Would like to enquire whether a 5 year old 400 mm f/2.8 L make I (not II) which is in excellent condition is a good deal at 4000 euro, and what is its performance with a 2x TC III on a 1DX, whether images are still sharp.
That sounds very cheap to me, the cheapest 300 f/2.8 I've seen secondhand in the UK in the last few months was 3300. I can only compare with my 300 f/3.8 with a 2x extender. I've only used the combination a few times, the IQ is definitely reduced, but there is still some sharpness there. It ultimately depends on usage. For prints it should be fine, but I wouldn't want to try using the images commecially (from my 7D anyway). That said, I have never got around to microadjusting and the 1D X IQ should be better also.charlesa said:Would like to enquire whether a 5 year old 400 mm f/2.8 L make I (not II) which is in excellent condition is a good deal at 4000 euro, and what is its performance with a 2x TC III on a 1DX, whether images are still sharp.

Search flickr .... there is a "group" with really sharp shots there.

Unless I am reading the 2x MkIII manual (http://gdlp01.c-wss.com/gds/8/0300004658/01/extender-ef-2x-iii-en.pdf) wrong, it says "Using an Extender with this lens may result in incorrect autofocus." The 2x MkII manual (http://gdlp01.c-wss.com/gds/0/0300003490/01/extenderef2xii-en.pdf) contains no such warning.

eli72,
You are absolutely correct in the information you posted. Thanks.
4000 euro seems a good deal to me. perhaps too good. just make sure you test the lens thoroughly, check if the IS still works etc. and you will have a really great lens for a relatively cheap price!charlesa said:Would like to enquire whether a 5 year old 400 mm f/2.8 L make I (not II) which is in excellent condition is a good deal at 4000 euro, and what is its performance with a 2x TC III on a 1DX, whether images are still sharp.

true, but as the OP stated it's a 5 year old 400mm. so i guess it's pretty save to assume he's talking about the EF 400mm f/2.8L IS USM. the 400 f/2.8 non-IS lenses are from 1991 (mk. I) and 1996 (mk. II).GMCPhotographics said:There's a number of versions of the Canon 400mm about. The current model is the ef 400mm f2.8 L IS mkII. It's the best of the breed, and the lightests. It has the newest Image Stabiliser.
The old version was the ef 400mm f2.8 L IS and this is optically equal to the current mk II version, but it's a big and heavy beast. Both of these lenses are listed on The Digital Picture lens test web site and can be compared. This lens has an Image Stabiliser.
The previous version to this was the ef 400mm f2.8 L mk II. This lens doesn't have an image stabiliser and is heaver than the newer versions. It has a Flourite lens element that puts it's IQ into the same league as the latter two lenses. This is an optical peach (as are the other two lenses) but it is a heavy beast and no IS. It's min focus distance isn't as close either.
The oldest version of this lens is the ef 400mm f2.8 L. This lens is the oldest and heaviest 400mm in the Canon EF linage
