-- hide signature --

Calculated Angular Resolution [Approx 9% MTF]
-------------------------------------(microradians)

---------------------------- Lens ----- Sensor ---------- Total
SX30: --------------------24.1--------19.0------------30.7 (measured 30)
SX40:---------------------24.1--------20.5------------31.6
SX50:---------------------18.9--------14.3------------23.7
FZ200:--------------------16.2--------28.6------------32.8

Notes:
----------Smaller angle means better resolution.

----------Calculations are for distant objects at full optical zoom
----------and widest aperture (tested as best for SX30).

----------SX50 calculations are based on:
------------------ f = 215 mm (1200 mm equivalent)
-------------------f/6.5
-------------------4,000 horizontal pixels; 6.17 mm sensor width

Formulas for calculations are given in:
