Customer feedback praises construction quality but reports mixed compatibility, along with concerns about infinity focus and lens alignment. For buyers adapting M42 lenses to Nikon F cameras, those concerns matter because the listing requires manual operation and does not establish that every lens combination will reach infinity focus. Aggregate ratings lean positive overall, but do not identify which combinations work.
