I have tried to keep completely out of this debate but your comments below
You have both.
When you have a project that meets the following qualifications which do you use?
- doesn't require high ISO or video
- is personally important to you
* doesn't have a tight deadline, and you have the time to do things the way you want to do them
Well that just floored me and personally sounds like a man clutching at straws.
I own a Leaf Aptus75/Mamiya RZ kit and a Nikon D800E & D800 and I would be using the Nikons on any project be personal or for a client.
I have made a packed with myself that if I donít use my Leaf Aptus75/Mamiya RZ kit in the next six months its all going on Ebay as my Sinar P2 kit and Mamiya 645AFDII kit have already gone.
While there are many who no longer shoot medium or large format at all and exclusively utilize a 35mm DSLR, there are others who desire and even require using something different as well. While Doug's examples may not have rang true with you, I think his meaning is that a photographer may choose a different camera for different conditions, depending on those conditions and the applicability of a given camera system. I believe that has been a traditional approach for photographers for many, many years.
While perhaps the crafting of his message was not perfect, I understand his meaning and am not thrown by it. The idea that one is clutching at straws to desperately try to convey a reason to shoot medium format seems kind of extreme, but I can understand your reaction, given the set of conditions that were listed. The fact is - photographers who choose to use medium format do so for many reasons, rational ones, logical ones, even emotional ones. In an odd way, I think emotion is a key factor in equipment use.
Edit - I mean, not actually in an odd way, I think it is prevalent; odd only in that it doesn't get discussed much, nor can a manufacturer easily present it as a feature, but the emotional response to products is naturally very substantial.
