Is the 400 Prime an "L" ?
It sure is!
Just checked ... Not much difference in price to be honest Pete,
WHE price's which are'nt alway's good ... There is just over £150 difference
with the Cashback on the 100-400,
100-400 = £989
400 Prime = £829
Decision's decision's lol,
Thank's Pete,
Tc,
John,
I guess that you mean 'sharpness of the optics' rather than final image. That is, IS will help eliminate slight movement and vibration and reduce the number of shots with softness introduced by technique, rather than make the glass itself resolve the light any better.
But at the same time I must admit, that when I am viewing Galleries in this forum - a lot of you do have excellent copies of the EF 100-400. Hard to tell any difference compared with the EF 400 f/5.6, if any in the field.
Not sure I follow you here John as the 400mm f5.6 prime is cheaper than the 100-400 zoomThank's Mark for the Link ... I'm definetly going to give it a read,
I am in the process of Buying my first "Good" lens ... Definetly an "L" but
i have no idea if it will be Prime or Zoom ... I'm thinking Zoom only due to
price to be honest, Thank's so much for the Info too,
Take care,
John,

Keith, the big unknown with trying the see the lens quality via web pics is that you dont know how much the image as been cropped. A very heavily cropped pic of a bird that was say, 40 meters away will hardly ever be a good as one taken from 7 or 8 metres away with any long lens. My best shots have always been when I have been fairly close to the bird (which is very rare).But to balance the argument, just today I've looked at some pictures on BF taken with the prime on a tripod and a beanbag which I'd have deleted out of hand if I'd taken them with my kit.
.
there's no definitive proof out there that the prime is routinely superior to the zoom - or of course, vice versa. One test swings one way, then another test redresses the balance.
So we should look at the bigger picture (no pun intended). If the sharpness of the two is close (and it is), then the other factors should be considered as part of the decision.
- the whole package needs to be considered, and I am in no doubt that as a package the zoom has a hell of a lot to offer.
PS Just for fun Keith, no offense intended |;| |;| |;|
This is one situation where the zoom offers a clear advantage as it allows you to alter the height of your table!
Also the stabilisation would help avoid spills!
I don't know if this is relevant here, but I'll chuck it in anyway.
There are shots I've taken with the 100-400 which stand up very well indeed to my prime (which is a 500/4). Not a great many, but a reasonable number. When everything is right, the zoom is as good as you could possibly want.
BUT if I look at the good shots I have which were taken when everything wasn't right - i.e., when the light wasn't what I'd really want, they are just about all taken with the prime.
This leads me to my own personal theory: that the zoom can be close enough to as good as the prime, but only when the light is really good. Once conditions deteriorate, all that extra glass takes its toll. I make the same comment about using teleconverters: you should only do it when you have light to burn.
Could this apply equally to the 100-400 vs 400/5.6 debate?
Also, having read so much interesting tripe on the interweb about varying quality of the 100-400, can I assume that some examples will and some won't take the weight or is it due to poor twist technique?
