Only if he insists on that being the only right way of doing it.

You're doing it too.

No it isn't!
Remember I have already stated I owned Sigma 150-600 and sold it after one use because it was so weak. Having said that there are plenty of others that also say the same as me, the 100-400 MkII cropped is every bit as good as the third party lenses at longer focal lengths.

I'm not saying 70-300L is a bad lens, I just think it is not a travel-friendly tool for non-photography-oriented trips.

No, the opposing argument is: we actually own and use these lenses and our real world experience conflicts with your imaginary scenarios. The bag discussion is just one aspect and it's a legitimate concern, but you are so invested in your own opinion that you have no interest in learning from the experience of others.

Really? I thought that you only use what fits in your bag. I'm confused![]()

And yet, there are people like me who own the 100-400 and the 150-600 sigma and find that the sigma compares very favorably, especially if you are using the 100-400 with a 1.4 extender. Blanket statements based on one use by one person can't be reliably extrapolated to every situation. Reviews by Tony Northrop should never be extrapolated to anything as far as I'm concerned.
privatebydesign said:Which begs the question I have asked, if the Canon 100-400 MkII cropped is in the same resolution league as the third party 600's at 600, what incentive is there for Canon to make another lens to fit in this small sales niche? We know (those that are not in denial) that Canon will not make an f6.3 max aperture lens, so they are effectively limited to a 500mm f5.6, and I just don't see them thinking this is a big enough market to make that when the 100-400 MkII is so good.
privatebydesign said:Just mulling it over, how about a long overdue upgrade of the awesome but dated 400 f5.6, a very high resolution 500mm f5.6 IS prime?
Now that I can see some logic in. Much smaller and cheaper than the 500mm f4, massive upgrade from the 400 f5.6 non IS. Price that at $2,999 or $3,499 at launch and I can see that selling well and fitting in the Canon lens portfolio without hitting other lens sales.

500 F5.6 IS would be nice but nearly everything is moving towards zooms.
Waiting for the 600 F4 DO. If I am very very good, perhaps the Canon Santa will develop one for me

Agreed, so why is Alan so anti my supported comments?
Normally I'd agree with you about Mr Northrop too, but he supports his assertion with actual images and confirms his was a blind test (though didn't give the details of the methodology).
Besides, I am not the one who has ever said there is a vast difference between the two options, I merely pointed out that there is empirical evidence from at least two on line testers that support my personal findings that a cropped Canon 100-400 MkII resolves as well as a Tamron/Sigma 150-600 at 600. Even Northrup points out the differences are small and a few steps closer would negate any real differences between the various lenses, and the LensRentals test Alan points to (that only tested to 400mm so is practically irrelevant) comes to the conclusion that "Canon’s 100-400 IS II is, from an MTF standpoint, the best zoom at 400mm".
Which begs the question I have asked, if the Canon 100-400 MkII cropped is in the same resolution league as the third party 600's at 600, what incentive is there for Canon to make another lens to fit in this small sales niche? We know (those that are not in denial) that Canon will not make an f6.3 max aperture lens, so they are effectively limited to a 500mm f5.6, and I just don't see them thinking this is a big enough market to make that when the 100-400 MkII is so good.
AlanF said:I am indeed anti your comments because they make a sweeping generalization based on selected examples and ignore evidence that doesn't fit. Your argument is:
"My Sigma 150-600mm C is weak and others say the same. Therefore, all such lenses are weak and a Canon 100-400mm II at 400mm cropped is as good as the Sigma at 600mm".
But, my Sigma is not weak, neither is unfocused's or many others'. The logical reasoning should be:
"My Sigma 150-600mm C is weak and others say the same. But some others have copies of the Sigma that are good. Therefore, some such lenses are weak and a Canon 100-400mm II at 400mm cropped is as good as those Sigmas at 600mm but other copies of the Sigma have better resolution than the 400mm Canon cropped".
I have the good fortune to own the Canon 100-400mm II as well as the 300mm/2.8II and 400mm DO II, and I am satisfied to use my copy of the Sigma, which I tested before buying from my local dealer. It's much better than my previous Tamron - it's all down to copy variation in these cheaper zooms.
