Just get the Tamron 70-300mm VC USD.
Better build
faster focusing
similar optics
lower cost

Canon isn't the only option.

400mm f2.8 OS - keep it under $3k. ::)

Since their current 300mm f2.8 is already 3.4K  a 400mm f2.8 is likely to be closer to 6K.  It would still be half the price of a Canon.

+1 on the Tokina 16-28mm.  That's what I got for my 5D3

You need to dig in the LensRentals blog, but Roger  provides great information based on multiple copies of the lenses.

All serious photographers need the 24-70ii and the 70-200ii in their kit!

All serious photographers with deep wallets that is.... Or are you not a serious photographer without these lenses?  :P

Serious photographers use primes  ;D

If you can get a high enough shutter speed with the 400/5.6, that's sharper than the 300/4.  Both are very slightly sharper than the 100-400, but there is copy variation to consider, so you may find some 100-400s that best the 400/5.6.  The 70-300L is sharper than all three.

The superteles are on a different class, for IQ and cost. My 600/4L IS II delivers substantially better IQ than my 100-400L, my 70-300L, or the 300/4L IS that I used to own.

+1  My 500mm f4L II has much better IQ than my 400mm f5.6L.   The 400mm f5.6L does play well with the 1.4x III on the 5D3   and with the Kenko DGX 300 1.4x on a Rebel.  The 100-400mm and extenders are much more hit and miss.

It WOULD be nice to start seeing better kit lenses.  I've always thought that the 15-85 would have made a great kit lens for the 60D/7D.  Yes, the kits would be more expensive, but as the lens would be higher production numbers, the prices would eventually come down.

15-85mm is sold in a kit with the 7D.  I got my 15-85mm as a white box  from someones kit.

Ah, since we're on the topic here's one I shot in April I thought was a lesser yellowlegs but I'm being told it's not.  Any idea?

It's a fair sized bird maybe about the size of a Canadian robin.


I'd go with solitary sandpiper as well.

You should take a look at the Tamron 300mm USD VC.  It is in your price range.

A couple from the last few days

don't have your specific equipment, but  I've used a kenko 300 dgx 1.4x converter on a 5D3 with  my 400mm f5.6L with no problems.  Before and after the firmware upgrade.
