The recently-rumored Canon EF 24-70mm f/4L IS has been confirmed through an image and spec leak alongside a new EF 35mm f/2 IS lens.  Additionally, the EF 24-70mm f/4L IS lens will be a kit lens for the Canon 6D, which should ship in December.  Apparently, the rumored 50mm f/1.4 IS lens will not be making its way out this round.

The EF 24-70mm f/4L IS lens may end up replacing the current 24-105mm f/4L IS as the defacto kit lens for other full frame DSLRs going forward.  That’s just speculation; however, the lenses completely overlap.  Of course, some will deride a decision to go with the shorter lens as compared to the longer reach offered by the 24-105mm version; however, there’s no denying the reduced footprint and weight around your neck offered by the 24-70mm f/4L IS.

The 24-70mm f/4L IS lens is believed to weigh only 600g, while the 24-105mm f/4L IS weighs in at 670g.  Likewise, the 24-70 is believed to be 93mm max length, while the 24-105  max length is 107mm. [Read more…]
