Patent: Canon EF 300-600 f/5.6 w/1.4x TC

Patent: Canon EF 300-600 f/5.6 w/1.4x TC

Super telephoto patent
A new Canon patent showing other lens formulas using a built-in 1.4x teleconverter. Two of the primary lenses are an EF 300-600 f/5.6L IS 1.4x and a 600 f/4L IS with a built in TC.

The same patent also shows the EF 200-400 f/4L IS 1.4x TC. Perhaps Canon sees value in this setup for longer lenses? Here’s hoping so.

Example 2

  • Focal length f = 585.10mm
  • Fno. 4.12
  • Half angle ω = 2.12 °
  • Image height Y = 21.64mm
  • The overall length of the lens 467.32mm
  • BF 83.15mm
  • Teleconference insertion
  • Focal length f = 819.00mm
  • Fno. 5.77
  • Half angle ω = 1.51 °

Example 3

  • Zoom ratio 1.90
  • Focal length f = 307.50 – 585.00mm
  • Fno. 5.88
  • Half angle ω = 4.02 – 2.12 °
  • Image height Y = 21.64mm
  • The overall length of the lens 405.00mm
  • BF 75.70mm
  • Teleconference insertion
  • Focal length f = 427.00 – 812.33mm
  • Fno. 8.17
  • Half angle ω = 2.90 – 1.53 °

How to Trigger a Light from 1600 Feet Away With the PocketWizard Plus III

How to Trigger a Light from 1600 Feet Away With the PocketWizard Plus III

From our own Justin Van Leeuwen
Our reviewer Justin spent some time with the Canon EF 200-400 f/4L IS 1.4x and did a review that didn’t include birds or bears. One of the shots was a unique model shoot using the lens as well as the PocketWizard Plus IIIs so he could trigger his light from 1600 feet away!

Says Justin about the PocketWizard Plus IIIs
“What impresses me though, is that those PocketWizard’s made it from transmitter on the camera to receiver 1600 ft away, over a moving river, up to a cliff, and set off my Elinchrom Quadra pack reliably and consistently. Wow. I highly recommend these if you ever need to shoot between provinces or states.”

Review – Canon EF 200-400 f/4L IS 1.4x

Review – Canon EF 200-400 f/4L IS 1.4x

Our review of the Canon EF 200-400 f/4L IS 1.4x
Justin took the EF 200-400 f/4L IS 1.4x out for a whirl. We wanted to do a review of the lens shooting something other than wildlife and sports, which is obviously the target shooter for this lens.

I have yet to personally use the lens in any serious manner, I won’t be doing that until April when I travel to Namibia and South Africa.

Says Justin
“If you were to buy Canon’s 600mm f/4 L and the 400mm f/4 L, you’d be getting pretty close to $20,000 worth of glass. If you were to buy several of the faster primes, that number would double. If the versatility of a zoom is what you need and f/4 doesn’t bother you (and for many of us, it really doesn’t), then the Canon 200-400 f/4 L IS USM Extender 1.4x is, in itself, a bargain. Quality build and optics and the unique advantage of a built-in 1.4 extender will help keep photographers working with a single lens, yielding them more shots, more keepers, and better work.”
