Here are Some Interesting Lens Mentions We’ve Received [CR1]

The rumormill is a bit slow at the moment, but that hasn't stopped lots of folks writing in with gear that may be on the horizon.

I figured it would be fun to let you know about a few lenses people have claimed are coming in the not-too-distant-future from Canon. I rate all of these lenses as unlikely, but I've thought that in the past with other lenses, only to see a couple of them turn out to be true.

There seems to be an abundance of lenses with built-in TC's hitting my inbox.

• Canon EF 400mm f/2.8L IS 1.4x / 2.0x TC
  A crazy replacement for the EF 800mm f/5.6L IS with two built-in teleconverters?
• Canon EF 600mm f/4L IS 1.4x TC
  Another lens to replace the EF 800mm f/5.6L IS?
• Canon EF 200-600mm IS w/1.4TC
  A new superzoom with a built-in TC? Highly unlikely, but a nice thought nonetheless.
• Canon EF 14mm f/2L
  A faster replacement for the EF 14mm f/2.8L II?
• Canon EF 50-300mm f/2.8-5.6 IS DO
  One of the more creative wishlist lenses? I doubt we'll see a DO zoom again.

I would rank all of these rumored lenses as unlikely, but a couple of them may be worth a discussion.
