Hello

the anti-light diaphragm or the installation situation optics/scattered light diaphragm. In professional optics, the scattered light diaphragm is designed for the use of pole filters. Most professional optics, however, have professional rewards and can be used without stray light diaphragm. Not to mention the filter is the weak link in the optical system whose compensation increases the disperse light susceptibility of the optics behind it therefore many filters need a scattered light diaphragm but not the naked optics.

The problem of Step Down is that it can lead to vignettes, so step up rings are more common in filtering. Step Down is done with near lenses and frontal convergents.

No, the scattered light diaphragm originally intended for the objective does not fit anymore. It is either screwed into the original lens thread or clamped in or fastened on the outside to the lens mount with a bayonet or a clamping device. The step-down ring, however, has a ribbed handle ring for mounting, which is larger from the diameter than that of the lens mount, since the scattered light diaphragm no longer fits over it. If you take a scattered light diaphragm that fits into the front (smaller) thread of the filter, there is a risk of vignetting, especially in wide-angle lenses.

If she still fits. Why not?
