FAQ

Which models of UV filters are compatible with Simera series lenses?

The Simera 28/35/50mm lenses are compatible with φ49mm UV filters. When both the lens hood and the UV filter are installed, they can be compatible with thin UV filters with a maximum diameter of 51.4mm, such as the "MC UV series" of MECO. The Simera 75mm lens is compatible with φ58mm UV filters and allows to install mainstream UV filters together with the lens hood.

Can the focus tab of Simera series be disassembled?

The focus tab cannot be disassembled. Since disassembling or assembling the focus tab involves the internal structure, it may damage the lens.

Do Simera lenses have electronic contacts?

There are no electronic contacts on Simera lenses. They are manual lenses.

How to adjust the stepped or stepless aperture function on Simera lenses?

When the lens is installed on the camera, toggle the block on the front of the lens. Toggle to the left, a moon symbol represents the lens is stepless ; and a sun symbol represents stepped aperture if toggling to the right.

How to convert the format when Simera lenses are used on APS-C cameras?

The equivalent focal length = the focal length of the lens × the conversion coefficient. For example, when a 50mm lens is used on an APS-C camera, the actual perspective obtained is 50mm × the format conversion coefficient of APS-C cameras. Usually, the conversion coefficient of Sony and Nikon cameras is 1.5, and that of Canon cameras is 1.6.
