First thing to know about B4 Lenses is that they are originally made for broadcast ENG cameras which has a smaller sensor size than DSLR or M4\/3 cameras, with the biggest sensor size being 2\/3 inch then 1\/2 and 1\/3 being the smallest. However the smaller sensor sizes also often have a B3 mount instead of a B4. Below is an image of a B4 mount removed from the lens and a B3 is more like an inverted version of the Bayonette.<\/p>\n

And of course the bigger the better, with the 2\/3″ lens and with a 2x extender which also doubled he size of the image projected on the sensor help it quite allot, as it will fit the 4\/3 sensor easily.  But lets list  the pro’s and cons of actually using a B4 lens.<\/p>\n
