I have a Panasonic GH2 and I couldn't be more happy with it. As for slow... whether you are talking about focus speed of aperture, I wouldn't agree on either.
In terms of focus speed, the GH2 is very quick with the latest generation lenses, apparently rivals most entry level DSLR's in most situations. As for aperture, yes, currently there is a shortage of fast lenses in the tele region(though the new lenses Pana is releasing soon should fix this) but the shorter lengths are covered with some great compact lenses. For my usage the shorter stuff is more important as it is usually what you want indoors. I've got the 20mm f1.7 lens and it covers me well in this regard, though it does suffer the occasional focus hunting issue. I've got the 14-140 lens which to me is a fantastic lens, offering a useful range, fast focus and good video usage, I use it for everything except low light or fast stuff.
As for the whole optical vs EVT, my personal preference is that I love the EVT. I specifically waited for an EVT(I was waiting and wondering BEFORE the first interchangeable lens EVT's were released) camera that met my needs because I didn't want a clunky mirror that flips in and out of place while taking a photo and I prefer the what you see is what you get. Of course, it's all a compromise and the biggest advantage of a real DSLR in my opinion is that it is a little more friendly for manual focus but given the readers question, I doubt that this will be a common use case.
Also, a good mirrorless camera(GH2) will beat a DSLR for video. This is because when recording video, the DSLR can't use it's phase detect auto-focus system so it's severely hamstrung, it has to use contrast based focus like the mirrorless.... only the current generation of mirrorless cameras are much much better at doing contrast detect focus because their manufactures have invested a lot into this.
True enough, fatigue is definatly an issue for farmers. When they want to soe they will do it 24/7 (GPS navigation makes it easyer for them to work at night of course, oh and for spraying there is less evaporation when spraying at night). As somebody else hinted at above, you do not see many animals get near these tractors once they start up. The only ones that do hang around are farm dogs.
And as for Kangaroos, out on the farms they are a pest like rodents. Okay the numbers of big reds and so forth may not be huge. But the number of eastern grey Kangaroos keeps increasing. They cause more havock to crops than most things.
The driver is still required to turn the tractor at the end of each run. After this the driver hits the engage button and the system takes over to steer the tractor to about 2cm accuracy. The driver is responsible for collision detection.
In the end the driver has reduced fatigue due to not having to make small steering corrections along a run and he can focus more on what his implement at the back is doing, i.e. is it the right height etc.
As the article says, there are huge benifits to always driving on the same track. In addition to what the article says, the piece of dirt that you are driving along does get compacted because you always drive down the same piece, this means that it becomes more road-like which significantly reduces diesel usage and tracktor wear and tear. This makes the technology even more enviromentally friendly.
