PhotoShop - lens question
« on: November 25, 2010, 08:28:31 PM »
Please move if I have posted in the wrong place.

I Photoshop raw converter it shows me (top right) my exposure / f stop etc but it also tells me the lens i.e. 70-400  or 24-70  BUT  when I go to process shots which were taken with the Sigma 70mm it states it's a 100-300 (70mm)

I know it doesn't effect anything but now I have noticed it I find it annoying (pedantic I know) anything I am missing to correct this?  Thanks

David- there is nothing you can do. Adobe has included the most common Sony lenses with its raw converter. Nevertheless, the lens is sometime (or better regularly) mistaken for a Sony lens. If you can just learn to ignore it.

The problem is down top the fact that Sigma do not licence the A-Mount, but instead reverse engineer their lens chips from something similar in the Sony / Minolta lineup.

So when Photoshop (or Lightroom) check the Exif, it gives hte ID of the lens that was used fro the reverse engineering.

Note that in Lightroom (and I suspect Photoshop will be the same) if you use XMP files to hold the RAW edits you can simply go into any that have the wrong info and edit the relevant xml tag so that it has the right lens text.
