The lens in the picture is very blue. Is the lens really that blue or is it clear? Maybe they photoshop it blue to make it show up better for the photo?

It does have a bluish tint to it. It's not as blue as they show in the picture. I never really noticed until you asked. I don't know what you are doing with it but it works fine for my purpose.

Frank, I think you hit the nail on the head...that is, it appears that way to enhance the fact that it's glass. The lens is actually very clear. Thanks for the question.

I have never noticed anything that I magnified looking blue just clear. The lens does look bluish from different angles but does not change the color of the object you are viewing.

I got this lens for my brother, and I really like it, we used a lot. Take a look of some pictures at www.mediawork.ws

When I purchased this I read in all the reviews the body is WR but the lens is not. I don't understand why they sell the lens with the camera when it is not WR. But it was not a issue for me personally .

I'll be honest and say I don't know. It's a beautiful lens but I would suggest that if you leave close to a large photo store go in and see if they will let you play around with one. Sorry that I can't be more helpful.

I don't understand why Yahoo is asking me about this lens. Can you tell me?

Very strange, but they have the same lens listed twice! I was wondering this too..but they're the same lens. Sorry for the late response!

It's a pretty light blue! I wondered the same thing before I ordered it. Must be something odd with that picture. By the way, I love it!

no, but an amazing lens - sharpness and color rendition is as good or better than any pro lens out there. i am a pro for 35yrs, this is a great lens.

Not on either the surface of the lens (back or front), nor anyplace inside the lens. Check to see if there is anything on the surface, although even if there was it should be out of focus. Are you seeing this through the viewfinder of your camera (or LCD display), or when you look through the lens (detached from the camera)? If you do not see it with another lens on the LCD display, then the problem is with this new lens. If you do see it with other lenses, then possibly dirt on the camera's sensor. In either case, try to exchange the product.

It is probably a kit lens they've taken out of the kit and selling it separately.

I second guessed myself as well in the beginning. The lens has a pretty long manual throw. i.e. it takes some big turns to get things into focus manually. Keep trying and it should eventually get things into focus.

Go to the Sigma website to see sample pictures. It looks like the lens has slight pincushion distortion. You may be confusing distortion with exaggerated perspective. Of course, this lens does make near objects seem very large compared to distant objects. That should not be considered distortion. You, as the photographer can use the perspective to your advantage for creative effect. If you do want distortion, apparent bending of straight lines, you should consider a fisheye lens.

Really quite Good. This is an excellent lens. I still have mine. Maybe the photos I took with it are still on http://amazon.com. Check out Kurtmunger for excellent review of this lens.

Hi DB it must have been really late to reply to your message now. I've just recently bought this lens and it is the newer version now. It can be identified with a smooth body coating instead of the old matt one. It is better now and the colours look less yellow.

Chromatic Aberration causes blurry pictures. I have been using this lens for over 4 months and I didn't take any blurry pictures. But also I have been using this only for indoor portrait photos since I bought it. So I am not sure what would be the result outside with nature pictures and more complicated backgrounds. Now I am also curious about this problem too. :-/

Fish Eye Lens Effect around BOTH sides - the only way to get rid of this is to zoom in far enough until it disappears and then leave it that way always. Also the color reproduction isnt very accurate.

Suggest you, as quickly as possible, return the lens. I waited too long and was unable to do the return. The lens adds little, if anything, to your photos. It's a big hunk of glass that does next to nothing.
