Pardon my ignorance but once locked in how does it rotate if needed?
It's time for you to eat humble pie my friend. I fixed it!!"If you're not willing to take the approaches being recommended to you, then nobody can help you in any way"
My opening question was " Anyone else having poor image problems with the A119 V3???"
So I was expecting a wealth of experience of instances of poor image quality, as after that is what I was asking.
I was asking for possible causes, not asking for a testing procedure as I am quite capable of devising my own testing procedures for any cause I was to investigate.
To your credit you offered the 'left field of view issue', one that I actually was aware of. Unfortunately the rest of the replies were all about the car speed being too high and light level too low, both of which I dismissed as I have pulled great images off my A119S at more than double the speed of the cars in this instance, and that the lighting was not low although people have obviously mistaken the lack of washed out highlights (due to exposure at -0.3ev) as evidence of low light while ignoring the blue sky. Ironically none of them actually knew what the car speed was, nor the light level.
So instead of offering other suggested causes of poor image, people instead for some reason wanted to insist I carry out "their prescribed testing procedure" and submit the results to them for perusal, presumably in the hope of proving my dismissal of speed and low light as being wrong and them being correct, or they would take their bat and ball..
Actually having fiddled extensively with readjusting the focus on my A119 V3, I can see yours is focussed too short. The light sensor and vents on your dash are in perfect focus at the expense of focus further away eg the car ahead of you has a soft focus.I had a Nextbase 412 and I was offered a free 422 on release to review. Having seen the specs (battery and ball joint) I declined and glad I did. I started with a A119 V2 and got a V3 shortly after release.
Never regretted it and this latest HD @ 60fps is proving superb. Sample shot in normal conditions, very sharp:
It is no longer winter, my guess is that you have far more light now and that is a significant factor.and a similar light level, probably more cloud than the previous photos.
Actually none of the above. Just poor focus adjustment from the factory. So I have adjusted the focus now, and centred the focus for about 15 metres away and the difference is chalk and cheese. Look at the new photos I have posted.
- It is winter.
- The sky has lots of thick clouds in it; there may be a little blue sky, but not in the direction of the sun.
- The shadows are hard to see - indicating low light level.
- You are driving under trees with thick leaves blocking light from the direction of the sun.
- The time is well gone midday, not sure how long the day length is there at this time of year, but light levels will be well below midday levels.
- The issue looks like motion blur.
Maybe everyone except you is wrong, but you don't have another explanation otherwise you wouldn't be asking for possible causes, so I suggest you do a quick check on some stationary footage just to check who is correct, if you are correct then given more evidence we will consider alternative causes, if everyone else is correct then you have your answer - there is motion blur when driving under evergreen trees on a day with thick clouds in the middle of winter.
Nope, the unit was just out of focus. Fixed now.It was reasonably good sunshine. Not dull by any measure.
I wasn't driving fast, about 50 kmh, and the oncoming car was slowing to turn.
The crux of the issue is, my old A119S took better photos on the right than this A119 V3. Why should my old A119S take better video clarity than my new A119 V3???
I didn't have the tools, it was out of necessity due to poor customer service from the manufacturer. I sent them the video and they claimed it was normal.OOF ( Out Of Focus ) from the factory are not something we see often, but OFF after being hit by high summer temperatures have traditionally not been uncommon, but even heat related focus shift are also much more rare nowadays.
Customers should not have to deal with focus either way, but of course if you have the tools and some DIY skill it is a easier way of getting a result VS sending your camera off to god know where you got it from.
Also why i always recommend to buy locally as that should make the RMA process simpler.
If your focus have slipped and remain there, you are good to refocus it, if you can / want to, but if your focus go out during the heat of day but are fine at night or fine in the morning before it get hot, then you probably have a lens failure and that you can only fix by replacing the whole lens.
The focus cant slip from high temperatures or bumps as the barrel is on a very fine thread and it is glued so it wont move. The glue is like hot melt glue but 1000 times tougher. The greatest difficulty is actually breaking the glue so that you can adjust it. I had to rotate the focusing barrel between 1/6 and 1/4 of a turn to get it in focus. That's a lotOOF ( Out Of Focus ) from the factory are not something we see often, but OFF after being hit by high summer temperatures have traditionally not been uncommon, but even heat related focus shift are also much more rare nowadays.

Heat related focus shift really should not be a problem as the camera tube that holds the lens is all aluminium. Any potential for permanent heat distortion would only be the circuit board and CCD that the tube bolts onto, and this appears to be quite robust.OOF ( Out Of Focus ) from the factory are not something we see often, but OFF after being hit by high summer temperatures have traditionally not been uncommon, but even heat related focus shift are also much more rare nowadays.
