If you’re ready to put that tiny Nikon D4 to shame as if it were a cellphone camera why not get serious about your photography and step up to a real camera? I used to use the film version of this monster way back when I shot weddings and family portraits professionally. In fact I had 2 Mamiya 645 bodies and 3 lenses. The negatives and slides from these monsters were bigger that a Lipton tea bag in the paper envelope. They made 35mm film look pretty puny.
Do keep in mind that medium format digital cameras will require you to pump some iron just to be able to carry it around. Actually it’s claimed to only weigh 1.1 pounds. The real weight comes from your wallet full of money because this baby cost over $30,000. Arghhhh! 😦 Just what daddy needs in his stocking for Christmas.
