Interesting Reading about simulated AA filter of K-3
. Not that they'll be able to see the moire on the camera LCD when shooting in the first place. That's the bit that gets me. I find it hard to get a feel for the image on the rear screens, which typically make everything look ok to me out in the field :oops:

Interesting Reading about simulated AA filter of K-3
Actually not quite true. If you oversample sufficiently then you can anti-alias accurately in software. CD players have been doing this for years. If you oversample then you avoid the aliasing in the first place, i.e., it is a hardware solution, not a posteriori software solution. Your CD player...

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

Interesting Reading about simulated AA filter of K-3
It is furthermore not easy to anticipate moiré. It typically does not appear when you expect it and vice versa. Maybe that's what the new Bayer-AA-filter-less cameras are bringing to the table. They are teaching us to become moiré aware. :) After I bought the K-5IIs, I certainly became moire-aware i...

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

Upgrade the K-r
I'm in exactly the same boat Nenix. Short list seems to be the IIs and 3 for me. From what I've seen of comparison shots between II and IIs I personally prefer the slightly more detailed pics from the lack of AA Filter. It would seem you get the best of both worlds with the K-3 but I don't...

The new standard of performance - K3 shoot.
Here it is reduced to 81% And compared to the (unresized) runner up on the left I presume that owing to the greater resolution and lack of AA filter, you could also blast it with a bit more luminance NR and then sharpen it after resizing. A lot of effort to go through but you could ...

The new standard of performance - K3 shoot.
Doc, just following on from Pentaxophile's comment, if you have a sec, please could you post the K-3 one again, but after reducing the original raw file to 16 MP with no other changes? No I don't see how I could do that. The above are just unresized 800 pixels width. For me it just proves that the ...

The new standard of performance - K3 shoot.
How much dynamic range do you need? the K-5 can give upt o 14 stops worth. Call me a spoilt brat but I want it all and I want it now. What I dont need is more mega-pixal wars between manufactures. It kinda detracts from real innovation and progress. Don't get me wrong people, the new AA filter d...

Enough talk of trolls if you please.... Let's all get along and accept that some users have different priorities.

K3 has started to ship.......
There seem to be quite a few little changes incorporated on this new camera that have been requested in various forum 'wish-lists' over the last couple of years. Looking through the specs and initial writeups it does feel to me that Pentax have taken a good amount of this on board and have provided ...

K-3 studio test shots now on Imaging Resource
I have just downloaded the DNG files and edited them in photoshop, obviously there is an increase in pixels but the the ISO 3200 images looks very good to me for my personal needs. If the AF is a step up from the K5ll and the metering is more accurate together with being able to switch on and off...
