Overview

The NiSi 111083 43mm Adapter is a purpose-built step-up ring designed to bridge the gap between lenses with a 43mm filter thread and the NiSi M75 75mm filter system. The M75 system uses a 67mm main adapter ring as its base, and this adapter screws onto your 43mm lens thread on one side and connects to that 67mm ring on the other, giving smaller lenses full access to the M75 holder and its range of 75mm square and graduated filters.

Constructed from aluminum alloy, the adapter is lightweight yet rigid, ensuring that the filter holder sits securely without play or looseness. This is particularly important for long-exposure photography, where any movement could compromise image sharpness. For photographers who shoot with compact or mirrorless camera systems featuring smaller lens threads, this adapter is an essential link in the chain that opens up creative possibilities like graduated ND filtration and polarization using the M75 platform.

Frequently Asked Questions

No, this adapter is specifically designed to connect to the 67mm main adapter ring on the NiSi M75 system. It is not intended for use with other filter holder systems.
Because it steps up from 43mm to 67mm, the significant size difference means vignetting is unlikely on standard lenses. However, results may vary with ultra-wide-angle lenses.
No, this is only the 43mm-to-67mm step-up adapter ring. The M75 filter holder and any 75mm filters must be purchased separately.
