Are all the dvx 100's like this?
A bright sunny day,no nd filter used and you point the camera at your subject, and I am faced with a pure white lcd and viewfinder.
So I switch to auto iris and auto focus in the scene file one position.Shutter off,[1/50].I still have an overexposed shot allbeit reduced from above.the camera now prompts me to use the nd filter to which I respond to 1/8,the camera prompts me to go further to 1/64.The result is finally a good clear picture as first
required but is this nd filtering common in this camera or do I have a fault?
Other than this I am totally pleased with this recent purchase,
the dvx has so many good attributes for this price camera.

Not only are all DVX100's like this, but PD150s, V2Ks, XL1s, GL2s....

All the higher end cameras have (and need) ND filters in bright conditions.

As Sean notes, neutral density are fundamental, and very desirable, elements of semi-professional and professional (full-sized) video cameras.

Dual built-in ND filters are part of what you paid for with that DVX. As you get more experienced with shooting I'm sure you'll learn to appreciate them.
