Macro photography is an interesting activity,to be able to reach into ‘near space’ and capture a picture that is not easily visible to the open eye is an attractive option.To snap macro in the days the requirement of using an SLR camera to take highly maximize pictures of extremely small subjects.
macro lens that was surrender to macro shooting; another option was to fit a reversing ring that allowed you to fit the lens on backwards ,this improved the lens close up resolution and allowed to you to focus much more closely.
In Macro photography, a sharp image of a small scale object requires the lens to be positioned much closer still, with the lens moved even further out than for normal photography.Set macro mode on a cam and the system adjusts the lens elements to re-arrange them into an array that best suits close focusing. Using a small lens aperture means we need more light,
so we need to extend the exposure time to make a correctly exposed picture.
With D SLR cameras the macro operation is some different. Select macro and we activate a different chain of events,with any lens fixed to the camera, engaging macro mode on the camera commands the lens aperture to close to its minimum, so extending the depth of field and allowing to move closer to the subject.
Shooting macro with a compact digital cam is easy but we have to forgot a fair bit of control and you need to understand that the demands of an amateur as far as resolution and quality are less.
Macro lenses are not cheap but they are optimized to operate at closer than normal distances.
With macro lenses we are unlikely to experience problems such as colour fringing and optical deformation,many macro lenses also compensate for the additional exposure necessary when racking out the lens to distances very different to those used in normal photography.
