Great filter, works fine with Sigma 10-20mm f/3.5 EX DC HSM ELD SLD Aspherical Super Wide Angle lens. i had the best results.

I was going to get a Polaroid version but the price for postage was almost as much as the filter. So happy I stumbled upon this one! It's worth mentioning that this filter is perfect for a wide-angle lens (It works great with my Panasonic Lumix 12-35mm F2.8), since the outer diameter is much larger than the inner diameter (on the 58mm filter I bought anyway) and that minimises vignetting. I can't get the exact outer measurement but it's somewhere in the 65mm range and I wouldn't recommend stacking an extra filter on the end of this anyway. If you need even more ND reduction, put a filter before it instead. The Color cast is minimal, and can easily be tuned on post if you shoot in RAW, or even calibrated with the camera's "white balance" before shooting. Even though I can see *very slight* ripples in the glass when light reflects off it, I see zero distortion on the captured image. Build quality is great, feels sturdy and is well machined.

My specialized road bike has 1 1/4 inch diameter handlebars and this fit perfectly...it holds my iPhone 7 solidly in place. The neon green holder even matches my neon green paint in my bike!

We just returned from Yellowstone. The polarized lens made a huge improvement over the no filter shots. I compared a couple pictures with and without and the without shots were all washed out. My wife made some simple edits before photo sharing and she said the time was cut way down in part due to the new camera and in part due to the polarized lense. I would absolutely repurchase.If anyone is wondering about the sizes, they relate to the diameter of the lens not the thinkness of the filter (I'm new to photography). The lens on your camera will have the lense diameter printed on it

Great telescope for my 9 year old. The 20mm lens works best for him. We can see stars really clear. The moon looks amazing with this telescope. Great for beginners.

For those looking for a front objective lens cover (which Leica should have provided!!!), the Leupold 20mm cover doesn't work. However, the Butler Creek 02 Eye Flip Open Scope Cover works excellently (1.225"). Try a couple different size rubberbands over the objective lens barrel to give it a snug fit and it won't budge, is watertight, and the rubberband can't be seen. Also it doesn't interfere with the focusing ring.

I took these shots with and without filter, difference is very huge. The more green one is with filter and other is without

New to 50mm lens game. I have been using a sigma 10-20mm since I started shooting photos around 3 months ago. I haven't personally compared any other 50mm lenses to this canon stm1.8.....although I can tell you this lens takes crisp clean photos While allowing you to throw whatever style your trying to achieve look great.I'm Having a blast with the lens. Shout out to canon for making afordable quality.
