Well I understand your point but my point is that I can use any lens in conjunction with PS. Looking at large prints I've made with and without PC (same image) I can honestly say that the print with PC applied digitally has lost no practical resolution in print. That's test enough for me. If you are shooting film for direct projection or conventional print then I appreciate the need otherwise practically speaking why would anyone persevere with a slow fixed PC lens which offers only 28mm FL and 12mm of shift when I have the option to apply very flexible PC to any lens with generally no visible degradation in print? Cheers,
