Hello, new to the forum. Just got an A7II earlier this week to use as a digital back for my film SLR lenses (mostly OM, Hexanon AR, and C/Y).
Was wondering if anyone had any experience with stacking a Leica M-mount to E-mount helicoid adapter with another adapter (eg. C/Y to M mount, or OM to M-mount). I know these helicoid adapters are more useful with rangefinder lenses that have a relatively long minimum focus distance, but could be of benefit to SLR lenses as well. By my estimation the extra 5mm extension should allow a 50mm to focus down to ~0.25m instead of 0.45, a 35mm to focus to ~0.15m instead of 0.3m.
