Canon Dual Pixel AF with Tamron SP 35mm and SP 45mm f/1.8 primes (both shipping)

Short video by Dustin Abbott showing Canon’s Dual Pixel CMOS AF used on the new Tamron SP 35mm f/1.8 VC and Tamron SP 45mm f/1.8 VC. It’s not as silent as Canon’s STM lenses, but for the rest it seems to work good and smooth. Dustin Abbott also posted an exhaustive video review of both lenses. Dual Pixel CMOS Auto-Focus is featured on the EOS 7D Mark II and Canon EOS 70D, and on Canon’s Cinema cameras. Tamron’s new primes captured a lot of attention since they were announced. For a good reason. The SP 35mm f/1.8 Di VC USD and the SP 45mm f/1.8 Di VC USD are affordable, and have weather sealing and image stabilisation. That’s a lot of bang for $599. Both lenses are now shipping.


Canon EOS C300 Mark II impression by LensRentals


The folks over at LensRentals posted a first impression about the Canon EOS C300 Mark II. When talking about performance, they write:

Surprisingly, the thing that impressed me most in my time with the Canon C300 Mark II had nothing to do with resolution, bit rate, or dynamic range. Digital video technology has improved so much in just the last few years that those specs, while enormously important, aren’t enough on their own to make me choose one camera over the other. There are simply so many great digital cinema cameras on the market right now that it takes a wholly original feature to make a camera stand out. In the case of the Canon C300 Mark II, that feature is autofocus. Read the review at LensRentals.

What makes the auto-focus so powerful is Dual Pixel CMOS Auto-Focus technology, featured also on the EOS 7D Mark II and Canon EOS 70D. Below you see two test videos shot with the C300 Mark II. You may also be interested in a C300 Mark II white paper Canon recently published.
