Silkypix exif data question.

Is there any way of getting Silkypix to include the lens name in the exif data when it generates a .jpg?

Silkypix Pro does record the lens data provided the lens writes it's data to the exif in the original file: Example below:

Silkypix V3 also records the exif in JPEGS. See below:

My, what a lot of quick launch icons you have

Is SilkyPix always accurate about naming the lens? Aperture will get it wrong with some lenses, e.g. my Sigma 10-20 is recorded as a Sigma 18-50.

Thanks for the reply Richard. It seems that Silkypix can still read the lens name, but Photome does not.

PhotoME can read the lens name out of a PEF.

Indeed so Chris, and that's great where I have the jpg and the pef together, but I tend to seperate them once I am happy with them.

If I create the jpg using PPL, Photome reads the lens name. If I create it with Silkypix which I prefer, it does not.

PhotoMe can read my PEFs, but misreads my sigma 120-400mm I think this is due to the chip in the lens.
The older I get the faster I was.

It's more likely that the problem is with the lens library in Photome. It used to get my 150-500 wrong, but now doesn't. Have you updated recently?

Anyone manage to get silkypix to recognise Sv mode ?
I get ExpProgram = unknown

Sigma use the same code for several of their lenses, I think it's because they just copy stuff rather than licence it, some of their lenses report as Pentax lenses.

I'm biased (:wink as I'm not a Sigma fan since owning several of their lenses and being dissatisfied with all of them.

Neither TAv or Sv are recognised, both are reported as unknown. I will report this with sample files to Silkypix UK for feedback to ISL.

Whether they do anything about it is anyones guess!

IDimager and PhotoME are the same. IDI says Unidentified and PhotoME says undefined.

Do we know this for a fact Richard?

It is frequently said that the problem with last year's version of Photome not recognising the Sigma 150-500 or incorrectly reporting it as a 70-210 or whatever was a Sigma problem.

On updating Photome, the lens is reported correctly, even on old photographs, so the problem was with Photome's lens name lookup table and not the lens.

It's what's been said by many others so I tended to believe it, but you may well be correct.

I will need to check this out on my old Sigma shots. I will have to fire up my archive drive, so will take me a short while to report back.

Quite a few lenses manufactured by Sigma will show the same ID in exif. Sigma reverse engineers all their products to avoid having to buy manufacturers "codes", so they use the same ID for some lenses.

It might also be due to Pentax unwillingness to sell their codes to third parties.

Sorry Yves - not in the example I quoted. There was a problem, the lens remained unchanged, the photo remained unchanged but Photome was updated, and the problem was solved. That means that either Sigma did not tell Photome the lens code, or Photome had a wrong interpretation of it.
