Sigma 30mm in New Lensmounts
Sigma has just announced that its 30mm ƒ/1.4 EX lens will soon be available in Pentax and (heh, heh, heh) Konica-Minolta mounts. The latter meaning that sooner or later I will get around to testing it. The picture above is from dcview.com.tw, by way of GZLive.com, which has more pictures of the lens (which appears to be huge) mounted on a Nikon D70 at the link.

Just to point out that the article is at "dcview.com.tw" (no 's'), not at the "dcviews.com" site.
Your link works fine, but already having dcviews.com open in another tab I wondered why I hadn't seen the story myself! ;-)
Oh, now you've changed the dcview.co.tw link to gzlive.com, but still refer to dcviews.com (and link the picture to there?)
I think I'll go and lie down...
I've had a brief play with this lens on a D70 and it is indeed rather fat and heavy. I suspect on my Pentax DS it'll be a little overpowering.
Briefly looking at some old numbers, it's over 1cm longer and 2cm fatter than most 50mm f/1.4 lenses of yore (except for the canon ef one, which has a fat layer of...protective plastic armor). I think i'm going to go lie down too.
Yes. I had one briefly, and it is indeed big and heavy. So much for smaller formats giving us compact lenses and cameras.
I had to return mine because it was a dud. The center was actually less sharp than the edges!
I chose not to get a replacement, because trying it I realized I was not really hankering for a Normal lens. It is not wide enough to take in a whole scene, and not long enough to pick out details.
What we need are good, compact wide angle lenses.
What does it mean "heh, heh, heh" near Konica-Minolta?
Padys,
That's what I shoot with, a K-M 7D. So the lens being available in K-M mount means I get to buy another lens....
Heh, heh, heh. (g)

I suspect the size has a lot to do with the film-legacy flange-to-film distances. The smaller mirrors of APS-C cameras don't require it, but the lensmount standards do. Thus a 30/1.4 is basically just as large as a lens of similar specification would be for a 35mm camera, since the objective diameter would theoretically be the same.
I'm generally puzzled and disappointed by the size of reduced-sensor size lenses, though.
mj, have you tried the KM 28/2 lens? It is smaller than the sigma, full frame, sharper in the corners, and available now at B&H for an incredibly low price!
I wonder how long it will be called the Konica-Minolta mount? Soon I guess it will be the Sony mount or perhaps the Sony/Konica-Minolta mount or the SKM mount for short.
The sigma 30mm + antishake would be a heck of a low-light lens for obejcts that aren't moving very fast. I love mine and regularly use it for candlelight and dimmer situations anyway. Many, many samples here: http://www.flickr.com/photos/carpeicthus/tags/sigma30mmf14dc/
It's larger than a normal because … well … it's not a normal. It just plays one on TV. It's a wide angle lens that was designed to be made normal be sensor crop. It's a little fat on a D70, probably would be silly-looking on a Pentax, but has great balance on the D200.
Interesting to compare the Sig 30 with the Pentax 31/1.8 Ltd:
Width:
S: 7.5cm, P: 6.6cm
Length:
S: 5.9cm, P: 6.8cm (includes the built-in hood I presume)
Weight:
S: 430g, P: 345g
By all accounts the Pentax is a much better lens, just a shame it costs twice as much and is 2/3 stop slower, plus you need a Pentax camera to put it on ;-) Personally I'm saving the pennies for the DA21mm.
Is any heap (!!!) but not bad lens ~50mm (for ASP-C) that you could recommend for K-M 5D.
When will this lens be for sale in KM mount? I have not seen it anywhere since it was announced. Maybe it's not even going to come out in KM/Pentax mounts?
