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.

Scott Bourne and the 5D Mark III

This is the most hilarious review about Nikon’s D800 I’ve ever read. Scott Bourne reviews it, and while doing the review he praises the EOS 5D Mark III. Funny. Needless to say: he also considers the AF of the 5D Mark III superior to the AF featured on the D800. The lower price tag is also demystified, since having a 36MP sensor means having bigger files, and that means you eventually have to invest in new computer equipment: […] you better also plan on buying more and larger hard drives, a faster computer and more and larger memory cards. The files coming off the camera are at least 40 megabytes. Do the math! […] that means you’ll need three times the hard drive space and three times the camera memory. Add that to the cost of the camera and it’s not quite the bargain it appears to be compared with the 5D MK III. Also – get used to going for coffee while your images import.

About the Auto-Focus: The Nikon D800 also has a few small problems. Its autofocus doesn’t work as expected. It seems to do an initial grab and then fine tune. The AF on the D800 is in my opinion, inferior to the AF on the 5DMKIII.

EOS 5D Mark III DXO-Marks published, and then not – PUBLISHED

Update 2: The scores are online again. Nothing changed.

Update: the scores have been posted in DPreview forum. Here they are. The measures reported for the EOS 5D Mark III are the same I saw: 2239 ISO – 11.7 EVs DR – 24 bits color depth, overall score 81. This measures look strange to me, especially when compared to the 5D Mark II and Nikon’s D800:

  • 5D Mk II – 1815 ISO – 11.9 EVs DR – 23.7 Color Depth, overall score 79
  • D800 – 2835 ISO – 14.4 EVs DR – 25.3 bits Color Depth, overall score 95

 

Just a quick note that the posting of the EOS 5D Mark III DXO-Marks could be a matter of minutes. I saw them just 10 minutes ago but now it says that scores are not available. I wont tell you the overall score i saw, could have been a typo. :-)

Stay tuned!

To Upgrade or Not To Upgrade, part 1: 5D Mark III vs 5D Mark II

VS 

It’s a month and a half that the EOS 5D Mark III has been announced, and a lot of people is questioning if they should upgrade from their actual cameras. In this post I try to compare the Mark III with its predecessor, the EOS 5D Mark II, and to outline the main differences between the two cameras. In the second part (in a few days, hopefully) I will compare the 5d Mark III with the EOS 7D.

The EOS 5D Mark III is a completely redesigned camera (also in its internal assembling), with a new AF-system (the most advanced available on a DLSR), a sensor that has one megabyte more resolution than the Mark II and a new CPU. Let’s first see the core specifications:

Canon stopping EOS 5D Mark III shipment (?) – UPDATE

UPDATE 5: thedigitalpicture is reporting that Canon USA will not stop shipment of the EOS 5D Mark III. No sources are named.

UPDATE 4: This was posted in the clubsnap forum and then reported by canonrumors, apparently the answer of Canon Singapore to a concerned customer: With reference to your question on whether Canon Singapore will recall the EOS 5D MK III due to the light leak issue, we wish to inform you that we will not. However we will contact you later this month to rectify this issue. Please leave us your contact number for our Service team to contact you.

UPDATE 3: Things are getting worse. Canon France, asked by focus-numerique (Google translated), says that: Canon states that all cases seem to be unaffected and that ultimately the problem is marginal. For now, the 5D Mark III deliveries are slowed in France in order to check current inventory. The distribution is expected to resume a normal pace in the month of May.

UPDATE 2: Adorama, Amazon and B&H all have the out of stock and available only for pre-order. Don’t know if this is related to the supposed hardware problems of the Mark III, but at least it is a strange coincidence. Quoting Adorama: This item is currently out of stock and on backorder. Please note: You can order this now and have us ship it as soon as it arrives. We will not charge your card for any backordered items, until it is ready to actually ship.

UPDATE: Changed the title since techradar is reporting: Canon UK has said that shipping of the 5D Mark III has temporarily stopped while it investigates problems with the top LCD causing exposure issues. Following techradar, the Canon UK spokesperson could not say when shipping will resume.

The EOS 5D Mark III light-leaking problem – An analysis

These are not rumors, but a logical analysis of the possible scenarios related to the light-leaking issue that some customer experience on their EOS 5D Mark III bodies. I reported about this issue, in short: metering gets altered by light leaking trough the top LCD panel of the camera. Canon’s official statement: In extremely dark environments, if the LCD panel illuminates, the displayed exposure value may change as a result of the AE sensor’s detection of light from the LCD panel. Unfortunately, this seems to happen with both the backlight of the LCD panel and strong direct sunlight hitting the panel. Next, we heard that some new batches of the 5D Mark III had a different top LCD panel cover than previous ones. And then there are rumors that the EOS 5D Mark III could be recalled by Canon. So, what is going on? How will Canon fix the problem? I try to outline different scenarios. Again, not new rumors I heard but my very own analysis of the issue.
