They said the same about new 30/1.4. But still no new Sigma 30/1.4 for Pentax.
It's standard answer. I think.
How long ago did they give that answer?

it could also be argued that with the glock if it was dropped in cold weather and the plastic was cracked/compromised there could be an issue with it. This is why my friend whos in a local gun club does not allow glocks. I'm not knowledgeable about firearms so I'm not sure the validity of the claim.
I'm no gun expert either, but based on this vid, the plastic glock is made of, take the cold no problem.

But no version for Pentax. Even in the future. Is there any sense of discussing this lens?
Sigma replied that eventually there would be a Pentax lens (how it was interpreted here).

I think the main reason Pentax isn't making a 50mm f1.2 is AF. At f1.2 the AF would be unreliable, not to mention DoF would be so thin that even a slight shift between the focus confirm and shutter action could cause things to go OoF. This would be bad news for Pentax, because a lot of users would once again blame the AF system (often pointed out as Pentax' weak point) or the lens being unsharp, rather than learn how to use the two. Well, this, and the fact that f1.2 is a niche lens and wouldn't sell as many units as a trusty DA 50mm f1.8.

And regarding some of the comments, of course there are lenses larger than this new Sigma. But how many of them are 50mm f1.4? (not counting medium format lenses ) But I do agree that Sigma has been getting very good over the past few years. In the past, it was often dismissed, but now it rivals "the big boys." And I guess it has to make an overengineered lens to compete against the "regular" 50mm lenses that camera brands are offering

I'm fine with plastic barrels and other external construction for weight savings, and modern polys are pretty decent. However, plastic internals does scare me as I would worry about premature wear or the general longevity of the lens. All that being said, I much prefer a full metal construction as I have dropped lenses in the past and I do prefer them not to crack or brake. I've only dropped my M200f4 in cold weather and had no concern, but I fear if I dropped my DA*50-135 what would happen.

Why does it need to be this big though? It appears to be similar in size to Nikons 85mm f1.4 G

Looks bigger to me! Dunno. I think they're trying to over-correct... but I'm guessing it will be a top-notch lens. We'll see.

Based on the pictures, Sigma seems to be taking the nickname Bigma to heart more generally....

PENTAX not interested in fast glasses (see the new DA35 and DA50), and those who produce fast glass not interest in K-mount.

o.0 ... not good.

The 18-35 is like taking forever to arrive for K-mount.

Same as Ricoh Imaging thinks in terms, financial years and budgets, Sigma, Tamron et al think in similar terms as well.

So if for the FY 2013 all of the parties — based on mutual communication — knew Ricoh Imaging is working on technologies that will be introduced only very late in that year (the K-3) to refresh its camera lineup and more products to come in the following year (2014), it is very probable that we shall see more commitment from Sigma and Tamron after the April 1st 2014 when such commitment was budgeted for.

Unlike users with unrealistic expectations, companies do tend to think in broader cycles and longer terms because they don't have endless resources and unlimited manufacturing capabilities.

I wonder if the aspherical element will create onion bokeh highlights like the current Sigma 50/1.4, or if they learned how constuct the element differently like Samyang with their 85/1.4 (smooth bokeh highlights).

I'm glad Sigma is brave enough to try these new lens designs, it's good to see more options on the market. Now if only they made a 58/1.4 sonnar.

That's a monster lens! According to Imaging Resource: Dimensions (L x D): 100 x 85 mm (3.9 x 3.4 in.), Weight: 470 g (1.04 lb) - and 77mm filter thread!!

That's more than 2x the weight and 4.6x the volume of the FA50/1.4! It's even 2.2x the volume of the DA55/1.4 (but it "only" weighs 95 grams more). And it's 3.5x the volume of the A50/1.2...

So... F/1,8 is slow glass, and F/1,4 is fast? It's just half a stop of difference.

If you take many assertion posted on forums as any measure of common sense, or even remote resemblance to any photographic knowledge, your circuits with evaporate in no time.

Boys will be boys and faster is always better just like a muscle car beats any other even if you just deliver a pizza...
