Macro lenses are a specific type of optics - specialized equipment, but enjoying considerable popularity and are often used for more diverse applications, rather than showing the world is too small, so we can appreciate its beauty for yourself. Therefore, and in the editorial SwiatObrazu.pl much like a glass. This time, in our hands got very interesting, and at the same specific model: a macro lens designed for SLR camera bodies from Canon equipped only image sensor APS-C format and EF-S bayonet. We invite you all to read the results of our test this device.
Macro lens market is very diverse - this is probably the most extensive group of lenses, was not there, created with the aim of special pretty nature clear applications. However, very few glasses developed with the aim of a particular subgroup of cameras forming part of the system. An example of such a lens is relatively new (for optics) construction of Canon, which is marketed in 2005 model EF-S 60mm f2.8 Macro USM directed to users of matrices bodies APS-C format equipped with a bayonet EF-S (ie, all of this format SLR cameras manufactured nature after 2003, when it premiered the first camera of this type of attachment - Canon 300D). It is this lens came to our editorial office, so we had a chance to thoroughly test it. Canon EF-S 60mm f2.8 Macro USM connected to the body of the Canon EOS 50D - our test platform.
Described lens is available in retail at a price of approx. 1,700 zlotys (data for service Ceneo.pl) and those interested in its acquisition should keep in mind that it can not be used with EF bodies (ie including all Canon cameras equipped with dies periapical). The letter "S" in the name of this type of glasses is because the type of structures Short-back focus, in which the last optical element can slide while working in the mirror chamber more than allowed by the standard specification of EF. This involves the modification of a bayonet design provides compatibility EF and EF-S only in one direction - EF can be connected to the body EF-S. The standard assumption of developers aim was to enable optical designers to create lenses lighter, smaller, cheaper production and better co-operating with matrixes APS-C.
Although in normal circumstances connect the EF-S mount EF is not at all possible, it is among photography enthusiasts and DIY techniques are known to modify the lens mount on the camera allows the operation. Very we warn against similar procedures, since the use of EF-S lens with so altered body will end up damaging nature the camera mirror.
Canon EF-S 60mm f2.8 Macro USM lens is therefore cooperating only with cameras such as the Canon EOS 1100D, 650D, 60D, 7D and their "elder brothers". With a focal length of 60 mm model provides a field of view equivalent to the theoretical field of view lens with a focal length of 95 mm małoobrazkowego plugged into the body and has a brightness of f / 2.8 - so this is quite a typical small "stalk" of moderate Light intensity. Above all, however, this design with a minimum focusing distance of only 20 cm, provides scale mapping at 1: 1 and a minimum aperture ratio of f / 32, making it a full-fledged macro lens.
