I have a Sigma 18-35mm f/1.8 DC HSM in a Canon 70D body. I have recently upgraded the lens firmware via the Sigma USB mount from 1.x to the latest 2.03 version (changelog: https://www.sigma-global.com/en/download/lenses/firmware/popups/a_18_35_18/).

The new firmware apparently changed LensType, which causes the lens to be misdetected. I am attaching the output for two raw files, one before and one after the upgrade:

As a new data point, another person experienced the same after the firmware upgrade and reported it to exiv2: https://github.com/Exiv2/exiv2/pull/458/commits/4f1a907792fbed08360447f5725bc1d677a040a8

Great, thanks.  I'll add support for this in the next release.

Hi, for photos taken with the Sigma 17-70mm f/2.8-4 DC Macro OS HSM (not the Contemporary version) on a Pentax K-70, I get the following value for both Lens Type and Lens ID: Unknown (8 24).

[Phil Harvey]

Great, thanks.  This will be added in ExifTool 12.14.

Hi,

I noticed that on my Nikon D3500, the Kit Lens AF-P DX 18-55mm f/3.5-5.6G  is reported as "Unknown (A1 40 2D 53 2C 3C CB 86) ". I checked with a friend wo bought the same Nikon D3500 half a year  later, and his AF-P DX 18-55mm f3.5-5.6G lens is detected properly. So maybe there are two versions of this lens?

Also I used a quite old Sigma Zoom lens (Sigma ZOOM-K 70 ~ 210mm f/4 ~ 5.6) on a Nikon D70. This combination is reported by Exiftool 12.25 as "Unknown (02 3B 5C 82 30 3C 02 00)"

Thanks for all your work on ExifTool!

Hi Daniel,

Thanks!  I'll add these 2 lenses.

Hi Phil,

Pentax has released three new HD Limited Full-frame lenses that are updates to three existing SMC Limited lenses. It looks like Pentax basically modernized them to the more recent coatings and added curved aperture blades. I have two of them the 31mm and the 77mm, and exiftool still assigns the old smc lens type and lens name.

I don 't get an "Unknown" message, just the wrong (old) lens text, and I am not expert enough at exiftool to discover how to force the numeric ID to see if there is actually any way to distinguish between the old SMC and new HD versions.

Old lens name: smc PENTAX-FA 31mm F1.8 AL Limited
New lens name: HD PENTAX-FA 31mm F1.8 Limited (note that they dropped the "AL" designation on the HD version)

Old lens name: smc PENTAX-FA 43mm f/1.9 Limited
New lens name: HD PENTAX-FA 43mm f/1.9 Limited

Old lens name: smc PENTAX-FA 77mm F1.8 Limited
New lens name: HD PENTAX-FA 77mm F1.8 Limited

I'm on a Mac and reasonably well-versed in command-line Unix, so I have managed (in my case) to just use exiftool to overwrite the type and name with the correct new lens name string for my own purposes, but I wanted to help the community and keep exiftool up to date if possible. How can I determine the raw lens encoding information for these new HD Pentax lenses and see if there is a way to distinguish them from their SMC predecessors?

Thanks,
John

Hi John,

Can you upload original JPG samples from the lenses that you have so I can take a look?

- Phil

[jcr]

Thanks Phil,

Attached to this message, straight out of camera (high compression/low quality for attachment size limit reasons) sample JPEGs shot on the K-3 mark III:
JCR_810.JPG shot with the HD PENTAX-FA 31mm F1.8 Limited
JCR_811.JPG shot with the HD PENTAX-FA 77mm F1.8 Limited lens

Sorry I don't have the 43mm version to provide a sample.

John

I was hoping there would be a LensModel tag or something to differentiate these lenses from the smc versions.  But I can't see any way to do this.  I would say that Pentax (Ricoh) dropped the ball on this one.
