Hi,

I figured out that the Petax lens "HD PENTAX-DA 40mm F2.8 Limited" (Lens ID 7 208) is not recognized by Lightroom in Version 6.6.1.

It is not shown in the exif. There is no Lens Information (e.g. for filter reasons).

There only seems to be the older Version "smc PENTAX-DA 40mm F2.8 Limited" (4 251)

Could you please integrate this Information in LR?



Thanks,

Timo

I had the same problem with a HD PENTAX-DA 35mm F2.8 Limited, all it showed was smc PENTAX-DA 35mm F2.8 Limited. I had to make my own lens profile with Adobe Lens Profile Creator, available for free download on Adobe's site. It took some time, but it was well worth it. I submitted it to Adobe, but I don't see that they integrated it yet & its been a year ago. I can email it to you. It's not exactly the same lens as yours, but it would be better than nothing. Or you can make your own. It comes with charts that you can print & then photograph & then run it thru the software.

Hi Ken, thank you for the offer. I am not that much looking for the correction file. I am missing the lens information at all. LR says "unknown lens". That bothers me. Did your lens show any information about the lens in the LR exifs?

When I was still using Lr 5.7 it wouldn't display the lens used or the camera, a K3 II Pentax. I had bought the lens before the camera & was using it on a K20D. It recognized that camera, but not the lens, so I made my own Lens Profile. Lr 6 recognizes the K3 II. It really makes quite a difference when you have the correct profile in Lr/CR. The image is clearer, the vignetting is gone as well as most of the color fringe on high contrast edges. It's not real hard to do your own profile with Adobe Lens Profile Creator. You can get by with just 9 shots of the chart & it's all processed in the software & it makes a profile for you. If all you need is Lr to show the lens, you can download a plugin for Lr called Lens Tagger available for free from here:  http://www.essl.de/wp/software/lenstagger-lightroom-plugin/ Then your lens will show up in exif, but you still wound have a profile in the Develop Module, Lens Corrections.
