This revolutionary and versatile wildlife lens has been released. I have taken delivery now and have written a preliminary review of this production lens. Once I have put it through a few wildlife photo shoots, I will write a more detailed review. This lens is a wildlife photographer's dream when used with the EOS-1D X camera. Take a look at my review below. Keep checking back. MichaelDanielHo.com
Canon EF 200-400mm f/4L IS USM Extender 1.4x Lens Review
I do recognize that this is the most versatile lens and waited for it for years resisting the temptation to move to Nikon for its 200-400 mm. But the sharpness issue was a big disappointment. I will give it another try; perhaps the lens I got was not sharp.
Hi Edward. I have just returned from a Arctic photo shoot in Svalbard. The weather was bad, many foggy days and the wildlife quite far. I brought the EOS-1D X, EF 200-400mm f/4 and EF 70-200mm f/2.8 In retrospect, I should have brought the EF 500mm f/4 to give me a bit more range but the lens works well. Some images are not as sharp as I hoped but then I was handholding the combo in a zodiac.
Just came back from a wildlife photo shoot in the Pantanal, Brazil. The abundant wildlife include Jaguars, Caimans, Giant Anteaters, many species of birds, etc. Brought the EOS-1D X and EOS-1D Mk IV plus the EF 200-400mm f/4L and EF 100-400mm f/4.5-5.6L IS lens. The EOS-1D X and EF 200-400mm f/4L combo worked like a charm again especially under high ISO condition, even when photographing moving wildlife. The itinerant Jaguar was photographed at dusk with ISO 5000 at f/4 and 400mm from a small, moving boat. Visit my website to see more wildlife photos.
