Turns out pixel shift goes up to ISO 1600. Makes sense I guess, if you're using higher ISO it's because you need to shoot fast. I guess the Canon wins for night time (specially for night wildlife it's currently the best camera you can get).
>>3818202I don't think it's so cut and dry. Some situations will favor the Canon, and other than the bulk there's no disadvantage to the bigger lenses. The pixel density is the highest in the market right now.
In terms of reach there's no beating it (for now).
Now, for landscape the Olympus wins hands-down. A bit less resolution but you can get more in focus with a brighter image.
