    The Canon EOS 5D MARK III
    OLPF Removal Project





    " The video image quality now, is not the same 5D Mark III that came out weeks ago. It's as if the camera was transformed. "The mushiness is gone" It never made sense that 4 years later, all new chips , Digic 5, and the image was soft on the 5D Mark III. Well, we know why now."

    James Miller ( his vimeo below ) removed the optical low-pass filter from his 5D Mark III to achieve for higher resolution.
    It's like an entirely different image coming from the 5D Mark III. Definitely download the 1080P for the best resolution.



    UPdate: 4/01 SECOND VIDEO POSTED. Download the 1080P for stunning quality.



    I mentioned days ago- I was curious why the Marionette short film from Canon shot on the 5D Mark III looked so much better ( more detailed ) than what was coming from the 5D Mark III videos filmed with the shipping cameras. Did the pre-production models have a different OLPF? I guess anything is possible. Never the less the results of removing one of the OLPF's looks good and this is ongoing. We will not know for sure until more accurate tests can be done. Either way the 5DMark III is an improvement in other aspects to it's predecessor.


    Frame grabs with a slight USM applied- Without the OLPF the images are already sharp now from the 5D MARK III, however I wanted to see how a little USM applied would look.




    James Miller the brave 5D Mark III owner and hacker/modifier wrote:
    " What is the aliasing like now? Well I was prepared for a terrible mess but I was really happy with the first few tests, I can’t really hardly spot any problems of Aliasing and thus Moire. And also I think the RAW still images have benefited from this also.."


    The breakdown of the Canon 5D Mark III to the senor & then to the OLPF.


    THE THIRD MAN! Bill DePalma removed his OLPF from his Canon 5D Mark III- He are a few words from Bill:
    "it was a very nice improvement. I doubt that I would be tempted to add any post sharpening at this point.
    There is IR contamination to some degree as my footage is biased a few points red, I knew that going in, though.
    Was it worth the cost both to get it done and nullify the warranty - who knows, but I don't regret getting it done."

    5D3 OLPF Removed by Bill DePalma: Download the 1080P file for best quality file.




    Maxmax.com- A Company that offer's OLPF Removal Info posted by marvinhello.
    According to Maxmax.com, the company that offers service to remove the OLPF on 5D2 and 5D3, Canon DSLRs have two OLPFs, one for vertical blur and one for horizontal blur, the horizontal blur OLPF is epoxied on the sensor, it's very difficult to remove without damaging the sensor. They told me that human eye is most sensitive to vertical blur therefore removing the outer OLPF can bring significant sharpness improvement. However they can remove both OLPFs for extra charge.

    When the outer OLPF is removed, they will replace it with an IR cut filter that has the same thickness. They also can transplant the dust removal system to the IR cut filter for an extra $175.

    Total cost of removing one OLPF and have dust removal system working is $400+$175+$20 shipping=$595

    As I've mentioned, Maxmax.com will replace the outer OLPF with an IR cut filter, it has exactly the same thickness as the OLPF, so light path won't be affected, autofocus and infinite focus will function as normal, they will also recalibrate the camera for you when it's reassembled to make sure focal flange is correct.

    The dust removal system (a vibrating strip) is originally attached to the OLPF, for extra $175, they can remove the strip from the OLPF and attach it to the new IR cut filter, hence preserving the dust removal ability.



    Another 5DMark III gets it's secondary OLPF removed. Andrew Reid at EOSHD takes the plunge!
    http://www.eoshd.com/content/7813/ho...crazy-to-do-it

    So getting down to what's important- Andrew of EOSHD wrote:

    "Absolutely no sign of moire or aliasing and a nice feel to fine detail. It is very close to the GH2 / C300. But full frame!!"

    "Footage looks more cinematic, more organic."


    It becomes painfully clearer everyday that Canon didn't need to add that secondary OLPF to the cleaning system mechanism.



    If you would like Canon to offer a 5DMark III with the secondary OLPF removed from the self cleaning panel. Contact Canon and put in a request (If Nikon can with their D800E, Canon could as well)

    Here are some nice looking shorts shot on the 5D Mark III stock- No OLPF removed.

    Entertaining for sure, but I'm not yet convinced it's worth it. See my comments and processed images here: http://www.dvxuser.com/V6/showthread...solution/page4

    Also, my brick wall test now has full res file available to download from vimeo:
    https://vimeo.com/39552988

    How does it compare, resolution-wise, to the OLPF removed example?

    Should probably re-upload the Veyron footage at 1080p to vimeo...

      It sure looks good so far. Watching the 1080P download, it's kinda like a GH2 sharpness at full frame. That OLPF is very aggressive, why Canon went with that is interesting. It just came about, so obviously we need to see more tests, however it looks good at this stage. Maybe Canon should offer two versions like Nikon's D800 vs D800E.

        Even watching the 1080 vimeo stream non download it's almost enough to make me blow a lot of money I don't have, then a warranty I might need.

        If this is what sharpening would've looked like then I would've had one a long time ago.

          Well. That looks amazing. Honestly, I see a significant difference between that and the post-sharpened clips after downloading the raw file.

              A: It has two of them. This is just the outer one that doubles as the self cleaning plate. An IR cut filter and 1st OLPF are fixed on the sensor assembly. Not removed here.

              Interesting..... Makes you wonder Emanuel. Looking at the video in 1080P, it's like a whole other image. Maybe Canon could offer a version without that secon OLPF, like Nikon's D800E.

                    Seriously- Kholi this is what I would have expected form the 5DMIII in the first place. High strangeness on Canon's part. Funny it hasn't been out more than a few weeks, and it's already getting modified to reveal hidden image quality.

                    I mentioned days ago, I was curious why the Marionette short film from Canon looked so much better ( more detailed ) than what was coming from the 5D Mark III videos filmed with the shipping cameras.

                    Were the pre-production models missing a soft element? An OLPF? "Just saying!" Food for thought........

                      I agree... but even the marionette videos do not look like this. At all. This looks like footage from something else completely.

                        na had lots of pre-production expenses last week. Hopefully I'll have it by Thursday....I have to start shooting on the weekend

                        I suspect no OLPF won't look much different to post sharpened res/detail wise
