Reproduction ratio
Term used in macrophotography to indicate the magnification of a subject; specifically the size of the imag recorded on film divided by the actual size of the subject; for example, ...
Reproduction Ratio Specifically the size of the image recorded on film divided by the actual size of the subject. Resolving Power (Resolution) The ability of a lens or photographic material to reproduce small details.
Reproduction ratios
In order to quantify the performance of close-up devices (extension tubes in particular) the frame area covered is compared to the 35 mm film frame size.
Reproduction Ratio and Resolution (Skip if you don't care - it doesn't matter)
I shot at 5.6m (18.4'), or a magnification of 1:200 for the DSLRs and 650:1 for the SD700.
Reproduction Ratio: The ratio of the actual size of an object to it's reproduced size on film.A 1:1 ration means that the object is represented as life size on the film, a ratio of 1:2 means that the object is half life size.
Exact reproduction ratio and framing are nearly impossible due to fact that magnification and framing are done in 'steps' with the extension rings. The lens, in most cases, has little to no focusing available when in reversed position.
a at 1:1 reproduction ratio
b calculated or estimated value
c there was either contradictory information (general brochure vs. individual leaflet) and I chose the one more reasonable (to me), or there were obvious typos that I corrected.
The optical formulas of regular lenses are optimized for reproduction ratios less than life size.
Subject shot at 1:1 reproduction ratio (life size on film) with a 105mm Micro lens and PK-13 extension tube and Nikon F4.
Macro Taking photographs of small objects with regular or special photographic lenses at reproduction ratios of 1:1 or greater; also referred to as "macro" photography. Jump to Top Back to Previous Page

I use a Canon MPE-65mm lens that allows for up to 5:1 or "5 times life size" reproduction ratios which allows me to just about completely fill the frame with a single drop of water.
The magnification ratio, or reproduction ratio as it’s also known, is a crucial feature. True macro lenses offer a magnification ratio of 1:1, meaning your subject will be the same size as the image sensor it was taken on.
A lens for close-up photography; designed to focus continuously from infinity down to a reproduction ratio of 1: 2, or with a matched extension ring or teleconverter down to 1: 1; ...
Closest focusing distance is under five feet, which is exceptional, giving you a maximum reproduction ratio of almost 1:4.
Lens, Macro
A lens that provides continuous focusing from infinity to extreme close-ups, often to a reproduction ratio of 1:2 (half life-size) or 1:1 (life-size). See also Macro Photography.

For macro lenses or lens/elongation combinations the maximum reproduction scale (or reproduction ratio) is a characteristic parameter.
