Sigma usb dock

Does anyone know if the new Sigma usb dock, that fixes AF issues and AF speed at home, will be compatible with the following lenses;

*Sigma 30mm 1.4 ex hsm
*Sigma 50mm 1.4 ex hsm
*Sigma 85mm 1.4 ex hsm

if so, then I will have no problems buying these prime lenses.

I'm pretty sure it is only compatible with their newer lines of lenses. Which is a shame.

But they are releasing a new version of the 30mm 1.4 soon, which should be optically better than the current one, so I'd recommend you get that one anyway.

It is compatible with the new 30mm f1.4 but not with the old one. Also not compatible with the current 50 and 85.

The dock will only be compatible with sigmas new line of lenses (Art, Sport, contemporary), it will not work with any of their older lenses.

Any idea how much the dock will cost? If too much, this new feature will be much less attractive.

no pricing released... some Sigma comments have hinted at 'not cheap' which could mean anything really...
my own rumors has this in the $500 range

Wow, $500, really? That would be terrible on their part. The rumors were initially saying around $200, which already seemed a bit high.

without knowing how the USB hub works, I would think that lens rental places would plan on stocking it...

I'm really wondering how they could get the price of such a tool up all that high. For everything I've seen it described as doing it does not sound like an excessively hard or complex device to produce, and marketing wise it would be far easier to recoup development and support costs by tacking onto the lenses it supports, not the device itself.

I have had my eye on the new 120-300 f/2.8 and a dock to go along with it, but if the Dock alone is more than $100-150, then I will have second guesses about it. $500 for a USB dock? At that price I will wait a few months for another geek to reverse engineer the dock, post details on its workings, and the build my own version.

And mine will be BETTER, with a racing stripe or something.

This shouldn't really cost more than 150$, hopefully less - it's probably a single chip solution with a couple of connectors, more like a USB dongle.

But you see, even though it is a very simple device, a lot of people are going need it, and when people really need something, they pay whatever it takes.

It is known, and this is why Canon can charge 700 bucks for an external Wi-fi tranciever.. How advanced is a wi-fi transceiver? It is something that even my old dumbphone from 2006 has.

I am not saying that Sigma is Canon, but they might have the same idea.

And they would be really shooting themselves in the foot then. Such a device markets beautifully as a low cost addon that greatly enhances the whole value of their new product lines far more than its cost to the end user.

By pricing low it easily becomes a feature of every lens to every user. Pricing high will negate it as a feature to many users.

The 30mm 1.4 has been discontinued. The new version will be out this spring (or fall where you are) In any case, that lens was being sold extensively in the states at $200 USD off the normal price. As a result there are very few left for a Canon mount. I of course don't know what the situation is locally where you are, but the new version (without the EX) may be a much better lens to start with. It's big brother, the Sigma 35mm f1.4 for FF bodies has garnered some great reviews so far.

Its a lot, but if they can encourage someone to invest in 3 of 4 of the new Sigma lenses, then the cost of a single dock might be considered much more cost effective. And if it can fix focus issues without a trip to Sigma, it might prove to be worth it for some.

I thought most of the rumours had it pegged at around $200? And if you know Sigma, you know they're not at all like Canon in terms of price gouging

Delays were announced by Sigma Japan on 3/27/2013.

The text below is from a Google translation from the Japanese to be found at http://translate.googl​e.com …ic.php%3Fid%3D5​06&act=url. It isn't perfectly clear if this applies to the new lens (120-300mm), the lens dock, or a bundled package. My guess is it applles to either the lens or the dock.
