An interesting thought regarding the K5 Vs K3 Conundrum.
How about a K-02 with a 24mp sensor....

How about a K-02 with a 24mp sensor.... That too! :D

An interesting thought regarding the K5 Vs K3 Conundrum.
That seems a slightly confused argument TBH (the article that is, not JR's comment.) He talks of wanting a simpler camera implying the K-3 is too much and then wishes a K-3 with a 16mp sensor. I can't that see that a K-3 variant with a 16mp sensor would cost significantly less to produce or be any s...

An interesting thought regarding the K5 Vs K3 Conundrum.
The K5 already has 6mp too many for my day job. I believe most pros think 12mp is more than enough. Nikon got it spot on sticking with the 16mp in the DF, but in a way that camera is immune from the megapixel race due to its 'back to basics' ethos and high end niche market. If Pentax were to bring o...

An interesting thought regarding the K5 Vs K3 Conundrum.
I have used and owned more than one make of DSLR (full and crop sensor) ranging from 6mp Pentax K100D right up to just under 22mp FF. Regardless of any brand bias I can honestly say the cleanest and nicest images at base ISO came from a 12mp FF Canon 5D I also think that 24mp is pushing it on ...

An interesting thought regarding the K5 Vs K3 Conundrum.
Personally I'd like to see the K5 line continue and I feel there is a place for it, some bits like say the burst rate could be improved by knocking the frame rate down to say 6Fps. It could keep it's build quality and basic features but the new meter would upgrade the flash and the new sensor shake ...

An interesting thought regarding the K5 Vs K3 Conundrum.
With regard to the high ISO noise comments, and not knowing a thing about sensors and how they work, would it be possible to treat two photosites as one above a certain ISO? So, above a user selectable setting, one would have a 12mp sensor but with better high ISO performance? Brian

An interesting thought regarding the K5 Vs K3 Conundrum.
If 24 megapixels is too much, how about selecting a lower setting on your K-3............... ..........and then start to wonder why you bought it! Bit like having a performance car and never exceeding 40mph. That wouldn't actually make the raw files any smaller, just the jpegs. But here's...

I think we've been here before: https://www.pentaxuser.com/forum/topic/24-3-mp-exmor-cmos-sensor-29586 Personally I can't see a lot of point going beyond 16 MP on APS-c and 36-37 MP on FF. The following may also be of interest: http://www.photozone.de/dslr_reviews/478_canon_eos_7d?start=2 ...

No doubt. But let's get a full frame camera first or talk of that is irrelevant to us, we'll be left way behind. Or will Pentax try and squeeze 54 megapixels out of an APS-C sensor? :) John K

An interesting thought regarding the K5 Vs K3 Conundrum.
Thats why I said "perhaps" John. The tech is 1-2 years away according to the link but who knows what will be around then? Not having a dig by the way...:) To double the resolution in the K3 sensor you'd need 96,000,000 little pixies, thats a lot of pixies and that may only be two or three years ...

An interesting thought regarding the K5 Vs K3 Conundrum.
Just give me a 10MP sensor with negligable noise at ISO 1024,000,000,000,000 :) If you remember to take the lens cap off then you don't need ultra high ISO :) I'm still waiting for someone to write demosaicing software which would properly downsample the 24+MP RAW files to average out noise right...

O-GPS1 Astrotracer function is phenomenal!
So how does it "follow" the stars? You attach the GPS thingy and then what? ... then it moves the sensor for you in B mode, based on the mm of the lens data, at the same speed stars move on the sensor, so the stars stay put. Like an inbuilt , which is the thingamygummy that follows the stars when y...

Ah, I'm enlightened. Cheers Nass 8)8) Surely it couldn't do it for 2-3 minutes though, could it? Presumably this would depend on where you are aiming, as some stars 'move' more than others as you head away from the poles. I just read somewhere that the max travel distance changes between Pentax m...

Advice on K5 II purchase
whether there have been any leaks of a K5 III or something, or a cheaper replacement. There won't be a K-5 III. The next high-end Pentax will be either: - A K-3 II with either a better sensor, or (unlikely) something clever in the electrickery to reduce the high-ISO noise. - Or a camera wit...
