Several weeks ago I sold my 3 year old primary camera and flash days before their replacements were announced (timing is everything in the used market so my online research proved most beneficial). Nothing could have been more satisfying after another long work week than to receive my new camera today. I spent the better part of 2 hours learning the new features and programming user settings to my taste. Although the new model has dozens of improvements the most compelling are a highly improved auto focus system and significantly improved low light performance. The latter is the more valuable as it effectively makes all of my current lenses “faster” allowing me to shoot at four times the shutter speed under similar lighting conditions.
