Canon 5D Mark III without optical low pass filter – the verdict

I’ve shot a comparison in Berlin today between my modified 5D Mark III and the standard 5D Mark III.

The modified 5D Mark III is similar to the Nikon D800E in that the anti-aliasing filter has been removed. (Which is why the modified 5D Mark III is dubbed 5D3E in the video).

But is it any good?

Shootout in extreme low light – 5D Mark III vs FS100 vs GH2

This is a torture test of the low light abilities of 3 cameras. There are three test scenes in a battered old ex-factory in the east of Berlin. The first consists of a completely pitch black room with glowing pearl lighting. The next one is in the roof is lit using a single iPhone 4S torch with the cameras ramped up to ISO 12,800. The third scene is again a pitch black dark room with the lights of a building outside reflecting in a mirror on the wall.

How I opened my 5D Mark III – and why you have to be crazy to do it

5D Mark III's sensor unit and OLPF

First and foremost – a huge thank you to James Miller for the inspiration and guidance

Disclaimer: I accept no liability, nor can I recommend this risky operation on your camera unless you are totally insane!

Over Easter I disassembled my 5D Mark III. The aim is to remove the optical low pass filter that sits in front of the sensor block, a drastic operation pioneered by James Miller last week. Removing it increases resolution in video mode and makes for a sharper image with no digital sharpening in post required.

With results that good on offer, why do you need to be bonkers to try it? Read on to find out how the teardown went…

Mosaic Engineering working on Nikon D800 anti-moire filter

D800 and Mosaic Engineer anti-aliasing filter

Good news for Nikon D800 owners. Mosaic Engineering are currently working on anti-aliasing filter for the camera. Because the sensor line-skips to produce HD video, the custom-designed optical low pass filter should almost eliminate any moire and aliasing on the D800 if it works as well as it did on the Canon 5D Mark II.

UPDATE: James Miller removes optical low-pass filter from 5D Mark III for resolution increase / new footage

Update: James has had a full day’s shooting now with the modified 5D Mark III. Check out the footage above.

Warning: please wait for this to all shake out. Don’t hastily modify your 5D Mark III without the necessary technical knowledge and research. Opening the camera voids the warranty and risks irreparable damage.

James Miller has decided to open up his brand new Canon 5D Mark III, tear it down and remove the blurring anti-aliasing filter from in front of the sensor. It does seem like a particularly strong optical low pass filter on this camera, which produces very soft results in video mode.
