Nikon D5200+10.5
Posted: 25 Jul 2013 at 13:00 GMT
Hi! I was forced to replace my original setup ( D90+10.5 stolen) with a D5200+10.5.
Happens that PtGui does not recognize the exif exact data. It recognizes the camera as a 5200 and the lens as a 10.5 but not the right crop factor. It detects the crop factor as 0,95238095 and not as 1,523 as it should.
When set at auto it detects the lens as a circular fisheye. I have to set it manually.
Any advice or hint what the problem could be?
Thanks and regards,
Martin.

That sounds odd Martin, Can you make one of the images available?

Hi Smooth!
Thanks. A single image of the 7 would be ok? I observed this trying to set up and adjust my NN to this new combo, so there are still minor adjustments to do. Tell me please what kind/type of image you need and how to make it available.
Thanks again!!

Just a RAW file straight from the camera will do. If you have shot .jpg that straight from the camera would also do. But I don't want a processed image.

If you have NPP problems I can look at that in a separate thread.

Great Smooth!
Here´s a link to download a simple NEF file. I had to convert it to dng as my PS version or ACR version does not support the D5200.
I hope it is usefull and of help to find out what the problem is.
Regarding the NPP, thanks for your offer. I´m close to find it, a few adjustments still have to be made.
If necessary I´ll be back, but first I want to understand what is happening with the issue about the exif data.

In the CS6 Bridge display of the NEF file exif data, the focal length shows correctly as 10.5mm but the 35mm equivalent is shown as 10mm. Hence the crop factor of 0.95238 (10/10.5) assumed by PTGui. The choice of lens type will be made according to the rules laid down in Tools->Options->EXIF. By default, in this case it will assume a circular fisheye. You can edit the rules so the correct lens type will be chosen. (In fact, either will work equally well). To work around this error, you can enter the details manually, or apply a template, or make use of the lens database to store/load correct parameters.

Martin,

What John is saying makes sense. I'm having a hell of a time trying to get your file. The download is so slow. Either the server is overloaded or our connection isn't great. Still saying I have over 1 hour to go!

Upshot is the EXIF must be wrong if what John states is correct. It should read 15.99mm or 16.00 at 35mm equivalent NOT 10mm.

So either follow the suggestions John has made or use a program to modify the EXIF data like PhotoME or Opanda.
Of course best would be to get Nikon to fix the error with their product.

The download was excruciatingly slow for me too: 25 minutes for the 24MB file on a 60Mb/s connection.

Thanks for the feedback and sorry for the inconvenience downloading the image.
Should you need more please let me know and I will send a jpg file.
Modifying the exif data each time sounds a little time consuming so the best way would be to create a lens database in PtGui. I just tried to do so, but it seems I´m missing something. Which should be the correct settings or parameters to input?
Does this sound to you as a problem of Nikon in this case or a specific problem of my camera/lens only?

Thanks again, Martin

To create a new lens in the lens database, first complete a good 360x180 stitch with the lens. Then visit the Lens Settings tab in Advanced mode and click on the Lens Database button. Type in a suitable name for the lens entry and click on "Save to database". This will save the current lens details from the project to the database. You can then load in these details in future projects.

If you are shooting many panoramas with the same configuration of shots, then using the project file as a template is a better option, as that initializes the image parameters too, so that the optimizer is off to a flying start with very little to do but fine tune all the parameters.

Could this eventually be solved by updating or reloading the camera firmware or is this to risky?

Martin, Updating the firmware is straightforward and safe, provided you follow the instructions provided. There's no firmware upgrade available at this time and it could be several months before a solution might become available. Meanwhile, it's no big deal. You can amend the fisheye type choice so that it gives the wanted fullframe result. Once that's done, all you need to do is enter the fov on the lens settings tab. Focal length and crop factor are completely irrelevant, as they are only used to estimate the fov, which you can copy from a successfully completed PTGui project. But as I have already suggested, applying a PTGui project file as a template after loading in your images is hardly any more work and generally helps to give more reliable stitching.

Any of the methods are straight forward. Personally I would modify the EXIF data. That is the heart of the issue and yes this is Nikon's error and a corrected firmware is needed. It is no big deal to update firmware and you should always keep your camera firmware up to date. (Is there one available?) Has the error been reported? I doubt the D5200 and Nikkor 10.5mm is a high usage pairing.

John, your 60Mb/s is a very long way from my 6Mb/s. I live in a country town quite a distance from the big smoke. I'm at the maximum limit of my exchange and yes it sucks. But they keep making promises.

The up side is any more than 4 cars in a row around here is called a traffic jam!

You can download your image with modified EXIF data and try.

ge.tt/3zC4Rtm/v/0?c

Very simple to modify using PhotoME

Try yourself:

Free Download: www.photome.de/



Open file>Click Camera (Tab)>Scroll to Focal Length in 35mm Film area>Click to edit



Change value from 10 to 16>Apply



Confirm>Save or Save As>Job done! smile

The EXIF of a sample image from a D5200 review using the 18-55mm kit zoom at 55mm showed the same issue - no allowance for the crop factor.
