Canon Rumors is reporting some big news if you're in the market for a new 70-200mm lens. According to the rumor site, it's a near certainty that Canon will be debuting two new 70-200mm lenses in early June: the Canon EF 70-200mm F4L IS II, and the Canon EF 70-200mm F2.8L IS III.

Both of the current versions—the Mark I of the F4L and the Mark II of the F2.8L—are certainly due for an upgrade. The 70-200mm F2.8L IS II was released in 2010 and the F4L IS even farther back in 2006. Meanwhile, third-party manufacturers like Tamron and Tokina have released their own 70-200mm F2.8 and F4 lenses more recently, and Sigma confirmed to DPReview that it will release its much-anticipated 70-200mm F2.8 Art lens "not too far in the future."

In other words, early June would be a great time for Canon to get the jump on Sigma and fight back against the Tamron 70-200mm G2 that people have been so positive about.

The good news is, this isn't just a thin rumor. Canon Rumors says they can "100% confirm" that the 70-200mm F4L IS II is coming, and "95% confirm" that the 70-200mm F2.8L IS III will join it. Of course, as the rumor site points out, lens announcement and release dates can change at the last minute, but we'll be keeping our fingers crossed for both these announcements in the coming month.
