Third party "IS" lenses" - Whats the story?

oktx · 5th of December 2006 (Tue)

Canan does not have "IS" built into the body of the 30D. They take the lens approach which as I understand it is the superior technology.

So whats the status here? Who makes them and in what configurations? What are the prices like? Are they any good? Is there a tradeoff? Are we going to be limited to buying only Canon lenses if we want "IS"?

Sigma makes "OS" (optical stabilization) lenses, but from what I understand, the technology doesn't have all the kinks worked out quite yet. ...As in it works, but not as well as Canon's. I'm not sure of any of the other third-party manufacturers.

Non-Canon IS lenses are pretty limited but out there. What length zoom/prime are you looking for?

pieq314 · 5th of December 2006 (Tue)

Sigma has one OS lens: 80-400mm OS. It certainly costs a lot less than Canon's IS lenses in similar zoom ranges.

I remember seeing one post from an owner of this lens that stated that it is similar to Canon's IS.

If you are an owner of this lens, how many stops do you gain after turning on OS?

Sigma has another OS coming out soon: 18-200mm OS.

By the way, the Sigma 80-400mm OS seems to be a hot lens: a lot of places are out of stock!

I'm not actively shopping right now. I'm just about ready to order the 30D (my first SLR) and was wondering what the market situation was right now and likely to be in the future. Eventually I'll want additional lenses with IS. I just want to have the widest range of competitive products from which to choose. IS seems rather pricey right now. Worth it though, I'm sure.

if you are going to get an IS lens... I personally would stick to Canon lenses for now. SIgma seems to be starting to release new lenses with OS reports are shakey (har har har).

$$$ but yeah worth it in a lot of cases. I can't say I'm too thrilled with IS on short lenses, but it helps out GREATLY with longer lenses... and could help out greatly on macro lenses.

i really do not see the point in the IS lenses at all....#1 - set your shutter speed high enough to avoid blur (but what about low light situations) - #2 - then use a flash! (but what about trying to get that natural lighting look! #3 - its called "flash compensation"...turn it down to -2, and bounce your flash up or to the side...you will get natural looking photos without the blur everytime.

yes i know, as of right now, my signature says IS lens in it...but i am saving up for L glass, so trust me, can't wait to get rid of it.

LOL, there is an ON switch for the IS you know

Sigma makes 2 OS lenses, the 18-200 OS and the 80-400 OS and I have both and they are very good lenses. For those relying on the fact they read that they are not, I have read that Nikon is better than Canon many times, so maybe I am a fool but am quite happy with my lenses & Canon bodies they fit.

I have often thought the same, however only time i can see it useful is when your not allowed flash! i.e. a gig or something.

But even then you will probably need f2 and that restricts you to not many, if any Canon lens!

Good info, the post was from 2006 before the second SIGMA OS had been marketed.

MAny of us have waited for years for SIGMA to fully embrace this tech, the 80-400mm OS was 2004.. and yet only one more lens since then.
They have som super obvious choices for adding OS, the Bigma OS would sell like freaking Iced Cream in the Kalahari,. the 120-300mm would be a great choice, and the SIGMONSTER 300-800mm and there fine 500mm f/4.5 prime,. Please SIGMA?

cicopo · 16th of October 2007 (Tue)

CyberDyne, I sure like the way you think. If my 50-500 had OS it would be permanently mounted to a crop body.

If the venue is dark enough that the shutter speed is below what I can handhold and I set FEC to -2 the shot will be about....drumroll....two stops underexposed. If flash is my primary lighsource and I tell the flash to expose about 2 stops under then why would the camera come up with proper exposure?

IS on a wide to normal lens is actually at its best coupled with bounce flash. The difference is that you do not have to set the shutter speed so high that the flash is trying to do 90% of the illumination.

Since you have a 17-55 IS try what I do for shooting people indoors (sitting around chatting, not playing volleyball). Set the aperture/shuutter/ISO so that the ambient is about 2 stops underexposed. Set FEC to about -1/3 stop and bounce. Don't worry if the shutter gets down to around 1/40, the flash will freeze the subjects.

If you try that with a non-IS lens you will notice the background (which is almost completely exposed by ambient light) will become unsharp or even blurry do to camera shake.

It's simple. Drag the shutter a little bit, let IS save the background and rely on the flash to freeze the subjects. Ignore people who insist that IS is of no use on anything but a telephoto.
