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.

Sigma changed the weight from 470g to TBA on their website. It seems pretty clear that the 470g was a mistake all along and that the lens will be considerably heaver than that (probably 600-700g).

the 35mm 1.4 is around 600g while the 85mm 1.4 is around 700g. so yeah, maybe 600-700g would be the expected weight.

If it was a comparable (in my mind) lens, it would weigh less either a 85 or 35mm, as it's closer to normal.


This lens is going to be a heavy mofo though, lots of lenses with big diameters.

if we are getting picky.... Audi R8 V10 GT, Ferrari F40, Porsche 959, Lamborgini Gallardo, Ariel Atom, Mazda 787... oh the list could go on and on. Too bad the last guy delivered my pizza showed up in a 1980's Dodge Omni with a missing tail lamp fixture

The car analogy actually goes well here, I prefer a lightweight/high output small capacity mid engine car with nimble handling to a muscle car

Back to the OP,should be a good lens, but the size and weight is a big ouch for me... I know a few people who shoot Canikon would go for this though, they have very positive experience with the 35 1.4 Art.

Was that the one with the anchovies or the extra dash of 30w oil?
