I suspected possibly my shutter has a short calibration life, maybe I'll ask the tech to look at it more carefully the next time around. For what it's worth, I did send it out to Harry Fleenor one time for shutter servicing, as well as using my own local guy. The service cycle remained relatively constant. It slow speeds begin sticking regardless after a certain interval usually around 3 years. I do use it commercially, maybe I should consider a digital shutter tester. When the slow speeds stick thought is pretty quickly apparent. I tend to use the Rollei more for B&W work & with color neg. material (which I print & get drum scanned for pre press work) so the latitude covers minor shutter inconsistencies. Unfortunately or fortunately I've been shifting over to digital. I have to say I much prefer the workflow of film & the look also, but it seems at least for commercial work a necessity for survival & not fall behind. It's a wave you need to ride. I called my pro lab the other day as I did not like the look of the prints from my 6x7 negs, I suspected they were digital output & yes he answered all film is now scanned & printed. The prints look sharper, but also much less smooth & not as nice overall. Disappointing. I think I'll go back to chromes now over color negs. Best, Frédéric
