According to jmacon the beta version 353 of SGP seems to run great, especially regarding Auto Focus – and that’s really fine!
Now one important wish that has been requested by numerous users (actually it seems to be one of the most frequently wished improvement related to the topic ‘focus’) is left for the 3.1 release:
Until now we often have the situation that the last focus position of the preceding capturing session is far away from the best focus at the beginning of a new capturing session because temperature is deviating strongly. If this deviation is large enough, it will cause the AF run to fail.
PLEASE, let the user specify the complete temperature -> focus position function
fp = f(T)
(see New order of sequence start events (3.1 beta) for the details).
Realizing the present feature request would enable SGP to calculate the focus position that corresponds to the current temperature and set the initial focus position (directly before the first AF run is started) to this value. Thus the focus position is exceptionally set to an absolute value. After the first AF run succeeded, temperature compensation (if enabled) continues to be performed relative to the last valid result of an AF run – just as currently.
Users never again would experience a bad-centered AF run which can fail to yield a valid result.
