I can directly confirm those numbers via recent experience with both of those bodies. The high-ISO advantage is certainly real. Especially past ISO 6400. I don't care about every other FF/APS-C difference
Im going the same direction.. what i really care and like about FF is the ISO performance especially for events where light is too dim.. all the other things i can match them ( most ) with something like the K3 and some postprocesing and will be great. but ISO at APS-C have a limit...

Ofcourse for shooters that dont do it during the night/events or dont shoot at larger apertures they wont notice the difference between FF/APS-C .. and is not that APS-C is not going to do the job, its just that is not going to do it THAT good..

I must admit that I too would like an APS-C that will have a processor that can shoot low light at 6400 without noise. Though FF may have other advantages, this is one of those I wish Pentax would give in there coming APS-C cameras.

True. There's a technical basis for that difference. It's not a value judgement.

Im thinking more like a high ISO performance, thats really what i ment, for example a D610 can go up to something like 2900 ISO without noticeable noise, but our K3 stays at arond 1200.. wich is not bad at all for an APS-C.. but as i said.. besides this ISO performance APS-C can do some great work... i wish to have int he future some APS-C technology that can push the ISO to something like 2000 without much trouble.. that would be nice specially for night/indoor shooters that need fast lenses
If you take a photos at 2900isos on FF and you are not limited by the lens on either side, the equivalent shoot in deph of field, speed and framing would show 1260 isos on the metering of APSC. So this important only if the APSC lens can't be more wide open or if the optical quality is lesser at this apperture on the APSC than by the equivalent FF lense.

So the high iso adventage of FF is there, that's for sure, but it only kick in on wide appertures. Shoot at f/4 on your FF and the adventage is not that big anymore already has it is fairly possible to get very good f/2.8 shoot on an APSC. The image quality might suffer a bit on zooms or some prime, through. f/5.6 and smaller apperture, there no more high iso adventage for FF on most common focal lenses as it is easy to find an affordable lens that would perform good enough at f/4 and allow to reduce the isos. This is while A7s is a really strange marketing position. It has slightly better high iso but the Sony lens offering in term of appertures make it rougly at a level on any APSC with an f/2.8 zoom and it get kicked by any Nikon/Canon FF with some f/2.8 zoom... Still many think their A7s is the low light kind

The real FF adventage here is with an f/2.8 zoom or shooting prime f/2 or f/1.4... The APSC would manage to handle a transtandard zoom with some success due to sigma 18-35 f/1.8 that is quite affordable and quite a good performancer but that would work only for this focal range (27-52mm FF equivalent). And it is likely than an FF prime shoot at f/2 look better than the equivalent APSC prime shoot at f/4. Lastly, if you use f/1.4 on FF, there no real equivalent on APSC.

Last week I went shooting by night, and stayed the virtually whole time at ISO 1600, f/2 in order to get acceptable shutter speeds (even though slower to 1/focal length...).
Photos turned out really good, but I wouldn't have minded to shoot a stop faster, or to stop down to f/2.8...
Besides, that doesn't allow me to shoot with the SMC-M 28 f/3.5 and the DA 40mm f/2.8 XS at night, because even wide open would have been too slow.
That's a real-life situation I can think of... however I really enjoyed the lightness and smallness of the K-01, so I don't think I would bring out a D4-like monster just to go a little faster...

Typically if you choosed f/2 but that f/2.8 or f/1.4 was equaly suitable for you the gain of FF would be to shoot with an f/2.8 (equiv f/2) zoom... With on APSC, you'd find you are not limited as prime are concerned.

Hope to add a fast lens in my cabinet preferably F1.2 but if no choice get the F1.4 also satisfied but not sure which can offer wide open image quality and sharpness

What use case for it ? My biggest problem with my f/1.4 tries is not really the lens sharpness but more the very thin deph of field that make most of the subject out of focus anyway...

For thoses that might want to play the game... Take a look at theses shoots and try to guess the apperture before checking it in the EXIF part...

It is not essentially Japanese.

I see the K-S1 as an in-between model until Pentax comes out with a proper video-ready, articulating rear LCD, and built-in wi-fi model friendly with mobile OS's.

It is a stopgap offering.

Has this difference been mentioned ...?

With pixel count being equal and at base 100 ISP, the FF sensor has bigger photo wells. This allows a greater dynamic range. In landscapes this can be handy.

However I don't want to lug around heavier FF gear so the k-3 wins there, which redresses the balance as the weight difference counts on long days out.

I'd prefer Ricoh to continue to add to, and improve, their lenses options, especially with light weight, quality, weatherproofed gear, which would improve their already clear advantage over their rivals in this area.

There seems to be a desire from many that Ricoh need a FF so the public will buy Pentax as it is professional kit. I'm far from convinced they need this FF option. Market their advantages, improve the lenses, demonstrate that FF actually has a measurable difference infrequently and be different. Pentax market share is limited, but it is strongly supported amongst many of its users- they should capitilize on this and not get into a war with FF, which will be to the detriment of most of us.

If pentax can release a k-3 sized full frame...that would change the market. A aps-c sized full frame with a full selection of lenses, would give a great alternative to Canikons FF titans. To fit it in a k3 sized body, pentax would have to have no-ibis, and that tradeoff might not be worth it.

A K3 sized 35mm body could be made, but I wonder if they would take the reliability issues due to ultra miniaturization that would be required without a bit of fear!
