Viewfinder Coverage

This test measures which part of the frame taken by sensor is really covered by the viewfinder. Test is performed shooting a 240x160 mm panel and then measuring the real viewfinder coverage on the resulting shot.

Lens used: 17-35 mm
Focal distance: 35 mm
Angular error: 0.8°

	+5 mm top
+9 mm left		+4 mm right
	bottom +3 mm

Lens distortion

This test measure lens distortion at various focal lengths. Test is performed shooting a checked target and measuring image's distortion degree in percentage, placing it on an ideal rectangle.

17 mm test Barrel distortion +1.2%

35 mm distortion Zero distortion +0.05

minimum distance from lens: 153 mm focal lenght: 35 mm coverage: 124x82 mm px/mm: 24 distortion: zero corner sharpness: good corner purple fringing: average

Vignetting

This test shows image's vignetting at minimum focal lengths.

shot in wide angle: 17 mm

Shows contours of the normalized luminance of the image file.

Flash

This test measures flash light uniformity at various focal lengths.

wide

shot in maximum wide: 17 mm
