IMHO the 645 pro is a far more appealing camera than the AF. although the AF is a lot more high-tech, the 645 pro feels like a professional camera. fully modular, well weighted, lenses like a 2.8 300 and 1.9 80, and working L/S lenses 20 years ago!
i wonder how they went so wrong with the later models. Im sure they will keep working on the AF to make it appealing again, but why they threw away a lot of nice features with the AF.
the AF still looks like a students solid works project.
Don't disagree about the AF as I have pointed out before.....http://www.captureintegration.com/category/steve/
But that said, it does focus, meter and take the picture when you press the button, and the fact it takes an amazing assortment of lenses, including all of the lenses that will work on the 645 Pro, like the 1.9 80mm, 2.8 300mm, Hasselblad lenses, etc, it's a worthy consideration when you factor that an AF camera kit with an 80mm lens only adds $2,000 to any Phase One or Leaf digital back.
Otherwise, the DF is a product that has clearly graduated with honors
, so while it does cost a bit more than an AF, plug that in if a nicer camera is desired. It still works with all of the above lenses.
If nothing else, this option allows you to consider every digital back on the market instead of only one.
