Am hoping this is not too daft a question, but it has me puzzled.
I read useful posts by TimStannard and MidnightBlue about HD filters.
It has affected my expectations of what video cameras do. And I am now confused.
I remember SLR cameras in the 1980s with 'automatic' and 'manual' modes for iris control and shutter speed. In addition, it was sometimes possible to confuse the automatic mode by changing the ASA (film speed).
I had assumed that modern cams would offer even better automated systems.
For example, to select whether to automate the iris or the shutter speed; and also to have adjust the final sensitivity (similar to changing the ASA of film).
But, the need for an HD filter to force an iris more open (or to have to select a shutter speed manually) suggests that the automation in our cams is less than I expected.
I have looked at some manuals, but can't get a clear idea of state of the market. Whilst I am sure all those features exist in the most expensive cams, are they provided in the cheap (sub 1,000 UKP) range?
