Exposure query

[Philip Freedman]

I am new to video and have been reading up on the internet. Having read that a shutter speed of 1/50 or 1/60 is desirable for 24p or 25p

shooting, I have realised that on a sunny day even the lowest ISO on my Nex 5n, being 100, will require an aperture of about f22 which is

smaller than some of my lenses can be set. Also, such a small aperture will create too much depth of field for some shots.Does that mean I need an ND filter to video in bright sunlight at a shutter speed that gives realistic results or is there another solution? Thanks Philip

<p>Hi Philip, yes ND filters is the way to reduce incoming light. </p>

<p>My camcorder has built-in switchable ND1 and ND2 filters which covers just about all common situations. </p>

<p>Even if your lenses could go to F22 you still need ND. This is because their performance falls off at very small apertures due to diffraction effects. Depending on the camera model, you are likely to want to use f11 as an absolute minimum.</p>
