Interesting Reading about simulated AA filter of K-3
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
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...

Interesting Reading about simulated AA filter of K-3
It is actually a brilliant little bit of design, wonderful lateral thinking. Competitors are probably kicking themselves for not doing it first and of course those with no sensor shake technology can't do it in-lens so easily. There are three settings I think, off and two strengths of moire reduc...

Interesting Reading about simulated AA filter of K-3
There is a difference between splitting the light into four beams which then fall onto adjacent sensor sites and jiggling the sensor - the result is similar but not the same. Yes, exactly, that was what I have been trying to say but couldn't put it quite that way! :) The aa filter is one 'method' of...

Interesting Reading about simulated AA filter of K-3
If we are moving to cameras without aa filters generally then you'd expect software progrmmers to start to write in some special removal tools, if its possible, along the lines of Noise Reduction. I'm not aware of any myself yet - but then again, maybe you can do it all with one click in Lightroo...

I've only had really bad moire once (ironically on the K10D :wink:) and it was hard to imagine cleaning it up easily in software without destroying the image. It was on some steel grating/mesh, and the image was basically covered in coloured stripes. Something about the spacing of the mesh just ...

Interesting Reading about simulated AA filter of K-3
So the contention that 'its a bit tricky' to deal well in software holds does it? It is impossible to accurately deal with it in software. You can mask/replace colour artifacts and/or moiré but you cannot systematically "undo" these artefacts. The term "aliasing" refers to the fact that spat...

Also, its effect varies across the image with shutter speeds higher than the sync-speed, i.e., it is not a uniform blur that is applied. It will be interesting to see how well it suppresses artefacts and responds to sharpening near its limits. In what way does its effect vary across the image? The p...

In what way does its effect vary across the image? Please see a . In a nutshell: The periodic sensor-based blurring movement is of course not instantaneous but takes time; it operates at 500 Hz. Hence, towards faster shutter speeds, a given region on the sensor will not be exposed to the full ...

In a nutshell: The periodic sensor-based blurring movement is of course not instantaneous but takes time; it operates at 500 Hz. Hence, towards faster shutter speeds, a given region on the sensor will not be exposed to the full blur movement anymore but only to some fraction of it. Which phase of th...

is the K-3 three times better than the K-5 (mk1)
Whilst I don't have a K3 (Obviously) other camera's using the Sony 24mp sensor certainly don't in my experience have a better performance at high ISO's than the K5, in fact noticeably worse:wink: Therefore, my guess is that the K3 may also not be better at high ISO's than the K5, however, as the ...

just a point about the sensor from info on another site it is from Toshiba not Sony, although what difference this makes i do not know.
