Lens memory and JVC's E-Shift have made A-lenses obsolete. IMHO, no extra lens to degrade MTF, ANSI contrast and add chromatic aberrations plus geometric distortions.
That is not entirely true. There are some pros & cons on both.
First let’s talk about lens memories:
- The neat feature for all you have to do is zoom your image out far enough until the black bars fall above and below your screen's viewable surface area (aka into the black surrounds).
- Cheap way to get rid of those black bars above and below the screen.
- You lose around 30-35% of light going from 1.78 to 2.35. This might mean you will have to run on high power more often, and will go through bulbs faster, but you can buy a lot of bulbs for the price of a lens.
- The light overspill on the open frame scenes. You really do want to treat your walls with something to absorb light above and below the frame to make sure the light spill will be absorbed/hidden.
- Sometimes the memory isn't perfect. It can wind up a few pixels up or down of the target, or slightly off center.
Now, for an anamorphic-lens:
- An anamorphic lens attachment and a projector with an anamorphic picture mode you're not "wasting" any pixels on useless black bars for the lens is used to optically stretch the image in order to fill the 2:35.1 real estate and still preserved the brightness.
- For 16X9 movies, you can either have the projector displays in 1.78:1 format which will leave 2 black bars on the sides or you can just simply have the lens engaged to optically fill out the entire 2.35:1 screen (this is my current setup).
- Bulky, expensive and have potential scaling artifacts and optical distortions (my has only minor of pin cushion at the lower corners but nothing to concern about and the PQ is clear and sharp as you can see in my pics above).
