Variable ND filter for video: Why use it?

Variable ND FILTER for video EXPLAINED!

We all want that buttery, creamy and blurry background when filming, right?
Did you considered using a variable ND filter for video? In fact, there is NO REASON to buy fast lenses like the Canon 50mm f1.4, if you want to shoot footage outdoors without an ND filter on it.

Video settings when shooting in daylight can lead to something tricky in most cases. At a 1.4 aperture, you’ll probably end up with the whole image overexposed on the LCD screen. A 1.4 aperture is letting a big amount of light onto your sensor. If you really want a cinematic motion blur, your shutterspeed needs to be double than your frame rate. If for example you choose 25fps, the shutter speed needs to be 1/50. For 30 fps it needs to be 1/60 and so on. You lower the ISO value to 100 and you’re done, there’s not much you can do after that. And because you’re stuck with those settings you’ll need to use ND filters on the front of your lens which will act like a pair of sunglasses for your sensor.

In the video, I was shooting with a Canon 24mm f2.8 lens on a Canon 80d. I love this lens very much, because combined with the 1.6 crop factor of the camera, Imy focal length is somewhere around 38mm, which is really nice!

Here is a cool trick

The awesome part is this: if you have multiple lenses like I have, you only need to spend money on 1 ND filter and for the rest of the lenses you can use step-up ring adapters, they are very cheap but very useful.
