How much to zoom while shooting a single row panorama image? @Itai It's not a zoom in you need for the centre images, it's a zoom out. And the panorama stitching software will indeed "undo" the zoom out, by enlarging the centre images, thus avoiding a bow-tie shaped stitched result. |

How much to zoom while shooting a single row panorama image? I only said "zoom" in my comment but I actually meant "zoom out". You want to maximise the vertical field of view of the central images compared to the edges by zooming out. |

Which parameters to lock between images for a panorama? @BartArondson if you shoot a single row panorama and stitch it with a rectilinear projection you'll end up with a bow-tie shaped image, cropping to a rectangle will reduce the size of the image. If you were to zoom slightly to shoot the middle section of the panorama then the amount of cropping required could be greatly reduced. This would require the stitching software cope with different focal lengths, and may introduce slight parallax errors for close objects as zooming will likely shift the centre of projection. |

What happens to a lens when you turn the focus ring during AF mode? The focus mechanism on the Canon 50mm f/1.4 will break, however, if you stare at it for too long:) |

When should I turn off image stabilization? @RafalZiolkowski I'm dubious about that last claim, most people leave the IS set to on the whole time, if there was say a 25% chance of this leading to IS failure then there would be tens of thousands of lenses failing and it would be all over the internet! |
