Canon EF 24-105mm f/4L IS vs Sigma 24-105mm f/4 OS Comparison (Lensrentals)

Sigma 24-105mm f/4Sigma 24-105mm f/4

Lensrental’s Roger Cicala compared two 24-105mm lenses for full-frame DSLRs, the Canon EF 24-105mm f/4L IS (price & specs) and the Sigma 24-105mm f/4 OS (price & specs).

It’s a pretty technical article, yet it is understandable also for people not into engineering. In the conclusion Mr. Cicala writes:

Sigma has made a very nice zoom here at a very good price. It’s obviously not going to create the stir that occurred with their 35mm f/1.4 or 18-35 f/1.8 lenses, but it’s a nice addition to their lineup.

Canon shooters who have a 24-105 f/4 IS have no reason to change based on optics as long as the promotional pricing remains in effect. The Sigma and Canon 24-105s are nearly identical. Similarly the Nikon 24-120 has been available on discount lately, so I don’t see a big motivation for Nikon shooters to change, either.

Of course, if the pricing changes I wouldn’t hesitate to buy the Sigma instead of the name brands. If nothing else, I think the presence of the Sigma will keep Canon and Nikon prices reasonable.

Canon Patent For New 16-35mm and 17-40mm Lenses (?)

Canon Patent Canon Patent

Egami (translated) spotted some interesting patents filed by Canon.

The patent refers to new 17-40mm and 16-35mm lenses, as you can see with apertures between f/2.8 and f/4. Are these patents for the replacements of the EF 16-35mm f/2.8L II USM and the highly popular Canon EF 17-40mm f/4L USM lenses? These two lenses were measured by DxOMark a few weeks ago.

Canon Article Gives Insight Into Dual Pixel AF Upgrade For Cinema EOS C100 (no sensor swap)

Upgrade For Cinema EOS C100

Canon EOS C100: Adorama | B&H

The Canon Professional Network Europe published a short yet comprehensive article about the Dual Pixel CMOS Auto-Focus update now available for the Canon Cinema EOS C100 (price & specs). The upgrade is now available via Canon Regional Competence Centres in Europe. If you read the press release it sounds as if the Dual Picel AF is already on board on the C100, since Canon states that the upgrade “utilises the existing Super35mm sensor in the EOS C100“. So are you paying €400/£340 just to unlock the Dual Pixel AF feature?

Canon has announced that a major feature upgrade – the addition of Dual Pixel CMOS Autofocus – is now available for its EOS C100 Digital Cinema Camera via Canon Regional Competence Centres in Europe.

The EOS C100 is a large sensor video camera that’s designed with the single shooter in mind – it already offers functions such as One-Shot AF, Push Auto Iris, auto white balance and a built-in microphone to aid individual camerawork. The Dual Pixel CMOS AF upgrade for the EOS C100 will expand the shooting possibilities by providing smooth, accurate autofocus with a huge range of lenses. For cameramen requiring more precise control the responsiveness of the One-Shot AF function has been greatly enhanced with increased focus speed.

The upgrade, an extra-cost option, utilises the existing Super35mm sensor in the EOS C100 and can be booked in at the Canon Regional Competence Centres* in France, Germany, Italy, Sweden or the UK – see later on in this article for more details of how to book in your upgrade. * Please note: if your country is not mentioned below please contact your local Canon Video Service Centre to book in your EOS C100 upgrade.
