Pros:The quality of the Pentax lens's optical and construction materials
Opinion:It was a tough choice with the Pentax 300f4 and the Pentax 1,4x multiplier, and I've always been a supporter of fixed focals. But now I'm happy and happy with the purchase. Great zoom, of course I will use it almost always at 450 mm for bird-mounted mounted Pentax K3 II. To be honest does not seem to me as clear as the 300f4, but still it goes close, even at 450 mm. I tried it with the 1.4x multiplier, no problem. It was the ultimate proof for the purchase, of course in some cases you need to know how to play a little with the underweight / over-exposed. Ultimately with the duplicator I have a 630 mm canvas. In the rowing hunt you also need to get used to weight, with 300f4 it was just another thing. Personally I believe that in the reviews at the end are the photos that are faithful to the opinions, so good vision.
Opinion:I bought used today this goal, the first impression known that F6.3 is already sufficiently clear even to 450, I see no chromatic aberration and it seems to me that with my ff used k-1 is optimized and not seen vignetting and .soddisfatto now I will try to optimize it better to use it to focus 450 per avifauna.oggi I rediscovered semispot function that works well 9 times out of 10 with k1, and this, in doing so I no longer need to underexpose with plenty of light, now I use only this goal and you can see my pictures to get a more precise idea, now after a month of use I am well aware that the photos are sharp at f5.6 decent as in my photo call f5.6, thanks
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.
Pros:build quality, uniform yield of 150 to 450 mm
Cons:chromatic aberrations, slow AF, TA not made in exceptional, price, resale value
Opinion:I bought this lens trying for the second time to return "home" Pentax but there's just been feeling, I sold after just a couple of months. The build quality, which has always distinguished the brand Pentax, is excellent: excellent arrangement of the rings as well as the shape and generous size of the bracket to the tripod, very convenient for transportation. It was a disappointing yield: a lens that level (and its price) I never expected to have to close at least two thirds of stop to get a good quality. The presence of abundant chromatic aberrations (purple ones, for instance) has left me stunned, remembering the old lenses. The most disappointing thing ever, especially in light of the much-vaunted improvements achieved with the K-3, was the autofocus: assolutissimamente not in line with the competition. The combination of Pentax K-3 / D FA 150-450 was flanked by me and compared simultaneously with Canon7DMarkII / 100-400 IS II: apart from the 50 mm less, we are on two different planets, coupled between the two seem to be 10 years of difference!
