Greetings to those posters wanting shots taken with a Hasselblad 50mm f/4 lens: the attached photo was taken with a Prontor 50mm CF len f/4, using a red or deep orange filter and tripod. I've used this lens a lot. I also have the 40mm, but stopped carrying that in my travel bag due to its weight, plus the fact that I started carrying a Horseman panoramic and didn't need the 40 for the ultra-wide shots anymore. Still have the 40, though. The 50mm was a favorite lens of Charlie Waite, the landscape guru.
Regards, Charles Freeland
