Officially K-3?
It's not often that we label an imaging technology "revolutionary", but if ever one deserved to be called such, this is it. It's a fundamentally different approach to anti-aliasing, and one that appears to have surprisingly few downsides associated with it. For the first time ever, there's a camera ...

Interesting Reading about simulated AA filter of K-3
Here is an interesting article about clever simulated AA filter developed by Pentax, and it is said "Pentax revolutionizes low-pass filtering" in it! Wow!

I totally agree that its a clever thing, and I fully understand what its doing, but why anyone would want their sensor moving during a shot just baffles Me!

one reason and one reason only, to minimise moire when shooting a subject which is likely to cause it. Whats so hard to understand?

Interesting Reading about simulated AA filter of K-3
The AA is done at 500Hz evidently, and SR happens at subsonic few Hz frequencies, so yes they can work together as they don't overlap and even if they did it would probably cope. I'd like to know if it works at all during a flash exposure which is often faster than half a cycle of 500Hz.

Interesting Reading about simulated AA filter of K-3
What will be really interesting to find out is whether having it 'on' will add to blur, in the manner of an actual aa filter. And of course whether that translates into any practical 'resolution' loss and significance for various outputs. This will of course determine which will be the preferred...

What will be really interesting to find out is whether having it 'on' will add to blur, in the manner of an actual aa filter. If the sensor is moving it will add to blur. It might be slight but it will be there; if it didn't do this it wouldn't prevent moire. Regards David

Is it possible to be so sure when this is such new technology? The blurring is after all not the intention of the aa filter - it is the consequence and secondary effect, the 'price to pay'. What I was wondering here was whether that price will be the same, or maybe higher or lower with this new meth...

Interesting Reading about simulated AA filter of K-3
Anyway, the title of this thread should be changed - I have checked the Pentax Uk site specs for the K3. It details an 'anti-aliasing' simulator. Not an 'anti-aliasing filter simulator' There is of course a difference. Simulating the effect of a 'filter' (as used on the earlier models, would impl...

I had written a long post in support of Smeggy, and I still think he's almost certainly right. I have just thought of another way you might be able to do this, but I really don't think it would be worth the extra processing and jiggery pokery which would be required. By far the most sensible and lik...

I also saw on the official UK site that there is some sort of level control for it as well - so not just 'on or off' apparently :) The trick will be to get a feel for the right amount given any specific subject.
