Lecia M9 & Lux 50 - Infinity focusing & Front Focusing

Have anyone tried this and any comments for the following?

http://www.l-camera-forum.com/leica-forum/leica-m9-forum/122176-m9-coincidence-infinity-9.html

I have some front focus issue throughout the range on my Lecia M9 & Lux 50mm combo and furthermore it does in line when in infinity.

Presently, i tested that at f1.4 and i compensated back the front focus issue during the focusing. Once u got that, that is really bitting sharp and really stunning quality photo.

Of course mine combo set is under warranty thus will be sending back to Lecia Solm for combo set calibration, will that be solved?

Anyway will the above mentioned web be a good reference for future DIY.

Thanks & Cheers,
