HOYA PRO1D AC CLOSE-UP No.3 is a multi coated top class achromatic (AC) close-up lens for professional macro photography using either digital or film cameras. Achromatic (AC) close-up lens consists of 2 sandwiched glass elements that create higher quality sharp image compared with that shot with common close-up lens by minimizing chromatic aberrations. Completely clear optical lens element inside light aluminum frame will let you get closer to the object and capture the image that cannot be done using only master lens, due to minimum focusing distance limitations.
Close-up lens is an extremely convenient tool that is by attaching to the front part of the master lens allows you shooting in macro style. In another words, close-up lens makes the original minimum working distance of your lens shorter, that will allow you to get closer to the subject and shoot it with bigger magnification. Close-up lens will let you get in a new world of creativity, providing detailed close-up shots. Suggested for shooting flora, insects and small objects.
* Combining close-up filters with other filters might cause vignetting.
Focusing distance reference table when using close-up lens*
|Close-up lens No.||Shortest focusing distance||Longest focusing distance|
|Without close-up lens||50cm||Infinity|
|HMC CLOSE-UP II No.1||33cm||100cm|
|HMC CLOSE-UP II No.2||25cm||50cm|
|PRO1D AC CLOSE-UP No.3||20cm||33cm|
|HMC CLOSE-UP II No.4||17cm||25cm|
|MACRO CLOSE-UP (No.10)||8cm||10cm|
* The above calculation is based on master lens with the shortest focusing distance 50cm. The shortest focusing distance shows the distance between the object and the front part of the lens.
Close-up lenses No.1 and No.2 are suggested for the lens with the shortest focusing distance 1m and more.
Close-up lenses No.3 and No.4 are suggested for the lens with the shortest focusing distance 30-50cm.
Close-up effect is the weakest when the lens with short focusing distance is used.
