Why change? She is the best model I have seen in years and you two work together so very well. Never change. Keep her as long as you can and keep the 6008AF, too. I am amazed at how well it does its part of this job. I use the 6008 I which is OK. but your use of the AF is probably cause for Rollei to start at making them again.... I know I'd buy one!.... superior work... Logan
