Thanks B&H for a quick refresher, updated for the digital age. My first SLR (an old compact favorite) was the OM-1 purchase in the Mid 70s made by Olympus, before the digital age. Your article revealed digital capabilities new to me, example being ISO 25600. Besides, the rest was good refresher for someone who has been away from SLRs for a while and recently purchased a DSLR. Keep publishing.
