No zoom in RAW

[Hank]

I have tried the APS-C mode a long while ago so I can't really remember why I don't use it now. So I can't give you a clear cut answer to that.

My guess would be because APS-C mode will give you 1.5X crop where Clear Image Zoom gives you 2X, so it's the difference of having the same as a 600mm focal length vs 800mm focal length when your 400mm is at full stretch.
