Need hints for manual focusing the Samyang 12mm
#1
Dear all,

 

a few days ago I got my Samyang 12mm NCS for the e-mount. I couldn't test it until today: unfortunately this week I had an emergency at home, my father got hospitalised in emergency sunday night and in my family we spent two sleepless nights (now he's at home in convalescence and things are going well).

 

Today I had a few minutes for a test en plein air. Clearly I've still to recover the stress of the past days, because I did a mistake in manual focusing (computing the hyperfocal distance at ƒ/2): all tests at ƒ/2 are a disaster, while those at ƒ/5.6 are very poor. I have some suspects that the lens might be a lemon, but there are high chances it was mostly my fault. Actually, thinking it over, the markings on the focus rings are quite disappointing: they go up to 1m (3ft) and then there's the infinity one. Nothing in the middle. Too bad, because there is room for one further marking in the middle.

 

Now, the hyperfocal distances for ƒ/2 and ƒ/5.6 are 3.6m and 1.3m. Do you have some hint on how to set them? Also, I've read that Samyang focusing distance markings are often inaccurate, and this worries me: for ƒ/5.6 I correctly calculated the hyperfocal and put the ring slightly beyond 1m, but if the ring is really inaccurate it could have been the problem.

 

Thanks.
