the problem with canon XL lenses is that they only work with power and all the controls are digital digital focus zoom and no aperture setting.... so to test out the image quality we build an canon xlmount and i used the canon xl1s to control the lens on my miniraw :D crazy but works now i need to reveres engineer the spi that comes from the camera for this prupose i have an logic analyzer nice project and the great thing about xl lenses is that it also has an 1/3" sensor and there is an canon xl 3.4-20.4 lens which would be an equivalent of 24-142,8 niceee :D

 

any of you guys has workd with lens protocols like spi?

 

cheers janosch 

some small update ;-) 

just put a smal clip together what do you guys think?

 

spread the word :D

 

cheers janosch

hey guys things work fine but still lot of work :) my 10" cap touch screen works great need to mill a case :_) and today i got my poor mans redmote http://instagram.com/p/eDChVCI8Lk/

 :D a mini keyboard with multitouch keypad works perfect!

 

cheers janosch

Followed you from the BMCuser post.  I'm so tempted to do something like this.  I found this cam:  http://www.ptgreystore.com/blackfly-23-mp-color-gige-poe

 

Which can do 1920 x 1200 at 27fps for $315 usd.  That might be a nice starter cam.  What cpu and motherboard are you using janosch? I don't need high fps, just something that would work with 2k raw/uncompressed for now.

hey there :) im using an i7 3770t cpu on an z77n-wifi gigabyte MB :-)

cheers janosch

*cough* yeah could have a little bit more action for the fact that the download is some gb ^_^

 

but in anyway it looks nice logish :-)

ARGGGGG just got my Fujinon 6,4-90 f1.4 lens i THOUGHT it was an B4 mount because the ebay dealer wrote it....

 

so my buddy and i design a mount for my MiniRAW 1 and i was excited to test it and i CANT get in in focus....so i removed my mount and hold the lens in front of the Ptgrey Flea3 and moved so it get into focus...and i need to get around< 10 mm closer.... after a long search i found this thread:

http://www.personal-view.com/talks/discussion/5862/12-inch-eng-zoom-lenses-and-mounting-solutions/p1

 

DAMN didnt know that there is an Sony 1/2" mount with an flange distance of 35.74 and compared to the B4 flange distance of 48mm it makes sense ARGGG :D

 

soo be carefull when you buy a B4 lens ;-)

 

cheers janosch

Cool! You mind sharing the 'better' proress file then maybe? Looks like a project with great potential! :)

hm if i find the file :-))) but im affraid that its to big :-/

the model said its ok so here we go :D this is just a testclip no cut just converted in davinci resolve and blackandwhite :-)

http://www.youtube.com/watch?v=--H2aBZRAgQ&feature=youtu.be

 

filmed with 120fps this time with only 8 bit and an Arriflex Carl Zeiss Distagon 8mm f2 :-) irgs that compression :-(

 

the orginial prores file is much better :D

 

cheers janosch

yeah i know that its time for some footage :D but i have only some testclips need to ask the models if its ok to show them :D

 

cheers janosch

progress :D

my prototype MFT mount works GREAT :) its like no other on the market not pressed by springs its pressed by mechanics :D

 

big thx to my machinst without him this would not be possible.

 

one pity it the the c-mount to mft adapter i got from ebay dont works :-( the problem is that i cant screw the lens far enough in :-/

 

 

but my mft to ef mount works flawless also my backfocus adjustment :-) 

 

guess my buddy and me need to machine an own c-mount to mft adapter ;-)

cheers janosch

oh how to rotate the image? :D

 

cheers janosch

Hey there :-)

 

small update :-) Just finished my "testbench" so that i can test my lockable MFT mount with adjustable backfocus :-)

 

[attachment=564:Foto.JPG]

 

 

so much work still to do but also so much fun...perhabs i can upload some testfootage :-)

 

cheers janosch

thx Andrew :-) yesterday i  tested the config and it seems to work flawless without any dropped frame :-) hm but it seems Davinci Resolve dont like 17000 DNG damn :D

sure andrew :) now everything is just on a wood board just a mess :-) but im not the guy from the bmcuser thread :) i boroughed his idea but he is more after 4k and im more after speed :-)

 

here is a picture of the setup :-)

cheers janosch

yeah looked at a lot of patents but in the end i will build my own mount ;-) my plan is to adapt arri st and later perhabs some pl mount lenses

 

today i had great success now i can record continuous in 720p 120fps 12 bit RAW HELL YEAH  ;)

 

but i didnt thought i need that much cpu power and ssd power :D

now i use and i7 3770t and an ssd RAID 0 array with 2 ssds

 

phewwwwwwwww so much trial and error :-) but also so much fun :-)

now i will start with a test metal case and plan where to put all the parts.

 

and learning some c++ and try to use the flycapture sdk to build my own gui...anybody here that is good at taking and SDK and build with this an own GUI? :D

 

cheers janosch

SOOO it seems i need to crop in Resolve  ;-) anyway another question.

 

does any of you guys have a technical drawing of the Micro Four Third mount?

 

i thought its an open standart?

 

cheers and thx

janosch

hey Julian! nice to here from you :-) unfortunately i already contacted magic lantern on facebook but the .raw from the canons is way different then the .raw from point grey...

 

and the crop thing is not that important but i HATE it when i have something i dont understand :D

 

the problem is i guess how to implement the DefaultCropOrigin code into the rawconverter hm

it would be great to see how BMCC implemented it :D

 

at the moment im at the begining of the construction of real camera body ;-) lottttt to do but lots of fun :D

cheers janosch

Hey guys :-)

as i love RAW and LOVE highspeed i thought perhaps its possible to build my own raw dng camera :-) 

i foundthis thread over at bmcuser http://bmcuser.com/showthread.php?2043-Little-raw-cam-side-project

and its roughly based on that idea :-)

 

but i went with an other camera from PointGrey its an USB 3 Flea 3 cam that can shoot up to 720p120fps.

and build a mini itx board with an intel core i3 3225 :-)

 

still lots of work to be done but at the moment i can write on an ssd 720p120fps at 8bit

and 720p96fps at 12 bit.

 

but i have a problem with my .raw to .dng conversion:

 

on the BMCC raw files there is a tag:

DefaultCropSize and DefaultCropOrigin

 

and i cant get it to work properly with my DNG converter

when i run dng_validate on an converted DNG i get always:

*** Error: Invalid DefaultCropSize ***

 

does anybody has a sample code or another idea?

 

to the some picutres of the MiniRaw1 just serach on twitter and instagram for #MiniRAW1 :-)

only pictures at the moment no footage yet :-)

cheers and thx
