  • Fisheye Lenses
    could record celestial observations of an entire hemisphere The exaggerated fisheye world can be seen in the finder of the SLR camera and this lens is now commonly used for creative photography The construction of the fisheye is similar to the retrofocus type lens in which rays of light from a full 180 angle are first refracted into a cone by the concave front element and next formed into a circular image by the convex rear element Because of the 100 distortion the lens is not affected by the cosine fourth law and uniform edge to edge light distribution can be obtained There are different types of fisheye s distortion The advantage of this type is that the cubical angle of the image is easily calculated based on image size making it an excellent choice for scientific and technical applications Because of the distortion a circular picture is formed and the film format is not fully utilized Another fisheye is designed to crop a rectangle out of the circular image Because of the extraordinary angle of view the photographer has to take certain precautions when using a fisheye lens Naturally the protruding front surface must be protected with a cap

  • Why interchangable lenses
    only discern colors and shapes within an angle of 50 about 20 for absolute identification In other words the function of the retina of the eye varies depending on whether a person sees things consciously or unconsciously However since the angle of view of a lens is fixed and determined solely by the focal length what the human eye identifies in a given photographic situation is different from what the lens wi I I capture on film Practically speaking angle of view is directly related to focal length The shorter the focal length the greater the angle and the smaller the image on the film For example when the focal length is doubled the angle of view is reduced by about one half and the image size in the picture becomes larger When replaced the new lens of a certain focal length offers not only a different angle of view but also different effects of perspective and depth of field Perspective means the distorted effect in the space relationship of objects i e a distant object seems smaller than it actually is With a wide angle lens perspective is more exaggerated and is increasingly apparent as the angle of view becomes greater With telephoto lenses however perspective is almost lost as the focal length becomes larger You can see the effect of a lens on perspective as you look through the viewfinder of an SLR camera To make the most of this phenomenon remember that a wide angle lens expands the vista and makes faraway objects appear smaller If the main subject is important you must get as close to the subject as possible to maintain a proper balance in the photograph Depth of field is the area in acceptable sharpness in front of and behind the subject in focus

  • Nikon Nikkor 50mm f/2 AI Lens Review
    50mm lens Virtualy withoud edge fall off far more sharpest on f2 0 and f8 0 than 50mm f1 8AF Real kicker Jovan Ivkovic The front element is deeply recessed making the lens fairly flare resistant even with the relatively simple multi coating Widely regarded as one of Nikon s sharpest lenses I ve compared it with f1 8 and f1 4 versions and at f2 it is the sharpest of the three giving very good sharpness wide open and superb sharpness at f5 6 and beyond although on my D200 I ve found at minimum aperture f16 diffraction sometimes softens the image slightly Colour rendition is typical Nikkor with strong bright but not unnatural colours Contrast is fairly high bokeh is okay but nothing special It works well with a reversing ring to give about 1 2 maginfication I ve owned this lens since I bought my first Nikon FE many years back and it remains one of my favourite lenses on my D200 with the crop factor making it a good lens for portraits and detail shots Available cheaply secondhand if you don t need the extra speed of the other 50mm Nikkors this is a superb choice Richard D mos ri nikon nikkor 50mm Tags nikon nikkor Comments 3 Reply Better than a zoom 3 Sunday 22 July 2012 15 46 This lens occupies a distinct position between wide angles and telephoto lenses The angle of view and absence of distortion mostly seen on wides apart from 35mm mean that it is a lens you an use for 90 of your shots The 50mm lens was supplanted by mid range zooms a few years ago but photographers are beginning to take a fresh look at it Unlike zooms that are very slow f4 5 is typical the

  • Nikon Nikkor-H 85mm f/1.8 NON-AI
    rendered sharp images with just a trace of detail roundness that s currently called bokeh and a pleasing colour saturation The latest multi coated version designated H C along the lens front was the best of all Acceptably sharp even wide open it got really into its stride around f 4 and exhibited excellent image quality and contrast up to f 8 or so Due to its high speed it flared quite easily It was replaced by the much softer 85 mm f 2 in 1977 Bjorn Roslett Naturfotograph com I have used both and own the 85mm f 1 4 Both lenses are sharp have no distortion and focus accurately and quickly on my F4 They both have nine bladed diaphrams The f 1 8 is sharp even wide open The f 1 4 is just a little bit soft in the corners and there s about 1 5 stop light falloff in the corners as well Softness and falloff disappear at f1 8 But the bokeh on the 1 4 is wonderful whereas the bokeh on the 1 8s I ve tried were less than desirable On two different samples the edges of out of focus highlights were pretty sharp looking like doughnuts The bokeh on my f 1 4 remains circular doesn t start to look polygonal until f 5 6 or f6 7 and the specular highlights fall off from center to edge I didn t keep any of the f 1 8 s long enough to see if they exhibit the same behaviour with respect to the diaphram Chip Attention to Nikon DSLR owners Below Nikon D200 D50 D70 D80 D100 On Nikon DSLR bodies every non AI lens has a limitation you must set the aperture to the right position before mount the lens
