Originally posted by lawsonstone I have a question for those who've done this fix with the DA*16-50mm, as I have. It works, of course. But when I bring the raw images into Lightroom, I notice the lens data is not visible. Is there any reason why this fix might prevent lens data from coming over?
What body are you using it with? I recall some software having problems on identifying newer Pentax lenses when used on a screwdrive-body.
If you look at exiftool's
lens tag listings for the 16-50 da lens, you'll find that there's a number of entries:
'4 242' = smc PENTAX-DA* 16-50mm F2.8 ED AL [IF] SDM (SDM unused)
'7 242' = smc PENTAX-DA* 16-50mm F2.8 ED AL [IF] SDM (SDM unused)
'8 242' = smc PENTAX-DA* 16-50mm F2.8 ED AL [IF] SDM
The 4 242 was reported on pictures taken using the *ist D body while 7 424 was what was reported on a K20D. These were fixed to exiftool about a year ago (versions around 9.17 and 9.23), but I'd guess that many other programs, such as Aperture and Lightroom might not yet know about this.
Can you send me a sample image and I'll check what is being written to the lens tag.
