We naturally shot with the Pentax K-3 as it's the highest resolution offering from Pentax (as of this review's publication) to wield the K-mount. Because of the premium lenses we are dealing with, we are confident you want to see 100% crops rather than scaled down versions in order to finally settle the score about image quality comparisons between these four lenses at all relevant focal lengths.Īnd finally, a small but important detail regarding our methodology. This page will be an especially long one for no other reason than there's a lot of images combined with their size. As you would expect for the contrary, the closer to the center before the converging lines are indistinguishable, the sharper the lens and the higher a resolution it is capable of attaining. Reading the charts is easy - the earlier the image blurs, the softer the lens. But when shot in a controlled manner alongside other lenses also shot in the same way, the results will speak for themselves. When observed by themselves, they do not offer much information about a lens' ability to resolve fine detail. The below "star charts" are valuable tests because they force a lens, no matter how sharp or soft, to reach its tipping point. For example, at 18mm, the camera was set to 1,800mm, or 1.8m. Speaking of millimeters, you might be interested to know that for every focal length we shot at, the camera was placed exactly 100x the focal length away from our chart. For the comparison, of course the HD 20-40mm F2.8-4 Limited and the DA* 16-50mm F2.8 were used, and for the specific focal length, a fourth lens was added: FA 31mm F1.8 Limited. For each millimeter setting you'll find not only examinations at the center, but the extreme edge of the frame as well. In order to effectively assess the resolution capable of the lens in question, we ran it through a few of its different focal lengths from widest to longest. As such, you have arrived at our most comprehensive (and thus longest) page in this entire review. This is especially true in our pixel-peeping, megapixel-counting, measureabating world of modern photography. Many would argue that if there is just one attribute in a lens to pay overt attention to, it would be sharpness and the maximum resolution the lens in question is capable of.
