Good review, It echos my thoughts of this lens over 3 years ago (so it has to be good
), but for a few issues
One, in the "Con" section it says "Prone to purple fringing". In my real life shooting over 3 years and tens of thousands of pics I have never encountered a
PF issue. Its
there under the right conditions if you zoom in a bit (like view at 100%) but its never large enough for most users to be
offending as you would have to print huge to see it.
With the DA55-300mm you are much more likely to see the blue/green type CA at times than PF. Also saying its a con does not support their own review saying
"We did not conduct specific tests to examine aberrations as we did with sharpness. Rather, we examined a variety of everyday shots and looked for items such as chromatic aberrations and pincushion distortions. In regard to chromatic aberrations, we did specifically look for purple fringing. A common occurrence in digital photography that can best be seen at the borders between high contrast subjects and an out of focus background (for example, a blue sky). We found occasional instances of purple fringing. Nothing excessive, but in shots where one would expect to find this type of aberration, it was indeed occasionally present. That said, although this type of aberration was occasionally present, it was exceedingly minor. Another example of the fine workmanship and quality that can be found with this lens. Examine some of the images in the Image Gallery and decide for yourself." Second issue, if I am using the test pic pull down menu right it shows the lens doing 300mm at f/4. I don't think so (minor error). Or I am using the pull down menus wrong. Third issue. As I have said the DA55-300mm is sharp wide open corner to corner at 300mm. Even the review finds it sharp wide open at 300mm. This is a excellent performance usually reserved for much more expensive lens. "Surprisingly, the images at 300mm, wide open are incredibly sharp. Granted, 300mm wide open is f5.8. But the images are tack sharp, corner to corner. Examine the mortar on the edges in the f5.8 image taken at 300mm. Check out those individual sand grains! WOW!" But there copy is soft in the corners at 200mm, 100mm, 55mm (mine is not) and in the cons section the review says "Soft wide-open". Ok but at 300mm its not soft! So... IMO it should be worded different. I do agree in real life shooting this lens is sharp enough to shoot things that will be in the center like a BIF and remain sharp wide open (f/5.8). Stopped down a bit and its sharp corner to corner. I have seen a bit better from Sigmas 100-300mm f/4 and Pentax DA*300mm, but the center looks equal at normal viewing sizes between all 3 lens. The DA55-300mm does have superb Pentax color. The colors are rich and slightly cool. The lens also has excellent contrast wide open at 300mm (helps make it seem sharper than numbers would say). All of this plus being small and light, leaves little desire to upgrade to a bigger, heavy, expensive lens for an enthusiast.
