Filter that actually DOES fix moire and anti-aliasing on the 5DmkII

Any idea when this product might be released Philip? ..or anyone else. I can't seem to find a projected release date.

Cinestyle picture setting from Technicolor, now this product. The 5DII is developing into a nice little cine camera.


On a side note. I'm sure this product will cause yet another bulging vein in the forehead of Jim Jannard.

Mine has just been shipped to me so will do a full review next week. As to when they will be ready en mass. Not sure. The demand will be huge most likely.
 
now to find the money before the visa bill comes and I have to try to explain what it does and why I need it............
 
This announcement came around the same time as the first A77 samples became available, and thus I was thinking, hey, what's the point, the next generation DSLR is here... then we saw the samples for Sony's latest... Suffice it to say, they too may need to take advantage of this product. Well done inventors! There's always a better mousetrap to be built!
 
I think I will wait till October to see if the MK3 will be released. I dont want to buy it then have it not fit the Mk3 or if its even needed for the Mk3? I know I could be waiting forever..haha
 
I hear you but I'm expecting to see unicorns and a wireless redrock ff on the market before I see a mk3. Also I don't want to buy a new camera, so I jumped on this. I should get it before my Oct shoot unless pb's upcoming review trashes it for some unexpected reason-then I'd cancel the order.
 
i think its bogus personally, just softens the image. I could shoot out of focus by a foot or two and achieve the same effects basically.

nope, its not bogus. I have tested the caprock which is also an anti alias filter, THAT was the tricky one as it fits INFRONT of the lens thus making results inconsistent between lenses.
You needed different "filter power" ie; 1.0/1.5/2.0 for different focal lengths. -and the caprock softens and looses contrast. -that too is not bogus. it works for certain lens types, I use it.
-that showed the way forward.

This Mosaic filter solved it by placing the "OPLF" between the lens and sensor thus retaining the alias free image despite changing lenses (up to a degree as wide lenses tend to soften at the edges)

The resulting charts is astounding as it is now similar in characteristics to some CMOS camcorders that I have tested. -the aliasing remains in the tightest of frequencies which I would find in "traditional" cmos camcorders.

I've requested PB to allow us to see the full res charts for download as the ones posted on his blog are small compressed ones so I can confirm the line frequency that is the threshold for this filter.

How do you think an OLPF works? Of course it has to distribute the high spatial frequency over a wider range. But you are wrong if you think you can achieve the same exact effect by blurring the image by being out of focus. Yes, they are both achieving a similar result, but it's not exactly the same.

From what I gather, they are using the same methodology that you use on the OLPF in front of the lens. You use a few layers of birefringent material which duplicates the image in multiple directions. It's not blurred, it's actually a copy. By doing this with the right combinations and with a shift distance relative to the characteristics of the sensor, you can get excellent results (just as you would with a change to the OLPF actually already on the camera.

The other issue is that in truth, the image is not really softer because what you are doing is getting rid of false detail that isn't really there. It's a product of the aliasing.

This is really an amazing product.

Also, with respect to the 5Dmk3, don't assume it will fit that if it needs it. The inside body might be different and it might not fit.

I would imagine each sensor needs its own filter design.
 
Bloom reports hard time using Nikon AI lenses on the 5D with the filter. The index post on the lenses can get caught on the filter. He couldn't get his off for a while then did but broke the mirror. Bummer. This is very disappointing since all I have is Nikon Nikkors! :/

Ah, that is unfortunate. Mine is working great with Canon lenses. It's doing its job well.
 
They want $80 to ship one of these to Australia! For the cost of 2 of these I could buy a GH2. With new full frame DSLRs due from Canon and Nikon I think I'll pass.

Am sorry but that is a rather daft thing to say. it softens the image a tiny amount but the image is still sharp. if you shoot out of focus by a foot or two you know what? it IS called out of focus and will be soft. Watch the test video I made, loads of examples for you to see in that. http://philipbloom.net/2011/09/13/moire-2/
