I have been browsing the metadata for my images in Lightroom and noticed some anomalies in the lens categories as below.
1 Why does a 30D read a lens as being 10.0-20.0 mm yet the 40D reads it as 10-20mm?
2 Again why two entries for the 50mm?
3 And also for the 70-300?
4 There is an 18-456mm lens listed which I know refers to a Tamron 18-200 I once had, but why does it list 18 to 456 since I have never used a teleconverter on that lens?
Any thoughts on this would be appreciated. Secondly does anyone know of an exif editor that will do batches? Thanks.
