Opinion:I have this telephoto in 2013, I often use, usually freehand, accommodating stalking, it takes up little space in the backpack in the mountains and its weight is not a problem. To be a f4 yield is magnificent. The thick they match the doubler Pentax 1.4x by using it to shed to small birds with excellent results. Excellent quality / price ratio.
Pros:sharpness, bokeh, three-dimensionality, tropicalization, construction
Cons:no limiter AF.
Opinion:nothing to say, the lens excellent, optically the best 300 f4, has no weaknesses, is nothing short of sensational, leave it to f4 or close to a stop is almost identical, lens spaziale.rnla building is really embarrassing, from a sense of solidity sometimes awkward, construction is proportional to the optical quality, on another level, also because of the tropicalization AW (all weather) which makes it usable in any situazione.rnil bokeh is mellow, really ottimo.rnl'autofocus is very good, not as ipervelove certain lens L series, but really good, if it was aided by a stroke limiter af But perhaps you would not know the difference so "much" .rnrnlente spectacular.
Pros:Risolvenza wide open, construction and weather sealing, compactness, weight
Cons:lack of fire limiter
Opinion:I think this lens is the daughter of a long history of excellent 300/4 Pentax started in with the series F *, and I think this lens will be the best specimen failed. Constructively is a small masterpiece of strength and compactness, lightweight but solid, made of metal. Optically that mean? Sharpest wide open with a peak very slightly greater than 5.6 in the MTF, but not recognizable to the monitor; bokeh sweet and pleasant, never intrusive and always creamy and chromatically beautiful. The colors are saturated and returned hot, never seen anything like it. The micro-contrast is good and the lens an incisive character on the first floor. It has excellent macro capabilities, and I think with an achromatic doublet can still improve. And 'free from chromatic aberrations, and has a good resistance to flare. The autofocus is quiet and fast enough to photograph birds in flight, it would have been useful, however, a focus limiter. Optics flawless, fun and great value.
Pros:Risolvenza at the top, excellent build quality, the complete absence of aberrations, weather sealed
Cons:it is said that the autofocus is not fast
Opinion:The optical quality of this objective is indisputable, has A resolution and an overall control of all aberrations truly at the top, is weather sealed and has an impeccable build quality (it is made entirely of metal). RnDal my point of view, the ultrasonic autofocus is quite sufficient, and used with K5, it is just slower than the Canon 400/5.6 L USM Canon 7D.rnE used on 'just released the multiplier, also tropicalizzatto, which solves the limitations encountered with the autofocus with the Kenko 1.4 x (we'll see how it behaves in terms of risolvenza)
Opinion:Great tele convenient also used to "free hand." I hope that Pentax put into production by 2013 dedicated multiplier (even if they are years that Pentaxiani expect it) given the fact that the department canvases, Pentax does not offer much choice. In addition to the 300 Da, in fact, move to the new DA 560 has dimensions that in my opinion a bit 'too generous.
Opinion:How sharpness and risolvenza is fantastic. Surprisingly sharp even with the multiplier Kenko 1.5x SHQ .Dipende also from the fact that this lens is constituted by a group of only eight optical lenses. I realized even tweak some macro photos from a distance with this light combined with the multiplier mentioned above. It's really a shame that a lens has so crisp 's AF so slow and does not have the limiter, it would have been really fantastic and complete perspective. Unfortunately with the moltiplicaotre the AF becomes even more slow and unstable. Hopefully in the new multiplier estimates for 2013.rnVorrei add that the various tests that are in the network are not quite reliable because, I think that in terms of risolvenza / sharpness of the Pentax is sharper than their Nikon that I possess today.
