Canon EXIF info on Ipernity

Hmm, this doesn't seem to apply to the XTi model... I have:
10 -> 15.6
50 -> 78.1
200->312.5

Maybe just send a mail to someone from the IP team?

You're shooting jpeg aren't you ?

I've noticed that maybe it might be something to do with Adobe software. I shoot raw and process in Lightroom and I've seen other photos processed in Photoshop that exhibit the same odd behaviour.

I wonder if Adobe's Camera Raw routines muck up the multiplier in the exif information....

I am shooting RAW and use the Canon tools to convert to JPG. I think the multiplier is something that IP does maybe with a lookup table for different models.

Hmmm, interesting... You'd think though if it were a lookup table the results would be the same across all cameras of the same model though.

Ok, I've just done some tests as this has me somewhat curious.

The EXIF header contains the "Scale Factor To 35mm Equivalent" field on both jpg and raw files directly from the camera. On my 400D the value is 1.6

Files exported from Lightroom do not change the value of this field.
Files exported from Canon's Digital Photo Professional (ver 3) don't change the value of this field.
Files converted in Photoshop CS3 don't change the value of this field.

Therefore, it must be something in the Ipernity upload algorithm that's mucking up this field in the EXIF information. Most odd really. Not in the least bit important, just weird.

I've seen the same. For photos made with the 5D the value should be the actual focal length of the lens but it is far bigger. I have not tested but I also hink it must have to do with the way Ipernity handles EXIF data.

'tis very odd, that's for sure. Speaking of 5D's, I notice some fairly substantial price drops on that piece of kit recently - down to less than $3k (Au) now. Still too much for me though.

The new models 1Ds Mark III, 1D Mark III and 40D as well as the anticipation of a replacement for the 5D that goes with it will make the price drop even more I guess.

I'm thinking of adding the 40D to my menagerie when I get new lenses, as it's price has also dropped radically of late.

I wonder if you can get refurbished 5D's in Australia... A 5D is my dream camera - full frame and weather sealing, and not hugely bulky like the professional series cameras.

Well the 5D body is now down to $2950 new at Discount Digital in Sydney - d-d-photographics.com/canoneos5d.htm

Whereas the 40D is $1499. That $1500 difference is an L lens...

Mind you, the 5D is not fully weather sealed either, so the only advantage over the 40D is the full frame sensor. The 40D has partial weather sealing, anti-dust system, live-view (I'm undecided on this, although it could be handy for macro focussing) and 14bit colour.

Hey, the exif "35mm equivalence" field is now fixed - or at least on my latest shot (I've not checked older ones yet).
