Lens Detection - SIGMA 18-250mm F3.5-6,3 DC Makro OS HSM
hi guys
i purchased lens mentioned above universal , travel lens.
i did shots day , imported them lr4.
by default lens correction when importing lr4 detects lens "18-150" only, no make, no model.
i first thought: "damned, again problem, had stupid tamron lens" .... did import same raw (cr2) pictures in apple aperture , correct lens data here:
am doing wrong?
thanks help.

you not doing wrong.
executive summary: can still tell lr use particular lens profile regardless, , make automatic.
in more detail: successful lens recognition, lot of things need lined up.
- the lens manufacturer needs have lens report electronic id code camera, sufficiently unique - codes, 3rd party lens makers, might equally belong of several lenses.
- camera manufacturer needs record id code images, in valid manner. interpretation needed camera here (for example. older lenses may not report kind of electronic id, , camera may have general kind of lens mount base information on).
- lightroom needs take whatever code camera has written image, , compare against own list. images show given code, description written next in list. if happens vary actual lens used, lr has no independent way know that. functionally speaking, @ least pictures reporting id have been distinguished.
then: can control on lens correction profile gets associated id. if no profile @ applied; or wrong one; can intervene , manually select 1 want. can make selection happen automatically in future. done in setup menu within profile tab of lens correction panel: option called "save new lens profile defaults".
this tells lr use current image's profile selection template, other similar images in future (so far lr can tell lens id found) ... regardless of particular description may showing (perhaps, incorrectly) against lens.
it (separately) possible manually correct lens description, against imported images, despite failure of above 3 steps. example, there's lr plugin called "lenstagger".
but don't know if possible edit lr's recognition list, desired description in first place.
