=Cap'n Fishy;15403494]I love my 100-400mm. I mostly use it on fishing trips and I occasionally cover pheasant shoots. At both of these it is on about 50% of the time. I've used it on a 40D, a 7D and now on a 5DIII and it has been a great performer on all 3.


Fishy action on Orkney...

The Nazca Booby is a Pacific bird, but is in the same family as the Gannet, which this one is.

Ha-ha! I just assumed it was a local nick-name for a gannet!

Wow... striking similarity! I'd never seen a Gannet before. Thanks for the clarification.

And to add to the name confusion, in the Netherlands we call these Gannets "Jan van Gent". :)

The bird is, to be pedantic, the 'northern gannet', aka 'solan goose'. It's the largest sea bird in our waters, and about three quarters of the world's population live around our shores, with Scotland a stronghold for them. There is a volcanic plug in the Firth of Forth estuary - where I live - and it has many thousands of gannets nesting on it - though the ones I have photographed have all been off the west coast of Scotland. Here are some more photos...

Notice they have no external nostrils - an adaptation for diving into the water at 60 mph without driving water into your lungs! Their nostrils are inside their mouths!

By the by... regarding the slightly derogatory name for the lens I love :) - does it actually make a difference whether you push the dust in or screw the dust in?

I would have thought it was the distance screwed/pushed and the amount of pushing/screwing that mattered, rather than the amount of rotation, vs lack of rotation applied while doing it?

I accept that in the case of the 100-400 there is quite a bit of distance involved, regardless.

(I realise that taken out of context that second paragraph sounds a bit dodgy! :oops:)

I would agree that the distance and inside diameter that determines the volume of air that comes into a zoom lens, so in that respect an equal volume zoom is an equal volume zoom is an equal volume zoom... There may be a difference in speed between push/pull and rotation that may change rate at which the air can enter. But it should still be the same amount of air.

Lens is that good it can make an ugly bird look good.
OK, so maybe it didn't work out that way with this shot.

I've posted this else where on this forum, but I think it should be here also. Once you get to know this lens, it is very capable (in my opinion) of producing memorable results.
