Hacked EOS 5D Mark III: More footage
More footage shot with a modified EOS 5D Mark III has been published. I reported about this hack made by James Miller (here, here and here). The mod consists in removing the OLPF (Optical Low-Pass Filter) from the sensor of the 5D Mark III. The result: an increase in resolution. The surprising thing is that neither moire nor aliasing become a real problem without the OLPF (aka Anti-Aliasing filter). Without the OLPF filter the sensor becomes also more sensitive to IR light, making the 5D Mark III suitable for astrophotography. To fully enjoy (and analyze) the footage it’s better to login to Vimeo and to download the uncompressed version of the video.

2 years ago |I would worry about the accuracy of the AF after removing the filter (and also the blacks). Someone needs to come up with a a replacement module that removes the OLPF but keeps the focus accuracy intact and the self-cleaning module intact. I guess the color could be corrected in post.
If you look at Nikon USA’s site, you can see the differences between the images of the D800 and the D800E (bottom half of the page):

Nikon says the D800E would give you a “slight increase in sharpness and resolution with increased occurrence of false color and moiré”

2 years ago |Reading the EOSHD forum post, it seems that Maxmax.com is replacing the OLPF with a glass of the same thickness to maintain the AF accuracy and keep the cleaning module intact. These is very good news. It would have been better if they could implement a IR filter of sort instead of the glass to correct the color shift but that can be corrected in post (or by using an IR filter on the lens).
