Use step up ring filter adapters to save money on ND Filters (and possibly other types of filters). Easy tip: Buy one ND filter with a large-sized diameter and use it with any of your lenses. Inexpensive step up rings can save you from buying ND Filters for all of your lenses.
Why I Needed ND Filters
I’ve been doing a lot of outdoor videography lately. And I’ve come across a problem that I hadn’t experienced with still photography regarding exposure settings. See, I like to use wide apertures to get that isolating focus on my subjects. And with still photography, I can shoot pretty wide outdoors (e.g. f/2.8) with no problem. That’s because high shutter speeds help reduce the amount of ambient light getting to the sensor during exposure. So, even though I’m allowing a lot of light in through the lens with those wide apertures, the shutter speed helps prevent overexposure.
With video, I don’t have that kind of freedom. Shooting at 24 fps, the recommended shutter speed is around 1/50 sec. And even when using a low ISO, if I want to open my aperture up, I’m definitely going to overexpose most of time. I needed to find a way to cut down on some of that light. I needed a neutral density filter.
How I Saved $100+
Since I’ve got more than one lens, each with a different filter diameter, I figured I had to purchase more than one ND filter. Then I found this tip (see video). And I couldn’t believe I hadn’t thought of it myself! Step up rings, of course!
