DA35 2.4 vs Sigma Art 30 1.4 ?

Any experience with these two options?
I plan to use it for video as well.
I haven't used these lenses at all. In a way, i guess they will both perform well.
But maybe one has a specific advantage over the other?

I would be considering the DA 35 ltd macro + sigma 30 1.4, but that would have to be a 2 step purchase with a year in between...

thks!

Apples and Oranges?

Hello grispie,
I only have the DA 35mm f/2.4, not the Sigma, so bear that in mind.
While I'm very pleased with the overall sharpness, resolution, color rendition and AF speed of the DA 35, it must be understood that this is a consumer-grade lens. It is made to a specific price/user point and some sacrifices are necessary. The plastic bayonet mount, lack of quick shift, no (supplied) lens hood, somewhat lightweight construction (although, to be fair, I've found it to be sturdy enough for normal use), AF drive motor and likely some compromises in the actual materials used for the optics. For $200 USD, it is a very good value, but it's not high-end glass.
According to many reports, the Sigma Art series is made to very exacting specs, is all (or, mostly) metal construction, very well-corrected optically, features quick-shift, metal bayonet, HSM focusing motor, is 1-1/2 stops faster than the DA and would definitely qualify as high-end. The price reflects this, currently $900 USD.
The DA 35mm Macro would be a much closer comparison in quality, both in optics, quality and construction.
Again, the DA 35mm f/2.4AL is a fine lens, just browse the 'Plastic Fantastic!' thread. But, like most things in life, you get what you pay for!
JMO,
Ron

I'm confused. You said ART. So are you referring to Sigma ART 35mm 1.4 or the Sigma DC 30mm 1.4 or the Sigma ART 30mm which is not available for Pentax mount?

I was referring to the Art 30mm 1.4 for which i am sad to hear it would not be available in Pentax mount. Will it be futurewise?
The 35mm Art is very expensive but still attractive, yes...

As of now, I dont think it will be available in Pentax mount. Unless Sigma makes a surprise announcement or some sort.

then, except for the quite expensive and big 35mm Art, are there other alternatives?

The Sigma 28mm f1.8 macro might be worth considering. It is big...

The original Sigma 30/1.4 EX/DC is available used. For rendering, I'd say the Pentax is better if you want across the frame sharpness. For center sharpness only, or shallow DOF, the Sigma is better (eg portraits)

From everything I see about it I would go for the Sigma 18-35 f/1.8 over either of them. Supposedly it's like having a bag of primes on sharpness and it's pretty fast too.

the thing is that i have a DA15 and a DA70.
I'd be ok with a 30mm fast prime. the old sigma 30mm might do the trick. the sigma 18-35 is very attractive but relatively expensive and bulky. Seems a good lens for video though.

There's always the Pentax FA 31 Limited. It costs more than the others listed, though the Sigma 18-35 is in its ballpark. It's truly great.

If the Sigma Art 30/1.4 would be available in Pentax mount, I'd probaby get it to replace my 35/2.4. The Art 35/1.4 is better but much bigger and heavier and the old 30/1.4 isn't as good optically (from what I've read). The Pentax FA 31/1.8 is expensive. The FA 35/2 is another option, but not that much better than the 35/2.4 (only a bit faster with more PF at those apertures).

I had both the Pentax DA 35mm and the a Sigma 30mm EX DC f1.4. I sold the Pentax and kept the Sigma. While the Pentax is technically more consistently sharp across the frame, the Sigma is outstanding in the center and much faster. For what I do (weddings, fashion, portraits), sharpness in the far corners is not terribly important, especially considering I usually shoot at wide apertures so the corners would be blurred anyways.

It depends on what you need out of your lens. For example, I wouldn't recommend the Sigma for astrophotography because of the weak corners and pronounced coma around the margins of the frame.

Young Drake there has a point. I had the 35mm F2.4 and sold it. I have the 30mm EX DC F1.4 and use it, partly because I have decided I much prefer the wider focal length. F1.4 is, well, quite fast, and there are times I like to have the speed (normally when I am photographing moving things in poor light. The Sigma does have rather strange rendering at the extree edge of the frame, but the centre is sharp. It is not a large or heavy lens, but is well built. I have nothing against "plastic fantastic" lenses btw, I have the new DA50 f1.8 and prefer it to my F50mm 1.7 (although the M version is the nicest!)

i agree, with the crop factor, i'd rather have a 30mm or below...
