DreDaze happy with myself for not saying anything stupid  More info | Nov 29, 2012 01:05 | #2 i think the MFD is the same throughout the range...in order to get the .7X magnification though you need to switch it to macro mode...in which case the MFD is closer...it's supposed to only give 3cm of working distance from the front of the lens though... Andre or Dre

(i initially thought it was at all focal lengths). does the MFD slowly change the closer one gets to 70mm or does it switch from the normal MFD to the close MFD? -0- i'm torn between these two lenses, anybody in the same predicament?

Nov 29, 2012 01:13 | #5 from Canon's text, Featuring dynamic L-series optical performance in a compact, lightweight and durable design, the new EF 24-70mm f/4L IS USM lens is well suited for all levels of advanced photography on the go. The ideal companion to Canon’s full-frame Digital SLR cameras such as the EOS 6D, the lens features a constant maximum aperture of f/4 throughout the entire zoom range with 15 lens elements in 12 groups including two aspherical and two UD lens elements and a 9-blade circular aperture diaphragm. The EF 24-70mm f/4L IS USM lens delivers gorgeous images with excellent detail at all focal lengths and includes a macro feature at the telephoto end with a 0.2m/7.9-inch minimum focusing distance and Canon’s Hybrid IS system (with up to four stops of stabilization). The macro feature can be engaged through a switch on the lens barrel. In addition, the lens features inner focusing and a ring-type Ultrasonic Motor (USM) for quiet, fast autofocus, and has full-time mechanical manual focus that’s enabled even during AF operation. Compact at only 93mm in length, with excellent dust and water resistance, the EF 24-70mm f/4L IS USM lens has a fluorine coating on the front and rear elements for easy maintenance and cleaning. i hope it's all throughout the range. camera bag reviews

MFD is from the sensor...so you have to take in to account the length of the lens, and that little bit that it's out from the sensor as well... Andre or Dre

The canon will likely have some bokeh issues as well. Sharp lenses = nervous bokeh.
