Some manufacturers mark the basic zoom lenses with the word Macro, but this is misleading and signifies focusing with less than 50cm. Real Macro is making pictures with a size ratio of minimally 1:2, meaning that an object 6cm in size will be 3cm on the negative. Some say that the size should be 1:1. For a 10X enlargement, 2.5cm will become 25cm in total and that is something quite good. But how to reach such an enlargement when a regular lens has a range of image of 1:4 in the best cases, often it is something less. The cheapest route would be to acquire a macro-conversion lens, which is a dioptric lens of a vergency of +1 to +5 dioptrics set in a filter rim. This end piece is screwed on to the front part of the lens. With a classic zoom lens having a range of 28-80 or thereabouts, you will achieve a range in the image of 1:2 of generally good quality. We do not recommend using macro-conversion with a telescopic lens, because this could result in a chromatic blemish. Even stronger conversion lenses are being manufactured (up to +10 DPT), these are made with two achromatic lenses and their price is therefore significantly higher. The price of a regular conversion lens is quite accessible. If you are serious about macro-photography, then you will have to purchase a macro lens. These macro lenses are special with a image range 1:2 or 1:1. these can be used for everyday photography. These lenses are specially constructed for focusing up close, they have a high level of differentiation and enable the setting of a high aperture for enlarging depth of sharpness. The most common focal length is one at 50mm, if you want use a macro lens for portraits, select the focal length of 105mm. If your specialization happens to be `hunting` insects for example, then you use a macro lens with a greater distance from the object (a distance of 180cm and more), this will allow a sufficient enlargement without having to get too close to the object and then scaring it away. The price of a quality macro lens is cca 400 EUR, something more than the price of a fixed lens and annular rings. Minolta produces a special lens at the range of 28-80 and 75-300mm with a macro setting with a 1:2 enlargement, this would be a good choice for the occasional photography of details. A lesser used solution is to use the reverse annular, allowing the basic lens to be turned and then stabilized by the front ring on the bayonet of the photographic instrument itself, each basic lens after being turned works as a quality magnifier. The problem then is the transfer of information between the lens and the camera itself. This solution is used mainly in the mid-format instruments. Macro-converters are also being manufactured, this is optical equipment which is inserted between the camera and the lens, and plays a double role. They extend the focal length of the lens something similar to a tele-converter, but they especially are useful for shots taken at close range. For quality shots up close a quality stand has to be used, we recommend those which allow pictures to be taken even at a very low height, a gentle and precise focus will be made easier with macro-shoes. When doing detailed photography, we often encounter the problem of quality lighting, and use various reflecting surfaces, mirrors, and flashes connected by cables. Also being produced though are the macro-flashes, which provide the greatest possibility of controlling the lighting. We use two types. The first is circular, made up of 2 to 4 light sources with the possibility of switching the individual ones, and in this way adjusting the arrangement of light and shading, the majority are with pilot lights, so that the photographer can judge the lighting before the actual exposure. The second type is made up of two light sources on the shoulders which can be tilted in various directions. Both types are mounted in the front on the rim of the camera. http://xbrain.fotopages.com/?entry=961819 Thu, 26 Oct 2006 00:00:00 GMT http://xbrain.fotopages.com/?entry=959855 Sun, 22 Oct 2006 00:00:00 GMT http://xbrain.fotopages.com/?entry=955633 Tue, 17 Oct 2006 00:00:00 GMT
