I know a pro who is using the Canon 28-300.... saying that the quality is 'good enough' but if he's lacking a shot because he's just switching body/lens....
In the old film-slr days a saw a pro making wedding shots simply with a Canon 35-70-lens.

As for your question:
The Pentax FA* 2.8/80-200 is told to be such a lens.

Never had this giant but had the 1.4/85 and still ahve the 2.8/200 and I'm wondering myself....
Very funny......

When i was asking about a zoom lens that performs impeccably compare to a good prime lens i was thinking of something a lot more portable then this , a walkaround zoom lens.....

While this may be true as a generalization it is not in fact true in real life. High quality zooms with modest (1:2, 1:3) zoom ranges are quite capable of matching even high end primes.
I started to respond to Stephen but it grew into a post that seemed a bit long for the forum - and perhaps not really pertinent to this thread - so I tossed it up on my blog. If anyone is interested, the subject is primes vs zooms. Executive summary: I agree with Stephen.

@guillermovilas: Please do not submit more photo. Your photos are wondefull, and is bothering my wallet.
Till now, i'm still seeking one single reason NOT to buy this lens.
Could you help me find the reason, guillermovilas?

Thank you guillermovilas! I see you have posted a couple at f/1.7. How do you find it at f/1.4?

Soft edges?
But I say, who cares? This is a lens for low light situations and when seeking the shallow DOF and other weird stuff. Then you can stop down to f/8 when you need a picture that is sharp all over.

I am still waiting for mine. Now I got a preliminary shipping date but I don't believe anything until I have it in my hand...

The reason which stop me (temporarily) to purchase this lens is the difference price between gray and official one.
The gray product price for this lens is ~ USD 352 while official one is USD 407. For big difference price between them (USD 55), i definitely go with gray produt.
The only problem is there's no Pentax mount available for gray product.
If it was available, i would definitely have this lens 1 month ago.

BTW, someone has compared this lens (in Canon mount) with some difference lenses. And this lens always won.

Sigma 30 f1.4 EX DC HSM vs Canon 28 f1.8 USM
Sigma 30 f1.4 EX DC HSM vs Canon 35 f2
Sigma 30 f1.4 EX DC HSM vs Canon 35 f1.4 L USM
Sigma 30 f1.4 EX DC HSM vs Canon 50 f1.4 USM

Here's the test
http://www.pbase.com/lightrules/lenstests

So i could expect the same performance in Pentax mount from this lens.

kyrios

Well, here in EU the Sigma is about USD 500-550. I wouldn't hesitate getting it for USD 352....

I had seen lightrule's comparision between the EF35/1.4L and the Sigma 30/1.4 earlier but I didn't notice he also tested it against the little EF35/2. Thank you for the link. Now I can only wait for my 550 dollar toy to arrive. It's ahefty price but one can't expect anyone to have it in stock for that price...

regards,

The only thing is that in Pentax mount it isn`t HSM , so the autofocus is noisier, doesn`t bother me.

Some will say that it`s a bit big compared to other standard lenses but again this doesn`t bother me either.

I`m trying to use it as an allround lens and so far it`s worked fine.
Ok you just have to walk around a bit to frame your subject but thats cool.

I don`t quite understand what you mean with the gray version ?

Gray product: does not distributed by Pentax Indonesia. The retailer import it by themself from Japan. Of course they give us 1 year warranty. It's retailer's warranty. If the unit broken or flaw, wil be sent back to Japan. USD 352.

Official product: Distributed by Pentax Indonesia. 1 year warranty as well. USD 407.

The difference between them is the resale value. A used Gray lens's price will drop far when for sale.

Very interesting because in german fotomagazin the 1.4/30 didn't get a good test result.
The 1.8/28 Sigma and Canon were tested better there.
Quite amazing to see this - but it may be that the test wasn't made correctly or the quality variation with (this) Sigma lens(es) is that big....

In the test mentioned above they were saying that even the Tamron 2.8/17-50 performed better than those 1.8/28-lenses....

That`s the thing with reviews , some are good and some bad.
You just have to compare them and see what makes sense, i usually go see at PBase.com and look at the results , they don`t cheat , what you see is what the lens really is capable of.

Reading what owners have to say about there lens is also a better alternative.

I wanted to buy a Tamron 17-50mm f/2.8 but it doesn`t exist in Pentax mount , by what i read it`s a very impressive lens.

Another good lens is the Tamron 28-75mm f/2.8 but it`s not wide enough for my use.

In pbase, lightrules said his copy was had focusing issue before test.
After been calibrated by Sigma USA, the lens has no focusing issue anymore.

So it could be the lens which is being used for testing by Germany photozine, it also has focusing issue. It's just my thought, can be (totally) wrong.
