Sigma 85mm f1.4 at f1.4 1/640th iso 125
Previously we did a quick test with the Sigma 85mm f1.4 EX and the Canon 85mm f1.2 L. Before that, we compared the Sigma lens against the more affordable option in Canon’s lineup, the 85mm f1.8. Eventually, I was able to bring the two lenses out into Central Park for a quick portrait session with Kathy. The results? You may be surprised.

One of these images was shot with the Canon 85mm f1.8 and the other one was shot with the Sigma 85mm f1.4. Both were shot on the Canon 5D Mk II and only had profile corrections applied. Can you tell which image is from which lens? Let us know in the comments below!
Full comparison review is coming tomorrow. The EXIF Data for each image has been left in tact, but no peeking! Click each image to view them at full size.

With the Leica M9P
(or M-9P and M9P) around for a little while, I decided to put it up against my trust Canon 5D Mk II
and the Olympus EP2
(or E-P2 and EP-2) to see how the high ISO noise levels are. Granted, all three of these are different cameras: one is an EVIL camera, one is a DSLR and the other is a rangefinder. They are all used in different ways, but one of the complaints that many people state on street photography, photojournalism, and wedding forums is that the 5D Mk II is the only one with good enough high ISO capabilities.
Well, is it? Take a look at our non-scientific test and judge for yourself.

Upon browsing through the Editor’s Choice area of 500px.com, I noticed this image. When you upload an image to the service, it automatically puts the EXIF Data in for you. However, it can be changed if you go in and edit the information. Apparently, Christopher Boffoli may have a Canon 5D Mk III. Christopher may have mistakenly put that in. If he did, then too bad. But if it really is an image from the 5D Mk III camera (that has yet to be announced), fanboys all around will be ecstatic.
He has comments on the image already asking about the Mk III but not replying at all. That just peaks my curiosity even more. What do you think? Could it be real? Why would he not correct it and prevent angry Canon fans from potentially ripping him apart?
Update: he has removed the camera information!!!!!!

According to DXoMark, the Fuji X100 has an amazing sensor and it has been rated to be better than the Canon 5D Mk II and the 7D (correction: the 5D Mk II is still rated to be better). With the announcement of the Olympus EP3, I decided to put the camera against the two DSLRs myself. So how does the new internally developed sensor do against the mainstream giants?
Disclaimer: Yes, we know the sensor are different sizes. Yes, we know that you’ll go over to other sites to look for this information anyway. Yes, we are trying to answer the question for you.
