Let's put it this way. I'm an engineer, so I have some scientific schooling. For that reason I'm quite interested in how things work. I don't think it would be easy for me to arrange an unbiased test. I did consider renting MF equipment for a couple of days but that would set me back something like a full frame DSLR here in Sweden.
Also, I would say that making unbiased comparison images would be quite easy to do for any vendor, as they have most equipment in house.
Yes, you are right that I have no experience with MFD, although I have experience with MF and such being a long time Pentax 67. I did consider buying both Mamya ZD and Pentax 645D, but decided against it. The main reasons?
- Money, obviously, I could afford it, but perhaps not justify it
- Weight (I often travel by air)
- I use zoom, superwides and long teles, so either a big MF kit or DSLR + MF
- I don't print that large, normally A2
"What I don't understand is why MFDB vendors don't publish correct unbiased comparison images from MFDB compared to state of the art DSLRs?"
You are starting to sound like Fred... Why should they? MFDB dealers and makers offer their kits on loan to serious potential buyers for free. Is that not enough? Are you another one of the many MFDB antagonists that never used one themselves?
Do DSLR manufacturers publish comparison images? Can you get a free test of a new DSLR? Why do you care? Would knowing the answer to any of the questions in this or the other thread make you choose to buy or shoot differently? is your question only to satisfy some odd curiosity? It seems to matter so little, since there are so many other reasons to consider when choosing a camera.
