The dock makes sense for the 120-300/2.8 OS S, but it should have been unnecessary for their other lenses. Fixing their lack of ability to make lenses that can focus on Canon and Nikon cameras should be their responsibility, not their customers'.

I really don't care what lens other people purchase...it's their money and their choice. I was addressing this "risk" myth out there when purchasing a Sigma lens. There is zero risk...if the lens does not work properly you can either exchange the lens where you purchased it or you can send it to Sigma to get it fixed for up to 6 years after you purchase it. I don't see any risk at all...trying to clear up all the hyperbole that seems to swirl around the Internet.

And why is it that Canon put micro adjust into their cameras?

The two issues aren't related- not really. Canon's MA function accounts for minor variation, not the kind of issues that Sigma (and other make) lenses seem to regularly exhibit. Accuracy is one thing, consistency is another; and the dock doesn't fix that automatically either.

They may not have come out with a 24-70OS... yet, but they did release a 17-70 OS 2.8-4 that I bought on a whim, and it totally replaced my 24-70 altogether. It may not be 2.8 at both ends, but the OS makes up for it. And when I want shallow depth of field with no hiccups, I'm usually shooting with a 50mm 1.4 or an 85mm 1.8. I will rave and rave about that lens. It's sharp all the way across the board.

Perhaps the Canon 24-105 4L proved too be a little too popular and Sigma wants a piece of that big pie. A 24-70 2.8 OS would have a much smaller market due to cost and weight. Nevertheless the 24-105L is heavy enough at 670g and on the edge for me as a travel and walk around lens. A Sigma at 885g is over the top. I'd rather pay extra for a lighter L zoom like the 24-70 4L IS and hike all day...

The dock and MFA help with accuracy, which can potentially be extremely far off. There is no reason that only one sigma would need it and not others.

Precision is something else as you say, but that isn't related to what you first wrote (which is not to say that Sigma have not suffered from precision issues, at least the last time I used them, but that was some years ago).

Maybe it was just yet another bad rumor and faked image then. A good one, considering that the Sigma webmasters got confused themselves for a day.

Good point. I had forgotten other brands than Canon existed . I guess it looks good for Nikon for sure, at the least.
Maybe Sony too??

Oh come, it's not that bad, only 81g more than the 24-70 f/2.8 II. How much is 81g?

( )

(Man, this thing weighs like twice as much and is like twice the size of the 24-70 f/4 IS. OK not quite but 600g vs 885g.)

(Wow and people have been talking about Sigma 24-70 f/2 rumors, what would that be 95mm front element and 4780g?)

(It could still be good for Canon users as the 24-105L sure ain't all that, but man it weighs more than the 24-70 II and the MTF hint it might not be as good as the 24-70 f/4 IS nevermind the 24-70 II and the 24-105 can be had for lke only $600 these days so.... it better be a lot better than their MTF hint at and be a complete match for 24-70 f/4 IS IQ and easily beat the 24-105L and not cost more than $1000 street.)

If you believe this is the reason you've never dealt with OEM lenses before. This is simply a smart move that ALL makers should do.

sigma needs to make an ultrawide better. The 12-24 isn't terrible but def is as good as what they're making now..

This lens should be interesting if it's up to the standard of their primes

Not the sole reason but it removes the stigma. Sure all should do it but it cuts into profits so it will be a slow rollout for all.

My OEM Canon lenses perform VERY consistently. The level of PRECISION with them is impressive. Once I use the in-body micro-adjust, they are both PRECISE and ACCURATE, at all focal lengths and distances.

My experience with Sigma lenses has been, for the most part, not nearly as great. Not only have they been inaccurate right out of the gate, (which an in-body micro-adjust would fix) but they weren't precise either. No repeatability in the error of the AF. The USB Dock is a great idea in theory, but in practice even it couldn't properly account for the problems with my 35mm f/1.4. I guess the bright side is that, because this lens is only a moderately-fast f/4, some of the focus issues will be masked by the larger DOF.

I'll pass.

Sigma or Canon.

Someone needs to release a tack sharp UWA-zoom for Canon DSLR's.

Nikon has had theirs since 2007.

That's... pretty much what I'm thinking. Except that I don't have an S35/1.4A .

Though, I will happily admit, that if I did have one, and it did focus accurately and consistently, I would have been thrilled last weekend. The 50/1.4 USM is good when mated to the 6D, mind you, but across the field sharpness wide-open at a wider angle sure would have been useful.

Hell, I've wound up using my SY14/2.8 for this kind of stuff indoors- at least on the 6D I can crank the aperture down and set the focus to ~1m, and damn near everything near-field is in focus.

But a zoom- especially a stabilized zoom- would be really, really cool.

How many Sigma lenses have you seen that cost more than "the same Canon lens"

But just remember-- you've never actually used the Sigma 35mm f/1.4, and you're just a parrot!

For the most part the AF issues don't bother me too much up to a threshold. But in some lenses, AF is more important than other factors for me. We all have our specific wants and needs.
