The way I use this filter is by combining it with a fast lens like the sigma 18-35mm f1.8 art. I use this filter in combination with the fast apertures to blur out the backgrounds in broad daylight without letting too much light into the picture. If I want to make it lighter or darker all I have to do is turn a ring at the edge of the filter.The only thing that gets me is when I turn it too much and it ends up unscrewing the whole filter out of the threading a little bit. But that's not a bad thing, its just a part of the experience.I bought it 8 months ago. This has been, thus far, an excellent purchase.

The 1/4 was perfect for my Sigma 18-35 1.8 + bmpcc4k. It takes the digital sharpness off and adds a really nice glow on light sources. Love it!

I bought this to go along with my 24mm stm pancake, 18-135mm kit lens and my sigma 18-35mm art lens. For $125 you really can't go wrong. The stm focus is loud especially compared to the kit lens which is basically silent. I paired it up with a JJC LH-68 hood and the whole package is light and small. Not sure if I need the 24mm pancake now.

I am using this bag for my Nikon D5000 with only one 18-55mm lens. It should fit another lens, but I am not sure.

I use this with my Nikon d5500 and it fits well with a 35 to 70mm zoom attached. If you go with much bigger, the config will have to change to fit it. It will hold an additional zoom and some misc items. It's a bit much to carry if you are going to stick with a single lense all day.

Why i first went with the Sigma 35 i have no clue! Ended up getting this one after my sigma took a fall and was getting repaired. I know am selling my Sigma 35m because it can't compete with the canon version. Its worth every penny.

I really like it. Works geat with my 18-300mm Nikon lense.

I use this with s Nikon D7500 and a Sigma 600mm lens and it works perfectly.
