Excellent shots once more Edward
Silly question by the way, but does the camera go back to the default f-stop when you switch off the converter on the 200-400?
And for you in the US who consider this lens to be expensive, it's $17500 here in Sweden, just one 1DX difference :/
Hi Darlip, Thanks.
Yes, one of the areas I liked so much about this Lens was the ability to set the Camera @ f/4, Zoom out to 400, engage the 1.4x Converter, immediately goes to 560 @ f/5.6, then Back Button Focus on the subject, and start to follow the Animal back towards yourself, once the Animal fills the frame at 560, flip the converter out, immediately back to 400 @ f/4, don't touch a thing and the Focus stays locked on, then Zoom all the way back to 200.
The ability to Hold Focus through all this was amazing, I don't think I had a situation, where the Animal remained in site, where I needed to re acquire focus, the exception being the Cheetah Kills, the Lens/Camera was amazing at Holding Focus @ + 80KPH, except where the Cheetah went completely behind High Grass or Bushes, I then needed to quickly re acquire focus, and as you know, with Cheetahs at + 80KPH that's pretty well a "Too Late" scenario, Tall Grass, hate the stuff.
I set the Lens on this trip against the 400f/2.8 which I think is also an amazing Lens, but I also have the 300f/2.8 and it all becomes a bit too much to consider when you throw in the 600f/4 as well, so although I think the 400f/2.8 is a great Lens, I've off loaded it to a friend of mine in South Africa where like Sweden, the prices are at least 20% higher, so I ended up getting what I paid for it a year ago and my friend got a 25% discount, win win all round, and I keep the 300f/2.8 for those early Dawn, late Dusk shots.
The value of the Zoom cant be discounted for Wildlife, I always liked the Nikon 200-400f/4, although I still feel it's weak at 400, but on this recent shoot, a Pro Photographer friend of mine was shooting his 200-400f/4 and just couldn't stop drooling over the Canon 200-400f/4 with the converter, he also was trying out the New Nikon 80-400, seems a reasonable Lens as well, so I hope that Canon get the New Version of the 100-400 out soon, not that I will be a buyer, but it will be the go to Lens for Wildlife if you don't want to spend the Money on the 200-400f/4. I think Price for this Lens is the only downside, but for myself I couldn't be happier with the Image Quality coming from the Lens, one other minor point, the Lens in Low light does not Lock Focus as quickly as the 400f/2.8, understandable when you consider one Lens is locking initial focus at f/4 while the other is locking focus at f/2.8, it is something I noticed, but probably only because I was shooting both Lenses alongside each other.
I'm not sure wether or not the Lens initially focusses at f/4 or f/5.6 when the Converter is engaged, this is a little too technical for me, but a question someone like Nuero or East Wind could likely answer.
