Originally posted by Mock I was under the impression your lenses were already upside-down like that.
Does the bokeh of your lenses like Helios 44M swirl in the opposite direction?
Down-under, we obtain out of focus first.
So when people usually press a shutter release button half-way down to obtain focus, we down-under do same, but the camera obtains out-of-focus.
So we point a camera on things we don't want sharp, and the lens does the rest and makes everything else sharp.
Also, all lenses for down-under wallabies must be made for LH drive too; you turn them in an opposite direction, and when you do that, it means zooming out, not zooming in.
