I am old enough to admit I shot lots of weddings with medium format (hassleblad) no af, no zooms, no ttl, no hss. I actually attended a few seminars with Dennis...yes he shot very fast, cranking his film advance with his eye in the viewfinder, he used the big mecablitz flashes with a battery pack so the recycle was fast. His mantra was to be "reactive, not proactive" his posed shots actually kind of sucked. The real challenge those days was loading your 220 film backs quickly while following the action at the same time...you usually carried three backs, reloading as you went along....heaven help you if you started the ceremony sequence with a half full back....quite unnerving to change mags when the bride is sauntering up the aisle at a faster than normal pace! There was also the problem of the dark slide...I remember shooting a killer sequence of BG formals only to realize i had left the dark slide in the whole time. And you never carried two camera bodies on you. Our average image count at a wedding was about 350....you really couldn't afford to shoot more, given processing and proofing....unless you charged 50 grand like Dennis did. In some ways, I miss it , because you had to be very deliberate and make each shot count....today we can afford to be quick and sloppy, hoping to get one good shot out of 10.
I adopted digital early, but only as a novelty in addition to the hassies....I was finally in heaven when the canon 5d came out ...a digital camera with good af, great resolution and finally a replacement for film...whoah, you could actually shoot a wedding with zoom lenses! and ttl was quite good too. The files from that camera were so good, that I still have a few of the old portraits hanging...honestly, you can't really tell the difference between that and a 40 mpx image at normal viewing distances.
