AF28 ~ 105/3.5 ~ 4.5 Nikkor lens (top)

To a purpose of compromising the basic quality of the lens test lens distortion comes to many articles that observed by the camera's viewfinder lens distortion, this method can only be observed probably because the camera image through the viewfinder light path will produce a new distortion, it is best to test by real shot. Vignetting problem is actually that the problem of uneven illumination image fields, zoom lens. Especially in the wide-angle end of the phenomenon will be more or less hidden corners,[link widoczny dla zalogowanych], this lens is no exception, F3.5 F48 are present to some extent a hidden corners, shrink the aperture to F56 disappeared when the hidden corners, far side of the case focus F45 light when a little hidden corners, shrink the aperture to F56 when the disappeared. 2. Against stray light, backlit shooting performance Nikkor lens shooting performance in this area is very good, see {Figure 4), the sun is behind the sculpture,[link widoczny dla zalogowanych], the sculpture reflects the good subject contrast and levels. 11 am to sunny glare screen look directly into the camera's performance had only {Figure 5, although the picture is a few spots, but the picture quality as the outside light point of almost no interference, no halo phenomenon, the picture maintained a good contrast and sharpness. During the discussion we often say that the quality of the lens in sunny conditions made shooting the lens effect, cloudy conditions, shooting low contrast, made caused by the weak when the Yin Tianguang line between the lens reflector,[link widoczny dla zalogowanych], tube wall significantly interfere with stray light reflected from the lens image quality. and sunny days the light is good light lens intake of these stray light interference and the post-subduction Cheng Yu-quality feel, of course, with the power and resolution for clear lens sharpness also has a lot to make a circle square than to a piece of paper draw thin black line on the crowded,[link widoczny dla zalogowanych], near the time {equivalent resolution for watching high power) still black and white, a distance (the equivalent resolution for low power) and black and white line gray hair will be a confusion, Nikon lens, high resolution power, brilliant sharpness and excellent coating quality, excellent lens technology to ensure simple extinction lens in poor light conditions, good expression, this advantage is probably Nikon's many independent lens factory incomparable. 3 autofocus and manual focus only with the performance of the zoom lens automatic focus technology Coke ship travel is very short, in the normal shooting mode, focus ring alum 05m ~ �� only increases the angle of rotation around.. automatic anti-coke performance very good, but also and accurate, the performance of manual focus a lot more backward, adjusting AF lenses focus more professional feel worse, which is not very concerned about the author down, the key is focus ring trip is too short, the actual adjustment that is too often a tune, you need to look for a few times back and forth. Fortunately, I believe that in the normal shooting mode not required under the basic manual focus, unless you are using a manual focus camera. 4 Lens Nikkor lens imaging quality of the high contrast, high sharpness and high resolution power is well known, this 28 - 105ram Zoom-Nikkor lens adhering to these features the same {Figure 7-9). 28mm sharp end, 105tt ~ far as the coke-side the main body of such a richly detailed interpretation of head, in general, the quality of the zoom lens as the most far Jiaoduan Cheng weak, Figure 8 details the performance of not only quite good,[link widoczny dla zalogowanych], the texture of gold light bar also performed very real. weak indoor light and cloudy field test of the zoom lens is a good way. Figure 9 for indoor available light handheld shooting. screen clarity and contrast are terrific: Of course amateur zoom lens with fixed focus lens and professional level there are still gaps in comparison. is mainly reflected in the iris image quality and low light too, a scene of the performance of contrast Jue force, while the income of small aperture and light conditions are good the image quality when the gap between them very small, at least within the ~ fixed medium format is difficult to distinguish with the naked eye, especially Nikkor lens, and that / Si how to avoid weaknesses, selected to maximize the best image quality only does the lens, the author under the lens of the SQV abroad only to make the following summary of evaluation data for reference (to be continued 1 ��Ming Yi branch bream 5 �� 8 �� 1olIl �� l4116x2035568oA + + lA + AiloA + + {A +16 o.1 + AIBA + l + AlB15x718xl0IIx14lx2O2Ox2435 + AB + C + IC56 + AB + Jc ten 8O + + I10 +160 A + A +220 A + + AB + lB to s.
