![]() | Pentax SMC FA 50mm f/1.4 Pros: blur, sharpness from f / 2 onwards, great colors, very bright Cons: materials not beautiful, flare, soft wide open, nothing quick-shift Opinion: From f / 2 onwards returns fantastic photos as well as blurred as that sharpness, that as color rendition. Under f / 2 is soft eaf/1.4 soft. With the sun in near suffer very considerable flare. The autofocus is traditional (a whisk) and that's fine, as both speed and noise as being the excursion of the ring very low. It does not have the quick-shift. sent on March 25, 2014 |
![]() | Pentax SMC DA 40mm f/2.8 XS Pros: compactness, risolvenza, aberration control, fuzzy Cons: aesthetics Opinion: It has more or less the same optical characteristics of the DA40 limited and in addition has the rounded aperture blades, which makes the blurred slightly better. And 'incredibly small, even more than the limited, but this does not have the advantage in construction. The barrel is made of plastic and the cap is made of rubber and fits in pressure, so it tends to peel off very easily. The autofocus beater is fast, accurate and quiet. Optically really nothing to say. sent on March 25, 2014 |
![]() | Pentax SMC DA 55-300mm f/4.0-5.8 ED Pros: Focal length, compactness, low weight Cons: Autofocus to whisk very noisy Opinion: It 'a tele-zoom of good quality in relation to price, very compact and lightweight, has A resolution discreet, always in relation to prezzo.rnOttimo lens for the holidays and for photos without much need to crop. E 'out the new version tropical conditions, which unfortunately keeps the autofocus beater that to me is the major limitation of this objective, because it is very noisy sent on March 25, 2014 |
![]() | Pentax SMC DA* 300mm f/4.0 ED (IF) SDM 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) sent on March 25, 2014 |
![]() | Pentax SMC DA 40mm f/2.8 Limited Pros: Very small size, risolvenza at the top, excellent build quality, speed and accuracy of autofocus Cons: f/2.8 and not more open Opinion: The DA40 f/2.8 Limited is a lens that continues the long tradition of pancake 40mm Pentax. And 'A resolution optics with high and good control of chromatic aberrations and flare. It has a fuzzy very good, even if it is "only" f/2.8, which is clearly not up to the more famous and expensive FA43 limited. The build quality is exceptional, with all metal construction makes it a real pleasure, both to touch and to the eye. The lens hood is built into the cap screw. It 'so small it fits in your pocket. The autofocus is traditional (a "beater"), but given the very small excursion is fast, quiet and precise. sent on March 25, 2014 |
![]() | Pentax SMC DA 17-70mm f/4.0 AL (IF) SDM Pros: Risolvenza high at all focal lengths and already at full aperture, f / 4 fixed, excellent build quality, SDM Cons: absence of sealing, is sometimes reported difficulties hooking dell'autofocus to 70 mm Opinion: The DA 17-70 is a great lens in my opinion, with A resolution as not to regret the fixed lenses at all focal lengths and already at full aperture. And 'f / 4 fixed and has a great zoom range from wide angle to medium telephoto. Clearly this makes it faster Zoom basis (the DA18-55 in its various versions) but impacts on blurred, which is clearly not that of a lens with aperture f/2.8 or even more open. It has an excellent control of flare and chromatic aberrations and a really high build quality. rnrnAlcuni users report difficulty hooking autofocus 70 mm, although personally, I never had the problem on my esemplare.rnrnE 'perspective that sicuamente board for ease of use and overall quality, sin only by the absence the sealing. sent on March 25, 2014 |
