Because to me, the increase in resolution does not justify the artifacts introduced by an anamorphic lens... and SMALL BUDGET.
I don't know why you persist in debating me so much on this. .. maybe because of your financial interests with your aussiemorphic lens??? All I'm saying is that there are 2 routes to constant height: zooming and anamorphic lens. Each route has it's pros and cons and it's up to each individual to weigh them out and decide for themselves. The original poster asked what was a cheap way to do constant height and I responded by suggesting zooming and the associated benefits.
Again, I'll outline them here:
- able to use full vertical resolution
- increase in light output
- overall softer picture
- potential degrees of geometric distortion
- potential degrees of chromatic aberration
- potential focus uniformity issues
- costs money
- possibly need external scaler
- no additional picture artifacts
- no cost
- none of the PROS of using a lens
- potential screen door
- not resolving full 1080 lines
There you have it.
