Tokina AT-X 28-70/2.8 PRO SV Lens

X28-7O lens of the first generation of products, production years earlier,[link widoczny dla zalogowanych], the image still does not germanium, but its maximum aperture of F2.8 at the time of performance is really to be commended. Too bad the entire photo imaging flexibility, the focus is not clear, 5-inch d ~ FJL say T ~-Z-,[link widoczny dla zalogowanych], but the narrow aperture of a block, that is, when F4 is greatly improved as quality Viagra, like change of like a lens. So I think the F2.8 aperture lens only exist in name,[link widoczny dla zalogowanych], almost no practical value. The 4th Generation Li-X28 ~ 70/2.8PROSV figure in the imaging lens has improved than before, especially in large aperture imaging quality compared with the first generation of products has been greatly enhanced to better narrow aperture imaging: F4 aperture increases when the overall contrast and clarity, in the F5.6 ~ F16 aperture stop these extremely high resolution, bright color saturation, sharpness are very good level and clear, Tokina AT-X lenses excellent resolution for force filling completely. It is worth mentioning that, photography circles have been circulating Tokina Lens Viagra as yellow saying, especially in the early Tokina lens. I spent a few older Tokina Nikkor lens with my standard lens to shoot a scene for the same comparison and found true. But this new version -X28-70/2.8PROSV lens color reproduction is very good, do not see the color cast. In addition, this 28mm lens has a slight barrel distortion when, with the focal length of the extension can discern a slight pincushion distortion, but are within the range allowed, usually can be ignored. In short, this is very satisfied with the imaging lens, coupled with all-metal body to create the mirror can indeed be regarded as a strong and durable, excellent image quality of professional lenses, the lens is equivalent to the original mid-range prices, there is an unparalleled advantage in the original mid-range lens,[link widoczny dla zalogowanych], it is inexpensive. Ke Wang (Shandong) relative to the price, I think the lack of this lens is its only just done recently taken away from O. 7m, is not conducive to close-up. Recently the first 3 generation of the lens are also taken from O. 7m, 4th generation of the lens in this regrettable lack of progress. Perhaps the Tokina lens in order to maintain its ATX28-80/2.8PRO gap makes the grade still have not recently taken from the can shorten it, to know the lens has already pushed ~ AF28-70/2.8EX have done O. 4m, in this regard Tokina and Sigma was not. After a period of use, I shot in all aspects of this performance is satisfactory. Tokina AT-X28 ~ 70/2.8PROSV new generation of lenses with excellent performance,[link widoczny dla zalogowanych], the lens is equivalent to the original price of similar low-cost three-Yong quarter, so I can not afford the impact of the original Friends of specialized lenses are able to live a professional addiction.
