I tested crop mode as follows: K-1 with Sigma APS-C lens 8-16mm @ 16 mm (@ 16mm the Sigma covers FF)
3 pictures of bookshelves filled with books: FF gives 44.5 MB APS-C mode gives 22.2 MB 1:1 mode gives 45 MB So Mark Roberts suggestion is right: the camera adds just a cropping specification to the raw file. I expect, when shooting JPG there will be a proportional file size reduction comparing 1:1 to FF -- Greetz, Jos -- 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.
