I would use this lens all the time if it wasnt so heavy. It does help keep my arms in shape though! This lens is sharp and the depth of field you get at 200mm with a wide aperture is awesome. Many of my friends are mom-ographers. I always recommend they start out with a simple 50 mm then after they get used to their camera I tell them to take the plunge and get this lens. Its great for shooting kids at their sporting events or just playing in the back yard. The quality of the images are amazing. I use this lens when shooting lifestyle outside or shooting fashion in studio.

Excellent polarizer! A must have if shooting water such as lakes, ocean, etc as the glare is almost completely cut. You will be amazed as you can shoot thru water. I took pictures in Hawaii where I can see people swimming underwater quite clearly, and the surf froth itself is well highlighted. In Japan, I shot Koi in rivers and ponds that couldn't otherwise be seen with naked eye or plain lens. I find that colors such as leaves on trees and rocky mountains are deeper as glare is removed. Phenomenal!A tip:Don't twist on your lens too tight and when using only turn in the "tighten" direction so you never have to worry about falling off!5 stars! Have fun with this!

Most people into photography will instantly recognize the name K&F Concept as makers of high quality photographic equipment and these GoPro lens filters are no different. Quality multi coated optics are used in both the CPL and ND filters.With this lens set you get three ND filters (ND stands for Neutral Density - more on this in a minute) and one circular polarize filter.The CPL filter is a circular polarize lens filter. These are used for reducing glare in your videos and photos. It also helps brings out the deep blue in skies when shooting the sky, clouds, etc.You can rotate the front of the CPL lens which is a great feature as it allows you to see what effect it's having on your color in real time as you turn it.The ND, or neutral density filters act basically as 'sunglasses' for your camera's lens and sensor. They come in 8, 16 and 32 stops reduction which gives you plenty of variety and choice.One fairly typical use of a ND filter would be for taking a photo of a waterfall. You want that classic picture of a static landscape BUT with the water showing movement and flow.In order to achieve this, you'd have to deliberately overexpose the shot in order to give the water motion however in doing this, everything else in the picture (besides the waterfall) will be blown out and overexposed to the point of almost total whiteness!Now, if you place a ND filter on the lens, you're forcing the shutter to stay open longer resulting in a perfectly exposed picture with the flowing water in the waterfall.This is a great lens kit to have in your GoPro gear bag.

I've had the Action 2 since launch and always thought it could benefit from some ND filters, not only to help get me the right shutter speed in bright light, but to protect the lens, which is not replaceable. This is a set of four ND filters which cover the basics for most of my shooting needs and they're really nicely made. Neewer are really on a roll these days with their high quality, affordable camera gear.I am going to keep the ND8 filter on my camera all the time to act as a lens protector and when I am shooting in bright light I swap over to the ND32 or ND64. It is a small hassle having to keep them all clean and make sure no dust gets between the filter and the lens. I wish Neewer would make a variable ND filter for this camera, but for now these are a great solution at an affordable (but still a little expensive price).

Best Canon Lens, I think, it all depends on what your shooting.

Excellent, clear lens. will probably be my go to lens for daily shooting.

Have had my previous ones for.10 years so was afraid to.purchase. these are better than the first

It's a nice, smooth-to-operate rotating filter and I'm pleased to leave it on my lens nearly all the time unless shooting a subject where it really isn't needed.
