There is a website in Japan that has several photos taken with a Pentax K20D for comparison purpose. I found this on a thread listed on pentaxforum.com. The Japanese site compares the same image for auto and manual White Balance, Exposure compensation and the same image shot at ISO 100, 200, 400, 800, 1600 and 3200.
The reason I am posting the images below is that you can enlarge the images to full size by clicking on each image. Then, you can save the images on your own computer and open them again with your image processing software. I used Photoshop but use the software you normally use. From the real images now on your computer, you can compare the IQ and you can also print the images on your own printer for a comprehensive evaluation, by none other than… yourself. If your software allows viewing the EXIF, you will see that all photos were taken in JPEG with the Aperture Priority mode and a lens set at 23.13mm.

I think it’s pretty impressive. What do you think?
Thank you for reading.
