Schneider 98SSLR-4.5" Set-Screw Locking-Rings (SSLR) permit you to attach large filters to wide angle zoom lenses without vignetting. The SSLR slips on the outside circumference of the lens barrel and is firmly secured by an internal screw.

It should be noted that Schneider also makes Direct Screw-on Adapter Rings that provide convenient access for Series 9 and 4.5" drop-in filters. Schneider Direct Screw-on Adapters, sometimes referred to as step-up rings, are mounted directly to the front thread of the lens and provide access to a universal or larger-size round drop-in filter.

Both Adapter Rings and SSLRs are precision manufactured using high-grade aluminum and are coated with a black anodized finish.

Unlike other adapters, in which the aluminum set-screw eventually strips the threads of the aluminum ring, SSLRs contain stainless-steel threaded inserts and compatible set-screws that prevent stripping, jamming and cross-threading

The durable delrin plastic internal lock-ring secures the lens firmly without marring the barrel. A wide variety of interchangeable locking rings are available to permit one SSLR Adapter to fit different diameter lens barrels

Q: 1. Has anyone tried this with the Sony FX3 or FX6? I'm interested in the possibility of using my older style Nikon AF-D Screw Drive Lenses in Manual Mode. I don't care about Auto Focus at all. I just want to be able to use them in full manual mode including manual focus.

A: The benefit of using the Monster Adapter LA-FE1 Magic Ring Nikon F Lens to Sony E-Mount is the automatic functions it enables. If looking to only use this in Manual Mode, a standard manual adapter would make more sense. Something like the Vello Nikon F Lens to Sony E-Mount Camera Lens Adapter linked here would be sufficient. https://bhpho.to/3iaxSJH
