Pentax K 30

The talk was of a 1.3 x crop factor so it's getting nearer the 135 format. + square image format (1.3X of 35mmFF) + 22mp sensor when used in square format (23.5x23.5mm) DFX format It would be close to being an APS-H sensor as found on the Canon EOS 1D (are we allowed to mention that :?) But w...

Pentax K 30

Well let's not digress even further by discussing the digression.... The point I was making was that although the idea of a square sensor has been mooted for a long time, and the idea of a square 24x24mm film format long before that, it's a wasteful format in that nobody using squares routinely. ...

Pentax K 30

Disagree John. Using the long side dimension for a square sensor would give us everything we have now in terms of image quality in landscape mode. It would improve quality for portrait mode. It would increase the height of the camera but do away with the need for a grip. Many now say they need the g...

Pentax K 30

I don't imagine there's that much demand for a square sensor but I think it would be great. The main advantage (for me) being the ability to have a button to flip between landscape and portrait modes without having to rotate the camera. I have had a go at using a grip but it doesn't make it any less...

Pentax K 30

A square sensor would produce an image suitable for a 10 x 8 print with very little cropping needed, it would be very close to the same shot taken full frame that would have needed the sides cropping. John

Pentax K 30

A leaked quote from Pentax on the other forum suggests quite a significant AF improvement. The K-30 features the state-of-the-art SAFOX IXi+ AF sensor module, which assures responsive, high-precision autofocus operation by incorporating a diffraction lens to minimize chromatic aberration in accor...

Pentax K 30

This seems to be a fantastic camera, assuming it performs as expected. - Image quality of the K5 (lower bit-rate but some places suggesting they may be wrangling more out of the sensor) - WR - 2 control wheels! - Smaller than the K5 - 100% pentaprism viewfinder! (not many were predicting th...

Pentax K 30

What to do?, I also was thinking of getting the K5 (I have a KR) and now this pesky K30 comes out and also talk of a K5 replacement, so I think I'll hang fire for now (and see if there are any sensor issues a la K5 with the new cameras, pessimism goes a long way lol)

Will Ricoh-branded cameras disappear in 2013

Possibly, but again Possibly not. It all depends on where the value of the name is. Obviously both Ricoh and Pentax have Point and shoot compacts. Some are classed as "throwaways" such as the Caplio R series and more basic Optios. When I mean "throwaway" I mean cheap cheerful, replace in the range...

K5 - ISO 80

It depends what you mean by better, because sometimes the lower ISO levels are reached via electronic wizardry and the camera sensor may still be shooting at ISO200, the "native" level. Also, low ISO may in theory offer low noise, but that won't help if we end up with camera shake because the shu...

K5 - ISO 80

Not a measurebater I'd far rather just take piccies but even given DXO's flaws,I'll offer this as a graphical representation, my own in the field findings would tend to support this too... Look under dynamic range and you'll see it's best at ISO 80, Amongsst other stuff... http://www.dxomark.co...

It depends what you mean by better, because sometimes the lower ISO levels are reached via electronic wizardry and the camera sensor may still be shooting at ISO200, the "native" level. Not in the case of the K-5. As the DxOMark results show, the K-5 gains dynamic range at the ISO 80 setting. ...

K5 - ISO 80

There will indeed be a sensitivity where the gain is at 0. upto a certain ISO level the gain will be increased before the Signal is digitiszed and for ISOs above this level the signal gain will be increased digitally. Applying a positive gain to amplify low level light increases the noise level a...
