Does a Sigma 150-600 replace 400 5.6L?

Have you tried any/all with a 1.4x III extender?

I had many Sigma lenses with focus issues. It was years ago, before they came out with the Art, Sports and Comtemporary series. It has nothing to do with luck, or unluck when you call Sigma and ask for a focus adjustment, and they told me that it was my cameras fault. My answer was that my other 5 Canon lenses focus fine, they still insisted it was my cameras fault. They wanted my camera too, but i denied, because i feared they would adjust my body to their lenses, and my Canon lenses would then misfocus.
It has nothing to do with luck, or unluck when you sent in a Sigma 500 f4.5 for repair (bought it used, but it was soft wide open). Sigma germany told me the lens was out of spec, but had to be sent to Japan for repair, Sigma Japan told me the lens was within spec. I can proof this, i still have the papers.
I had more issues, which i dont remember anymore. Now, with the A, S, and C series you can adjust the lenses yourself, with the dock. Thats what Sigma says. I say its a ripoff, i pay money, and get a lens that doesnt focus right, then i have to pay even more money for the dock, and make the adjust work for them. They get even more money, and have less work, winwin for them. But not with me. I dont fall for that marketing trick.
Since then Sigma is dead to me. And there is nothing they can do to change that.
Well that explains a lot.
Technically they're probably right, a lot of responsibility in this does sit with the camera, but this was discussed much more thoroughly in another thread and Idon't think sending in the camera would habe helped (I don't think Sigma ever had that level of access in the firmware to deal with the real issues).
Actually, there is added value beyond that in speed and focal range adjustments and being able to easily update the firmware is very nice. I think perhaps it was Metz that pioneered this on their flashes?
That may be, but the 180 EX also dates to the pre Art series era. It is an EX series lens and is one of the best focusing lenses I have ever used. What's the catch? That it costs more than even the first party macros.
If you're set in your ways, then you're set it them, but please do realize that not everyone is looking for outdated advice. Brands do change over time and can be either better or worse than before. I understand that Sigma used to have quite a lot more issues when they were run as purely a budget brand. Not to say they have none now, but it is much better than before.

I dont care about any other dock features. My Canon lenses never needed a firmware update. One day Sigma will not update the firmware anymore, it happened in the past, and then you cant use those lenses on your new camera.
They have improved the optics and build quality, but the electronics remain the same, with random focus generator. They have no clue how Canon AF works. What good is the sharpest lens, if the focus if off ? Recently they built fast lenses, where good focus is critical, because of thin DOF. The 18-35 f1.8 may be a sharp lens, but the focus is all over the place. I bet that if i would buy a Sigma lens right now, it would have focus issues. I wouldnt buy that dock, because i dont want to give them even more money, and take the adjustment work off their back.
Maybe you don't intend to, but any newcomer reading many of your comments would think they are fit only for the bin, I'm not asking you to buy them.
Your Zeiss auto focuses on your Canon?! Where did you get them, take my money

In my opinion Canon could do more to make sure third party lenses dont work with their cameras. If i were Canon, i would.
Thats a very stupid comparison. Sigma makes "compatible" lenses for Canon. Canon does not make lenses for Samsung.
Maybe Sigma has improved, maybe not. I dont give a sh*t.

There are issues, and newcomers need to know that. Then they can decide whether they want to take the risk, or not. The risk might be low, or not, i dont know. But its there.
Of course they could, I stated in several other threads that they don't make the protocol very difficult. But I also stated that I don't believe the protocol nor the reverse engineering are the issue.
it was a bad stretch, but is relevant to my own case.
Well I'm hitting one of two today.
Then should I go around giving dire warnings about Canon camerasbecause the mirror could come loose? I think it is about time that we try to really quantity this frequency, because that is the crucial stat here. ... Lens Rentals? Please. ^_^ Looking your way.

1) Sigma has posted a 5% sales growth according to this article:
http://www.straitstimes.com/tech/cameras/sigma-lenses-riding-the-headwinds-in-the-industry
Is this really likely, if, as you suggest, customers have a "high probability of frustration"?
2) As posted elsewhere, you have a high regard for Zeiss lenses and yet you couldn't tell the difference between the Sigma 180 macro and a Zeiss lens when challenged to do so. The complaints about Sigma tend to concern autofocus - one assumes that your Zeiss lenses are manual focus anyway, so how does this make sense?
3) As I also pointed out previously, not so long ago, the homepage of this site carried a fantastic, prize-winning moon photo taken by a very talented photographer using the 150-600 Contemporary zoom. Surely all that matters is results, and these were shown for all to see.
In my opinion, these points render your criticism irrational and serve to make your comments sound unthinking at best and hysterical at worst.
If you disagree, by all means post a cogent reply to each of the above points in turn.

All of the above.
Range: Yes
General versatility: Yes
Stabilisation: YESSSSS
BIF: Yes
Weight: NOOOO
Sharpness: Yes & No
Compatibility: Probably
Prejudices: YESSSSS
For all the nay sayers rent it, try it, abandon it.
