  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Ikonoscope A-cam dII

Typos begone

Typos begone

Thanks Hunter! The errors have been corrected.

I read one post somewhere that stated the monitor mounted in the side of the A-Cam dII is actually OLED and not LCD...can anyone confirm or deny that? It'd also be nice to know the display size.

Display size or resolution? The resolution for both the EVF and preview screen is 640x480, which is a little disappointing (especially after you've bought / tried an EX1), but maybe the DII will come with peaking and / or expanded focus capabilities?... I'd sure hope so, anyway.

M101.
 
Fantastic. For the price of a EX3, you can get 2/3" sensor, 35mm lens and DOF and large storage.
All this in a package smaller than Ex3. I am ordering one today.
 
I'm also getting one, but at the moment all my $$$$ are in my red camera order :) and if I have to get just one of then, it'll be the RED ONE.
 
I've been following this thread since the announcement of the Dii and I've been enjoying every single post. Thanks a lot everyone for all this valuable information.

I have a question: With which mount will my Nikon Zeiss prime work on this camera? If any, then what adapter will make them work? I'm a bit confused and this whole 16mm thing goes way beyond my knowledge of M2+SLR Lens=Nice DOF ... and that's the last thing I need to figure out before jumping the shark and ordering one!


Thanks!

Dan-

Right now they only support Leica, PL, C-mount and IMS (according to their FAQ). They might release a Nikon mount or surely some 3rd party will. You might be out of luck at this point-but orders made now aren't scheduled to ship until February so a lot could change then (and probably will) and they could announce more accessories/support before then (and probably will).
 
IMS is an Interchangeable mount system from P&S technic. It allows the mount ot be adapted to all kinds of motion picture lenses Go to their site and they list all the mount possibilities
 
It's quite easy actually. It shoots uncompressed RAW which means we'll have more info behind the image to manipulate with. Now RED has a beautiful compression but it is quite noticeable when shooting 2K, especially in low light.

The guys have managed to do a S16 cam that is the rolls royce of action cams so why wouldn't this have the same ergonomics and robustness? If it does this will be my little action cam. Although this one is an actual production cam as well, being silent and all.

Downside is big data files.


Now all this depends of course on the image but knowing the guys they will not promise things for nothing.
 
I understand it has a single CCD.

It would be interesting to see colour separation, aliasing, vertical smear, dynamic range, how it handles overexposure and many other potential weaknesses of such design.

My thinking is that, whilst they capture uncompressed signal, they may not be able to produce the optimum outcome if the sensor itself does not produce sharp and high MTF signal to start with. Generally, light compression is not degrading image quality in obvious ways, RedCode is the best example, but sensor quality is much more critical component. Even uncompressed, the end result may be inferior to that of many popular 3 x CCD prism or CMOS camcorders recording compressed and processed signal. In other words, it may not be an optimal design, despite lossless recording.

It would be good to see some image samples, specially charts: resolution charts, colour charts, and some real-life images. Have they produced any samples to look at?
 
In a week or two they are going to have a workshop, and I'll be there and do as much testing as they allow me to :) The potentials for this small cam are good, just see what happens during real life tests.

Photoshop and After Effects seems to have full support for the DNG files (Adobe RAW). So I guess a workflow now is to import them into After Effects and batch render out Pro res Quick time files. If you'r shooting for film transfer, I guess 16 or 32 bit float TIFF, or OpenEXR are good formats.
 
Im not sure 100%, but this seems to be the kodak CCD:

"The vertical overflow drain structure provides antiblooming protection and enables electronic shuttering for precise exposure control. Other features include low dark current, negligible lag and low smear."

I am just borrowing this information from another forum, it could be complely in-accurate but it does look exactly like the sensor in the mock-up at IBC.
 
Tar and Fence: Thanks a lot for the info! You've just solve my biggest issue regarding the Dii!

weirdcrew: Regarding the Redcode compression... Boy do I know what you mean. In 2k, Redcode 28 with low light, the grain is awful. Blue channel is all messed up. Anyway, I can't wait to see some uncompressed frames that the Dii will spit out!
 
I find the grain in 2k quite pleasing and organic in 2k although I prefer Redcode 36.

However blue channel is weak on all ccd and cmos cameras and even film. It's just the nature of the beast.
 
hehe i know, but in Redcode 28 the blue channel looks more like a cheap fractal texture than actual grain. At least in my case! That was my mistake though, i should've used redcode 36.... Next time!
