Three new Sigma lenses announced

[Cadenza]

Checkout today's dpreview.com; it reports on Sigma's
announcement of three new DG lenses. There's even
an 18-200 zoom sporting an L-series-like red ring!
(I guess Canon can't possibly have trademark rights
on red-colored rings in photographic equipment.)

Here (http://www.dpreview.com/news/0502/05021401sigma10dgs.asp) are more details.

too bad no wide lens.

[aam1234]

They introduced 2 WA lenses actually but they are DC not DG. They are 30 f1.4, and 10-20.

[Chris1le]

too bad no wide lens.

Check this out:

10-20 (http://www.dpreview.com/news/0502/05021403sigma10-20dc.asp)

It looks like they simply "digitized" their current lens line up except for the three new lenses

[mbze430]

Ah, the other link took me to only the Telephoto....DOH!

10-20 looks good. Plus it's not ONLY EF-S...so this should work with all EF mount. That would be AWESOME!.

[DocFrankenstein]

They are 30 f1.4
Can you give more info about this lens?

It's exactly what I'm looking for right now.

[aam1234]

30 f1.4 (http://www.dpreview.com/news/0502/05021404sigma30dc.asp)

[CyberDyneSystems]

You know,. most of those lenses are not new,. nor have they been re-designed,. they have merely added the marketing moniker of "DG" to the end of the name to generate more "digital" appeal to existing lenses.

That's the bad part,.

...the good news is that the rumors of Sigma "discontinuing" some of there best lenses made (300mm f/2.8 EX HSM, 500mm f/4.5EX HSM, etc...) is unfounded as the lenses will live on ,. they'll just now have an additional "DG" sticker added to the Gold stripe and "EX" stickers :mrgreen: (and maybe a higher price again :( )

[DocFrankenstein]

30 f1.4 (http://www.dpreview.com/news/0502/05021404sigma30dc.asp)
Money... price... dinero... cost???????

How much?

CDS: Is the 30mm new or old one?

The last of three DC (digital SLR only) lenses announced by Sigma today is the 30 mm F1.4 EX DC HSM, a lens which sounds extremely interesting on paper and will offer photographers an almost 'normal' 45 mm equiv. (on a 1.5x FOV crop digital SLR) with a super-fast F1.4 maximum aperture (great low-light focusing, lots of depth-of-field control). This lens also features Sigma's HSM (HyperSonic Motor) and will be available with Canon, Sigma and Nikon lens mounts.
Sigma Corporation is pleased to announce the launch of the new 30mm F1.4 EX DC HSM lens.

This large aperture 30mm F1.4 EX DC HSM lens is designed to match the APS-C size image sensors of digital SLR cameras. Two SLD glass elements are especially effective in the compensation of magnification chromatic aberration. Glass mold aspherical lens at rear group of lens reduces color aberration and provides high-quality image results.
Dammit! I'm hyperventilating. :D ;)

Dammit! I'm hyperventilating. :D ;)

Same question I had for this and the 10-22...I am in need of a really good wide angle...been eyeing the 17-40 L, but the 10-22 would be nicer...:D

[johnbs]

I think CDS is too cynical.

The press release says that Sigma has optimized the lenses for digital.

That suggests that the lens coatings may well have been improved. Previous re-releases of Sigma lenses seem to be at the same price as before, so there seems no good reason to be suspicous of this move.

[CyberDyneSystems]

30mm is new,. sorry,. the first link Aam posted went to an announcement of ten lneses,. all of which are really existing EX lenses recently re-badged EX "DG" it's really a different press release from the one that Cadenze is referrring too.

The 30mm f1.4 is Very new and very interesting. Sigma's first 1.4 lens ever I do believe?

No I'm not too cynical,. it's the absolute plain truth ;)

Read the press release and tell where it says Sigma has done anything to the lenses like change the coatings.

"Optimized for Digital" is just catch phrase that a number of manufactureres have used to rekindle interest in there product line. Sigma has been playing this game for some time,. recently deciding to add the "EX" moniker to lenses that were not introduced as EX in the first place with absolutely no changes to the actual product,. besides,. the "DG" was allready stamped on some of these same products as much as 8 months ago if you bought them in Japan or other parts of the far east. (even parts of Europe?)

We had threads on this forum months ago from people asking what the difference was betwen the 50-500mm EX and the 50-500mm EX "DG" becuasre they were reading foriegn websites with the "DG" products advertised.

[DocFrankenstein]

Now that I look at it, my 70-200 2.8 APO has a sticker on it :lol::lol::lol:

Compatible with DIGITAL cameras.

Is this 30/1.4 full fram lens or not?
What's sigma's nomenclature for EF-S lenses?

[CyberDyneSystems]

It's for "APS" sized cameras like the Canon 1.6X digitals,. and Nikon Digitals, etc..

Sigma's nomenclature is "DC" for these lenses. ;)

[CoolToolGuy]

Ah, the other link took me to only the Telephoto....DOH!

10-20 looks good. Plus it's not ONLY EF-S...so this should work with all EF mount. That would be AWESOME!.

The 3 lenses in this announcement may mount on all EOS bodies, but they are specifically for APS-sized sensors (1.6). This is good news for 10D, D30 and D60 owners, but they cannot be used on a 1D, 1Ds, or any film body.

Have Fun,

[Jesper]

Here is an overview of Sigma lenses from the Sigma website:
http://www.sigmaphoto.com/lenses/lenses_all.asp

But I don't see a 10-20, 30 f/1.4 etc. on there (yet)....

I wish there would be something like the Canon EF-S 17-85 IS that would also fit on my 10D.

[Olegis]

The official announcements can be found at Sigma Japan site (http://www.sigma-photo.co.jp/english/), but no further information about the new lenses is available there either.

This 30mm f/1.4 lens looks very interesting and the 10-20 one is even more so ...

[Leon van Batenburg]

too bad no wide lens.

10-20 seems pretty wide to me...;)

Sigma have used the red ring for quite a while now,allthough i've only seen it on black consumer grade lenses

There is a common generic branded 100-400 lens that is white with a red ring ;) ;)

[gcogger]

Well the Sigma 18-125 will fit - no IS, though...

Exactly! The 30mm, 10-20mm and 18-200mm are all "DC" not "DG." And the 18-200mm is not an "EX" lens either, so it should be fairly inexpensive.

But a 30mm f/1.4 EX HSM lens is intriguing, even in DC size. Be interesting to see how it performs with respect to light falloff at the corners...

So, will we soon see the 'EX DC HSM OICU812B4' series? :lol: :lol: :lol: :lol:

The release states that it is for Digital SLR's only, with APS-C size sensors. That's the equivalent of Canon's EF-S.

Not quite... unlike Canon's EF-S mount I beleive the Sigma "DC" lenses will also work on Canon's older APS-C sized sensor dSLRs... 10D, D60, D30...

[Hellashot]

No. It is a size for 1.6x factor cameras so it is not like the Sigma 12-24 that will work on a normal film camera. I don't understand why these companies are making new lenses with a smaller size that WON'T work on a full frame/film camera.

Economics; it's cheaper, they're simpler to make and the market for APS-C is much, much bigger.

True. But the point I was trying to make, but obviously didn't suceed at making is that you can't use it on a 1 series camera.

But you don't need to - a 10 mm on the DR/20D is about the same coverage as a 13 on the 1D or a 16 on the 1Ds, and Sigma already makes full-frame lenses that cover those focal lengths. Or are you just being greedy? :{)#

[Cadwell]

Which is a real pain... but us 1 series owners have to accept that fact that we are a minority market and the big bucks in terms of volume sales is going to be with the APS-C sized sensor cameras. All of the lens manufacturers will chase the profit. Where Sigma have been clever from a market share standpoint is opening the door to the older dSLRs which is still a large market.

[johnbs]

I am interested in the claim by CDS that the DG versions are just repackaging - if that is the case, I have 3 counter examples which you can check on the Sigma site at
http://www.sigmaphoto.com/lenses/lenses_all.asp

Namely,

50 Macro, 105 Macro and 17-35/2.8-4

In each case, Sigma introduced a DG version that has some difference with the prior model - either weight (50 Macro) or number of lens elements (105 Macro, 17-35). In each case, the DG page specifically mentions super multi coating to reduce flare and ghosting when used with digital cameras.

So, CDS, where are your examples of lenses that they relabelled without any changes?

John

[CyberDyneSystems]

You've got me there John,

I've been reading all the press releases and not found any mention of new "optimized coatings" etc...

Seems your research has turned them up...

Tamron has been doing the same thing, re-namimg existing lenses and adding the "DI" moniker,..

Quite frankly I may have jumped to conclusions,. but I did read all the press releases I could find and never could find any specific mention of re-engineering.

I'd be interested to read what the coating differences actually are.

[johnbs]

So would I!

Note that my research applies to other DG lenses, so there is no certainty that these ones will have optimised coatings, but I believe that is a reasonable assumption.

I guess we have to wait and see the details on the Sigma site :)

[RoB_m]

so what's the 10-20mm going to cost, cause i want it!

[ScottE]

Sigma have used the red ring for quite a while now,allthough i've only seen it on black consumer grade lenses

There is a common generic branded 100-400 lens that is white with a red ring ;) ;)

I believe Sigma use a gold ring on their EX grade lenses. Red rings are used on Sigma consumer grade and Canon L grade lenses.

White lenses are just a reflection of the colour of people's faces when they see the price tag.

Scott

[Olegis]

There is also a green stripe on a black lens body - on Canon DO lenses. :)

[mbze430]

Here is a little clip from Sigma's website

"**Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras."

So really, it should fit all Canon Body, it just optimized closer to the middle from vignetting. The question is...HOW BAD of the Vignetting??? ..... I still like to use the 10-22 on my film SLR!

[johnbs]

How bad on a film camera?

Bad enough that you will wish you bought the 12-24 instead, I believe!
