Pentax D FA 150-450mm f/4.5-5.6 ED DC AW

Pros: Excellent sharpness even at full aperture, ensuring uniformity to the various focal lengths, robust construction, fast autofocus.

Cons: Hood too light.

Opinion: Using this lens for about two months, and I am very positively impressed by its optical quality. In particular, the yield at full aperture at the maximum focal length is surprisingly good: looking at photos to PC with 100% magnification, it is very difficult to distinguish, on the basis of clarity, a photo taken at f5.6 and 450 mm from one taken at f8 or f11. With respect to chromatic aberrations, seem to me very little present, mildly visible only in some areas with very high contrast (thin purplish margins between next to burning lights and shadows, easily correctable in Lightroom or equivalent program) and only magnification to 100%. Autofocus in "single" mode (with K1) is very fast and very accurate, I have no experience with similar objectives of other brands, but really do not think they are many situations where you could ask for better. In "Continuous AF" greater efficiency and speed to follow the subject may be useful in action photography, but this relative limitand continuous AF (though not serious from my point of view, the lens is well-used in nature photography) I think is attributable to more than the lens camera. The lens construction inspires confidence for its strength (with the exception of the plastic lens hood, too light and that seems destined to break easily), and AF buttons on the barrel are actually useful. Well it made the hooking system / removal of the bracket to the tripod. The price is relatively high, but it seems to me entirely appropriate for a lens of this level.
