Slowly. I work with the JPG's which run 75 - 100+ MB and they are slow. Once open, processing (editing) is normal. The JPG's are good enough that I have not used the 3FR RAW's. All in all I am very happy with the camera. The photo of The Oregon Responder with its wide dynamic range is impressive. At least to me it is.
It cost a lot of money, it is out there in the land of diminishing returns, but I feel I got value for cost. As always, YMMV.
Thanks for asking.
I just tried my wife's PC using a 71 and 78 MB JPEG with CS5. It is very slow!Seems that prospective buyers should check this out before proceeding.
It would be a real pain to discover that one needed a new computer to process one's files from one's new camera. Nightmare territory, in fact.
I will try my wife's PC with the DPR sample files and see how it goes.
Her PC is a 12 y.o. Core2Duo with 8 GB RAM running Windows 10 Pro 64 from a SATA2 SSD, so about as slow as it comes.
