8. Postprocessing
1. Personal setup: Aperture priority with manual aperture preset; manual ISO select; single-point light measurement; manual exposure time compensation; autofocusing & manual focusing; b/w mode; jpg format; 21:9 or 2.35:1 crop; verdict: special
2. Permanent use: To protect front lens against anything unwanted (uv ultraviolet radiation / energy and matter from fumbling fingers and dust); verdict: must
3. Rare use: Not explicitly recommended by manufacturer. No big effect on wide angle as well as on magnification; anyway still pretty sharp in the center with some vignetting towards the edges; verdict: extremely special
4. Infrequent use: In some outdoor daylight situations; to modify the energy transfer function (by analogue means); verdict: interesting
5. Infrequent use: Camera display in common daylight outdoor brightness situation badly readable; viewfinder required to roughly see the image area; to see full image area, off-center viewing to the left and right is required, which is quite a poor performance of the viewer; however, a 21 mm setting gives a approx. 18 mm or an approx. 24 mm view depending on center / off-center viewing; not a precision instrument; therefore no accurate at all; significant barrel distortion; no indication of different aspect ratios, such as 21:9 or 3:2; viewfinder is not in-line with the optical axis of the camera lens, which is not a problem for long-distance / infinity-distance objects; viewfinder is a passive optical device just following plain geometrical optics without additional functions and without displaying functions of the camera; parallax is not a problem for infinite distance objects; main function: saving electrical energy! other function: less precision, more prestige; verdict: too expensive, very nice but not really useful / helpful

6. Infrequent use: With aperture 4.0 and low ISO sensitivity 100 the mechanical wobble, twist & shake, rattle & roll limit is reached pretty often even in common daylight situations; verdict: must

7. Rare use: Smooth wavelength cut-off / low pass at 715 nm / 780 nm / 830 mm wavelength. Manual focussing is required. Exposure times easily 100x larger than no-filter times. Not yet tested. To be applied to technical photography. Interesting.
