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…

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.

Canon 5D Mark II – Mosaic Engineering VAF-5D2 anti-aliasing filter review

Tuesday, 28 February, 2012 20:07

A great many have forgotten what an absolute beast the 5D Mark II is.

A power house of image quality with a massive sensor, Hollywood film sequences and entire episodes of prime time network TV have been shot on it purely for the way it looks. But it does have one big flaw.

This is now much reduced with the VAF-5D2.
