I thought I would reach out to the community, as I am at my wit's end. Here's the situation: I bought a used Pentax FA 645 macro 120mm a few weeks ago to use with the 645Z. I tested the lens when I received it, and everything about it was great; it was as sharp as everyone describes it online.

Last week, I went outside and took a few pictures with the 120mm. They were well exposed, and when I reviewed them on the camera screen, they were looking great. I got home and started importing the 120mm files in LR ... what a disaster. See the test shot below. You will notice the centre of the image is ok, but the rest of it, my god..., it's all blown out.

Another piece of the puzzle is that LR does that to shots taken outdoors only. If I take a picture inside the house, it's processed normally by LR. Nothing to report.

Any idea why LR does that only to the 120mm files taken outdoors? Why is there such a difference between the well-exposed in-camera file and the one LR imports?

Thanks!

I have had Camera Raw do this on the same lens. Its not all the time but it does happen. When you click the lens correction check box some times it adds a reverse vignette or something . Best bet is to do the lens correction manually.

Looks like vignetting correction gone wrong to me.

I agree with the others that lens corrections are the culprit. The reason for the outdoors versus the indoors is most likely your shooting stop. Your outdoor shot was at f11 and perhaps your indoors shots are at f4? The generic lens corrections are generally for wide open shots. Most lenses do not need vignetting correction at f11.

Same exact problem I have, FA 120mm Macro, shooting f/11 in the studio, profile correction turns up that result. It's probably as a result of an engineer at Adobe screwing up a line of code somewhere, since with the amount of cameras and profiles that they maintain, it's not out of the question.

Not that it really matters, because this lens exhibits no distortion, and has no vignetting at the apertures you're likely to use it at. There is simply nothing for the software to fix.

Thanks everyone for the feedback. It's clear there's something wrong with the Adobe profile for the lens when it's shot around f11. I will do the lens correction manually if needed then.

Are you all up to date with your LR? I'm running LR CC and while this was an issue with LR5 in the past, I'm not getting this now.

[Kolor-Pikker]

Using latest LR CC version on Mac, and it does still happen.

[BrunoL]

Hadn't thought about that. I'm running LR 5.7 on Mac. Will be upgrading soon and hoping that will do the trick, but Kolor-Pikker is saying it's still an issue with LR CC.
