of field of these cameras is an advantage for macro work. The high pixel density and resolving power of these cameras' sensors enable them to capture very high levels of detail at a lower reproduction ratio than is needed for film or larger DSLR sensors (often at the cost of greater image noise). Despite the fact that many of these cameras come with a "macro mode" which does not qualify as true macro, some photographers are using the advantages of small sensor cameras to create macro images that rival or even surpass those from DSLRs. Macro photography can also be carried out by attaching a camera to one optical path of a binocular microscope (stereo microscope), making use of the optics of that instrument as the imaging lens for the system. Between approximately 1976 and 1993, the manufacturers Wild Heerbrugg (Switzerland) and subsequently, Leica Microsystems offered a dedicated microscopy system for macro photography, the macroscope line, with improved optical performance for photography at the expense of the stereo imaging facility of the stereo microscope; this system came with a range of dedicated stands, objective and supplementary lenses, and illumination systems. Following its discontinuation in 1993, Leica continues to offer similar products under the names Z6 APO and Z16 APO. The iPhone 13 Pro series introduced macro photography in the iPhone camera, as well as Samsung Galaxy S21 Ultra, which is also introduced a macro photography in the smartphone camera. Macro photography techniques 35 mm equivalent magnification 35 mm equivalent magnification, or 35 mm equivalent reproduction ratio, is a measure that indicates the apparent magnification achieved with a small sensor format, or "crop sensor" digital camera compared to a 35 mm-based image enlarged to the same print size. The term is useful because many photographers are familiar with the 35 mm film format. While a "true" macro lens is defined as a lens having a reproduction ratio of 1:1 on the film or sensor plane, with small sensor format digital cameras an actual reproduction ratio of 1:1 is rarely achieved or needed to take macro photographs. What macro photographers often care about more is simply knowing the size of the smallest object that can fill the frame. To put it simply, 1X magnification means: if the object is 1mm long, it would be exactly 1mm long when projected to the sensor. Let's say you are shooting 1X magnification with a full-frame
