alexg Posted December 8, 2003 Share Posted December 8, 2003 Hi, Just wondering if anyone knows a simple way of converting digital camera focal length to 35mm format? We are having difficulties in matching cameras for photomontages when our clients gave their photos using different cameras. I mean, what happens is usually one client gave an image taken using Eos300D in 18mm, another one gave another image taken with Canon Powershot S30 in 17.5mm, another one with Nikon 3100 in 5.8mm, Sony Cybershot at 8mm. Most of the time we just have to spend lots of time just 2 browse here and there searching the equivalent focal length. Is there an easy formula for the convertion? Thanx Link to comment Share on other sites More sharing options...
nuno Posted December 9, 2003 Share Posted December 9, 2003 with ACDSee you can see it in "Properties" ---> "Exif Metadata"... there are 2 focal lenght info... one is the digital format and the other is the 35mm format. nuno Link to comment Share on other sites More sharing options...

Administrators Jeff Mottle Posted December 9, 2003 Administrators Share Posted December 9, 2003 This is what we use at Smoothe: http://www.panoguide.com/reference/lens_calculator.html I think this is more applicable to film negatives though. The second route is to do a quick calclualtion based upon your camera's Lens Multiplier Factor. http://www.outsight.com/hyperfocal.html#digital Link to comment Share on other sites More sharing options...
alexg Posted December 9, 2003 Author Share Posted December 9, 2003 Thanks Jeff ! That really helps solving a lot of problems. Sometimes I just wish all the manufacturers agreed on a single convention for their focal length. Otherwise the notion 3x zoom or 10x zoom is just so confusing, especially when you are used to using slr 35mm lenses. BTW, Nuno... the ACDsee works like a charm !

alexg Posted December 18, 2003 Author Share Posted December 18, 2003 Nuno I just upgrade to ACDSee 6 trial and for some reason ACDsee doesn't always show the slr focal length. I have a screenshot here (hyperlink below) of the Exif Metafile on Acdsee 6 Trial and it only shows the digital focal length screenshot Any ideas? Is it possible that this trick doesn't apply to all cameras? Link to comment Share on other sites More sharing options...

alexg Posted December 20, 2003 Author Share Posted December 20, 2003 No, they're using different camera It's ok, just got the table of conversion from some websites. Link to comment Share on other sites More sharing options...
luigimux Posted May 13, 2008 Share Posted May 13, 2008 Hi guys just to let you know Irfanview does the same as ACDSee. But you need to install the Irfanview plug-ins. Cheers, Luigi Link to comment Share on other sites More sharing options...
