There has been a lot of talk on the interwebs recently about the new Nikon D800 and the fact that it has been split into two product lines, the D800 and the D800e. For those of you who don’t know, Nikon’s new DSLR is a 36 megapixel blockbuster and for the ‘e’ options, you get to pay an extra £300 and have the anti-alias filter disabled. The fact that you have to pay to have something removed is not the subject of the article, merely a sad reflection of consumer pricing policy somewhat like the extra money you can pay to have the model number removed from your high-end BMW (“if you need the number to recognise the car”, so the logic goes “then you aren’t the person I’m trying to impress”).

Anyway, this article discusses what exactly an anti-alias filter is, why we’ve needed one for so long and why we now want it removed so much that we’re willing to pay enough for a high-end compact to have it.
