Re: M8 Focusing question
Carsten, I think you mentioned that it is asking a lot of a rangefinder to be bang on accurate at the closest focussing. I have found that my lenses tend to back focus at close range and so I compensate by focussing just a little closer than the rangefinder suggests. This is most evident with my 35/1.4 Asph, with its 0.7m up close point and narrow depth wide open. Before I started using my 'focus tweak' method, ears tended to be sharper than eyes.
Sometimes it's just a matter of getting to know the personality of lenses and bodies. And if I need perfect focus up close, I reach for an R8.
Here's something to ponder (apologies to those who've heard this from me before).
A properly calibrated rangefinder places the focal plane in such a way that 1/3rd of the acceptably focussed zone is in front of the focussing point and 2/3rds behind. There is no ability for the eye to assess how the focus looks. It is an objective process. The 'middle' of the depth will appear to be behind what we focussed on. It might look like it is back-focussing.
With an SLR and when using a ground glass screen we focus subjectively and will tend to place the middle of the depth of field on the focussing point. We naturally tend to front focus a little.
Experimenting with this concept is not so easy with film. Step up the M8!
