Not only camera specs and images are leaking now and then, but eventually also the mighty DXOMarks are handled as genuine rumors. And here they are: Canon EOS-1D X DXOMark leaked. For what ever this score is worth in real life, here are the (supposedly) leaked scores for the Canon EOS-1D X, yet not published on dxomark.com:
DxO score: 90
Color depth: 24.9 bits
Let’s make it short: below the Nikon D600 and D800.
The 24-70mm is a wide-angle to medium telephoto range that’s popular with full-frame shooters (e.g. photojournalists), so I thought it would be a good idea to write a 24-70mm lenses reviews round-up. Canon, Sigma and Tamron are the brands of choice. If used on a APS-C sensor, the lenses give you an equivalent of 36-105mm.
Canon recently released the EF 24-70mm f/2.8L USM II lens ($2300) to succeed the now discontinued EF 24-70mm f/2.8 USM (still available on eBay for around $1800). Canon’s new EF 24-70mm f/2.8L USM II has a rather hefty price tag, and no image stabilization. Being an “L” lens it is totally weather sealed, and the overall build quality is on line with Canon’s “L”-philosophy. The video above and the sharpness test below feature the “old” EF 24-70mm, which also comes without image stabilization.
The Tamron SP 24-70mm f/2.8 DI VC USD ($1,299) is cheaper than both Canons and has image stabilization(VC), making it an interesting alternative. The weather sealing of the Tamron is defined as a moisture-resistant construction [that] helps prevent water from penetrating the lens. For a lab test of the Tamron click here. And then there is the Sigma 24-70mm f/2.8 IF EX DG HSM ($899), no image stabilization, no weather sealing and definitely the less expensive of the three. A review of the Sigma can be read here.
At learningdslrvideo they were particularly interested to compare sharpness. They used a Canon EOS 5D Mark III for the tests. The results are discussed in the video above. That’s what they found out:
f2.8: Tamron beats Sigma (Sigma looks bad in the center and edges), Canon beats Tamron ever so slightly at center and edges
f5.6: Sigma beats Tamron at both center and edges, Canon beats Sigma only at center, edges are a tie
f8.0: Sigma and Tamron tie, Canon wins slightly
f16.0: All three tie
f22.0: Sigma does a nice job beating both Tamron and Canon
f2.8: Sigma beats Tamron in the center, Tamron beats Sigma in the edges, Sigma beats Canon in center, Canon beats Sigma in the edges
f5.6: Sigma and Tamron tie, Sigma beats Canon in the center
f8.0: Tamron beats both Canon and Sigma
f16.0: All three tie
f22.0: All three tie
The Sigma may not have the excellent build quality of the Canon, nor it has any sort of weather sealing like the Tamron. Nevertheless, the Sigma has an excellent build quality), and its sharpness is good. Obviously sharpness is not the only concern for a photographer (though one of the most important). However, the Sigma is much less expensive than the Canon and the Tamron.
The next video shows a 24-70mm Canon vs. Tamron shootout (by youtube user TheCameraStoreTV). This time the new Canon EF 24-70mm f/2.8L USM II lens comes into the game.
The Canon EOS-1S high megapixel DSLR may have the body of the EOS-1D X
Rumors about the Canon EOS-1S high megapixel DSLR are getting stronger. More information is leaking and confirms the previous tidbits. We can be confident that something regarding a high megapixel DSLR (46MP are rumored) will actually happen. However, the new information are stating that if Canon announces the high megapixel DSLR (supposedly named EOS-1S) in 2012 it will be just a development announcement, and not an announcement of imminent release. Other Canon gear has been announced years before being released. The good news: It should be rather sure that Canon is testing prototypes.
The Canon EOS-1S high megapixel DSLR is said to have the same housing of the EOS-1D X, 10fps and 46 MP. It is also said that the EOS-1S will employ a new sensor technology that delivers unseen low ISO performance. And a seldom seen price tag too: it’s said to get over the counter for $9000. That’s all we know so far. I wouldn’t bet on the name, it is not the first to be suggested (3D and 4D and 1D-S were rumored). However, suggestions that it will be a “D”-less name are getting louder. So let’s call it EOS-1S for the time being. A last word about the new sensor technology: It has been suggested that Canon could introduce a new DSLR category with the Canon EOS-1S high megapixel DSLR.
It’s time that Canon comes back with some exciting technological break-through. A 46MP monster by Canon has to be a killer DSLR. We will see…
