Wonder if this lens will be eligible for Sigma's "mount conversion" service?

I'm surprised that so far nobody has said DxO's results are meaningless because they don't represent bokeh in their tests results anywhere! But at least the first post on this thread doesn't disappoint with the expected putting down of DxO.

When DxO get a Nikon mount copy of this lens, I think we'll see a much better representation of its capabilities. In at least one score, the "megapixel" thing, the scores are obviously limited to what Canon cameras can provide.

Compared to the 50/1.2L

Wow, that's about as cherry picked and biased a comparison as I've ever seen. Do you even try to be objective?

No honey, I don't. If I was objective then you'd have nothing to post about and then you'd get bored.

Lol. I was definitely thinking earlier, "Does this neuroanatomist guy do anything besides disparage and critique?" There's definitely a theme with him.

I just want Canon to come out with their IS version so the Tamron price comes down.

Why does everyone seem to think they're going to make a 135mm f/1.8?  And why does everyone think it's going to be a f/1.8 instead of f2?

Just cause there have been rumors about one in the past. Plus, with the fact that Sigma is the only company with a f/1.8  zoom in the market it would seem appropriate. But f/1.8 or f/2, I doesn't really matter that much to me; marginal difference to the final photo. I think a f2 OS is more likely all things considered. And $950 would be perfect for the sub-$1k theme Sigma might be starting.

That being said, people complaining about a little extra weight really need to grow a pair and hit the gym a little.  I work out regularly, and I've never had an issue handholding my 300mm 2.8 lens for a whole day whether it's my kids' sports or at the racetrack.  I have a 400mm 2.8 now, and I also do okay with that for several hours.  If it's a really long day, like an all day shoot, then it gets a little tiring, but nothing where I stop shooting.  To hear whining about "heavy" lenses, like this supposed lens, which would be about 2 pounds, is hilarious.  It's not an issue if you take care of your body and exercise a bit.  Do you realize how pathetic and weak you sound?  My wife takes care of our kids everyday.  Our infant can't even walk yet, and he weighs more than a Canon 800mm f/5.6.  She never complains.  I'm sure any mother would laugh at you people who complain how a new lens will be too heavy for all day use.

+ 10gazillion.

Well, there's around a 13 month separation between the game-changing release of the 35A and the equally game-changing release of the 50A (relevancy?). So which lens is slated for next year? I'm hoping for the 85, though I suspect it will be a 24. 135 f/2 anyone?

Who would have thought just a few short years ago, that Sigma would become the preeminent AF lens manufacturer? Certainly not me...

24mm f/1.4 next please. Not impressed with the SamRokin 24mm, and the Canon is ungodly expensive.

Wouldn't this be a nice Sigma Roadmap ;D

35mm f/1.4 Art - $899
50mm f/1.4 Art - $950
24mm f/1.4 Art - $950
85mm f/1.4 Art - $799
135mm f/1.8 OS Art - $950

At the current rate, my bag will have nothing but Sigma primes and Tamron Zooms lol. Although if a 24mm & 85mm continue on Sigma's new level of quality, by the time a stabilized 135mm f/1.8 is released it should be priced at $2,000. Not that I want to pay that much (and probably wouldn't), but I'd like to see the new Sigma quality truly recognized, if that make sense.

The issue has always been size and weight and it being usable over long periods of time for event photographers.

?????

I use a 70-200/2.8, as do many event photographers.  As long as it's on par with or smaller than that, why would this be an issue?

I hope the Sigma 24-70/2.0 OS is real.  I'd be more interested in that lens.

+1

The only time I see weight as a relevant consideration is if 1. You're traveling, or 2. You're shooting for personal reasons.

A Sigma 24-70 f2 OS would be amazing. With the way things are going lately it's not a stretch to image nothing but 3rd party lenses in my camera bag. That thought makes my wallet very happy.

I submitted my preorder on B&H 3 hours after they started taking them (so at like 3am EST). Think my spot in line is good enough to be fulfilled with the first shipment? I would think so, but I don't have any previous experience with preorders.

Here's what I've been waiting for - a 50L to 50A comparison from SLR Lounge

I think it's enough to convince me to cancel my pre-order.  The Sigma is sharper, but not shockingly so, and the Canon's bokeh is slightly better (IMHO).  The Canon also appears to have ever-so-slightly better contrast, while the Sigma has better CA control, but again, only by a hair.

The other thing I've learned is that you'll have buy the USB dock to enable full time manual focus (which I guess isn't standard for Sigmas).  That's crappy. 

The 50L has killer build quality and USM in a much smaller package and I don't think the Sigma is worth 950 of my dollars for such subtle differences at f/1.4 in what for me, is a portrait lens. 

I guess I can't cancel it till the 24th, so I'll keep my mind open until then, but I think I'm going to cancel and resume the 50L II vigil ;)


Here's a more scientific comparison of sharpness. Seems the Sigma vs Canon L decision is really sharpness vs. bokeh, respectfully. If I had a 50L I probably wouldn't sell, but since I don't, I'm still super excited about my preorder :)

More stuff:

CNet Review - love the lack of IS as a con ;D

Sample images (including full res) from Pop Photo

Pop Photo Review


are they getting misfocus at f/1.4? it looks a bit dreamy and soft like the canon 50 1.4 no?


CNET images are sharp, so I take it you're referring to popphoto? I do think that the shot of the tree was mis-focused, even stopped down it looks soft. But, did you check the other shots at full-res? Most 100% crops at f/1.4 (especially the first shot of the sunglasses) look way better than any Canon 50mm I've used. Anyway, I don't think popphoto set of images was "shot properly" for our scrutiny; a lot at ISO 1600 and unnecessarily overexposed.

I think if you look at samples from a wide variety of source, you'll see it's living up to the hype.

But the conclusion I've come to... is that Canon may cost more, but more often than not, it is well worth it. 

As long as Sigma has no choice but to reverse-engineer Canon's AF system, there always remain a chance that a Sigma lens may no longer work, or no longer work 100% (such as weird focus behavior in live view, etc, which I have experienced with some Sigma), with future Canon firmware updates or future Canon bodies in general.

Having dealt with Sigma service before with headaches abound, I can understand those who stick with the Canon brand.   


Yes, and any future malfunctions of 3rd party lenses are most likely deliberately caused by Canon in hopes of forcing brand-loyalty. Sigma knows this, and is the reason they offer the USB dock. So when your lenses all of a sudden have issues, complain to the responsible party, not Sigma.

Well, just pre-ordered mine. Didn't really have the money to spend, but whatever  ;D

Sony A7s. Confirmed 12mp Full Frame sensor and 4k video means 1:1 pixel use (no artifact/binning issues, more accurate color, etc.). Low light should be damn impressive too. Full announcement coming this Sunday (4/6) at NAB.

And unlike the GH4, a metabones adapter already exists that allows aperture control and IS for EF glass on E mount bodies.

I hope Canon is paying attention, beyond discounting the 1D-C.

Seriously considering jumping ship for the m4/3 system. Pan/Oly so far ahead of Canon on just about everything.

Troll much?  Regardless…bye.   ::)

I wonder if you can comprehend the irony.

Repulsed.

What this world really needs is yet another 50mil.. Don't think so, SamJunk is smarter than that.

Actually, the world does need a modern 50mm under $1,000 that's usable (for more than just portraits) at 1.4. If Sigma wasn't releasing a 50 of their own Samyang would stand to make a killing if it performs good wide open (i.e. on the same level as their 35mm and 85mm).
