| p.1 #3 · Lightroom metadata question |
You ought to be able to select all photos that use a 35mm lens (using metadata filter) and if necessary deselect those shot with other brands or models of lens (probably based on the dates on which you owned the lenses more so than metadata). Then edit one of those images in Develop mode, set the automatic lens correction even if you have to manually pick the lens brand and model, and sync that change to the other photos.
The same process can fix your 85mm I vs II issues too, but it can be tricky to separate the f/1.8 lens shots from the f/1.2 lens shots unless you have actually used f/1.2 as the shooting aperture.
The hardest way is to use say Canon DPP to determine which lenses were used and note which photos applied to which lens. If you're lucky there will be separate folders or date ranges for the different lenses so that they will be easier to locate within Lr.
I would avoid re-importing into Lr if possible because that would trash all previous edits for those photos within Lr. Only do that if separating the photos according to actual lens used is harder than re-thinking and re-applying edits.
It seems that sometimes the data that Lr has about the photo does not identify the right brand/model combination and it needs to be told about the brand before it can select the correct model. Other times it has the brand but not the model. Other times it just works. I don't know where the problem originates.
