My personal guess is that we aren't seeing a "chase" but rather a maturing market. One of the strategies companies use in a maturing market is to start chasing smaller and smaller niches in an attempt to get as much revenue as they can out of the market. I think we are seeing a number of the manufacturers do this.Originally Posted by Busted Knuckles
So, I would say that Canon is simply chasing market niches, not necessarily "resolution." The difference is that I expect most camera bodies to stay in the 20-30 MP range with one or two entries in the high MP range rather than all bodies headed toward the high MP range.
BTW, case in point in chasing small niches...the Nikon DF.....I am not even sure what niche that is chasing...the hipster market????
So, my quick generally recollection: aliasing/moire happens when a pattern (line, etc) is smaller than can be rendered by a sensor. So the sensor records the pattern in one pixel, but not the next, etc. Then, image processor trys to make sense of a partial pattern and chaos ensues.
At least too things come into play:
- the size of an image in how it is rendered onto a sensor. In the case of APS-C, it has a smaller image circle so the same sized pattern is displayed as smaller on an APS-C sensor when compared to how it is displayed on a FF sensor.
- Pixel size/density of the sensor. It otherwords, how fine of detail can a sensor resolve from the image that is projected onto it.
So, if we were to compare two cameras that have the same pixel size/density, say the 7D II and 5DS (r), more patterns will potentially result in aliasing/moire with the 7DII because of the smaller image circle with APS-C sensors.
Its early, but that makes sense to me.
So, is it possible, sure, but I think there is a reason why we are seeing FF sensors have the AA filter minimized/removed before APS-C.
