Professionals don't use M4/3?

I am not a professional in any sense but I think the reason many so called professionals do not use 4/3rds cameras and lenses has more to do with there history with photography.  Older professionals have a history of using only full frame SLRs with optical finders for viewing and expensive fast good lenses because the cameras were not capable of using higher ISOs.  Anyone with a large investment in full frame cameras and lenses would naturally be very reluctant to throw all that away and consider something smaller like m4/3rds.  In recent years cameras have advanced in capability to the point that even entry models are quite capable of producing professional results whether they be full frame, ASP-C, m4/3 or even 1" as sensors have become better and better, cameras likewise with exceptional capabilities and not every professional really needs super high resolution as not printing 4 ft wide billboard pictures.  In SLR days expensive and heavy fast lenses actually took poorer quality pictures then slower lenses but were necessary to use in low light conditions etc or where higher shutter speeds were essential to catch the moment.  Today the main advantage of the expensive professional full from or other lenses is to put the background out of focus sort of like modern art rather than panaramas where make depth of focus is more important.

The mark of a good photographer is the ability to catch the moment and not necessarily the equipment he is using to achieve that end.  Not so many years ago we did not even have auto focus or image stabilization but still the pictures taken in earlier eras were outstanding.  Yes there is a perception that professional photographers must have the very best and latest advances  and the m4/3 does not yet meet their standards.

I think that both Oly and Pany are currently making a mistake in paying too much attention to producing high end m4/3rds camera models and professional lenses at the expense of enthusiasts models if the format is to survive.  With the advent of Iphones have taken over the majority point and shoot compacts and this is also effecting m4/3.  There aren't many sources to track individual camera sales other than in Japan.  As recently as two years ago m4/3rds both Pany and Oly were dominating the interchangible lens mirrorless market. Now  I just cheched the DSLR sales ranking of top 80 sellers in Japan and noted that only the EPL7 and EM10 II were ranked while with Pany only the GF7 and at lower end a couple GM models.  None of the so call professional cameras like EM1, or EM5,or Oly Pen or Pany GH4 or GX8 were even ranked.  The EM10 II was the only new m4/3 model doing well in sales and that is because it is reasonably priced and affordable.  Pany is answering with the equally capable and affordable GX80 and that is the way to go if Oly and Pany are to survive and not concentrate in low volume high end models. These more affordable models contain much of what their top models have and even some newer  improvements in the case of GX80.
