Sigma APO 150-500mm F5-6.3 DG OS HSM

I just called the camera shop about this one.

They said that it runs about $1100 bucks for K mount.

I didnt ask about the HSM. Will my K10D (and soon, K20D) support sigma HSM?

this looks like the one I want, but it may be slightly slow at 6.3 on the long end.

I'll probably rock this lens at weddings during the ring exchange for the closeup on the hands and on the first kiss for a closeup on the faces.....

thanks

Hmmm I thought the real Bigma went for only about that? Heavier but gets better reviews.

well i just got off of the phone with the camera shop. they said that yes, without a doubt pentax will support HSM from sigma.

i always hear about the bigma...what is it? is that the 50-500?

ok it looks like the 50-500 is about 100grams lighter and about 40mm shorter

its f4 on the short end while the 150-500 is f5 on the short end

i am constantly wary of using lenses that have so much range. i feel that a lens designed for 450mm range of focal lenghth will have more limitations than a lens desiged for a 350mm focal length. am i right on that?

the other thing is that from 50-135mm ill be on the DA* where i can hang down below f4 if i want.

currently, my only other long lens is a cheap sigma 70-300.
all i want is a quality lens to reach out past my 50-135 that i can use for professional work.

the 50-500 will have the first 100mm on the short end going unused.

i guess my question would be this: is the image quality better on the 50-500 throughout the 135-500 range?
in addition, is the 150-500 lens one that will deliver professional image quality?

thats all i really care about.

Well, there are a few more things to think about.

If you already have an image stabilized Pentax body, then that OS won't be all that much useful to you. Everything I have read to date states that having two IS systems isn't productive. They tend to work against each other and cause worse results. You would be forced to turn one off, and buying a lens with it built in would seem to be a waste of money and added weight to little good purpose if you already have a body that has that feature. (I won’t go into which system is better, as that just opens a kettle of worms).

Likewise, don't discount that bottom 100mm. I have a Bigma in a Canon mount. Remember that this lens does have HSM (and yes, there is a noticeable difference in focusing speeds between an HSM and a non HSM lens), but no IS. The Bigma consistently got higher ratings over the older 150-500mm lens in IQ. If the price is the same, I would definately go with the Bigma EX lens.

Here are a few examples of some photos I took this past Saturday with a Canon 20D and my beloved Bigma.

Chako, I'm not sure what you're saying here. OS? Two IS systems? The Bigma or the 150-500 are not a stabilized lenses. HSM is the motor system to drive the AF.

Anyway MJB, were you serious about using a long lens like this for weddings? I've shot several and have more coming. The longest lens I use for this is the Sigma 70-200 f2.8 and there are times I wished it was faster. I rarely go past 135-150mm with it and that's only when I want to get some candid people/crowd shots. Most of the time the Tamron 28-75 is on one body and last year the other body/lens combo was an FA50 f1.4.

Now as for professional quality. The Bigma is a good lens but it's not an FA* 300 f4.5 or something similar. It's just not that sharp. Plus in indoor lighting it's going to have issues with AF. Particularly at the long end. Weddings happen faster than most realize for the photog. And the last thing you need is to be fighting with your camera during the first kiss. Now the lens is not bad for manual focus and has a clutch which allows easy AF/MF transitions.

If you really think you need glass that long for weddings (I really don't think so) then save up for a 300 f2.8 from Sigma. A slow zoom is just not going to cut it.

Btw. I tried the 150-500 and the 170-500 (both in stores) and the Bigma is the better lens IMO. It has better IQ and sharpness but isn't any faster.

You could also get a Sigma 70-200 f2.8 or the new Tamron version and add an AF1.7 TC to the combo for more length. I'm sure Frank can find you one.

OS is Sigma's euphemism for image stabilization.

Check here. I presumed this is the lens the OP is talking about?

As for weddings...stay clear. Too slow and too long for anything remotely useful at a wedding. You would be better off with a fast 70-200mm zoom, or a prime in the same range.

A few Bigma shots from me as well:







But you'll note that very few users will post indoor shots. I bought mine for wildlife/nature shots. I really wouldn't consider it for much else.

One more Oh yeah thing. There's a Bigma right now on the market place for $900. Very fair price for it and you can save some off the dealers price.

I'm REALLY looking forward to the 120-400mm and 150-500mm for Canon. If the 120-400mm performs well, no one will want to buy the much more expensive 100-400L.
If the 150-500mm is ~f/5.6 at 400mm, then it would be a much better deal than sticking with the 400mm.
Nice to see that Sigma is releasing these new lenses for Pentax WITH HSM!

Chako, OS is not available on the Pentax variant of this or any other Sigma lens. So that
s not going to be an issue. It's not on the Sony version as well for the same reason.

Oh I see. Hmmmm...then I hope it is cheaper then the OS variants for the other brands.

I do recall an article a few months ago where a magazine did a testing on the various forms of IS, and they were able to use an IS lens on an IS body (Olympus I think). It is not recommended.
