If I wanted to go very light and still have some computing power for image review, I would use the iPad and camera connection kit as a travel backup device. My 64G iPad normally has over 40G of empty space on it and can read all my Olympus .ORF and Ricoh .DNG raw files. I can even edit them to some degree with apps like Photogene and Photopad, and Photosmith lets import, sort, grade and add annotation which then links directly to Lightroom.
Obviously, this solution only works until the point where you run out of storage space then you must have a computer to move all the data to some other storage device. 32G of card storage in the E-5 nets about 2100 raw exposures, or about 1800 GXR exposures ... that's generally more than I need for a three week long trip unless I have specific assignments to cover that are going to need a lot more study. -- Godfrey godfreydigiorgi.posterous.com -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
