A new rumor in the long series of EF 100-400 f/4.5-5.6L IS replacement rumors showed up on the web.

It is said that the next “L” lens Canon will announce will the replacement for the EF 100-400 f/4.5-5.6L IS. No specs so far. The new lens is expected to be announced after or shortly before the EOS 7D replacement. The 7D replacement is rumored for Photokina 2014 (September), so the lens may be announced around this time.

(Update #3) Are Sony, Olympus and Panasonic Cheating Their Customers (crop factor with ISO & aperture)?

update #3: be sure to read Tony Northrup’s comments and answers in the comment section of this post.

update #2: I think Tony Northrup is wrong, Have a look here to grasp the whole story.

update: have a look at to get an alternative view of the issue. Says Ale from MR:

There are a couple of logical errors made by Tony Northrup.

First: No one cheats. All company aperture lens info are correct! The Panasonic 12-35mm f/2.8 has a f/2.8 aperture and not a f/5.6 aperture. You don’t have to make the equivalence he says has to be done! Use the Sony A7r and Sony A6000 for the same shoot. To get same result the camera automatically sets on both the same ISO and same lens aperture despite the different sensor size. Just to say that the aperture remains CONSTANT and is not relative! There is no equivalence to make on that!

Please read this why you cannot apply the aperture equivalence you mention on no other than the “depth of field” and “field of view” only:

The focal length and aperture remain constant!!!!

Second: He says Olympus, Panasonic and Sony do cheat. Nope. All companies use the same kind of measuring aperture for all lens formats (medium format, MFT format, APS-C and so on).

This 37 minutes video by Tony Northrup is rather technical and complex, but it is a must see if you want to understand the tricks some camera manufacturer are using to mislead their customers. According to Tony Northrup only Canon, Nikon and Fuji are stating the truth with their crop sensor specifications.

Says Tony Northrup:

Please spread the word to end the cheating: Why you need to apply crop factor to both your ISO and aperture, and how Sony, Olympus, & Panasonic use crop factor to mislead buyers

Features and benefits of the XF200 and XF205 Professional Camcorders (CPN Article)


Canon XF205

Canon Professional Network posted an article about the recently announced XF200 and XF205 run-and-gun camcorder.

From the introduction:

With today’s large sensor camera systems such as the Canon EOS 70D, 5D Mark III, 1D C and the EOS C100, C300 & C500, it would almost seem like small sensor-based camcorders are irrelevant in today’s production environments. As someone who has a long history with small sensor-based camera systems and still uses them on projects that I produce today, that couldn’t be further from the truth. There are, in fact, many situations where small sensor camcorders are actually better suited for the job at hand and are not only used daily in many facets of television and web-based video production, but also are preferred.

In this article, I will discuss some of these applications and how the CanonXF205 & XF200 represent the next generation of Canon’s small sensor-based camcorder systems that target productions where these cameras excel. I will also focus on some of the key features of the camera, such as its rotating hand grip, Wide DR Gamma, enhanced image stabilization, infrared recording and Wi-Fi features, which, together, make for a unique small sensor-based camcorder that can be used in a wide variety of today’s productions.
