As you know, the reason most digital camera sensors, save for high resolution backs, usually have so-called AA filters is to prevent the phenomenon known as moiré: that pesky low-frequency ghost image that appears superimposed on images of fine, typically man-made, materials.
The imminent introduction of the AA-free not-that-high-res K5IIs got me thinking: will photographers have to learn to deliberately introduce diffraction when confronted with moire-inducing situations? Or will a market for optional AA filters spring up to cater for the K-5IIs owner that wants to do shoot fashion or a wedding?
Then I had an
idea.
You know, the sort of idea you think is simple and clever, but are not sure if makes sense to anyone else. So here it goes.
Pentax*: add an option, let's call it "
meier moiré suppression", to your AAless cameras, which uses sensor shift to introduce artificial, deliberate 1px motion blur in all directions. Voilá! Instant low pass filter.
What do you think?
* If you read this, I'll gladly give up the rights to this idea for the low-low price of 1 of each camera that uses the technology.
Oh, and a DA*50-135, please.
