o.o I can do it... I can turn this lens into a taking lens combo with the LA7200 and create an anamorphic lens combo.
00:22
Rebelj12a
70mm but still
00:23
Rebelj12a
actually I may be able to adjust that down to 50 based on the lensing elements inside.
00:23

off to bed now ... have a good one everyone!

Hi, an idea: these guys seem to be fantics of making lens mount adapters: http://www.solidcamera.com/#!lens-mounts/c207j E.g. they make smth which plugs into a camera and on the other has got PL mount. Their thingies also have a way to be attached to rails. The resulting contraption is sold $500-$700. They also produce 0.025mm and 0.08mm shims.
14:19
__anton__
Just wondering if they could be asked to produce lens mounts for Axiom - if things make sense money wise
14:19
__anton__
Looking at the photos it seems they got some experience
14:21
__anton__
http://lesbosher.co.uk/ looks a bit expensive for the task though it doesn't hurt asking for a quote either
15:01
Bertl_oO
yes, two component/modular lens adapters are manufactured by some companies
15:02
Bertl_oO
we had a talk with P+S Technik, a German company
15:03
Bertl_oO
but yes, feel free to ask them if they would be interested in an AXIOM specific base mount
15:03
Bertl_oO
what we would need is the interface to their mount adapters
15:03
Bertl_oO
and the parameters to get the focal length right

hello
17:06
intracube
is there any good data for how sensitive the CMV12000 is in global/rolling modes + with 2x2 binning etc?
17:07
intracube
I saw that MagicLantern have started to do some tests on the sensors
17:08
intracube
I think I read that the Aptina sensor is nearly as good as the A7s
17:08
intracube
for low-light

intracube: the CMV12000 is not rolling/global switchable
17:46
intracube
se6astian: aah, ok.
17:46
intracube
I got it confused with the Truesense
17:49
intracube
and I got Truesense confused with Aptina. ho-hum

hi!
21:08
surami
there will be gigabit ethernet ports on the beta?
21:08
se6astian
one yes
21:09
surami
but i has only 125 MB bandwith
21:09
surami
i have something in my mind again
21:09
surami
:)
21:09
surami
to store data
21:10
surami
but i don't know if it would work or not
21:10
surami
if MLV will be the video container
21:10
surami
maybe it could be splitted
21:11
surami
and send the information out to 3 ethernet ports
21:11
surami
lets count with around 300 MB/s alltogether
21:12
surami
375 would be to close to the border
21:12
surami
so if the file could be splitted
21:13
surami
then this PC Engines apu system board
21:13
surami
could get the dataflow through 3 ethernet ports
21:13
surami
http://www.pcengines.ch/apu.htm
21:14
g3gg0
MLV is designed to split it on a per-frame level
21:14
surami
then store it on raid msata maybe?
21:15
surami
yes i know that
21:15
surami
but could it be splitted somehow?
21:15
g3gg0
ok :)
21:15
g3gg0
?
21:15
g3gg0
ah you mean different paths
21:15
g3gg0
i dont know, but i am confident that bertl is working hard on evaluating possibilites
21:16
se6astian
He definitely is :)
21:16
se6astian
time for me to rest
21:16

HDMI out for RAW is not too ok or?
21:17
surami
i don't know
21:17
g3gg0
just came home. will need some rest too :) (and will enjoy my rift dk2 by watchting a movie)
21:17
g3gg0
uh, why HDMI
21:17
g3gg0
its all about LVDS interfaces
21:17
g3gg0
which connector doesnt matter
21:18
surami
well i don't understand this "chiness" stuffs :P
21:18
surami
but ok
21:19
surami
then let's Bertl to do it, he is the tech master here as i see
21:19
g3gg0
3xHDMI means 3x3xdifferential pairs to get data out of the device
21:20
g3gg0
what you have on the other side of the cable, who knows? maybe some additional fpga board that also has a multi-SATA interface. maybe. maybe not.
21:20
g3gg0
as you say. let the hardware gurus think about it
21:20
surami
yes
21:21
surami
it will be better
21:21
surami
but i'm too curios :)
21:21
g3gg0
i am sure the best solution will find its way into the beta
21:21
g3gg0
we all are
21:21
g3gg0
that said - i wish you a good night

http://www.toby.co.uk/content/catalogue/products.aspx?series=FOLC-1xx-xx-xx-Q-xx 4 row socket strips, can be 30 positions long, can be surface-mounted or through hole, have got a "low insertion force" variant, seem to be in $16-19 range

23:09
Bertl
__anton__: you are considering them as sockets?
23:10
Bertl
the problem here is, for through hole that might actually work
23:10
__anton__
hi Bertl, yeah we had this chat before right? You said you'd need a dummy sensor during reflow
23:10
Bertl
but for SMD, you have the problem that they must be aligned, yes
23:10
Bertl
ah, okay, so you know :)
23:11
__anton__
dummy sensor would just be a piece of metal with several pins
23:11
__anton__
yes because you told me :)
23:11
Bertl
yes, but not that trivial, i.e. we can't use soldered in pins, because they would get lose during reflow
23:11
__anton__
true
23:12
Bertl
that's why the peel-away are so appealing (pun intended :)
23:13
Bertl
we get the stability for the reflow and we get rid of the 'socket' part after
23:15

Bertl: maybe I'm wrong to worry about it.. but I'll let it out. Looking at this photo from Sebastian http://www.octoray.co.uk/axiom/misc/sensor-photo.jpg I can't help thinking that if the cold-plate runs between sensor PCB and the sensor it will end up only 1mm away from the mount. Will it be in any way an obstacle to trying to cool the sensor? E.g. will it not end up cooling the mount as well?
23:27
__anton__
Then the screws from the mount need to go into something. What do they go into? 1mm plastic wall? wouldn't work.. into the cold plate? but then this is another way to transfer cold to the mount
23:27
Bertl
well, first, cooling the mount might not be the worst thing, because it will indirectly keep the sensor cool from the fromt as well
23:28
__anton__
If we're speaking about using the mount to dissipate the heat from the sensor - yes it's a good rediator
23:28
Bertl
second, unless we make contact with the mount, the gap (of 1mm) between plate and mount will be a strong isolator
23:28
Bertl
i.e. be it air or some insulator between mount/plate, it can be quite efficient even with only 1mm
23:29
Bertl
that's why you want your processor to touch the heat sink and have micrometer thick heat coducting paste between
23:30
Bertl
it is really a factor of 1000 or more between air and e.g. aluminum/copper
23:30
Bertl
(regarding heat conductance)
23:32
__anton__
ah ok, thx for explaining :)
23:32
__anton__
..and then you have holes in the cold plate where the lens mount screws go into smth?
23:33
Bertl
yes, the idea is to screw the cold plate against the lens mount
23:33
Bertl
placing the sensor precisely on those four points (with or without shims)
23:33
Bertl
and also making excellent contact with the cold plate
