Yesterday we reported on Sigma’s 24-105mm lens appearing on their website, being announced and then disappearing. Today, the company is ready to come clean with the new art lens boasting a constant f4 aperture throughout the zoom range as well as optical stabilization. Meant for full frame cameras, the lens will come in Canon, Nikon, Sony Alpha and Sigma mounts.

As for the stuff you care about, the lens will boast a minimum focusing distance of 45cm–which is pretty darned close. Plus it will have 9 aperture blades for super creamy bokeh and 19 elements in 14 groups. When we think about this lens, we can’t help but wonder if Sigma is late to the game on this one as Nikon has a 24-120mm f4 zoom lens that is pretty darned solid. Though Sony doesn’t have a near equivalent and Canon’s version has massive calibration issues, it will be interesting to see how this lens will do on the market. We see it doing incredibly well if the price is right.

We can expect it in November of this year, and the company tells us that there’s a strong chance that we’ll be seeing one at Photo Plus. Tech specs are after the jump.

Sigma Announced a 24-105mm f4 DG HS OSM Lens, Then It Disappeared

Sigma-24-105mm-f4-DG-OS-HSM-Lens5-640x379

Upon waking up this morning, we read the news about Sigma’a 24-105mm f4 DG HS OSM being announced on both Imaging Resource and Photography Bay. The lens was quietly announced as seemingly no one knew about it nor were any rumors or hints ever dropped.

But at the time of writing and publishing this post, the lens can’t be found on Sigma’s website at all. The product page now brings you to a 404 error as if it didn’t even exist.

However, before it was launched we were able to find that it has 19 elements in 14 groups, 9 aperture blades, is an external zoom, and obviously has image stabilization in the form of Sigma’s OSM. We’ve got no word on how many stops it compensates for though.

For what it’s worth though, if the lens is real it will have some stiff competition in the Nikon realm but probably not that much in the Canon realm. The Canon equivalent was my bread and butter lens for years until it drove me nuts with calibrations problems.

Specs are after the jump. No word on price, but we can expect it in Sigma, Canon, Nikon and Sony Alpha mounts.
