500mm f/8 Telephoto Mirror Lens for Canon Rebel EOS T3i T2i T1i Xs Xsi Xti 7D T4i Description This Studio Series lens is computer-designed using a combination of lenticular light refraction andreflection optics–the same physics used in many professional telescopes.Combined with advanced manufacturing techniques, the result is a lens with very sharp picturequality with less color abberation which is considered the most harmful factor in the field oftelephoto photography. TheCatadioptric or Reflex Mirror Lens is a highly developed computer designed product, using the merits of both reflex optics and refraction optics. This gives you very sharp picture quality with less color aberration, which is considered the most harmful factor in the field of telephoto photography This lens is a highly complex, precision-made, optical instrument it is also compact and lightweight.It is ideally suited for wildlife and sports photography. It has a fixed aperture of f8. It comes witha soft pouch and three (3) rear mounted 30.5mm filters – ND2, ND4 and Skylight. FOCUSING YOUR LENSFocusing is accomplished while viewing the subject through the view-finder of your camera and rotating the focusing ring. Since the aperture is preset, you will find under certain light conditions a shadow appearance on the split-image section of your focusing screen. In this case, simply focus on the edges of your subject with the outer center of your fresnel prism.Note:In order to compensate focusing when normal focusing position may differ due to extreme temperature change, the focusing ring has been designed to allow rotation beyond tile fixed engraved marks of the distance scale, to avoid error, focusing should always be made while looking through the view-finderNote:No adjustment of focusing is necessary when taking infrared photography, as is required with normal lenses.LIGHT AND CONTRAST CONTROLSince the reflex lens is not equipped with a diaphragm system, the use of filter plays an important factor in the control of light and contrast. 3 FILTERS: ( INCLUDED)Normal ( IA Skylight ) : This filter should be used whenever no other filter is necessary.ND 2X and ND 4X ( Neutral Density ) : This filters control the light passage since no diaphragm system is provided in the reflex lens. Exposure factor is 4 times with a ND4X, i.e., the light in-take through the lens is decreased similarly as it, stopping-down a normal lens with an aperture, by 2 stops.Note:ND filters reduce light passage only, and the depth of field cannot be changed.OTHER FILTER YOU CAN USE WITH THIS LENS( NOT INCLUDED ) Y52 (Yellow ) : This filter is used when taking black and white pictures. It makes a blue background darker. Quite effective when taking shots of Clouds on a blue horizon.056 ( Orange ) : This filter makes Blue or Green color lines darker and, Yellow or Red color lines lighter than seen with the human eye. Quite effective when stronger contrast is desired.R60 ( Red ) : Used to express day-time scenery as a night scene, or emphasis and strengthen contrast exceptionally. Also, necessary when taking infrared black and white exposures.Note:In case the subject to be taken indicates too much light or over exposure as indicated by an exposure meter reading, or LED warning signal of the camera, adjustment of the light in-take is controlled by using one of the ND filters. When using a R60 filter with an aperture preferred camera. an aperture adjustment to the camera between +0.5 to +1.0 is required. EXPOSURE OR APERTURE ADJUSTMENT WITH TTL CAMERASSince tile aperture of the reflex lens cannot be changed, the exposure is controlled entirely upon the shutter-speed being used.The speed-dial is set according to your TTL reading. Both aperture and shutter priority automatic cameras will automatically set the right speed with its auto exposure mechanism, except a few models which it is necessary to operate on a manual function.In aperture priority or manual operation of a camera, appropriate shutter speed must be adjusted using 3 neutral density filter in case of over exposure readings or the camera’s LED warning light is activated.If your camera is a manual TTL system, then Simply follow the exposure indicator in the viewfinder by compensating with the shutter-speed. In case of excessive light beyond the shutter speed capability, attach a Neutral Density Filter to Reduce the overall light passage. CAMERA WITHOUT TTL SYSTEMWhen using a camera without a TTL system and filters, except for the normal filter, the exposure must be stopped down as indicated in the following table to the shutter speed indicated by a exposure meter reading, i.e., with the 300mm f5.6 Reflex lens, the setting would be f5.6. If a Y52 filter under daylight conditions is used, the stop-down will be 1. That is, if the appropriate shutter speed is metered as 1/1000 seconds using a single exposure meter with a f stop of 5.6, then, the shutter speed setting must be 1/500 seconds.
