Sigma 105mm OS Macro - Is Canon in the Target Market?

Since most tests test the performance in line with other lenses they don't pick up on the problems the lens had close to 1:1 magnification - there it is and probably will be for a long time the worst of the lot...

I really don't understand where you are getting all this negativity about this lens from. No lens owner or reviewer agrees with you at all.
That is because he had problem with one lens so he thinks ALL Sigma lenses are bad.
Basically it makes him a Sigma hater.

The only time a smaller sensor with the same pixel count is superior to a larger sensor (aka higher pixel density) is when you are focal-length limited.

No we don't have $1400 price. We have $1400 MSRP. S stands for Suggested. In Canon new interpretation S stands for Street. This lens is going to be priced at least $100 less than Canon 100mm F2.8 L. And after a while $200 less. Here is another way to figure out. 150mm was $779 now $1099.
Old 105mm was $479 plus $320 for OS so it would be $799.

Yes. I understand what MSRP means. (I'm being very patient here Eugene.) But the fact remains that is the only price Geenine has seen. The only thing we can say with confidence is that with an MSRP of $1400 (even Sigma dollars) it will be no bargain.

Nonsense. We've just been through all this with the 70-300L for example - now about 35% less than launch price, just as those of us with a bit of common sense knew all along and said over and over.

I'm sure it will be less than the Canon L - if they want to sell any. And let's not twist my words here, I didn't say it wasn't going to be less. I said it wasn't going to be "excellent value for money" compared to the Canon. But I don't mind trying to be a bit more specific. A quick comparison of the prices of established lenses - MSRPs from the Sigma US web site and street prices from B&H - suggests a fairly consistent 1/3 off. So $1400 -> $925 say. The Canon is $999. If you think $75 less is a bargain, then we've worked out where we disagree.
 
Noise as in noise or what was called grain in the film days? Like how there is more noise in a ISO 6400 pic compared to a ISO 200 pic? What does the lens have to do with noise? It doesnt.

Sure you can use a lower ISO setting with a larger aperture lens but not sure what you mean by even with a 2.8 lens there was noise in anything but good light. Your statement isnt making any sense to me. Noise will increase with higher ISO setting or if you under expose and push the exposure in post. But other wise more noise wont increase with a certain lens UNLESS you raise the ISO setting.

Noise is related to the camera body your useing not the lens itself. Keep the ISO on say a 7D at 100, shoot the scene with a sigma 105 and then a canon 100 macro and the noise level will be exactly the same.
I was talking about noise in anything but good lighting, that should not be the case with a f2.8 lens.

If you had read my posts rather than spreading prejudice you would have seen that at one time I evaluated two of their macro lenses - and found them to be lacking both in performance and build quality. Today - after losing 500 Euro in suddenly worthless (non functional and no resale value because of botched flash protocol implementation) Sigma equipment - I wouldn't take a Sigma lens if it were anywhere near OEM lens prices...

So if you have common sense why you keep repeating $1400 for Sigma if you know very well that it will be no where close to this price?

And how do you know that? Have you tested it yet? Have you seen tests yet.

Another thing. Remember 70-200mm OS price. It wasn't selling as good as Sigma predicted. So they lowered price from $1699 to $1399. So if 105mm is not selling they will lower price to make it "Excellent value for the money"

But I don't mind trying to be a bit more specific.

That would all depend on tests results.

The interesting thing about people on this forum is that they expecting lower prices from Sigma disregarding the fact that some of the lenses are on par with Canon, some are even better and some Canon does not even have.

So if 105mm OS is the same quality as 100mm L why shouldn't it be the same price?

Oh, I read all your posts. And I am absolutely right about you. The prejudice is on your hands not mine. I had problems with Sigma too, so what? That does not mean I am going to write the whole brand off. No one is perfect, not even Canon.

I mean noise as taking people shots out side in less then good lighting, as in lower ISO settings it has more noise then any other f2.8 I used.

So what I'm saying is I don't think it's really a true f2.8 lens, a slower lens has more noise in less the good lighting, like my old sigma bigma f6.3 DG 50-500mm.

It had more noise then my canon 400mm f5.6, and it also had much more trouble AFing, in less then good lighting as my canon L 400mm, my 400 still AFs even when the lighting will not give a good shot.

It also extends unlike the Canon.
the Canon has an IF design which means it has a shorter effective focal length for closer subject distance, unlike the Sigma. Whichmeans that your actual working distance and background blur is a bit lower than with the Sigma (not sure though, because there are several factors involved).

P.S. regarding 'lower optical quality': both the Canon 100USM and Sigma 105DG get a four star rating from photozone.
forget the stars look at the plots

they also gave the 24 1.4 II a poor star rating despite setting records for center sharpness and being corner to corner sharp on FF stopped down a bit just because it had blurry corners at f/1.4 for a wide angle! no wide angle has good corners at f/1.4 come on!

but again don't forget the extending barrel and lack of USM!
 
My two Sigmas are among my most used lenses, but there is such a thing as being completely blinded by loyalty and that is the only explanation I can suggest for your position on this.
What we may have here is one person (KGW) who would praise a coke bottle top at $3000 if it had a Canon brand and another (Greenie) who seems to be a Sigma fanboy. Never the twain shall meet there I'm afraid.
 
Nonsense. We've just been through all this with the 70-300L for example - now about 35% less than launch price, just as those of us with a bit of common sense knew all along and said over and over.
where where

i haven't seen much of a drop (I see $1519 and wasn't it $1599 at launch?), but if you know of a reputable place where it is 35% off intro price I might give it a look over

if you know of a place where it is like $1050 please reveal
 
The Tamron and Tokina both have a similar mechanism - but they needed only one switch (the one built in into the ring decoupling), the Sigma needs to be decoupled and switched to MF by separate switches.
yuck, i love switching back and forth between AF and MF for macro, some scenarios i do way better with AI Servo (yes even for bugs+macro distances!) and in others I find MF works better
 
Sigma makes some good glass but canon makes better glass, sigma is a 3rd party maker so everyone should under stand that, that is also why most of sigma's lenses are cheaper then canon's.

If I remember right a place that rents lenses out, stop having sigma because of all the problems they had with them, the fail rate was much higher they said, and I'm pretty sure canon holds it's value better as well.

That does not mean sigma's are junk I have a 105mm macro, and also had a bigma DG 50-500mm as well, but I knew what I was buying, and was ok with my choices at the time, I was one of the first buyers of the bigma DG.

In fact they had lowered the price on the older none DG bigma then, and I ordered one and they sent me a DG one before they was on the market even, the price was right and I was going to upgrade later, when I had more funds.

Disagree on both counts.

There are many examples from Sigma there their lenses are better than Canon and there are some lenses Canon does not even make.

The reason Sigma is cheaper because they "try" not to rip buyers off. Despite SD1.

Right, have you actually meet these guys in person? I had. I could tell you few things but I doubt you believe me.

The problem here (not for Sigma) is that Sigma completely changed their optical formula 2 years ago. I had very few Sigma lenses back then but now is a different story.
In fact they had lowered the price on the older none DG bigma then, and I ordered one and they sent me a DG one before they was on the market even, the price was right and I was going to upgrade later, when I had more funds.
Have you tried the new one OS yet? I suggest you do. You be selling DG version very fast. I did not buy it for OS. I bought it for sharpness through the whole range. And it is my hiking lens now even though it is not light.

I strongly resent the fanboy badge - If the Canon lens were a coke bottle bottom I would say so, I can apreciate third party lenses (I have some and I'll get another one in short term) just not Sigma until they relent and license the protocols, they got it wrong once too often and I lost quite a bit hard earned cash by trying to save a few Euro by buying Sigma...

I was referring to UK prices. Launch price was £1600 and people were actually paying that (or very close) in the first few weeks. I paid about £1050. The price has drifted slightly upwards following the Japanese situation but I imagine it might reach the magic £999 once the shelves are full again.

UK prices are quite a bit higher than US prices of course, not least because they include 20% VAT.
 
But I don't mind trying to be a bit more specific. A quick comparison of the prices of established lenses - MSRPs from the Sigma US web site and street prices from B&H - suggests a fairly consistent 1/3 off. So $1400 -> $925 say. The Canon is $999. If you think $75 less is a bargain, then we've worked out where we disagree.
That would all depend on tests results.

The interesting thing about people on this forum is that they expecting lower prices from Sigma disregarding the fact that some of the lenses are on par with Canon, some are even better and some Canon does not even have.

So if 105mm OS is the same quality as 100mm L why shouldn't it be the same price?
Once again please don't make out that I said something I didn't. This all started because I pointed out that a £20 saving for a known lower spec lens - the Sigma 105 vs the Canon non-L - was not exactly the bargain of a lifetime.

And yes, we know very little about the new lens but it doesn't have hybrid IS (or Sigma would be shouting it from the rooftops) and it doesn't have internal focusing, both factors which reduce its value compared with the Canon. So given a realistic estimate of $75 saving - that's no bargain either.

As for the general comment about expecting lower prices from Sigma, yes I do and historically they always have been better value for money. That was a major reason why I bought my 18-50/2.8. But if the choice was between two identical spec lenses, one from Sigma and one from Canon, for the same price, I would buy the Canon. Wouldn't you?

But it is NOT KNOWN-LOWER-SPEC lens. And it is not £20 savings either.

Again, Sigma is not shouting because the are very modest and they let users to determine how good their product is. And just because Canon has Hybrid IS does not actually mean it is working the way they proclaimed it should work.

The is also possibility here of Nikon patent infringement so maybe that is why they are not shouting.

Nope, that would depends on whose lens is better. Even if Canon was a little better for a little more money I would buy Canon. I am not brand loyal. Until Jan of 2010 I mostly had Canon lenses. Actually I only had one Sigma 12-24mm and 150mm macro. Over the years I had few Sigmas but IQ did not impress me too much.
And the one with good IQ I had to sell because it caused me tennis elbow.
Yet I just bought it again. It is 120-300mm OS.
But now I like some of the Sigmas better.

I still have many Canon lenses that Sigma most likely will not replace though the one on the right 70-200mm F2.8 IS L is on Ebay right now. And few week ago I sold 100-400mm because I like 50-500mm OS better. No more white lenses for me.
