Sigma reveals 18-200mm F3.5-6.3 II DC OS HSM with 'FLD' glass

By dpreview staff on Oct 7, 2011 at 00:06 GMT

Sigma has released version II of its 18-200mm F3.5-6.3 DC OS HSM superzoom lens. The latest version adds Sigma's FLD glass, the 'fluorite-like' glass co-developed with Hoya and features a revised design (it now features a narrower body and 18 elements in 14 groups, rather than the 13 groups of its predecessor). The lens will be available for Canon, Nikon, Sigma, Pentax and Sony systems (without optical stabilization on the last two mounts). MSRP will be $720.

Press Release:

SIGMA 18-200mm F3.5-6.3 II DC OS HSM

The Sigma Corporation is pleased to announce the release of the SIGMA 18-200mm F3.5-6.3 II DC OS HSM. This 11.1x high zoom ratio lens is designed exclusively for digital SLR cameras, incorporates Sigma’s original OS (Optical Stabilizer) function and offers a broad shooting range from wide angle to telephoto.

The SIGMA 18-200mm F3.5-6.3 II DC OS HSM is the successor to the SIGMA 18-200mm F3.5-6.3 DC OS/ HSM which was launched in June 2007. The lens is ideal for travel photography with a compact construction and length of just 87.7mm. This lens features FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, and SLD (Special Low Dispersion) glass elements providing excellent correction of color aberration. Aspherical lenses give excellent correction for all types of aberration and distortion. The Super Multi-Layer Coating reduces flare and ghosting, ensuring high quality images throughout the entire zoom range. Sigma’s OS (Optical Stabilizer) system offers effective correction of approximately 4 stops, enabling easy handheld photography. HSM (Hyper Sonic Motor) ensures quiet, high-speed auto focus and the inner focus system eliminates front lens rotation, making the lens particularly suitable for using the supplied petal-type lens hood and circular polarizing filters. The rounded 7 blade diaphragm creates an attractive blur to the out of focus areas of images.

* Sony and Pentax mounts do not incorporate Optical Stabilization

SIGMA 18-200mm F3.5-6.3 II DC OS HSM specifications

Lens Construction: • 18 Elements in 14 Groups
Angle of View (for SD1): • 76.5-8.1 degrees
Number of blades: • 7 Blades (Rounded Diaphragm)
Minimum Aperture (Wide): • F22
Minimum Focusing Distance: • 45cm/17.7in.
Maximum Magnification: • 1:3.8
Dimensions: • Diameter 75.3mm×Length 87.7mm / 3.0in.× 3.5in.
Weigh: • 490g (17.3oz.)

* FLD glass is the highest level low dispersion glass available with extremely high light transmission. The optical glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion. These characteristics give excellent correction for residual chromatic aberration (secondary spectrum) which cannot be corrected by ordinary optical glass and ensures high definition and high contrast images.
* Vignetting will occur if the lens is used with image sensor larger than APS-C size or 35mm SLR, and APS Film SLR cameras.
* For Pentax mount, auto focus will not be available on Pentax ist* series and K100D.
* The appearance and specification are subject to change without notice.

I'm trying since October 20, 2011 and it is fantastic.
Before I had the Sigma 17-70 2.8-4 and was a good obbiettvo, now with this new sigma can have more fun.
Before judging the red ring or the aperture 6.3 lift your butt and go try it.
€ 510.00 but for what you want? What do you expect?
Always convenient to make comparisons with optical prestigious, you should make comparisons with similar optical and price points, instead of doing the smart 80-200 f2.8 or f4 that belong to other levels.
This second version deserves the red ring, by virtue of the fact that the treatment of the lenses at low dispersion is identical to that of the canon, and repeat the same.
6.3 The diaphragm does turn up their noses at the most, but if you learn to shoot like I'm doing, instead of wasting time in chat would be better.
Some "teachers" in front of me after the usual stories described above, began to eloggiare mirroles and the new compact.
A wee bit of common sense farebe not bad.

It's 1/3 stop darker than the Canon/Nikon superzooms at 200mm, it has a price tag about as high as the Canon 18-200, it's a third-party lens so the af might be weird (my experience...), and the FLD lens in the already terribly unsharp lens design (if not redesigned) might make it as sharp as the Nikon/Canon superzooms. That doesn't sound attractive to me... The only reason I can find for anyone to buy this over Nikon/Canon superzooms is to trick people into believing they're using an L-lens

By gzsoldog (Oct 14, 2011)

It is an awful great MISTAKE to think to a tele lens like just an extension of the possibilities of your legs. Tele range in most cases are serving very different function, not just bringing closer the target:
- portrait is usually done in tele ranges not bec you can not go closer but because of different perspective and lower depth of field (much nicer differentiation of the target from the background).
- you can take pictures with very different feeling by tele then with wide, it is IMPOSSIBLE to make it by your 35mm (normal range) lens. A crowded street from one end is a typical example but of course there are several similar cases.
- And of course your legs can be great equipment but several times you need also wings to go closer, e.g. to flying birds, to scenery from the top of a tower/peek, etc. Accept my congratulation if you have also those facility.
About this long zoom lens: 6.3 at 200mm is a real pity but let us wait for the tests and/or samples, maybe we will see miracle.

I had the Sigma 17-70 HSM OS for Pentax before and the FLD performed well to control aberrations. I'm glad they took out the OS for Pentax and Sony mounts because it drains battery even when its switched off (floating lens elements are still gyrating to stay in-place). Sigma usually makes lenses for full format sensors, so its nice to see them focus on APS-C size to cut down the weight. I hope it performs well in practice though. Just like Pentax k-5, market prices will adjust the outrageous MSRP accordingly.

On a side note, that focus ring in stupidly tiny and recessed compared to the zoom ring. Fail.

Why the f/6.3 at the long end again - it's outside the working range for each and every AF sensor of cameras on which this lens could be mounted. So no matter what they did optically, they got their priorities seriously screwed up!

RKGoth
By RKGoth (Oct 7, 2011)

It's a spec difference, not a "won't work" thing. AF sensors are measured in whole stops.

I can assure you on every camera I have used with a variety of zooms (not just Sigma) ending up at a stated F6.3 - including the original 18-200 OS, on an SD10 and SD14, I've had no problem with AF.

0 upvotes
Karl Gnter Wnsch
By Karl Gnter Wnsch (Oct 7, 2011)

No, AF sensors are *not* measured in whole stops, f/5.6 is a physical limit that the AF sensors are designed to meet - to get a balance of precision and lens construction. AF sensors designed to work at f/5.6 are already less precise than ones designed to work at f/4, so allowing f/5.6 is a concession with regard to lens construction and price - at f/6.3 though part of the light path is partially blocked or affected by diffraction, DOF (depth of focus) is larger and thus precision is even further reduced. So to sum it up: At f/6.3 AF performance is seriously compromised if it happens to work at all! On Canon cameras such chimera lenses must lie to the camera about their specification because these would switch off the unreliable focus system alltogether if f/6.3 is detected!

Dewight McMullen
By Dewight McMullen (Oct 7, 2011)

Karl, you're overlooking the fact that AF systems always uses the largest aperture when focusing. When at the long end, the aperture will open to F3.5 and remain there until the shot is taken, at which point the aperture will close to F6.3. Sigma knows how to make a lens that will work with all the current AF sensors.

master381
By master381 (Oct 7, 2011)

the lens is physically f/6.3 maximum aperture at 200mm; it cannot open to f/3.5 at that focal length.

but to the original poster; i have a f/6.3 lens (tamron 18-270) and it focuses fine most of the time anyway at the long end.

4 upvotes
Karl Gnter Wnsch
By Karl Gnter Wnsch (Oct 7, 2011)

@Dewight McMullen: Yes, the lens always uses the largest aperture available but that largest aperture happens to be f/6.3 towards the long end and there is is in unchartered territory and will fail due to the constraints - and Sigma is guilty of ignoring the design limits of all current APS-C cameras once again, as I explained it will run into diminished contrast and signal fidelity due to diffraction effects on the light path, partial blockage and less precision - these effects can easily be seen by simply comparing such a lens focusing performance with a f/5.6 lens of similar focal length - the f/5.6 lens will focus more reliably with higher precision in more situations and with less contrast around the focus target...

By Karl Gnter Wnsch (Oct 8, 2011)

@vodanh1982: No, AF always operates at the widest aperture possible for the lens (and focal length if it's a variable aperture zoom lens). The lens is only stopped down to the selected aperture after focusing. That's why you have to give aperture control to the inept automatic on the Sony SLT cameras if you want to use AF in video or high speed series.

@Karl

"No, AF sensors are *not* measured in whole stops, f/5.6 is a physical limit that the AF sensors are designed to meet"

Karl, F5.6 is not a limit. It's a specification, and when someone designs an AF sensor that works at F8 or F11, they will say so.

Karl Gnter Wnsch
By Karl Gnter Wnsch (Oct 8, 2011)

@RKGoth, wrong, f/5.6 is the limit that *all* current AF sensors of APS-C cameras have built into them with regard to full functionality. Break that limit with the lens and the penalties are incurred. There are only a few cameras (and none of them is an APS-C camera) that have a single line type sensor to work up to f/8 - the physics for phase detetion make designing such a sensor increasingly hard and still it will be less precise on a faster lens than a f/5.6 limited sensor would - so f/5.6 is the limit that applies to fully functional AF sensors, I have outlined what happens if the lens doesn't adhere to this limit: You lose both precision and reliability - those are hard physical limits!
It's like a fever, if your body is operating at 39°C instead of the normal 37°C your mental and physical performance is seriously compromised, at 42°C your life is in danger - f/6.3 is similar for the AF sensor to you having a slight fever, your capabilities are compromised!

Tamron's version is generally poor, both the old and the new Piezo version, at tele end. Watch the digitalrev tv review and comparison of both. Nikon's own (which I owned 3 or 4 copies of) is decent until appx. 135, and then between 135-200 it is much to be desired. I can buy a used Nikon 18-135 lens for $175. What interesting in this version of Sigma i sthat they put their new type of glass in, which they also put in Sigma 17-50 F/2.8 and everyone seems to like the new Sigma 17-50 F/2.8. So I have high hopes for this 18-200 by Sigma with their new glass. I like the small size and lighter weight because those are used with DX cameras which are generally smaller and lighter.

I use nikon 18-200 F3.5-5.6 VR, and previously owned the first sigma 18-200 (no OS), and also the 28-300 btw, and well, sigma lenses are way cheaper, but shooting with them gives you photos that look... cheaper. At least it was on those first models.

If you want the best 18-200 out there, it is the nikon one, but tamron 18-270 is almost a better choice, as it is F6.3 at 270, but at 200mm may be you get f5.6, and quality, as far as i know, is similar in all the other aspects.

For me, color rendition on nikon one is far better than the sigmas i've tried, the rest may be is *almost* identical (except for F6.3), and may be tamron is in par with nikon too, I can tell about colors in tamron.
