Almost complete, just considering a swap out for a few.That's a great set and I guess the 15 fisheye isn't used much anyone with the 8-15...and I can see the 35 f/2 IS over the 1.4 for most uses. I see we have many of the same lenses and I can definitely recommend the 300 2.8 IS II as an upgrade to your 400 DO. It's an amazing and versatile lens when you throw in the extenders!

Currently trying to sell the 15 fish
Want to swap 400/4 DO for either the 200/2 or 300/2.8ii
Already swapped 35L for 35/2 IS
That's what I've been reading re the 300ii for a good while now and I've just been lazy to really try to offload the 400. Not the easiest lens to sell locally. I have read and seen nothing but good re extenders and the 300. I'm not happy with the 2xiii on the 70-200 until f8 and I've read that there is apparently only a negligible hit to IQ with the 300 + 2x at 5.6 (or any other aperture for that matter) which is astonishing.
The 35 swap out has worked out well since the former was too close to 24 and 50 (and no IS) for me to justify keeping it. The 35/2 IS is a great all around lens for photo/video across both of my bodies.
And yes, the 15 desperately needs to go as it has seen zero action since the zoom acquisition.
