...can anyone help with an adapter to Sony that is accurate at infinity (ie infinity on the lens is infinity in practice?). I have 2 and both focus past infinity, which makes focusing by distance, zone, or hyperlocal, more complicated than it should be...
With any macro helicoid adapter you can use the helicoid to set infinity to the hard stop each time you mount a lens. All macro helicoid adapters have very stiff helicoid ring movement, so once you set infinity, it should stay there:
– Attach lens and set lens focus ring to infinity hard stop
– Set lens to widest aperture
– Use EVF to zoom in to infinity/horizon
– Without moving the lens focus ring, move the helicoid until infinity focus is perfect
– Don't move the helicoid again and use the lens normally
– Repeat each time you mount a lens and/or after you've used the macro function and moved the helicoid
Another option: Hawk's Factory macro adapters for M lenses have a hardware-adjustable infinity position. I have one for M to Leica L-mount, and it works great. The official Hawk's Factory site should be avoided – they're indefinitely backlogged and your order will just sit there with no contact from the company. I don't see an E-mount version for sale on eBay right now, though.

Some people shim their adapters to get perfect infinity focus, but that's a bridge too far for me – I don't want to risk ending up with a slightly tilted plane of focus.

(hint: not good!) Unfortunately (for me) the Lux shows its age. I agree the SEM is a jewel of a lens.
