Thanks for posting this Pavel, and I apologise for not responding sooner - I must admit the wall of text put me off a bit.

I think definitely sensor technology has allowed us to make the biggest leap forward. Back a few years, the "pros" wouldn't do a shoot with anything less than medium format. These days, advances in tech have allowed smallers sensors to produce image quality to the point where the sensor and megapixels is no longer the topic of debate - it's moved on to the actual systems and supporting accessories, lenses, and all the other things which you've mentioned.
