XZ-1 Tips
page 13 of 29
Depth Of Field (DOF) xz-1 f/5.6 , full tele, 40' to infinity. At wide angle, you don't even
have to think about it... 6' focus distance will put EVERYTHING in focus.
XZ-1 DOF circle of confusion = .00686
Camera sensor sizes-- 1/2.3 = 6.16mm x4.62mm ... 1/1.6 = 8x6 ... 4/3 = 18x13.5 ... APS-
C = 24x16 ... 35mm = 36x24. Prints: 8 x 10 inch (203 x 254 mm) or 32x enlargement
from XZ-1 compared to 10.6x from APS-C.
Sensor 'bokeh' blured background -- the XZ-1's 24mm -112mm equiv. lens delivers the
same 'bokeh' that you get from a full-frame camera with a 24mm - 112mm lens at f/8.5 -
f/11. Some, but not much. Best, for normal images -- at f/1.8 in full tele 112 equiv. -- to
focus on something nearby with some separation from the background. SuperMacro is
even better, where your subject is from 1/2" to 1' away, and the background will be quite
blurry... but remember, you can't use flash in SuperMacro mode.
Panning
Here's my 'formula', for small-sensor camera owners:
1. Get away from wide-angle! Instead, use the most telephoto your camera has, like my
XZ-1's 112mm equivalent tele zoom.
2. Try to position yourself so that the panning subject, like a moving car, fills as much of
the zoomed frame -- the field-of-view -- as possible.
3. Think ahead. Pre-focus on a spot at about the same distance as the subject will be...
before it gets there.
4. Shutter speed -- use S -- shutter-priority mode. Experiment to find the slowest-possible
shutter speed that still gives you a sharp subject as you swing the camera to follow the
subject... like 1/30.
