Lens profile in db but says Uncalibrated Lens underneath

[marbly]

How annoying!

I'll have a play with this on my Win7 box and see if I can get it to work.
I have it working like this for my Pentax / Tamron combination.

Hi
I have it working with following entry replacing the existing in profile_genericSLR.txt.

I was confused by the large number of listed Tamron lenses for a Sony A700 combination and only realised belatedly that there were two groups of listings for Tamron in the drop-down list. Yours is towards the bottom of the list.

That is a different Tamron lens. Your calibration is for the 18-200mm, but I am trying to get the 18-250mm working. It isn't clear why before making any changes it works for the Nikon D300, but not the Nikon D70 and Sony A700. All are 1.5x DSLRs.

By the way, yes I backed up the original file before making any changes.

Hi,
New spectacles needed!

With the settings below I can get the Tamron AF 18-250mm f/3.5-6.3 Di II LD Aspherical (IF) Macro lens showing as calibrated with either Sony a700 or Nikon D70 set as Camera.

In all fairness I am not reading in the EXIF information from an Image, simply setting the drop downs to match your expectations. An un-calibrated lens shows as such and this lens appears without the 'un-calibrated lens' rubric.

Not sure I can offer anything more.

Hello,

I were to start a new topic when I discovered this one. I think it may be the good place for my question...
It seems adding one's own data into the file doesn't worke everytime.
For instance, my Tokina AT-X 270 PRO II lens exists into the profile_nikonlenstable.txt file :

25 48 3C 5C 24 24 1B 02|Tokina AT-X 270 AF PRO II AF 28-70mm f/2.6-2.8

So, using Hugin, I shooted a suitable pattern and let it compute the correction values for 2 focal lengths (70 & 50 mm).
Then, I added the following lines to the profile_nikonSLR.txt file :

begin lens
group: nikonSLR
multiplier: 1.0
aperture: 2.6
calibrated: true
menu_lens: Tokina AT-X 270 AF PRO II AF 28-70mm f/2.6-2.8
cal_abc: 28 0 0 0
cal_abc: 31 0 0 0
cal_abc: 35 0 0 0
cal_abc: 50 -0.002000 -0.001000 0.000000
cal_abc: 70 0.028000 -0.085000 0.078000
end

But, after loading ASP, the lens doesn't appear into the lens menu (see attachment), nor is detected.
And, yes, I noticed the 2 entries referring to Tokina AT-X PRO & Pro AF 28-70mm f/2.6-2.8, but they were there before I added the above.
I did the same for my 20mm AI-S lens, and it was correctly listed and recognized.
Why could make the tokina one not to be detected / listed ?

Regards,

J.-Luc

Somewhat unrelated but in the lens profile list there is an uncalibrated entry for "Konica-Minolta AF 18-70 f:3.5-5.6" and a calibrated one for "Sony 18-70 f:3.5-5.6". They are the same lens actually and thus you can use the Sony calibration also for the K-M.

Also, using the A700 I see that sometimes the lens is not detected correctly. K-M AF 18-70 often appears as Sony 18-200.

I am sorry to be so late in responding. Somehow I missed seeing your reply.

My profile_genericSLR.txt entry for this lens is identical to yours. I have verified that the file has been updated after saving it. If I manually select Sony A700 and Tamron AF 18-250mm f/3.5-6.3 Di II LD Aspherical (IF) Macro it still is reported as uncalibrated.

As a reminder, before editing this file if I manually select Nikon D300 (1.5x DSLR, same as Sony A700) and Tamron AF 18-250mm f/3.5-6.3 Di II LD Aspherical (IF) Macro it is reported as calibrated. Actually, for Nikon there are 2 Tamron 18-250mm entries in the menu right next to each other. If you select the first one then it says it is calibrated, but if you select the second one it says it is uncalibrated. If I select Pentax K7 (1.5x DSLR, same as Sony A700) and Tamron AF 18-250mm f/3.5-6.3 Di II LD Aspherical (IF) Macro it says it is calibrated, but the second entry for the same lens says it is uncalibrated. Selecting Sony A700 though there is only one Tamron 18-250mm in the menu.

Now for another anomaly, after I add the one line to the Tamron AF 18-250mm f/3.5-6.3 Di II LD Aspherical (IF) Macro that you suggested all non-Nikon lenses disappear from the menu when you select Nikon SLR. All non-Pentax lenses disappear from the menu when you select Pentax SLR. But, when you select Sony then the list of lenses in the menu remains the same (Sony, Tamron, Sigma, etc.).

Hmmm!
Interesting ...
Alas I can offer no explanation.
It might be worth while re-visiting http://support.bibblelabs.com/forums/vi ... 94&t=15277. This is a very old post, but still the only one giving any real guidance on the issue. Look for postings by 'cvermillion', Colleen was the expert on these things until she moved on to other pastures.

Personally, I simply created a new profile_pentaxSLR1.txt file for my camera and lenses, and edited profile.txt to include that file. Thus making it impossible for the software to get the guessing game wrong. Fine if you only have a single camera and only a couple of lenses.
Attached file for you to examine.

You might consider starting a new Topic - How to update Lens Calibration Tables?
Alternatively send a copy of this discussion to

and ask for help from the developers.

Cheers,

I read an ASP review a few days ago where the reviewer mentioned the impressive list of profiled lenses. That is the problem with so many reviews. They are so superficial. The reviewer was obviously fooled, just like me, when he looked at the list of lenses and didn't bother to even check if the lenses in the list were calibrated. If he had checked he would have discovered that many of the lenses are not calibrated so, I suppose, they are there just to make the list appear impressive. Maybe Corel understood that most reviewers and people using the trial version would be fooled by this deception.

...so, I suppose, they are there just to make the list appear impressive. Maybe Corel understood that most reviewers and people using the trial version would be fooled by this deception.

I wouldn't say it is a deception. I don't know the situation now (I have no inside knowledge), but the Bibble team was small and relied to a large extent on customer input of images/ calibration figures in order to provide support.

My take is it is better to initially identify the lens correctly (although I realise that the automatic identification doesn't always work properly - but that is another discussion) even if there is currently no calibration as that can be added later and images then adjusted accordingly, if desired.

Hopefully with Corel behind things it should now be easier to get access to a wider range of equipment for support purposes.

Rick.

That would explain why there are lenses not calibrated. It doesn't explain why there are lenses in the profile list that are not calibrated though. It takes time and work to add lenses to the list that are uncalibrated. That is pointless work since it is meaningless unless there might have been a sales/marketing reason for it.

My take is it is better to initially identify the lens correctly (although I realise that the automatic identification doesn't always work properly - but that is another discussion) even if there is currently no calibration as that can be added later and images then adjusted accordingly, if desired.

Rick, please read through this thread. This is not about automatic identification problems. This is about manually selecting cameras and lenses that are in the ASP list and then finding that many are reported as uncalibrated.

Hopefully with Corel behind things it should now be easier to get access to a wider range of equipment for support purposes.

Hopefully Corel will fix the many bugs in ASP 1.0.0.39 (the lens stuff is only one area) and issue an update. If ASP didn't have so many good features already and so much potential I wouldn't care much about the bugs since the whole thing would have been uninstalled from my computer and I would move on. ASP is quite good though, but it is clearly beta or even late alpha level software that needs to be brought up to release quality, IMO.

[marbly]

This is just to update this thread. I recently downloaded 1.0.1.10 and discovered this problem of having lots of lenses in the db that are not calibrated still exists even though I reported it to Corel a long time ago. Here is a thread:

http://forum.corel.com/EN/viewtopic.php?f=90&t=46255

[Dutchmm]

I suspect that, for most users, the problem isn't the long list of lenses that turn out to be unexpectedly uncalibrated, so much as the short list of lenses they own almost none of which are calibrated or even recognised. I hope that AFX is planning to cover this topic comprehensively in the ASG! I have to say just knowing where the files are doesn't seem to be enough.

[afx]

I hope that AFX is planning to cover this topic comprehensively in the ASG!

Well, there is not much to do, explain what the files are for and why there is a difference between a detected lens and a calibrated lens and then move on to how lenses are calibrated.....
In contrast to BSG, there is a sample based on g3data and scilab. Basically what Fotolars described in the other thread. That really works like a charm and makes the whole process trivial.

a related problem ever since b5 is that one of my oly lenses is listed twice and one is calibrated and one is not. it always choses the wrong one and i have to manually select the the other.

Yes, I have noticed this also with at least one lens. There were 2 entries for the same lens, one said calibrated the other said uncalibrated. I reported it to Corel a long time ago. There may be others.

[grubernd]

..even though I reported it to Corel a long time ago.

really. so you asked for something and it didnt happen on the spot..
this world is going down fast..
