Are graduated neutral-density filters really useful?

by 14 Comments

For a few years now I have been using various different filters. I mostly use them to reduce the overall light coming into the camera or to help control reflections. It seems though I always overlooked one type of filter: the graduated neutral-density filters (ND Grad for short)

I honestly thought that graduated neutral-density filters wouldn’t work very well in the real world. While they offer a reduction of light on selective parts of your image, they do so in horizontal lines. Sure, I can use this to cut the light out in the sky, but what about buildings, trees or other landscape elements that go “across the line” like the tree in the image above?

Keeping it small, using rear filters for the Sigma 14-24 f2.8 Art DG DN

by 4 Comments

A while ago Sigma joined the L mount alliance along with Panasonic and Leica.  Although it wasn’t really till recently that we started to see the true results of this collaboration when Sigma released their new fp camera.  They also released several “designed for mirrorless” lenses like the 14-24 f2.8 Art DG DN. Those lenses are both smaller and lighter than their DSLR counterparts.

One of the new features of the 14-24f2.8 Art DG DN lens is the built-in rear filter holder. It allows you to lock in a gel filter, which you can cut using the template provided with the lens.

This is a relatively inexpensive way to reduce the amount of light coming into the camera. I used to cut ND gels to fit into my MC-11 adaptor and while they worked, the gels could easily scratch, bend and crease, while also reducing image quality a little. I don’t know, maybe it was the particular ND gel I used.

What if you wanted something that is more durable with better optical performance, but without needing a huge 150mm filter system to attach onto the front of the lens?
