Powershot G1 X DxO-Mark Scores and Lens Test

DxO Labs just published the measures for Canon’s Powershot G1 X, and the little cam scores good, very good. DxO Labs’ interpretation of the scores:

  • You have a reflex-quality sensor in camera of the same volume as a G11.
  • You can use this camera even under relatively difficult conditions.
  • If you’re an amateur photographer, this camera can satisfy pretty much all of your needs (especially if you want to take great family photos, for example). If you’re a professional photographer, this can be a good backup camera.

Compared to other, similar cameras, the G1 X outperforms almost all of them (overall score is higher in any case) or has a score that can hold up with Canon entry level DSLR’s. Read more after the break.

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:

EOS 5D Mark III strip tease: Perfection where you can’t see it.

What do you do if you rent out a camera and it comes back with a loose screw inside? You probably would send it in to a service center to get the problem fixed. But if you have the necessary technical skills (and you really need this skills) you may also decide to tackle the problem by yourself and to open the camera to find that damned screw that’s rattling around inside. This is what Roger Cicala of lensrentals.com must have thought as he got such a camera body in his hands. It happened to be an EOS 5D Mark III, and he posted the report on imaging-resource.
