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.
