Written Research on Lenses and Camera Formats

Fish Eye Lens 


Thefish eye lense is designed for digital SLR cameras, it is an ultra wide angle lens and the effect is that it is a strong visual distortion or hemispherical image. A positive effect of using a fish eye lens is your ability to get more into the image due to the distortion, moreover the wider the lens the more distortion you will have. However using a fisheye lens wont make you image unrecognisable but rather slightly unrealistic possibly, depending on the width of the lens the extremeness of this image can develop. There is two types of fish eye lenses; circular and full frame. Using a circular lens provides increased distortion, up to 180 degrees of it, and a full frame lens allows a subtler distortion.


Macro Lens

Using a macro lens provides a shallow depth of field, meaning that less of the image is in focus and the objects closest are. Macro lenses provide a small aperture, aperture allows the light to be let through, and makes the background out of focus. Macro lenses can be used by photographers to let produce effective close up shots, of flowers, bugs and portraiture usually of very small subjects, in which the size of the subject in the photograph is greater than life size  The mgnification factor of 1.0x or a ratio 1:! is easily added to the DSLR. Another interesting fact is that due to the advances in sensor technology, today’s small-sensor digital cameras can rival the macro capabilities of DSLR with a real or true macro lens, despite having a lower reproduction ratio, making macro photography more widely accessible at an increasingly lower cost. 


Zoom Lens

A zoom lens is a very common types of lens, as it enables the photographer to zoom into a subject which is an extremely handy and useful tool. Usually the standard zoom lense is188-55mm lens. A zoom lens gives you better angles and enables the photgrapher to increase the excitement of an image throught his/her ability to expose a much more intersting perspective upon the subject. A different zoom lens is a parfocal lens, this lens maintains focus when focal lens is adjusted. This variation of a zoom lens allows magnification, the image will be more magnified when focal point is father away
from the senser inside the digital SLR camera. Using a compact or point and shoot doesnt zoom as a lense would but enlarges the image, which can lose quality and become more pixellated, losing its appeal as a sharp image.


Prime Lens

A prime lens has only one focal length, however they are available in a wide range of focal lengths
telephotos and wide angles are included. Prime Lenses are typically used for portraiture since they have a maximum aperture of F/1.4 compared with the standard F/4. This lens enables the  photographer to blur the background more, since the camera has a shallower depth of field and thus the background is out of focus.  Some of the advantages of using Prime lenses over Zoom lenses include; the ability to take higher quality images, as well as be much smaller and therefore lighter than a Zoom Lens which makes transportation of said lenses easier and therefore a plus.



Telephoto Lens

Telephoto lenses are usually used in photography and cinematographic instances. The lens has a extremely long focal lens typically with the focal lens of 100mm being the smallest in order for the lens to be classed as a telephoto lens. The most common standard lens is 50mm which is exactly how you see things from your own eyes
there is no magnification.
For example, a 200mm lens would be four times the magnification of the standard 50mm so you would see the image 4 times as close up. With the telephoto lens you are able to take a good clear photograph of the moon, for this a telepohto lens of 200mm would be needed as well as a tripod clear sky and time to be able to capture with the correct photo.  You are more capable of a shallow depth of field if the subject is able to stand out from the background with the subject in focus and the background completely out of focus. Finally telephoto lenses are particularly good at capturing action and motion such as speed, dance wildlife a d vehicles. These lenses work especially well with wildlife photography, since you have the ability to take a photo from far away from the subject which can be beneficial, since getting close to wildlife without disturbing them is challenging and they can get scared. Far away objects in a distance are able to be photographed since you have the ability to take a photo from up close, whilst still maintaning quality.



Wide Angle Lens

"In photography and cinematography a wide-angle lens refers to a lens whose focal length is substantially smaller than the focal length of a normal lens for a given film plane." 

Shooting with a zoom lens or even something similar to a 50mm prime usually limits what you the camera can take in. The first type of shot that springs to mind when you think about a wide angle lens is a landscape image. A wide angle lens will allow you to fully take in the entire room and also capture the essence of the scene, without zooming in and possibly ruining the image with concentrated up close subjects. Wide angle lenses take in such a wide field of view, they can distort the apparent physical relationships between objects within the framing of the image. This results in obvious distortion, most noticeable when you see lines that should be relatively straight but are instead bent. Essentially a wide angle lens allows the phtographer to capture the bigger picture. 

Medium Format Camera

Medium format cameras use film bigger than 35mm or digital, and thus give much higher quality within the image. Its almost just as easy 35mm and digital, and in some ways more advantageous. The quality is better than 35 mm or digital and almost equal ease-of-use for when using the camera, it is a popular format for many tyoes of photography including portraiture. 


Large Format Camera

A "large format" refers to any imaging format of 102×127 mm or larger. Large format is larger than the medium format, the 6×6 cm or 6×9 cm. Most, but not all, large-format cameras are view cameras, with fronts and backs called standards. Standards that allow the photographer to better control over the rendering of perspective and increase apparent depth of field. Architectural and close-up photographers use and beefit from this format also. 


Bronica Film Camera

Bronica cameras first appeared in 1958, when the company's founder, Zenzaburo Yoshino, introduced a camera of his own design. Bronicas were used for workhorse camera's and by wedding and portrait photographers for years. 

The most recent release of a Bronica is "extremely light and compact 6x4.5 cm coupled rangefinder camera system with four interchangeable leaf shutter lenses"
