I have noticed that in Photographyblog.com and other sites, way too many sample photos are taken at way too small apertures...9, 11, 13, 14.
It is well known that for small sensors packing 12 mega pixels, anything above 5.6 or so will degrade the resulting image quality of the photo due to diffraction limitations.
For example in the review of the Fujifilm F200EXR done on this site (http://www.photographyblog.com/reviews/fujifilm_finepix_f200exr_review/sample_images/) one notices that photos were taken at, 1/200 sec f/9 and ISO 200...or 1/105 sec, f/12 and ISO 400... and even 1/200 sec, f/14 and ISO 100.
Why is it necessary to shoot these shots at these wildly small apertures?
A reviewer can photograph the above 1/200 sec, f/14 and ISO 100 photo at around 1/1000, f5.6, and ISO 100, giving us a better photo to judge the potential of the camera. The depth of field would not be an issue with such small sensors.

It is apparent that we are not given what we need from these sample photos posted in the reviews.
