All these threads about the same topic . . . and the same worries, etc etc etc etc etc
If you are with Canon, and not with Nikon, you must understadn that Canon has the tech to make sensors that are out of this world, and even lenses. . . . but the thing that bothers me is that they refuse to beat the pants off Nikon, and are instead happy to just be at par or follow in other respewcts, or to only catch up in others.
If you are with Canon, then I would stick with Canon simply because you are with a company that makes itès own manufacturing and advancements in tech. They make their own lenses and sensors, and also create machines for eye surgeons and other hospital technologies. They have the ability to make 120MP sensors, and they do not make it 3rd party. If you are witrh Canon, then you need patience . . if you are with Nikon, then you need to worry about when Canon will explode and create things not seen befoer in the stills and video sections . . . and I can tell youthat JUST NOW they are starting to go all out. Still they take thier time and agravate the masses, at times. That is all the have to think about. Sicne the photographer is the last word, stay with Canon and worry about your images: composition, artistic merits, and creating a name for yourself, not based on a few points in DR or ISO either way. . . . Keep your eye on the ball, and all this other stuff becomes less of a hassle that it really is.
