Not sure either what Sigma is up to here. These guys are odd f-length, sort of slowish and largish. They would sort of make sense if they
- are extremely high performance, however that is not what we typically see under the Sickma brand
- we are going to see them also for the APS-C mirror less (e.g. Samsung, Sony) in the future. The f-length makes a lot more sense for APS-C.
Just.spekulation here.

Mmm, actually that would make sense! Focal length equivalent of ~30mm or ~50mm indeed looks reasonable on some NEX or Samsung. Also that would explain relatively large (for a mFT lens) size: taking the filter thread as 46mm, the 19mm 2.8 lens is 50x60mm – much bigger than Oly’s 17mm 2.8 (22x57mm). We’ll see tomorrow <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='
