K-x is so versatile
With a Pentax you are correct. I think you could possibly say with a crop sensor camera.

That bag of flour at ISO 3200 is just amazing. The sooner Pentax get that sensor in a K-7 the better imo.

k7 settings?
Am loving my new k7, but I did notice that the pictures aren't as contrasty or maybe not as sharp as what I had achieved on k2000? I know the default setting is on "bright", but is there adjustments you K7 owners make to sharpness and contrast? Or is this a preferable way, and make any adjustments...

K-7D vs K-x - any difference in image procesing?
Hi everybody, Does anybody know if K-7D has any difference in image processing compare to K-x (hardware) or the difference is due to the number of pixels only? E.g., according to DPReview tests, D300 has a sharper picture than D90 in spite of the same sensor due to higher spec image processing ha...

Noise when mirror is up
My K10D makes a noise when the mirror is up, it always has. I believe the SR actuators still activate to hold the sensor in position even when the SR system is switched off. That could explain the noise.

camera set-up
I read somewhere on the web (where, of course, everything is to be believed, but this was couched in such seriously arcane etchnical terms that it impressed) that the 6mp sensor in my K100 has its widest dynamic range at 400ASA so that's where I leave it, particularly in winter when the light's low....

camera set-up
The highlight protection on K-7 works much better than the dynamic range enhancement on K20D - I never used it with the latter as the increase in noise was dramatic even at lower ISOs. With the K-7, switching highlight protection on works well and appears to have negligible impact on noise, at leas...

Here at last: 645D
Not so sure - there are many Pentax medium format film users out there, and if they can use their existing lenses on a 645D that has what I understand to be the same sensor as a Hasselblad but at a fraction of the price, I think Pentax could sell quite a few in a market segment they may even be able...

In theory the larger sensor should allow much lower noise. However it depends on how many pixels they try to cram on to it..... If I had the spare cash I'd be buying 645 lenses by the dozen off ebay now.

Wild speculation
Some people have been suggesting that Pentax will/should follow Sony and create a full-frame DSLR. Others are suggesting that they should follow Samsung and create a 4/3-competing EVIL. Here's just a wild thought, given Pentax's tendency to do things differently with DSLRs (small 'limited' pancak...

Wild speculation
I think for the coming 5 years Pentax will keep making DSLR like they do now and only APS-C and don't forget the 645D. I simply don't think Pentax has the resources to compete with others on a different scale and Pentax should not try in my opinion. Pentax need to have it from the Pentaxian, the m...

Wild speculation
Cropped resolution wouldn't be too great though would it (based on even the current highest resolution '35mm format' sensors). True, but it would stop people who have bought expensive crop glass (I'm thinking especially of the 200mm and 300mm primes) from being tied to the APS-C bodies by them (whic...

Yes I had roughly calculated 9mp cropped based on a 21mp ish 35mm format sensor. Yes I agree, I guess 9-10mp isn't so bad at all. I've got some FA primes which would be nice :D

So if you're going to use your old lenses there is nothing to gain really. There would be something to gain if you were going to use at least one FF lens. The ability to use a mixture of FF and APS-C lenses would be good as it means you won't have to change ALL your lenses. I'm not keen to give u...
