Pros: Fantastic colors, accentuated microcontrast, is the only fish-eye on the market that can mount filters, dimensions, versatility.
Cons: Purple fringing really accentuated, lack of tropicalization.
Opinion: The Pentax 10-17 / 3.5-4.5 fish-eye is a fantastic goal. Now I have it for more than two years and there is no occasion where you do not take it with me.rnUnlike the "normal" fish-eye, the Pentax has a couple of interesting features: it is zoom, and can mount filters a vite.rn1) As for the zoom, unlike for example the Canon 8-15, Pentax does not pass from circular to diagonal. The zoom is a true zoom: at 10mm the lens is a complete fisheye, at 17mm it is a "cropped" fish-eye, which means that it loses some of the typical deformation to become a slightly distorted wide-angle lens.rnThis, combined with the fact that the lens is really small, manageable and autofocus, makes it a great companion wide-angle for any type of output. "Defishare" via software this lens from 14 to 17mm is really easy, and the results are very good. But even without these steps, but only by learning a little to compose, at 17mm you can fare interesting photos and without the deformation note particularly.rn2) On 10-17 you can mount screw filters 58mm, even if only the maximum focal length of 17mm, penalty vignetting or full framing of the filter.rnThe filter should be screwed into the lens hood integrated petal, which is knurled inside and holds the thread perfectly and without any risk; for a good result it is then necessary to "close" the petal of the lens hood, with a black cloth, a strip of black velcro, a wide black rubber band or whatever you want.rnrnThe use for the landscape, especially natural, is highly recommended: wider focal ones just keep the horizon at the center to prevent distortion annoying, the narrower focal simply defishare on Lightroom (which already has the integrated profile to do it). In addition, the ability to use filters greatly increases the creativity already inherent in this type of lens.rnEsing small and light, and so versatile, on special occasions canò also replace a normal wide angle rectinear.rnrnIo I use it with extreme satisfaction even during the concerts: the autofocus helps a lot, and even here the fact that it is a zoom from several creative possibilities on how to set the photo. |
