EF300mm f/4 IS USM lens with a EF 1.4x II
Posted on January 26, 2012 by admin
A while ago we did some equipment testing and snapped together our EF300mm f/4 IS USM lens with a EF 1.4x II extender to get a focal length of 420mm at a still respectable speed of f/5.6. Since we are used to mostly shooting wider angles it was an interesting opportunity to test out interesting compositions. We shot the cranes at Hietalahden ranta and even though we bumped the ISO to 1000 on the 5DMKII, the images were sharp and had good contrast. The extender creates quite a bit of distortion on wide angles but it’s nice to see the lack of any dramatic distortion in these shots, something that is of great importance while shooting architectural detail.
