Focal range info in slideshow&fullscreen?

[akamenov]

Sorry if this question is dumb, but i've not found this option...
It seems that XnView dows not understand lens information (focal range) from EXIF... Is it true? Is there any workaround to display it in slideshow&fullscreen modes (maybe, taken from XMP, i dunno)?

Thanks for any answer!

For me it works (with almost all cameras i guess).
Focal Length ... - mm

but does not work with my camera (it 's also depend of the camera).
Focal Length 35 mm - exif data

In fact , it will be also a good idea to have the possibility to have a calculated variable Focal Length 35mm like :

Focal Length from exif * variable ... - like 6 * 6 = 36 mm equi 35mm

Sorry, i wasn't very clear expressing my question - i meant not the current focal length, but the whole focal range of the lens(like "55-200mm"), just to determine, by which lens the shot was made...

This data (the whole focal range), i think, is not already implemented into exif.
Because it is the camara who generate exif data, not yet the lens by the camera.

Well, in fact it IS implemented, Digital Photo Professional can see it. Even XnView can see it, but in some strange manner, in some XML tag in the 'XMP' tab...

Ok, thanks for this information then i can't help you !

Could you send me a sample?

Hello. I studied this question a little since creating this topic, and I realized that:
1) For jpeg's taken with camera (Canon EOS 350D) DPP sees lens information, and XnView sees it, but in strange manner -- as 'focal length short' for minimum focal range and 'focal length' for maximium -- both variables in 'makernotes' section. 'Focal length' in image section contains focal length used when capturing image.
2) For raw files, DPP sees lens info, but no other image viewing software does.
3) For jpeg files converted from raw with Adobe Camera RAW, lens info can be found in xmp information, but there is no way to show it in slideshow mode.
4) For jpeg files converted from raw with DPP, there is no lens info included.

So, there is no general solution to a problem. But it would be great if there were such opportunity for jpegs of types 1 or 3. Here are the links to the files (they are really small):
JPEG from the camera
JPEG by ACR

By the way, thank you a lot for your great software!

Which software show you correct focal range?
Could you post a sample where focal range can be viewed correctly.

Well, for 1st link posted in previous message (it's not just a black picture, it's a photo with lens cap on) DPP shows focal range correctly, and XnView sees that numbers (55 and 200), but they are misinterpreted (as i've already wrote)
for 2nd link (jpeg by ACR) no software shows focal range, but it's included in XMP info, which is also seen by XnView.

So, though it's possible to find out focal range, it would be really nice if this info could be seen in slideshow...

Ok, i'll add it. currently makernotes can not be used!
