Sigma 85mm f/1.4 lens size specs


I fear I run the risk of sounding like all the iPad prognosticators I grow extremely tired of hearing, but I have a little more data on the upcoming 85mm f/1.4 lens from Sigma.

I was really interested in actual dimensions and weight on this lens for better comparison "on paper" with comparable lenses by Nikon and Canon in terms of handling. In response to a post I made on another forum, I was handed a link to lens specs that do include physical dimensions, but still nothing on weight. Here, we see the Sigma measures 84.7mm in diameter, and 87.6mm in length. Weight is listed as "TBD." One might guess that some materials are still not settled upon with finality, which could affect lens weight.

We can now see the Sigma is somewhat larger than the Nikon 85mm f/1.4 lens (80mm diameter and 72.5mm long) even considering Nikon's dimensions apparently do not include the lens mount flange. And Sigma comes in considerably smaller than Canon's f/1.2 hog, which measures 91.5mm diameter by 84mm long.

This Sigma lens, along with their previously introduced 50mm f/1.4 lens (shown at left), seem targeted to hit Nikon and Canon at points in their lens line where they are weak. Nikon recently introduced an upgraded 50mm f/1.4 lens, and canonrumors.com reports rumblings that Canon is about to follow suit with a 50mm f/1.4 update of their own. Would either company be likely to make a move on this type of lens without non-OEM competition?

How the Sigma lens will compare optically is a completely open question, since virtually nobody, save possibly for a few chosen souls covered by NDA, has shot with one yet. The added bulk of the Sigma compared to the Nikon lens may be explained by the HSM focusing motor, and will very likely be justified by better performance of the AF. The size reduction compared to the Canon offering will also with near certainty be accompanied by improved AF and MF performance at the paltry cost of 1/3 stop of light gathering power. (The f/1.2 max aperture serves Canon better in terms of bragging rights and profit margin than it does users in terms of usable lens aperture.).

While I enjoy and appreciate the faster apertures and (often) better optics of fixed lenses compared to their zoom counterparts, I don't own any right at this time and choose to rent them as needed, as Robert's Distributors in Indianapolis is a readily available source for me. I am normally reticent to go with non-OEM optics but Sigma has my attention with the 50mm f/1.4 and the 85mm f/1.4. It is impressive to me that Sigma is competing directly on lens build quality and performance and not just on price. Their 50mm is actually pricier than Canon's and about the same price as Nikon's. The Sigma 85mm will pleasantly surprise me if it comes in much below $1000.00 US, which would be lower than Canon's price and roughly the same as Nikon.. Whether or not I end up buying one or both of these lenses, I appreciate Sigma's mixing it up in the fixed-length marketplace.

Sigma 85mm f/1.4 update

I heard back today from Sigma on my information request about their upcoming 85mm f/1.4 lens. They told me that can't give more detailed information at this time on precise dimensions and weight of the lens, so I still can't do a direct comparison with the Nikon and Canon equivalents of this lens.

However, they did burst my bubble somewhat by stating this lens will NOT be compatible with a teleconverter. I was salivating a bit at the prospect of a single lens/converter combo that could obviate my need to periodically rent Canon's 85mm f/1.2 and 135mm f/2.0. If there were a matching 1.4X teleconverter, this lens could be both a very fast 85mm and a 119mm (which is close enough to 135mm).

Such is life. Hopefully Sigma will change their minds on this and issue a compatible converter, but I will continue to breathe normally in the interim.

Sigma 85mm f/1.4 HSM. Sweet.


Sigma, long a competitor in the pro-sumer zoom lens market, has also shown it is not afraid to mix it up in the higher-end lens market. For several years they have had well-reviewed versions of 70-200mm 2.8 and 24-70mm 2.8 lenses. They have also pushed into fixed-length (see this post on why I hate the term "prime" - except when it's used properly) lens markets with 300mm 2.8, 50mm 1.4 and others. Soon (thought no date was given), their newest entry in their "fast and fixed" line will be the 85mm f/1.4 EX DG HSM lens.sigma85_1.4.png

In Sigma parlance, "EX" refers to the special finish and higher build quality on its higher-end products, and DG refers to a lens suitable for full-frame digital and film cameras (as opposed to "DC" lenses, which are only for "crop-sensor" cameras, such as Nikon D300 or Canon EOS 7D, to name a few). HSM refers to focus driven by Hypersonic Motor.

I have multiple times rented the Canon 85mm f/1.2L USM (both the original and the "II" versions) lens for specific occasions when I wanted insanely thin depth of field or was working in ridiculously low light, such as a local college dance group that seems fond of performing in near total darkness. The Canon is a great lens optically, but it handles like a shot put. In addition to being larger and heavier than seems necessary, both manual and autofocus are slo-o-o-o-o-o-o-ow. The "II" version improved handling compared to the original, but only incrementally. Sigma's new lens is shown here in a photo provided by the company, apparently in Canon mount. Based on the known dimension of the mount flange, this lens appears to by noticeably smaller than Canon's big-ass 85mm, while only being a measly 1/3 stop slower. I would also say it is somewhat more compact than the Nikon 85mm f/1.4.

Way back in the day (late '80's), when I was a Nikon shooter, I owned a Nikkor 85mm f/1.4 for a couple of years. This was also a great lens optically, though I could never master getting basketball action shots reliably in focus with it at f/1.4. I may not do a whole lot better with that today, as that is very sparse depth of field. Nikon's current autofocus version of this lens appears to be the same basic design, though it uses the old-style body-driven "screwdriver" type AF rather than the newer, more reliable "hypersonic" style motor. Sigma's new lens will almost certainly be a faster, more accurate, and quieter alternative for Nikon users.

Do I sound like I'm looking forward to getting my hands on this lens for a test drive? Well, yes, I am. While Canon OEM zooms are my bread and butter, I do like a fast fixed-length lens at times for certain purposes, and am not married to Canon glass only. Sigma's 50mm f/1.4 lens is very attractive to me, though I've not sunk the bucks into one yet. It is well-reviewed around the 'net, but for my work, the 50mm is more of a "would be nice" than a "must have." That scale may slide once there is a sustained improvement in the economy.

With it's greater reach, the 85mm could rate as a "must have" for my work, particularly with the aforementioned dance/stage events, and also with high school/college diving and dog agility events, both of which involve fast action under dodgy indoor lighting and usually a ban on electronic flash.

Sigma's press release does not specify if the 85mm is compatible with a 1.4X teleconverter. The lens would almost definitely be a "must have" for me if it was 1.4X-ready, as that would essentially give me a dual-duty lens that would also replace a 135mm f/2.0 lens, which is another lens I rent on a recurring basis for similar events. I have an inquiry in with Sigma at this time. Not surprisingly, information on exact release date and price are not being disclosed at this time, though I was told June is a target for release. I also asked about precise weight and dimensions of the lens for direct comparison with current equivalent Nikon and Canon lenses and if the Sigma 85mm to get a better idea of the handling and flexibility of the Sigma. I am told answers on these questions may come by Monday.

I'll let you know.

She was truly a lady.


091114_Shania.jpgOur neighborhood is poorer as of yesterday with the passing of Shania, a lovely and charming Siberian Husky who shared her two bedroom, two bath, 1 1/2 garage home with my good friend (and best "man" at my wedding) Eileen Cantin.

Eileen writes in an email giving us the news: "Shania was an ambassador in the neighborhood, and a quiet greeter to anyone who came for a visit. She was a sweet companion who was much loved. She will be missed. Together she learned with Eileen after their buddy Silver died that life goes on in wonderful ways and good memories are a special gift."

Included with her message was this photo, which I took this past Saturday as we took a walk in the woods near Shania's home.

New iPod Shuffle - Apple gets a clue


At the much-awaited September 9 Apple announcement, newly-minted organ donation cheerleader Steve Jobs and Apple surprised pretty much nobody by revving up the iPod line. The Nano muscles up in ways that will surely keep it at the top of the music player heap, and the Shuffle gets a right-sizing and pricing correction.

While not the top of the line, the iPod Nano is the real flagship of the iPod fleet, and it was given a huge boost in value with the addition of an FM tuner, pedometer, and video camera with microphone not to mention the most appealing new feature, a $20.00 price drop on the 16GB model. The addition of a camera has been rumored several weeks since photos leaked from a Chinese aftermarket manufacturer of new Nano skins with a hole on the back that could be for pretty much nothing other than a camera lens.

With the broadest range of upgrades, the Nano was the star of the show. The iPod Touch would have been had it gotten its long-rumored camera. (The MacBreak Weekly guys seem to think this is a temporary design glitch and the photo-capable Touch will come soon.) But it may be that the first item from the event to cause me to open up my wallet will be the less-sexy iPod Shuffle. Here's why:

I posted back in March (here and here) when the new button-less shuffle first came out about my misgivings on the design. While I think it is undeniably slick, the proprietary headphones with inline controls and $79.00 price tag has held me back up to now. Though I've made peace with the headphones, it's hard to spend $79.00 on a 4GB shuffle when, for only 60 bucks more, you can get all the navigation interface mojo and video playing goodness of the 8GB Nano. But now, in addition to pretty new colors to choose from, I can now choose to get a 2GB Shuffle for $59.00. I think this is smart.

Really, how many people need 4GB in a shuffle? The shuffle is a playlist based music player. You don't really need a huge chunk of space for your whole music collection in this type of player. At four gigs, it's doubtful that battery would last long enough to continuously shuffle through all the music through even once. Two gigs makes a little more sense. I'd load a Shuffle two or three podcast playlists, and a couple or three music playlists, and one or two audio books. That's probably only a bit more than one gigabyte of media.

When you buy a shuffle, you just know you are handing Apple one of the largest, if not THE largest, profit margins for any hardware product they sell. But a $59.00 price tag makes this easier to swallow than $79.00.

Prognostication From A Dark & Smelly Place



I should probably start this entry by stating a few things that I am NOT. I am not an oracle or a psychic. I am not a Canon fanboy and am not in the Canon inner circle or connected with the company in any way. I am not a Canon evangelist or a Nikon detractor. (I have a spreadsheet calculating the cost/benefit of a switch to Nikon to prove that.)

Recently, a mole at Best Buy revealed new UPC product database entries had been created for the Canon G11, S90, and 7D. That a G11 was eventually coming is a no-brainer. The "G" series has updated on a more-than-annual basis for years.

The S90, on the other hand, is thought to be a much more counterintuitive development. I have to take other web posts at their word on this, since I do not follow developments surrounding this type of camera. But, if we accept that the S90 prediction was either based on fact or an exceptionally lucky guess, the 7D gets added credibility, as well as a blogospheric tornado of speculation on it's specifications.

To amalgamate the myriad estimations of 7D capabilities, the new camera will most probably:

• be anywhere from 12 to 21 megapixels.
• have one, or perhaps two, digic IV processors or debut a Digic V.
• do HD video up to 1080p.
• have a 3.9 framp-per-second shooting rate.
• or, maybe, 8 fps.
• or 5 fps. Who knows?
• slice.
• dice.
• chop.
• make julienne fries.
• cost about $2700.00 (body only).
• or around $1700.00.
• have built-in pop-up flash. Or not.
• employ an APS-C 1.6x crop sensor.
• Oh, never mind. It's full-frame.
• have 15 focus points.
• No, make that 19 focus points.
• why not one meeee-lee-uhn focus points?.
• give you oral pleasure.
• ISO 50 to ISO one meeee-lee-uhn.
• have weather sealing comparable to EOS 1D MkIII.

The preceding list, delivered with tongue causing a rug burn on the inside of my cheek, goes to show how useless any speculation, including my own, truly is. As the old saw goes, "Anybody who knows isn't talking, and anybody who's talking doesn't know."

But what the hay? Speculatin's fun.

I went on record with an email to my friend Ron Wise over a week ago with the following predictions for the 7D:

• 16-ish MP with one or two sRaw modes
• up to 1080p video
• motor at least 6.5 fps
• 1.3x crop
• "real" ISO ratings to 6400, with "cheats" up to 25K
• one CF and one SD card slot

As I read this a week later, I find I still agree with myself. Nothing there is a particularly earth-shattering or out-of-the-box prediction with the possible exception of the 1.3x crop. I haven't seen that prediction anywhere else on the web. And like every other prediction out there, I pulled that out of a very dark and smelly place. But it still sounds right to me. And here's why:

I think Canon has realized (or should realize) that the advanced amateurs at whom the 10D thru 50D series has been aimed are just about played out on 1.6x crop sensors. Nobody who has shot with or even looked through a 5D has not pined for a larger sensor. Another 1.6x sensor is not going to excite like an upgraded 1.3x sensor would.

Also, as I recall, the 10D debuted at about $2000.00, and the 50D is now listing for $1199.00. That's at least a 40% deflation in price in a relatively short few years, which has to cut deeply into profit margin. If, as some have suggested, a 60D is also about to be released, the expectation will be for a big boost in features at the same price, or an incremental improvement for at least a slightly lower price. Video capability of the Rebel T1i notwithstanding, the current 50D is a significantly more solid-built camera with many more features than the Rebel for not a lot more money. Canon surely wants to introduce a new pro-sumer toy that can command a larger profit margin. 1.3x crop on the sensor will help with this.

Releasing a 60D simply does not make sense to me. Releasing a 60D alongside a 7D would be market-diluting lunacy.

The sleeping giant through all this 7D rumoring is the surely-impending update in the 1D line. But lately I've been wondering if it is still going to be a "line" at all. Without a doubt, the Nikon D3 is the camera to beat right now. And Nikon has apparently abandoned any kind of crop sensor on it's pro cameras. Would this not put pressure on Canon to do the same?

I suspect we have seen the last EOS 1DS camera. The next pro camera will be full-frame and the APS-H sensor format will go by the wayside for pro Canons. That's another reason I think the 7D will be 1.3x crop. It will essentially fill the niche that will not be filled by a successor to the current 1.3x-crop 1D MarkIII (at least in my fevered imagination).

Were I CEO of Canon, engineers would have been tasked many months ago to design a camera with the fullest flexibility for any pro shooting situation. Need to shoot a full-bleed magazine cover or a portrait suitable for extensive retouching and uber-large reproduction? Shoot 25-30 megapixels with motor speed of around 5 fps. Shooting a fast paced sporting event where most of your work will display half-page or less in print or on the web? Drop down to about 12MP resolution and crank away at 10 or 12 fps.

Essentially, to regain it's competitive leg up, Canon should strive to deliver a camera that combines the Nikon D3 and D3X into one machine, and do it at around the price of the D3. In today's economy, few professionals have the luxury to specialize only in high-end commercial work at the expense of fast-paced editorial photography. And top-line cameras should not force professionals to pay top-dollar for a "specialist" SLR.
