Why you say 50mm 1.4 is a FF lens?? Just put it on a APS-C sensor..
it becames a 80 1.4!

No it doesn't. It still is a 50mm f/1.4. 50 mm is 50 mm is 50 mm and f/1.4 is f/1.3 is f/1.4.

However, the 1.6 crop image is equivalent to an 80mm f/2.2 on a full frame camera.

Sorry couldn't resist. I'd certainly buy one as it's been on my want list for a while. I think Canon's G9 might lose some sales, though consumers would no longer have to deal with the shutter latency in a G9. I agree... I think that would be a good lens for a third party vendor to make.

I have been wondering if Sigma will release more large aperture lenses. Im also curious to see if they update some of their lenses with OS, such as the 120-300 f/2.8 or the 100-300 f/4. Maybe their 70-200, or 300mm f/2.8

personally speaking, I plan on buying the 50mm f/1.4 once I can afford one, $500 is a lot of money when you are a student working for peanuts.

Sorry, I meant to say 1/2 stop.

Again, I can't imagine why anyone would want to spend all that money for only 1/2 stop.

Don't keep your hopes up. The very last lens they've implemented, the 50mm f/1.4, looks good optically but is plagued by AF issues.

In my experience, there are no longer any difference worth mentioning
between Sigma and Canon with regards to QC. They are both good, still
none are perfect.

All my 5 Sigmas AF perfectly streight out of the box. Some of them
makes more noise and take a split second longer than a Canon with
USM, but who cares, at 1/2 to 1/3 the price. Now that Sigma is
perfectly able to produce optically superior lenses, Canon should
really start to sweat.

Just wait until Sigma comes with a 85mm 1.4 EX with fast ring type
HSM, maybe even OS since it's a short telelens, FTM and every bit as
good glass as the Canons:-)

well, i know im waiting for a 80mm 1.4 so that when i "eventually" go FF ill have the same equiv as what ive got now with my 50 mil now...
LOVE that focal length :D

No more so than the 50L. It also seems that the problems was only in the first samples, and are fixed now. The 50L is still not fixed...

So many people continue to have the AF problem that I find it hard to believe in the few that report good focusing. This has nothing to do with the 50L. The Sigma 50 has a serious flaw.

It seems that Canon is flopping bigtime with the new 18-200

The lens isn't even out yet... but it's flopping bigtime already?

I said it SEEMS, not that it HAVE allready flopped. Testshots on a
50D is out, there's an active thread about it now. If, and I say IF
the shots in that thread is what can be expected from that lens, it
SEEMS to me it will be a big fat flop.

85mm is a logical and good place to "attack" next. If they can give
95% of the performance of the C1.2 and f/1.4 at a price around the
C1.8, they might just clobber Canon again. One thing is for sure,
they'll hit where there is money to be made, and now that they have
the 30 and 50, 85 is the next big seller.

There is a difference tho between the 30mm (which is a crop lens intended to fill the void in 50mm equivalents on a crop camera) and the 50mm (which is a full frame lens).

I think the 30mm f/1.4 DC EX is arguably a much bigger "attack" on Canon who has not filled this slot in its line-up. As far as the 50mm Siggy, for all its glitzy big glass and glamour, the test results on full frame show it handily beat by the Canon EF 50mm f/1.4. Check the tests on a 1DsIII instead of the 450D. You'll see where the benefits lie.

Truth be told, that should be expected. The EF 50mm f/1.4 dates back to 1989, its remained in production essentially unchanged since then, because its a GREAT lens. A lens that was designed for film and works like a champ on film, and just happens to be pretty solid on digital also. Compare the same lens's results on Crop vs FF and you see how much a difference FF makes.

The Siggy 50mm is impressive that its "overall" sharpness at f/1.4 - f/1.8 seems better, but I've tried it on my 40D and it didn't have the pop I get from my Canon. Maybe I had a bad copy. I find that when I'm shooting @ f/1.4 - f/2.0 my DOF is so thin that my subject is the only thing in focus, thats why I'm shooting it wide open in the first place. In fact, I've had shots that I've deemed OOF because the DOF was so thin that half their face was tack sharp, while the other half was already melting into the background. Thats not a bad lens, thats a GREAT lens, but its one that most people don't respect cuz they didn't take the time to learn to use it effectively. If Sigma truly wants to rule this realm they need to add IS to these primes. I know, many people ask why add IS to such a fast lens? The answer is simple, try shooting @ f/1.4 - f/1.8 from candle light @ ISO 1600 even and get usable results... I dunno about you but for me hand-holding speed is about 1/80, not 1/15. I've missed some wonderful shots because of this. If they add IS, I'll buy it.

There IS a big open hole in the Canon 85's, and Sigma can easily do
what they did with the 50's. It's even easier, Canon doesn't even
make a 1,4, so there's no direct competition either.

I bought the lens a couple of days ago and after owning a Canon 50mm 1.4 and 1.2L I must say that I am very impressed by the Sigma.

The focus is a little noisier than Canon but it's as fast. The quality and focusing quality is much better than Canon's.

I don't care about the size or weight. I have a 1Ds Mark III which is heavy as hell and I am used to working with a 24-70 F2.8L 95% of the time so it doesn't bother me.

Like the DP Review says, it is probably the glass and the size of the lens that make it better.

Whatever it is, it is worth the $499... Only $100 more than Canon's crappy 50mm 1.4 and almost $900 less than the HUGE and SOFT 1.2L.

The build is excellent and since there is no zoom, you don't even have to touch the lens... As u know Sigma zooms in the opposite way, even on Canon EF mount which is confusing, not to mention Sigma's zoom lenses are hard and notchy to zoom...

So this is great so far. Great lens, great look, price and the performance is very impressing. I just wish the brand name was Canon... Maybe I should put a Canon sticker on it... For pride and the love of the Canon brand reasons only, u know...
Cheers

Jeff, the difference between 1.4 and 1.2 is almost none. I own both lenses and I got to tell u it's like the difference between 1/125 and 1/60. Not worth the extra $900.

And u didn't mention how hard it is to get sharpness on the super soft 1.2... Just millimeters off and the focus is gone...

Good to hear, I get more and more convinced that the focus issues reported by some people have been fixed.

I would not call Canon's 1.4 crappy, it's just old, and outdated now. The 1.2, now thats another thing, that's just plain cheating people IMHO.

What Sigmas are hard and notchy, all 4 of mine are nice, dampened and smoth, they give me a nice quality feeling when I operate them. Sure, they turn the opposite way of Canon zooms, but that's no problem getting used to.

If this lens was priced by Canon's marketing department, it would have to cost at least 50% more than the 50L. Proudly keep your Sigma stickers and lenscap, it shows that you buy quality, not just blindly follow brand names:-)

I was wrong about it being a 1-stop difference; it's actually a 1/2-stop difference. I just really can't imagine anyone thinking the Canon 50mm f1.2L is worth the money. And, I think it's an example of Canon wasting resources to make a lens that hardly anyone would want (with mediocre performance) rather than addressing the real deficiencies in their lens line-up.

This just isn't so. You are making the incorrect assumption that lens quality is all about resolution. This may be true to some photographers. As someone who likes to shoot people, I disagree.

The Sigma 50/1.4 has the the smoothest bokeh of the 1.4's, particularly wide open. It vignettes less than Canon's 50/1.4, and it's fun to use. It is intended for a different audience than Canon's 50/1.4, which is all good and well. For a landscapes stopped down, I'd recomment the Canon (with the lens hood to both protect the lens from stray light and the brittle moving front element and motor). For portraits wide open, go for Sigma:
