Whilst technically May Day is the 1st of May, in the UK the May Day bank holiday is always on the first Monday in May so we can never loose it to a SundayKoepi wrote:You're very lucky in the UK! In Germany such holidays are simply lost when they are on a Sunday. Never would have imagined that looking at the system Thatcher built/stood for otherwise.
That's what I thought at first, and some units may indeed be bad. But I would call my result from one test at 30 cm at least adequate http://bealecorner.org/best/RPi/PiCamV2-test7.jpg and I feel the one at 40 cm from hystrix is really quite good (at least, for the center area where the test pattern is): https://www.dropbox.com/s/dlav27jry1dwze5/new_cam4.jpg Yes, the strong moire color pattern on fine line patterns is an image defect, but it would not be present if the lens had poor resolving power. For those specific units, the problem seems to be simply the focus setting is in the macro range, and not at infinity.Koepi wrote: The lens is bad, plain and simple.
I'm not as sure. I agree there is a "soft-focus" effect on the fine print example, but that high-contrast target on uniform white background makes this effect more apparent than the backyard scene, so the v2.1 board with v1.3 lens may have it as well. I would need both configurations recording the same target to compare apples-to-apples. The soft focus effect can be modelled as a sum of a sharp and defocused image, and can be reduced by post-processing steps (eg. unsharp mask). I believe noise reduction is also being done which can have similar effects on fine detail. All these sensor systems do that type of processing, the difference is how much (a tuning parameter, and personal judgement of whoever does the tuning). Anyway at this point it's clear there's a problem to address and I doubt I'll spend more time on experiments. I will wait for further announcements.Koepi wrote:When looking at my full resolution images, there are some spots with 'ok' focus. Close to the center, between 10 and more than 50m away (looking at the fine branches of the trees).
Looking at your fine print photo I see the same 'wash out' effect on the letters, that is also not sharp. Its good enough so you can read it, but compare that to a photograph made with your smartphone.
Also, when you swapped lenses you immediately got more-than-decent results. That makes me quite sure that the lens is unsuitable and faulty.
Uffda. Are you recommending the community hold-off on purchasing the V2 camera until things get sorted out...jbeale wrote:Anyway at this point it's clear there's a problem to address and I doubt I'll spend more time on experiments. I will wait for further announcements.
Thanks. heh, I have read the entire thread; was all set to purchase the new camera but may wait now.jbeale wrote:viewtopic.php?f=43&t=146579#p966456
I'm not making "recommendations for the community." I do presume at some point the above-referenced ongoing investigations will reach some conclusion.
That makes perfect sense to me, for a RPi camera. Problem is (I think) the RPi sort of application did not exist until very recently; the volume* use cases the manufacturers designed for was mobile devices, and maybe car backup and dash cams. Those were supposed to be simple, sealed, no-adjustment consumer items. So they only provided for loose fitting lenses, one-time factory-set which need glue to keep them in place. All this just my personal guess. If you did make the existing lens a tight-fit but adjustable, you would likely still need a tool for the adjustment, as the lens is so small (6mm size).MarkHaysHarris777 wrote:I really think the lens should be adjustable; honestly. The lens should not be fixed (not glued) ; it should be tight (snug) and the user should set it according to macro or infinite (whatever).
Yes. Maybe the foundation needs to design their own rather than vend it out...jbeale wrote:(main use case)... Those were supposed to be simple, sealed, no-adjustment consumer items.

Yes, precisely... just tinier.Gavinmc42 wrote:Rotating optics like this?
Since you suggested that, I tried that. My phone is a Samsung GT-I8190 with only 5 MP camera.

Any official news before I return 4 of the new V2 cameras i purchased?6by9 wrote:Investigations are ongoing.
