes.
First Name L  Can it be effective with tele-photo lenses as well? If not why would that be? Thanks for your help! husker415
PAUL F  I use it both on a 17 - 55 Wide Angle and a 70 - 200 Telephoto. Works well on both.
Shopper  states its for 'wide angle' lenses? But problem using with tele-photos, etc.? If so, why would that be. Thanks for your interest. husker415
MIKE E  They say for wide angle because that's where the problems happen with the thicker versions of filters. This works fine for telephoto or wide angle lenses.
