Both the Mobius Maxi and GitUp F1 are matchbox-sized action cameras which have modes and features that make them suitable for dashcam use.

Disclaimer:
I received the F1 from GitUp in November 2017 for testing
I received the Maxi from Mobius in January 2018 for testing

Dimensions
Maxi - 71 x 35 x 18mm
F1 - 82 x 41 x 23mm

Power
Maxi - Battery or capacitor
F1 - Battery. Capacitor option being developed.

Controls
Maxi - Power, mode & shutter buttons
F1 - Power, mode & shutter buttons + OLED display

Interface
Maxi - mSetup desktop application for setup. WiFi apps being developed. PC webcam mode.
F1 - WiFi app for live view and setup. Bluetooth for remote control.

Lens
Maxi - Lens A (~135deg FOV, F2.8) & Lens B (~130deg FOV, F1.5)
F1 - 160deg F2.8 & 90deg F2.5 (NOTE: I do not have the 90deg lens to test). Faster lens believed to be in development.
Both cameras use M12x0.5 mounts and can accept a wide variety of third-party lenses

Sensor
Maxi - 1/3", specification not stated, max recorded image 2704x1524
F1 - 1/2.5" Sony Exmor IMX317, max recorded image 3840x2160

Mounts
Not supplied as standard. Both cameras have slide-in cradles with a removable 1/4" tripod socket, which allow them to be mounted upside-down from a windscreen mount.

Firmware
Both cameras have received firmware updates since being released for sale, typically addressing Image Quality issues and adding some functionality. FW development is ongoing with both cameras.
On the F1 I am currently running MOD1.5+Sharp TEST firmware developed by @Falsificator
On the Maxi I am running FW v2.04, which for the purpose of this comparison is identical to the current release v1.90

well it is fair to test with factory firmware, but it would be a big a shame to ignore the good work of @Falsificator (y)

Day Video 1

As expected, both cameras perform well with a good amount of sunlight. The wider FOV of the F1 is useful at junctions to pick up action in adjacent lanes. The F1 video looks more natural than the Maxi and has a wider exposure range. The Maxi video looks over-sharpened by comparison.

F1 - 4k 30fps 100Mbps / Medium sharpness / EV 0
Maxi - 2.7k 30fps 60Mbps / Medium sharpness / EV 0

Day Video 3

Driving at higher speed along country roads, the F1 starts to show motion blur even with bright sunlight, perhaps due to the relatively slow F2.8 aperture lens. Whereas the high-gain high-sharpening approach of the Maxi allows much faster exposures which result in far less motion blur. The high bitrate of both cameras retains detail where other cameras struggle with so many trees and shadows.

YouTube is not an ideal platform to judge the image quality of these videos due to the high bitrate required to display these scenes effectively. The sample frames below are better for assessing the video quality.

F1 - 4k 30fps 157Mbps
Maxi - 2.7k 30fps 60Mbps

On another car passing at speed, motion blur is much more evident in the F1 than the Maxi, to the extent that the number plate is blurred beyond recognition whilst the Maxi remains fairly sharp. In this example I have used the best detail frame from each camera, so the passing car in the Maxi frame is closer than on the F1. The F1 became even more blurred as the other car came closer.





I hope to test the F1 again soon with a much faster lens which should help to reduce some of the motion blur observed during bright sunlight.

Night Video 2

Driving in the city at night, again the Maxi shows a far brighter overall scene with less blur that is much better at capturing pedestrians and cyclists as well as other cars. The F1 video has good detail and very low noise, but fails to capture enough light in poorly lit areas.

F1 - 4k 30fps 100Mbps
Maxi - 2.7k 30fps 60Mbps

What kind of metering was / are you using on that daytime blurred plate on the oncoming car ? seem strange the F1 would not do better in those conditions.

F1 = Centre-weighted metering
Maxi = Multi-spot metering

Thanks for putting together this nice comparison TonyM,
if you had used the F1 90 degree version cam (compared to the 160 degrees F1 that you used), how different would it perform with the sharpness quality and motion blur seen in the review? Would the 90 degrees F1 be sharper and less motion blur than the 160 degrees F1?

Would the F1 90 degrees "Zoom in" closer the then the 160 degrees cam?
thanks

The 90deg lens is F2.5, rather than the F2.8 aperture of the 160deg lens, so that should shorten exposure times a little.

The 90deg lens will give a zoomed in view, similar to the 4mm lens I tried here https://dashcamtalk.com/forum/threads/gitup-f1-4k-with-100°-f2-0-lens.33322/

Motion blur on passing vehicles should appear less obvious with a 90deg lens, since the other cars are moving more towards or away from the camera, whereas with the 160deg wide angle view close up cars are passing more across the view. On the other hand, any objects passing across the view will move further across the more zoomed in FOV of the 90deg lens.

For everyday use with a standalone camera, I think 90deg is too close.

Why different metering in a comparison test?

Edit: great work though, VERY interesting

I usually leave my Maxi on multi spot as that's the default setting. The F1 does not have multi spot.

I can re-test with both of them on centre weighted metering. Based on my general experience with both cameras, I don't think that will make much difference.
