仲有一個辦法，就是用 live view，甘樣，有無shift都無關係。

但系M240太貴了！而且某咩買NEX的打算。M對於我來講唔單隻系一個品牌，仲系一種攝影方式。快門時滯短同快門靜都算比較容易話圍。我最欣賞的系摁快門果一下同被拍對象的眼神接觸。我前幾日都有去Stanford玩A7同A7R，賣相唔掂，成部機揸上手都好hollow。。。

Thanks for your compliments! Actually I haven't figure out a good approach to process M9's files...

Focus shift on this lens is way overrated IMHO, this lens gives very good rendering and mates very very well with M9.

I owned this lens before, and search in web for the focus shift
in fact, I think it is not out-of-focus problem
but the un-even extend of DOF on both sides while changing aperture, that make someone feel the focus point change

My understanding is that it has both focus shift and severe field curvature. These are different problems.

Focus shift is very real. Under default setting, it has front-focusing below f/2.8. The standard way to deal with this is to focus a little in front (e.g at the nose tip rather than eyelashes when doing close-up portrait) at f/1.4.

Field curvature is a very different problem. It means that if the subject is not at or near the center of the image, the standard focus and re-frame technique may not work accurately.

All these problems are marginal. They certainly affect digital more than film. As a film user, you may not mind at all. As a digital M9 and Monochrom rangefinder user, I find it inconvenient. But then users of M240 and Sony A7 may circumvent these problems by live view.
