Official K-5 specs !!!
Yup that's why the dynamic range is firstly determined by the sensor and then by the number of bits in the digital signal path. I'd be interested to know the DR of the sensors. Isn't the DxOMark sensor test any use. Yes that's great! :) - cheers! Obviously the K-5 hasn't been done yet. ...

Official K-5 specs !!!
The K-x is really good for an APS-C camera and it only uses 12 bits. The D300s uses 14 bits, but still hasn't got the DR of the K-x. The Sony Alpha 700 has the same pixel pitch and 12 bits per pixel, but also gets beaten.

Official K-5 specs !!!
Not quite sure why you'd choose to compare it against those two - the D300s is a much higher-spec camera aimed at a different market (although effectively) replaced by the D7000, and the Alpha 700 is discontinued. Just to show that DxO DR figures don't tell you much, ...Kx "beats" D700 and 5DII...

K-5 Press Release
Looks like it has most of the answers, but as far as I am concerned, it's the auto focus and sensor quality improvements that are key. Now - who is going to be the first to buy one - test it - then let us all know if it's worth the £££ :twisted:

K-5 Press Release
heard there is some talk of using sensor to "Tune" the sensor position to specific lenses???? does that mean the sensor now shifts forwards and backwards to get rid of front/back focus?

turn off DFS with your K20D and K7
After a bit of to'ing and fro'ing about whether this was a fault or not I've just received a disappointing reply from pentax support Dear Sir, Thank you for your enquiry. We just got an answer from our software-engineers regarding switching off the NR on the K7: For technical reasons and...

The most likely thing is in the phrase "sensor management reasons" which possibly means heat. I doubt that it's a Diabolocal Plot!

turn off DFS with your K20D and K7
Thanks John Yes, could very well explain what they mean So is heat buildup (I presume this introduces noise) a known issue on long exposures for other makes of DSLR or is it only these pentax sensors that exhibit poor performance in this particular aspect? The Samsung sensor in the K20D/K7 is no...

The most likely thing is in the phrase "sensor management reasons" which possibly means heat. I doubt that it's a Diabolocal Plot! That's a bit strange if you ask me... Because it builds up heat with 30 second exposure it would be a great idea to do the same exposure of a 30 second afterwards for t...

So if you turn a sensor on for 30 seconds it gets warmer than you turn it on for 1 minute, can you tell me how that works?

turn off DFS with your K20D and K7
Perhaps so, but it will be able to map the noise and banding on a blank shot and then eliminate it from the original shot... if I'm correct in my understanding of how DFS works? OK the sensor will stay warm, there's no way round that, but it's probably got as warm as it's gonna get during the origin...

K-7vs K-5
Where did you read the K-7 is placed above the K-5? I got this in my mail box today saying that the K-5 replace the K-7. The compact new K-5 digital SLR is loaded with features for the passionate photographer. With a 7 FPS frame rate and enhanced focus performance, it's even faster than its pred...

K5, was it worth the wait?
Do I detect doubts creeping in about the K5 here and on all the associated threads on the subject:?: I decided to skip the K7 - happyish with the K20. For me if the K5 focussing and sensor is better then I will go K5 then skip K3 until K1. But are we all suffering from 'expectation drop'. We h...

K5, was it worth the wait?
The vast majority of complaints for the K-7 were ISO and focus speed. General consensus was put a K-x sensor in the K-7 and it will be 'perfect' Now we have higher ISO performance than even the K-x, faster autofocus, more frames per second, 14bit RAW for higher IQ , 1080P video and other upgra...

K5, was it worth the wait?
...the highest ISO setting of any APS-C DSLR ever... I hate top be picky but I think it's slightly behind a couple of the new Canons (and I believe they use a very slightly smaller sensor). Having owned (in sequence) the K10d, K20d and K7 there was no doubt they were getting significantly better ...
