Okay folks here's a question I'll throw to the floor.

I've finally been able to mount a fully manual wide angle lens onto my
Fuji X-E1 and I was testing with it this afternoon.

For the curious, this is what the combo looks like:

<http://pdml.posthaven.com/fuji-and-wide>

BUT if I try and 'zone' focus with it, the background is out of focus.

Facts: lens is M39 mount and mates to camera via a M39-to-Fuji X (FX)
adaptor. Camera set to Auto so you offer it some light through the lens
and it will correctly calculate the exposure. This is flawless. Lens set
at (say) f/16, and infinity mark on focus barrel is moved to the f/16
mark so that everything between the two f/16 marks should be in focus
according to depth of field.

Result: foreground is sharp, everything from about 20 feet away to
infinity is soft.

However: if I leave the infinity mark at maximum focus (eg lens set to
infinity focus), and stop down to (say) f/16, then everything from about
2 feet away to infinity is in sharp focus!

Supplementary question:

To mount an M39 lens onto an FX body, apparently there are two routes:
just by using a M39-FX adaptor. OR by using an M39-Leica M (LM) adaptor
AND a LM-FX adaptor as well. Wouldn't the two methods produce differing
lens flange - to - sensor plane measurements? I appreciate this question
really needs to be addressed to something like the Fuji forum, but
thought I would put it past the ,might PDML collective first.

Would an incorrect lens flange-to-sensor measurement create the zone-
focus issue above?

Many thanks
