By Canon Rumors | May 16, 2016 | Canon Business General

The EOS M patents continue to flood in, this time we get a patent for an EF-M 15-50mm f/3.5-5.6 IS STM optical formula.

Patent Publication No. 2016-75742 (Google translated)

  • Published 2016.5.12
  • Filing date 2014.10.3
  • Zoom ratio 2.94
  • Focal length 16.00 27.43 47.04
  • F-number 3.62 4.50 5.82
  • Half angle of view (degrees) 37.55 26.47 16.19

  • Overall length of the lens 78.86 74.05 77.88

This definitely looks like a kit type of zoom lens from the upcoming EOS M body, which we expect to be announced before the end of 2016.

Review – Tamron SP 85mm f/1.8 Di VC USD

Review – Tamron SP 85mm f/1.8 Di VC USD

By Canon Rumors | May 16, 2016 | Canon Reviews

Dustin has completed our review of the Tamron SP 85mm f/1.8 Di VC USD lens. This is a very desired focal length and Tamron is the first to bring us a new 85mm lens in a long time. Both of the Canon offerings are getting long in the tooth and we’re all waiting for Sigma to bring us an Art series 85mm f/1.4.

It appears Tamron’s goal was to bring a lens of great optical quality, manageable size and weight as well as good durability with weather sealing.

From the review:

Tamron has charted their own prime lens path with this new SP prime series, and it is clear that they have been doing their homework in the development of these lenses. Their decision to produce prime lenses with stabilization but slightly smaller maximum apertures has allowed them to keep the size moderate with these lenses despite resolution figures up there with the very best. Their choice to really invest in serious weather sealing for their lenses helps set them apart from the competition. Read the full review

I’m actually going to purchase one of these for my EOS-1D X Mark II for an upcoming trip because of the weather sealing alone. The size and optical quality are going to be an added bonus. I will be paying close attention to the autofocus performance of the lens, but for what I’ll be shooting, I’m confident it will perform well.

You can file this one under the “heard it from a Canon rep”, which going by past experience, rarely turns out to be accurate. However, I and others have been told that the upcoming Canon EOS 5D Mark IV would be “32mp with 24mp mode”. What a “24mp mode” would be beyond an MRAW setting is unknown.

All we know for sure about the EOS 5D Mark IV at the moment is that it will be announced in August for Photkina and should be in your hands by October of this year.

Canon EF 16-35mm f/2.8L III Coming in June [CR3]

Canon EF 16-35mm f/2.8L III Coming in June [CR3]

By Canon Rumors | May 12, 2016 | Canon Lens Rumors

We’re told that we can expect to see the Canon EF 16-35mm f/2.8L III to be announced in June of 2016, and availability coming fairly quickly, likely by the end of July.

A person who has used the EF 16-35mm f/2.8L III says it’s every bit as good as the recent L offerings from Canon and “solves the most glaring weaknesses of the current version.”

We haven’t been told anything about pricing yet, but we hope to hear more about that in the coming weeks.
