Only YOU can gauge your passion ... and your
personal practicality / sense of responsibility is what tempers that passion, not someone else's. Personally I sure the hell don't have 3 million in my retirement account, and tend to live with less other stuff so I can have more photographic stuff... perverting the notion of "
Less is More" :ROTFL:
It seems to me that you need to think through the passion part ... is the motivation weighted toward materialistically having the best, or aesthetically doing the best? Big difference. (
"weighted" being the operative word, since it is bound to be both to some degree).
What you are considering is without a doubt the best there is ... and even if surpassed in 2 or 3 years, will remain a milestone of photographic excellence for many, many years to come. This isn't the same as even 5 years ago ... MFD is now in the stratosphere when considering a 60 or 80 meg large sensor DB ... and a tech camera with the latest optics is most certainly up to the resolution of these backs. If truly considering work primarily with a tech camera, then there is no other choice compared to the IQ backs ... the unique operational advantages significantly increases your chances of mastery IMHO.
However, the other part of the equation is determining your personal threshold for technical mastery ... which does involve some level of mechanical aptitude and attention to detail on a far greater level than you've experienced to date with your current gear. You need a head for this type of discipline ... and many who think they do, find they do not ... in the end deciding it is just to fussy and tedious. One man's ecstasy
is another man's PITA
Good luck!
