Hi reading with great interest Dino F's thread on the 300mm F4 prime and a 1.4TC compared to a 400 F5.6 as below : great thread by the way :thumbs:

I don't think I saw the answer (appologies if so), but does the IS still work on the 300 F4 if you are using the 1.4 TC ??

Cheers :thumbs:

Yes, it does on mine.

Hi Andy,
My 300 is non IS, but I'm almost certain a IS version still works with a 1.4x..

Then there's the debate about... Do you need IS when shooting at 1/800th + sec?? :thinking:;)
Good for shooting the props at slower speeds, but for fast jets??

Some people also claim ''it slows down the AF''? and have the IS turned off..

[mho]

yes it does

Thanks for that Neil

Food for thought :)

I'm dropping subtle hints at home as father days approaching :lol::lol::lol:

Some? ... You can actually hear the IS kicking into action while you wait for focus... it surely does slow AF down using IS
