Hi All. Having only returned to analog photography about a month ago, I've just bought a Bronica ETRS with the 645 back and two lenses, the Zenzanon 40mm and 75mm, all of which arrived this morning. All seems to be ok, but I have noticed that it takes less than a complete rotation of the crank to cock the shutter. Is this normal for the 645 back? I presume it is but I thought it might be wise to check. And with the 75mm lens, I've found that the plastic bellows like affair inside the lens hood makes it impossible to get the to get the lens cap off. Is there some knack to removing and fitting the lens cap with the hood still on or can I only use on or the other at any one time? ChrisB.
