Hacked EOS 5D Mark III: New footage!

WARNING: Don’t modify your camera without the necessary technical knowledge. Opening the camera voids warranty and may irreparably damage it.

We reported about this hack by James Miller a few days ago. James Miller opened his brand new EOS 5D Mark III and removed the Optical Low-Pass Filter (aka Anti-Aliasing filter) from the sensor. It seems that the filter is really blurring the image, since the pics shot without the filter are much more detailed.

Now, Miller published new material shot with his hacked EOS 5D Mark III. Removing the OLPF makes a visible difference, while moire seems not to be worsened at all and aliasing is under control. See and judge for yourself…

EOS 5D Mark III video-review by Philip Bloom

I highly recommend this 19 minutes video-review of the EOS 5D Mark III by filmmaker and director Philip Bloom. There is also an accompanying  written review on his site. Well, he is not entirely satisfied by the EOS 5D Mark III (spoiler: resolution!). While it seems assessed that the EOS 5D Mark III improved sensibly regarding to moire, aliasing, and that sound recording (and workflow, for film-makers) is now much better than before, the big question everyone is raising is resolution. The EOS 5D Mark III with is conservative approach has “only” 22MP. P. Bloom writes:

Want to master the EOS 5D Mark III/1D X AF system? Get the AF settings guidebook!


This is for all of us who want to shot (and focus) like a pro. The new Auto-Focus System on the 5D Mark III and 1D X is a complex and sophisticated beast. To harness all of its power you have to know how it works, and how to set and configure it for your purposes. Canon’s Digital Learning Center published a series of technical articles about the advanced Auto-Focus system featured on the EOS 5D Mark III and EOS 1D X.

More EOS 5D Mark III ISO performance tests and comparisons (NEX 7, D800)

Canon’s EOS 5D Mark III has such an amazing high ISO performance that I want to report more about this. It is, together with the advanced AF system and the fast burst rate, one of the features that make the 5D Mark III so much superior to its competitors (say…Nikon D800?). Ok ok, this is my opinion. :-)

Canon did the right thing when it did not put a high-res sensor in its new, year 2012, full-frame camera. Sailing upwind against the waves, Canon decided to keep a conservative resolution (22MP), to re-engineer the sensor and to update each and any system component. The result was a rock-solid performing camera, with (among other feats and tweaks) extended dynamic range, fast burst shooting, an advanced AF system, and an above-the-average ISO performance. I don’t think the 5D Mark III can be seen as a mere upgrade of the Mark II. It’s a new camera. Starting by the sensor, which got the gapless microlens technology of the EOS 1D X and has bigger photodiodes (more light) than its predecessor. Moreover, each photodiode has its own immediate noise processing of the transmitted signal. It’s the edge of imaging sensor technology, and Canon has always been one of the biggest innovators in this domain. Even Nikon knows this simple fact, that’s why they used a 5D Mark II to shot the D800 promo (click here). ;-)

Sony’s NEX 7 is not really in the same league as the EOS 5D Mark III, nevertheless I think a comparison of ISO performance is interesting. The NEX 7 is a great cam and we are curious to see how it performs compared to other new cameras, even if they have different sensor sizes (the NEX7 has an APS-C sized sensor). Mike Kobal did a extreme low-light (using candles!), high ISO test: 200-25600 on the 5D Mark III and up to 3200 on the NEX 7. How does the NEX 7 compare to Canon’s new EOS? See for yourself…
