CCD vs CMOS

Hi folks

I have a Kr currently which I love- I uploaded to Flickr some K100D shots today and took in air when I witnessed what I considered to be shots with more bite and a certain something.

Am I Mad.

Your input is most welcome!

I know what you mean, I just think it's the fact that the images are smaller and have a bit more sharpening.

I honestly think it's not that simple. But thank you

In my experience (not scientific, purely subjective), when I've shot CCD sensor cameras in good light with good lenses, I've felt they can outperform similar spec CMOS sensors.

Get into anything other than perfect light however, and CMOS tends to win hands down.

"...more bite and a certain something" describes exactly how I used to feel about shots from my K-m vs. shots from the K20d I replaced it with (in good light).

A lot of people seem to comment on the difference. It would be interesting to see two identical shots taken with sensors of both types for analysis.

This comes up quite often, I have always said that pictures taken with my K10D seem to have a much better look to them when compared to Pentax cameras since (K20D, K-7, K-5, K-5II). The CCD sensor (to me) gives what I call a glossy look to low ISO pictures while the CMOS gives more of a matt look.

Over ISO 800 (and that's really pushing it) I will take the CMOS sensor every time though
No equipment list here but thanks for taking an interest. My Flickr

Thanks Mike, that describes my experience. I love the Kr but I feel that it doesn't have the same 'oomph' at lower ISOs.

I assume you're looking at JPEGs from the cameras, is that right? Either camera generated embedded jpegs on the LCD screen or camera created & edited JPEGs on a computer screen?

Well, its difficult to be sure you're making a fair comparison unless you're sure you have equalized and eliminated any processing differences, at any stage of the process.

Pentaxophile's point above may not be the full story, but its very likely to be a significant factor.

In my testing of shots from the K5ii / s models it was clear from an early stage that there were different default sharpening algorithms applied to the embedded previews - so it seems likely that there would be considerably wider discrepancies between your two models with years of development and different technologies between them.

THank you! Even more unfair as I am comparing RAW conversions from the Kr to JPEG from the K100d Super. Even JPEG to JPEG comparison favours (in my eyes, and it is surely a matter of taste) the older model.

Can we see some examples/comparisons?
Best regards, John

Yes, please check my Flickr Link- the last three uploads.

Do you have the same shots taken with both? Then link to your flickr from here to show the differences. Your flickr pages don't make it obvious what one's seeing as a comparison.

A powerful set of images indeed. However, putting some on here with descriptions would be very helpful.
Best regards, John
