I bet the majority of us posting here are middle aged men. The white versions of cameras are mainly bought by women and the EOS 100D / SL1 is definately aimed at the female market as much as men.

You may be right; but if so, is it insulting or just realistic that the only white lenses are the 40mm and the 18-55mm kit zoom?  (As someone pointed out, the white Ls aren't white at all but a nasty orthopedic-shoe-beige.)

Here we see the defensive comments and a retreat to the trenches of the intangibles like bokeh (which is not clearly different in any sample shot I have seen anyone point to specifically) and creaminess [...].

Your overall point re pro-Canon bias may have more than a hint of truth about it, but I disagree with your implication that "intangibles like bokeh" don't matter (at least, I assume that's what you mean by "retreat to the trenches").  Of course, bokeh/blur is a tricky issue for reviewers because it can't be measured in the same way that resolution/sharpness can, and while there's presumably no debate whether one image is sharper than another, there may well be disagreement over which has better bokeh (and, of course, whether it matters in the first place).  But the fact that it can't be measured doesn't mean it's "intangible" - you see blur just as you see sharpness - and whether one image is "clearly different" from another is also subjective (in the 1.8 vs 1.4 comparison someone posted earlier to show that there was almost no difference, the difference seemed quite obvious to me and I had no difficulty at all in forming a preference).  And for some people a lens's bokeh/blur properties may trump other considerations. 

That said, for all I know the Sigma may have better bokeh than the Canon (unlikely though that may seem), just as the Sigma 35 1.4 seems to have better bokeh than the Canon 35 1.4 (at least as per Brian's comparison at the digital picture.).

Higher quality lenses also require a higher quality review(er). Just putting it on your camera and going outside and shooting some objects and posting centre crops doesn't cut it.

That's true of all lenses, of course.  But I don't think test chart comparisons are terribly helpful either.  What I would rather see - and which Brian will surely do when his review shows up; it's one of the most useful aspects of his reviews - is comparisons of photos of actual subjects of various sorts: portraits, buildings, landscapes, etc. 
I suspect the Sigma will prove to be a superb lens, and wouldn't be at all surprised if in may ways it beats the 50L - though if I used a 50mm lens to take portraits I would be far more interested in which has better bokeh than which shows the most clinical detail. 

(Personally, I have no stake in this particular debate - if I want crazy sharpness from a 50mm-ish lens, I suspect that my Sony/Zeiss 55mm 1.8/Sony A7r combination is at least as sharp as the Sigma would be on any current Canon body, while weighing less than the Sigma lens alone, and if I want a blur-fest from a 50mm-ish lens I'll use my manual Canon 55mm 1.2 on the Sony.)

He hasn't yet reviewed its big brother, the Sigma 180mm 2.8 OS, which evidently knocked the socks off the hard-to-please lenstip reviewer:


Has anyone reading this tried that one?

I'm about to put my 50L on Ebay.... and it has nothing to do with this new 50mm Art.

I took my kids to Flower Field in Carlsbad yesterday. I carried A7r + FE 55mm. With Eye-focus feature in A7r, compose the shot is so easy. At wide open, I couldn't miss a shot. However, the Bokeh is not smooth as my 50L.

Bottom line is, I'm willing to trade that bokeh for light weight ;)

I suspect that for most real world use the differences between the new Sigma and the FE 55mm are trivial, far less than the difference in weight and size; it's nice to be able to carry around a FF camera and two primes in a small bag whose weight is negligible.  The FE 55 is so sharp on my A7r it's hard to imagine I would appreciate something even sharper, and if I want more dreamy blur I can use my old manual Canon 55 1.2.  I may end up buying the Sigma in a Canon mount, especially if reviews appear showing comparison shots involving something other than test screens and the like - though the Sigma on a current Canon FF sensor may not look any sharper, if at all, than the FE 55 on an A7r anyway, and the more I get used to the light weight of my Sony and M43 mirrorless gear the harder it is to return to my vastly heavier FF Canon gear, much as I like it.  I wonder if Sigma would ever be interested in making longer and wider primes (or even zooms) in Sony's FE mount....

Maybe I didn't read his review carefully enough, in which case apologies in advance, but where in his review does he say that sharpness is a bad thing, that amateurs only care about sharpness, that pros don't care about sharpness,

He doesn't "say" sharpness is a bad thing, but he "holds" it as a negative factor, because he associates sharpness with amateurs, instead of praising it as a feature.

Warning 1: Image sharpness depends more on you than your lens.
Warning 2: Lens sharpness doesn't mean much to good photographers.
Amateurs waste too much time worrying about lens sharpness, and since this lens is designed for amateurs, it's super sharp.


Why do you feel the need to start an argument by claiming "I am making things up"? You could have nicely asked for a clarification. Because online posts are anonymous, we don't need to be polite and courteous to each other, is that it?

OK, apologies for the tone - I perhaps should have said that your interpretation of his comments on sharpness is not persuasive.  They don't read like that in isolation, and you will find language to that effect in every lens review he writes (every one I've read, at any rate), regardless of who makes the lens, and regardless of whether he likes it, including all his Nikon and Canon favorites.  It seems to be part of his review template.  Nowhere does he say that sharpness is a negative factor - it's part of his insistence that sharpness is overrated and that sharpness also depends on factors beyond the physical properties of a lens.


When the 5 year old turns 21 in 16 years time, what would you rather have?
4k video or 1080p video of the birthday?

If that's the sort of thing you're going to film with this camera, you should note that, according to sonyalpharumors: "The only bad news is that it doesn’t record 4K on SD card. You will have to use an external recorder."  How many people are interested in doing that?  (It's not an issue for me as I never shoot videos, unless I hit the wrong button by mistake!)   

The low light possibilities sound intriguing, though - so far there are precisely two Sony FE lenses that I want (and own), so I guess they could have a body each.  Sony's body:lens ratio seems a tad off....

Hope the "S" stands for stabilised :)

It evidently stands for "sensitivity" (honest - you can read all the details at sonyalpharumors), so please don't say mean things about it.

But not only the L fanboys are vehement against Sigmas and Tamrons. I was shocked how Ken Rockwell snubbed the excellent 18-35mm (even he had to agree it is optically superior) and advocated not in favor of an L but all the EF-S lenses! Of course, he recourses to simply lying when comparing the 35A's build quality to the 35L's. Without batting an eyelid, he says the Canon has a metallic body and the Sigma has a cheap plastic body.
And in both Sigma reviews he holds being sharp as a bad thing, saying these are sharp because they are built for amateurs, who care only about sharpness! Lol! So to build a lens for pros, Canon and Nikon deliberately build non-sharp lenses.

Rockwell says enough silly things (often contradicting himself) that you don't need to make stuff up to criticize him.  Maybe I didn't read his review carefully enough, in which case apologies in advance, but where in his review does he say that sharpness is a bad thing, that amateurs only care about sharpness, that pros don't care about sharpness, or say anything negative about the lens's optical performance aside from "significant axial chromatic aberration at close distances" at f1.8? Rather, he states that "optically this lens is extraordinary" and that "if you don't mind the weight and don't worry about the future ... [it] works fantastically well today."  He does make his usual comment about many people worrying to much about sharpness (he may have a point), but the reasons he gives for not wanting one himself are its size and weight, lack of IS, his fondness for the Nikon 35mm DX, and worries about long term performance and compatibility with future camera bodies.   


Test results demonstrate that Canon  EF24-70mm f/2.8 M2 is much superior to Sony Zeiss 24-70 f/4 OSS in resolution and color reproduction and overall image quality .  Especially this is noticable at 70mm focal length .
From test pictures it is obvious that even on 36mpx   Sony a7R body  Canon  EF24-70mm f/2.8 M2 still does not reach it's limit in resolution power.  This combination is perfect one when focus speed is not important.
On the other end  Sony a7R with  Sony Zeiss 24-70 f/4 OSS  is a fairly good combination as general purpose  walk-around point and shoot camera.

I also tested Canon TSE 17  on a7R and image quality , color rendering and resulution is also of top possible quality. 
It seems that Canon TSE 17 the same as Canon  EF24-70mm f/2.8 M2 still does not reach it's resolution power limit on a7R
Canon TSE 17  on Sony  a7R  looks as  perfect  combination for Architecture and Landscape photograpy.

Sony/Zeiss don't seem to have figured out how to make a first rate zoom for their A7s yet.  If you compared the Sony/Zeiss 55mm 1.8 you would have seen a significant difference too (the 35mm 2.8 as well, probably).  But you don't need to attach Canon lens as new/expensive as the Canon 24-70II - you can get fantastic images from many much less expensive Canon lenses on the A7r, even such bargains as the 40mm pancake and 85mm 1.8 - if nothing else, the A7r shows just how good many Canon lenses are!

I am learning to shoot large format 4 x 5 (B&W), and am awaiting my first photo encounter with a high-end Canon or Nikon user. Great opportunity for reverse snobbery - film, old format, old bellows camera, really old (circa 1960) single-coated lens.

Good for you!  A couple of years ago I came across someone photographing autumn leaves behind some historic buildings here in Philadelphia using a similar camera on a huge wooden tripod - looked marvelous.

Although #5, P mode... I sorta agree if you have anything above a 70D or so. At least learn enough to use Av or Tv if you're going to spend that much money. Rebel or other entry-level SLR/ILC, sure, ok if you just want a more capable camera than a phone or bottom level P&S.
If someone wants to own a 1DX or 5D MK III and use it in P or Auto mode, why not, its their their money and their choice ... when more people buy high end DSLR's, its better for the manufacturer and the customer - they get volumes and we get lower prices.

Quite so.  Aside from that, the advantages of Av etc. apply just as much to Rebels, and the advantages of FF - esp. low noise - apply regardless of whether you use Av or P etc.; and while you can learn how to use these various controls on a Rebel, it's actually easier to do so on more advanced cameras as they make it easier to use them - easier still if you have a camera with an EVF that lets you see the effect of the changes you make as you look through the viewfinder - and provide a better viewfinder to boot.  I dare say that, for many, a fancy camera is overkill (esp. if all you're going to do with the results is post them on, say, facebook), but that's their loss, not anyone else's.

The performance of the A6000 looks awesome, and the price point is very good...Sony is bringing it's A game!  This looks like a great little travel camera for work trips, and I think I'll be purchasing one.

Help me to understand why Canon/Nikon full frame cameras don't offer the same wide area coverage of focus points as the Sony A6000???

Maybe I'm wrong, but perhaps this is a mirrorless vs (d)slr thing?  Every mirrorless camera I've used has a wide area of coverage, whether FF (Sony), APS-C (Fuji) or Micro 4/3 (Olympus, Panasonic), while every dslr I've used, FF or APS-C, has the focus points lumped in the middle, regardless of how many of them there are (there's better coverage with APS-C, but that seems to merely reflect the crop factor - the FF Nikon D600 has the same focus system, more or less, as the APS-C D7000, but because the sensor is so much smaller on the D7000 the focus points cover more of the sensor).  This is one reason why I prefer mirrorless.

It's becoming harder to convince my friends that buying only Canon gear is the right thing to do.

Sigma have put out some amazing lenses in the last two years and Canon's only memorable release is the Canon EF 24-70mm F/2.8 L II.

I guess "memorable" is subjective, but over the past couple of years Canon has released, in addition to the lens you mentioned, the 24-70 f4, 24IS, 28IS, 35IS, 40mm pancake, and 200-400L, all of which are first rate regardless of whether one may actually want any of them.
