They could just license exFat which supports larger files and is a faster file system for Reading / Writing than FAT32.

I believe that the “Ikonoskop A-Cam DLL” shoots raw DMG files. They have focused on increasing the pipeline to the storage card that much, instead of going through compression algorithms. The cam is not out yet, but some people are shooting on protoypes. I probably works, but I suspect it will end up like vapurware eventually, because they have really let down their customers by always moving the release date, and eventually just shutting up and not making any press statements at all. But we´ll see.

That is precisely what I am arguing against. Having one camera with lots of gizmos and another without those gizmos is not necessarily going to make the “basic” camera cheaper; it could well be more expensive, as it would be a niche product.

On the other hand, there are many differentiations between models in the range, but usually only when it comes to things that actually affect the price: different bodies, different viewfinders, different sensors, different AF modules, different shutters, etc. Your objections are mostly targeted at things that are unlikely to change the price. The same DIGIC 4 processor and firmware is stuffed into almost every model. Once one model has the related gizmos, it costs almost nothing to add them to the others, particularly as it should increase sales.

You also claim that the features “do cost extra”. However the MSRP for the current generation of cameras is lower than for the previous generation. Any suggestion that they could be even cheaper would be pure speculation.

Canon, it’s really not so difficult. Just output uncompressed 1920x1080p via the HDMI port, or add an HD-SDI port. We’ll connect that to a Convergent Designs nanoFlash box for the lightest possible compression (up to 280 Mbps I-frame only 4:2:2), which you can’t do in the DSLR.

See http://convergent-design.com for what the video guys use to record at higher quality than the native formats of their cameras. (No, I don’t work for them.)

Could the 1ds mkIV be coming out with a high speed function? Perhaps 120fps 1080p video and 240fps 720p?

Thanks for clearing that up. I do notice some compression on Vimeo, but I always assumed people were editing in the wrong format, and not properly converting first (Apple lossless?). So it has to do with the compression in camera. Well, I am very excited for this RAW video that comes out. And the ensuing size/speed race for cards capable of holding this these raw files.

However, offering raw seems like another step towards film makers, which is great. I just hope that photographers are getting some bumps in resolution and noise handling and other bits to make this a very worthwhile camera.

Or not enough if you’re waiting for the 3D

There was an interview at the introduction of the 5DII,
where the Canon rep said the 5D to 5DII cycle was longer than they planned, that future cycles would be more typical.

With Nikon & Sony pushing FF Canon would be stupid to leave the 5DII as is for 3 years.

RED does NOT normally shoot RAW video, but (mostly) 6x wavelet compressed.

Just my 1920 cents :)

Full HD video = 1920*1080

Say you only use CFA pixels (cheating), 14 bits per pixel.

1920*1088*14 = 29 245 440 bits per frame
29245440/8 = 3 655 680 bytes per frame
3655680 * 30 fps = 109 670 400 bytes per second

About 100 MB/sec for uncompressed Full-HD video at 14 bpp.
Add the lamest lossless compression, say 50%, and that’s “only” 50 MB/sec.

And there you go ! Your 32 GB flash will store 10 mins of 14-bits raw goodness ;)

Well said Iolicht! The moiré problem is the only reason why I haven’t committed on an upgrade, hoping the next model (maybe the s?) will fix this problem!
