Sigma 30mm 1.4

[Jon Foster]

I know this lens is not on the shelves yet but has anyone been able to touch one yet? I love my Canon 50mm 1.4 and in general like Canon lenses but I must admit I'm pretty stoked about the new Sigma 30mm 1.4. I'm thinking this would be an excellent lens for low light indoor shooting. My 50mm does a fine job but something just a touch wider would be perfect.

Anyone?

Jon.

Im curious to see results...but I havent even seen a review on it yet, a few stores say in stick soon and have it listed at $450 but other than that...its all I know. My 50mm was my fav on my film body, so the focal distance this would give me on my digital seems ideal...my only serious demand is solid AF since I end up shooting sports a lot...there is a lot of hype on sigma's new linup, let us hope they live up to the talk

Any reviews yet, one UK retailer seems to have stock, but no-one has reviewed it.
I neeeed one if it's usable at 1.4 or 1.8.

............I neeeed one if it's usable at 1.4 or 1.8.

I'm hoping for the best but expecting the worst............too.

I'm hooked already :lol:

The price is ridiculous. Canon's 50/1.4 which is second only to contax sells at 300...

In the UK the price is almost identical to the Canon 50mm 1.4, because we pay much more for Canon gear than the USA, the 3rd party gear is usually comparatively much cheaper.

[jyrgen]

The same in Estonia, both are list priced almost identical. Identically high that is, at $550 :(

I'm most probably getting one next week, at a super duper preorder discount price of $500 (EUR 400), which is comparable to buying from a decent German online shop plus shipping to me.

Not really ridiculous... what does the Canon 35mm f/1.4 or the Canon 24mm f/1.4 cost? It's quite a bargain when compared to those two...

[PaulB]

But doesn't it only cover APS-C size sensors?

[Tom W]

It only covers the APS-C sensor. It is HSM which is very good, and is considered comparable to Canon's ring-type USM. I would expect it to perform at least as well as Canon's 35/2, and probably better at wide apertures (obviously better at wider than f/2).

It's cheaper than the 35/1.4 for a couple of reasons - one, it doesn't have to deal with full frame, and two, its not a wide angle lens in the format for which it is designed. It takes a bit more optic chicanery to build a wide-angle lens than a normal lens, especially if you want excellent performance WRT color, contrast, distortion, and corner sharpness.

Like Paul B said, it can't be used full frame, which effectively makes it a knockoff of some 50/1.4 design.

$380 on sale...anyone seen results/tests yet???

[Bob_A]

It would be great if an MTF were available. Has Sigma published one?

The Canon 35mm f1.4L sells for $1120. However the Sigma gets you even closer to something matching a 50mm f1.4 on a film body for much less money. Here's hoping that the contrast and resolution can come close to the L.

As I mentioned before, don't compare EFS and full frame lenses. If you want to, you can compare 35 L to 22/1.4 EFS (nonexistent)

Or 30/1.4 EFS to 48/1.4 EF

The smaller the sensor, the easier it is to build the optics.

[DocFrankenstein]

And sigma's contrast and resolution absollutely HAVE to be better than canon's L, because of the physics.

If it's not, then sigma's technology put in this lens sucks.

[22littlereasons]

I'm salivating. This would be an awesome lens for indoor sports if it had a good review. All the usual places I check have them out of stock.

[blinking8s]

ive checked the camera store almost every day...let me see some dang tests! lol...

I don't disagree with you. It's just that would have to get an $1120 L lens to get the same job done with a 1.6 crop sensor. I don't particularly like the idea of purchasing an EF-S lens since I still use a film camera and like to have lenses that can be used on both. However, this is one case where it would probably make sense to me. As you mentioned, it is easier to build a quality lens at a particular focal length for smaller sensors ... so hopefully the Sigma will have close to the resolution/contrast of the 35mm L when used on a 1.6 crop camera.

... eagerly waits.
I will give up my sigma 20mm if this lens is sharper at f/1.4 or f/1.8

Whilst the maths work here, I'm not a statistician I'm a photographer. I have a camera with a 1.6x sensor, I would like a lens around 30mm (28 -35 would have to do) to give me the 'traditional' standard focal length. I would like it to be fast, and sharp wide open. It would be of great benefit if it had fast and accurate AF.

If the Sigma will give me this (If is still a question, as there's no test data yet), then why should I not buy it? On the grounds that it won't work as a semi wide lens on my non existant film body?

If money was no object, I'd have already bought the 35L, so would lots and lots of other people. However, whilst the 35L is priced in line with other fast non standard prime lenses, it's very expensive for us non-pro's.

Whilst I appreciate that it'd probably be a better lens on my 20d, and would also be usable on a 1ds or film body, I have no need for a 35mm lens for a film or FF sensor body. 600GBP for what would only be bragging rights has got to be beyond the pale, or am I a complete idiot for not realising that I should only consider L glass, and should never even think about buying lenses designed with a reduced image circle? Despite the fact that neither of my cameras needs a full image circle?:rolleyes:

*taps foot*

can someone buy one already?!?!? hehe

Oh my God, someone talking common sense! :lol:
