Pentax's implementation is to move the RGBG filter separate to the sensor. Not sure that's a requirement. Probably done by moving the whole sensor 1 pixel - then each physical pixel position will be exposed to each of the colours. Matt

In answer to Vics question above, the K5iis has no AA filter, therefore it is permanently 'off'. The k3 also has no physical filter but the sensor shake system provides a 'simulated' aa filter effect, and that can be switched on and off, as well as in two degrees of strength. I believe the new K...

K3 II AF...
I've asked this question in another thread but so far no answer. Does the K3ii have the same switch on, switch off filter system? You know the one I mean. The same filter that the K5ii has, but the K5iis doesn't have. I think it's called the AA filter. Does that all make sense? CHEERS Vic. Exactl...

I would think it will still be RAW, all it is doing is giving an exact/precise value for the colour by using all 3 colours off the filter layer, if they went with JPEG processing only, it kind of defeats the object of getting the higher detail info in the first place.

Pentax has not been particularly proactive in pushing these sorts of improvements down the chain. The high res mode seems an easy addition to any camera with capable hardware, which is like down to the k100d. It would be interesting to see if this eventuates as a firmware update or not. Other b...

K3 II AF...
Hi Dave Thank you - yes I had come to that conclusion. However, IF they were to implement it in the way I suggested, it could utilise a much more rapid acting mechanism as you would only need to move the RGBG filter array and not the whole sensor BUT you might have fun and games keeping it very c...

They won't separate the two and it is over the sensor just like the old 'AA' filter. I was corrected by Mattmatic (I think it was). In theory the RGBG could be separated off and above I was just hypothesising an alternative!

User feedback on K-S2
I'd have thought the AA filter simulator could be brought into play there Stan ..... Could be just the thing for wrinkles . Would have to decide on the low, medium or strong setting though :) Nice first shot for us there, looking good and sharp. Glad to hear that the handling is no problem . Look...

User feedback on K-S2
Even including the shipping is debateable. If you live in the USA, you're likely to be able to buy Pentax products cheaper than most anywhere else. At times it's different, but on the whole that seems to be the common theme. Re the K-S2, how are people finding it? Bar the higher res/no AA filt...

What 'classic' digital pentaz SLR would you recommend
My favourite is the K5-IIs, the detail it can achieve is wonderful. I have a K3, but can not get away with it. A lot of people recommend the old K10 for is colour rendition they say it's down to the CCD sensor compared to the CMOS type used in later models. I would go for the K5ii with its low light...

What 'classic' digital pentaz SLR would you recommend
My Classic choice: I have come to think of the K5 IIS as the modern day ME Super; I have number of Pentax bodies including a K3 and also a Canon FF but I just carry that K5 IIs everywhere, I just took the bold step (for me) of going on holidays to southern Italy with only the K IIs , t...

seeking advice about selling a used pentax K-r
Hi, I am new to this forum and not an expert in photography and was hoping someone here could help me. The Pentax K-r was the first decent camera I've ever had, bought it in 2012, second hand in good condition, for £250, it came with the standard Pentax 18-55mm lens. It is a great camera, but...

Ricoh AF Patent
I had a look at the picture in the original link and think I understand what is being proposed. In a traditional autofocus system, the light enters, and some passes through the primary mirror, is reflected of the secondary mirror and down into the autofocus assembly. I believe the secondary mirro...

FF sensor rumors
Rumor has it that Pentax are going to use the Sony 36 mp ff sensor for the FF body. No new technology there. Sony have been using it for 2 years now and so have Nikon. I really thought that Pentax would go with something new age. Whats are your thoughts about that? :roll: Pixel Shift That is one ...

pixel shift tests come back very positive
Thanks, good info, I was surprised on the extra size still but the results I reckon are definitely worth it, I hope this does filter down to the existing models.

I hope this does filter down to the existing models. How? Via a firmware patch? Doubt that's even possible.. Even if it was, it would be unlikely that Pentax would want to interfere with sales of the K-3II.
