The Sony sensor is very good, but if you exposure the Canon optimally the difference is generally academic in the vast majority of circumstances. However if you have no understanding of exposure the exmor is better.However, filter manufacturers sell loads of 1-3 stop GND filters so a couple more stops of dynamic range is useful to a lot people as well, even people who understand exposure, or should I say, especially to people who understand exposure.
Which is fine for photographs with a split horizon, What of trees extending in the darker area of the graduated portion of the frame? I used to be a big GND filter user, but I prefer using a combination of shots to balance exposures across a frame. I don't like GND's because I can usually see the GND graduation in the frame which points to a poor methodology to control the contrast in the first place.
Those people will know that by using a 1-3 stop GND you are able to get more light to the non ND part of the frame, which, depending upon what you are shooting, results in improved data from dark areas whether you are using a 12 or 14 DR capable camera. So you probably have as many Sonikon photographers buying them as Canon.
I agree with you; I don't use GND filters at all since digital has come of age - ie for about the last ten years.
100 seemed to me to be suggesting that the continued production of GND filters is to support those poor souls who still use Canon for landscape photography.
Most of my panoramics are shot in the way you describe, but often I don't need to do this. There is more latitude in these modern Canon sensors than some people give them credit for. Here's a shot out of a window at Bolton Castle in the English Yorkshire Dales, where Mary Queen of Scots was imprisoned by Elizabeth I. It's actually taken from a 'garderobe' ( toilet) L shaped passage, and the only light coming in is from this window. It was taken at mid day with the sun out.
I've shown the original jpeg from RAW with the jpeg picture style applied. Then I've shown the finished picture, and finally for those that like absurdity I've lightened the shadows and brought the sky down to silly levels. Anything blown ? No. FPN ? Only in the few areas where the sensor has recorded zero light, and even then it's not bad.
And this was taken on the 'old' 5DII which is nothing like as good as the 6D in it's latitude and data manipulation.
