Really brief (literally) comparison of 5 Zeiss 8 power bino.
I displayed them by length
FL 8x32 / SFL 8x30 / CHD 8x32 / SFL 8x40 / HT 8x42
(only FL has the blue shield on the right side of the tube)
stated weight
SFL 30mm : 460g
TFL 32mm : 560g
CHD 32mm : 630g
SFL 40mm : 640g
HT 42mm : 830g
CHD 8x32
FL 8x32
SFL 8x30
SFL 8x40
HT 8x42
CHD 8x32

SFL 8x40
HT 8x42
CHD 8x32
FL 8x32
SFL 8x30
SFL 8x40
HT 8x42
Brightness
CHD < FL < SFL30 < SFL40 << HT42
HT deserve one more '<'
Real Field of View
HT42 < SFL 40 < FL < SFL 30 < CHD
CHD 8x32 doesn't have 8 degree fov as stated. it offer bigger FOV approx 8.2~8.3
Apparent Field of View
HT42 < FL 32 < SFL 40 < SFL 30 < CHD
FL and HT has significantly small magnification then other.
Central sharpness
CHD < SFL30 < FL < HT < SFL40
Edge sharpness
HT < FL << CHD < SFL40 < SFL30
approx
73% < 78% < 83% < 85% < 87%
Color fidelity
CHD < FL < HT < SFL40 < SFL30
all of the bino's color biased to green side.
CHD and FL is bit yellower making the bino little mintish.
SFL 30 have bit better color fidelity (more red) compared to SFL 40
Chromatic abberation
CHD < HT < SFL30 < SFL40 < FL
Distortion
HT < FL < CHD < SFL30 < SFL40
+ I have made more closer comparison between
CHD 8x42 / SFL 8x40 / SF 8x42
just put a more briefer result
Brightness
CHD < SFL < SF
FOV
CHD < SFL < SF
Central sharpness
SF < CHD < SFL
Edge sharpness
CHD < SFL < SF
Color fidelity
SF < CHD < SFL
Chromatic abberation
CHD < SFL < SF
Center
CHD / SFL / SF
Edge
(though SF shows highest CA at edge)
Distortion
SF < SFL < CHD
Among the 7 binos SF 8x42 is the least sharpness and have strongest CA at the edge.
but FOV, edge sharpness, color satuation, glare suppression and ergonomics is the best between the comparison
The bino I prefer best in this group is HT 8x42 followed by SFL 8x30
