Focusing with V1U
On some cameras, it is possible to:
- zoom in - focus - go wide to frame the shot as you wish, and focus stays the same Is it possible with V1U too? (I have grave doubts, but hey...) |

Of course it is possible - and often desirable. There's been one report on loosing focus when re-framing, but that was due to the "back focus" problem with that particular unit.

Piotr,
It was my camera and it wasn't the back focus. It was operator error in having the macro focus function engaged. As I stated in other posts the owner's manual shows Macro Focus ON as the default setting so users check to see if the Macro Flower icon is displayed in the viewfinder. Lee |

Lee, are you saying that with Macro Focus ON, the re-framing will lose focus?

That's interesting. What aperture are you shooting? My focus problems in Macro occurred at wide open aperture, shooting at least 1.5 meters away from the subject. If you're shooting at f 5.6 or greater then perhaps the focus is not as critical. In the last interview with focus problem I was rolling as I zoomed in to get my focus. It was very clear in playback that I got razor sharp focus on the subject's eye, and it turned soft as I framed the shot. Anyway I'll just leave the macro off unless I need it. |

Lee,
I'm trying to never go below F5.6, with tighter apertures it's really hard to tell a razor sharp focus from anything close to it. Anyway, I'm also turning the macro off, but for quite a different reason: it makes the focus ring much more precise.
