35mm equivalent in EXIF data

rcflood · April 20th, 2005, 08:34 PM

Today I noticed that some 35mm equivalent fields seem wrong... on some cameras it's right.. for instance one user had a Minolta A1 and his landscape shot said 35mm equiv of 28mm which appeared correct. But I also saw some Canon D30, 350D, and 20D photos which said stuff like:

Focal length:50.0mm (35mm equivalent: 119mm)

Which is way off for those cameras (1.6X focal crop multiplier).

Is this a bug?

That data comes right from the camera which is written to the pic so I dont think its a software bug

I guess Canon encodes the sensor size wrong (I think that's what it's using to multiply the base focal length value by). Oh well. Thanks though

I have the same problem and it drives me nuts...Has anyone come up with an explanation of this?

"35mm equiv." EXIF showing wrong.

Something I learnt along time ago search is only as good as the words you use LOL

I have trouble searching for things when users ask a question on something I know has already been posted so no biggy.
