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.
