Mobius Maxi F1.5 2.7k

[Dashmellow]

yeah would need to know what value they are, larger values aren't necessarily an advantage though, you have more reserve power but they take longer to charge which can be a problem with the boot process

I don't imagine having too much reserve power in the Mobius super-cap modules presents too much of a problem.

it wouldn't need much reserve capacity at all to function correctly, 2 x 3.3F caps would be more than enough, they may have gone with 4 x 1F caps if space was an issue but I wouldn't think it's the tight for space

I don't know about you, but those of us who actually use Mobius cameras in our vehicles full time really appreciate the reserve capacity because it maintains the date and time that much longer.

there's a point where having extra reserve capacity becomes a problem for the startup process, 2 x 3.3F should still provide for around 10 days of time/date retention, I would think that should be enough for many people, go with bigger caps and you can start having reliability issues with startup, pretty sure most would go for reliable operation as the main priority

Let's see what Mobius decides to provide.

Can the internal power supply handle charging a 'Large' capacitor?
If the voltage has drained then inrush current will appear like a shorted out battery.
Bigger isn't always better.
Maybe it's not a problem with the circuitry.

Anyway, the Maxi has fantastic battery life as it is.

First look at the Maxi A and Maxi B lenses, vs Mobius 1 Lens C2

There is little practical difference in Field of View between the two Maxi lenses, despite the different values quoted:
Lens A 135deg / Lens B 150deg (diagonal)
Mobius 1 Lens C2 135deg (horizontal)

There is however a noticeable difference in distortion, with Lens A giving a much less distorted image than Lens B. In terms of distortion, Maxi A is similar to C2 on the Mobius 1.

At low speed (30mph) in good light, both Maxi A and B give similar results - slightly better than the M1.

At higher speed (60mph) driving through the trees, the Mobius 1 captures the number plate but has lots of dark shadow areas and blocky detail.

The Maxi with Lens A delivers better exposure with more detail in some areas, but the slower aperture means a longer exposure resulting in losing the number plate to motion blur. There is also a green lens flare at the top right which I noticed when the bright sun came into view.

The faster F1.5 aperture of the Maxi Lens B gives the best result. A sharp image with good exposure.

Thanks ....a good report.

Interesting results. Lens A is definitely the best for distortion. One of the things I'm not so keen on with the A and B lenses is the colour rendition. The camera settings here might also have a part, however, this looks more than just saturation. To me it looks like there is a cyan colour cast as the white's have a blueish tint and the overall picture doesn't look as clean as with the C lens. The saturation of the green can also be enhanced by cyan. I suspect a mixture of greater saturation in the maxi plus some leanings towards cyan in the colour balance, either in camera or in the lens coating.

Would be interesting to see a Tree Eye Wide Prime lens for comparison given the recent success with the zoom lens.

Myself and others have previously commented on the cyan to green colour cast. Hopefully this is something that can be improved by firmware updates.

I shot these comparisons using default image adjustment parameters, whereas for normal use I prefer saturation set at -1.

I don't have any Treeye wide prime lenses to try, only 6mm and longer. I have considered putting the f1.4 2.8-12mm lens on the Maxi.

I'm sure it could, I think a lot depends on who they listen to though

Absolutely fantastic post tony.

Thanks it's interesting really. Because we can see in the first images lens a clearly seems to be the better choice, but later on lens b clearly seems to be the better choice.

Tbh I think being able to pick up a moving vehicles registration is imperative.

Kind regards

You the man Tony!!

Thanks for the effort, I wanted to do the same, but I don't have the time right now, and as soon as I have a Maxi, I'm putting in a F1.2 lens, might be interesting.

I had a go at working out the colour imbalance. Proved much tougher than expected. I stand corrected on the cyan though. As some of you identified, far more green. That said the balance is far more complex than I could ever have imagined. I didn't even include the shadow adjustments in the screenshot to keep it compact, although at least one did have a cyan boost along with blue. There were about 10 different adjustments to colours, balance, vibrance, brightness etc to get this far.

Here's the closest I could get to turning C into A without spending stupid amounts of time on it (original C on the left, A on the right):

The yellow / blue in the 1st and 2nd one appear to almost cancel each other out. Looks as if the correct adjustment there might have been a slight yellow boost. However, what's on screen is how it unfolded as I played around.

The balance is pretty extreme though. Look at the amount of red and green added. Admittedly in the C picture there's too much red, but I didn't have much success backing this off without affecting the other colours. I did apply Vibrance which would also be a factor here over and above the red.

Recording the correct color may be more important as you think, in a hit and run where you don't see the offenders face, the owner of the car in question may argue in court that "this is not my car, yes the plates show my number, but they must be stolen or duplicated, and put on another car of the same model, but other color....".

Probably unlikely in some respects because if the police were involved if it's a hit and run, they'd be able to check for other things such as damage (by going to the owner's house), and paint transference (all paint batches are forensically unique). That said, in a case where the police weren't involved and the other driver gave false details, then if the cars finished in a position where the other drivers face couldn't be seen whilst exchanging details, it could well be a problem as all you'd have to go on from the video would be the plate, car type and colour. In those latter circumstances, I think you have a point where the colour shift is so great as to turn a car of one colour into another.

I am always trying to get people out in front of my camera when i am in a confrontational mode, but for now all i have captured are my own back and my own screaming,,,,, which tend to scare people off.
Its mostly road pigs throwing litter from their cars i want to get physical with, only a few times have a wanted to exit my car to go to another car to verify there are a seeing eye dog in it, or a drooling retard.

But in general with my car its not hard to get people on camera

Plastic 18mm M12 lens module barrels are fairly easy to find. In metal as an aftermarket product they seem as rare as unicorns.

Grub screws like the ones that come on the Mobius are available at any decent hardware store or online. You can then buy the appropriate size drill bit and install your own set screw in a lens holder.

The simplest thing to do to secure a focused lens in place is just use a tiny dab of UV cement.

You've told me this before, however I would much rather have an all metal one with lens lock screw built in with enough treading to ensure keeping it tight. The problem with plastic is it is relatively to thin to drill and tap a hole in it that has any holding reliability whatsoever. There are ways to do it, like permanently gluing a thicker piece of plastic (whatever) to the barrel without any chance of it interfering with the female section of the mount and drilling/tapping a whole through both, but that is a PITA when it has to be done.

The simplest thing would be for Mobius executives to list the metal barrels (alone) for sale, so those that wish to do it could, without going to a lot of trouble. Perhaps Tony could relay this message to those executives, they would have everything to gain and nothing to loose.

Lola said. Something is messed up with the posting process!!!!!!!!!!!!!!!!
Sorry but I have to disagree, lens B is better in all instances, the only really bad thing I see is in Driving 1 something seemed to go wrong in both A& B with B still being better then A. The girl standing on the left was very dark and grainy in A, In B she was somewhat lighter color in her jeans but it was not as grainy but the frame still seemed out of place overall, almost like the cameras/something moved.

All in all though, the B lens is putting the Alens to shame as it should with it being f1.5. I hate to say it but I don't think either lens is that good really, shooting at night I expected to see a larger difference with the B lens because of it's f value. I think it will really get interesting when one of the varifocal lenses or the 4mm star burst lens that everyone seemed to like is put on the Maxi, that will put some arguments to rest I think!
However currently TonyM has the job of reviewing the Maxi as people will purchase it and he is really doing a great job of it. Just my opinions.
