Hi guys, please give me some comment on the question...
thx a lot

shooooooooooooooooot.

IS is only to compensate your handshake while holding the camera upto 4 stops

however, is it crucial?

from this comparison, it looks like IS does a lot better than having a better IQ
a630 has 1/1.8 while a710IS has a 1/2.5

still wondering IS or not

IMHO, IS helps a lot.

Some may say, must be skill and have steady hands to get good shots.

However, I disagree because it's the photo that matters. As long if the outcome of the photo is good then we should be happy.

IS may possibly help save the best shot in your lifetime.

In my opinion, just get a cam with IS.

I own the S5Is. But I think better ISO quality much better then IS. Eg, Fuji F31fd

I would have preferred both. hehe
I would have to admit that higher ISO allows you to stop down further in a not-so-bright condition. But if you want to shoot macro or insect, or you intend to do a heavy crop, IS will be better because no matter how good the sensor is (even under ISO80 for S3IS), heavy crop under high ISO will be noisy.

IS isnt crucial for still pic but absolutely a must for taking video.

yes for taking pic IS helps alot but i can do without it.

Could any1 show what's the best pic so far taken with IS?

How great photographers of the past do without IS?

Without IS? Use tripod loh.

1/10 sec. Hand held. Couldn't have done it without IS.

1/10s no need IS la, sap sap water.

i can easily get a sharp pic with lumix tz1 OIS at 1 sec, the longest is 1.5sec handhold, 1.5sec is abit hard tho.


without IS fuji f20 the slowest SS is 1/4s handhold:


both pic 100% crop, check the exif.
fuji without IS i can easily get sharp pics by using the burst mode, hold the camera steadily take 3 pics in a row, at least 1 or 2 is sharp.

The best pic with IS is not better than the best pic without IS.
When shutter speed is fast enough, then the limiting factors are the lenses, imaging sensor, and other techniques.

But, without IS, it is very difficult get even acceptable (ie. free from handshake blur) pics at slow shutter speeds handheld.

So, IS doesn't make your best picts.. betterer.
But you get more good and acceptable pics. Something like lowering the passing grade of a test so that more students pass that exam...

But for the rest of us, IS is the 'crutch'.

D@mn... I'm old. 1/10 without IS? I can hardly do 1/30 without IS. LOL

disclaimer: thats is without zoom.


at full zoom (focal length:438mm) with my tz1 at x10 optical zoom, i just tried the slowest i can do is around 1/10s.

iso200, 1/10s, 438mm.

Try taking macro without IS and you'll know how difficult it is. As well as when in high zoom.

At any rate, GreyPJ has just shown he is an exceptional person when it comes to hand-holding steadiness. Even the 1/10s shot at 438mm focal length shot is unbelievably steady!!

But, again, unless you believe you are the exception, IS will seriously help you. More so after a long photography session holding heavy camera gear or if you are the type that likes to drink coffee. Don't even mention Parkinson's disease...

Urrgh.. After looking at GreyPJ's photo, I start to wonder if I have minor Parkinson disease. IS is very very important to me, especially when I'm taking pictures indoor.

no no guys, i think everyone can do it, my secret is using the burst mode, (hold the camera steadily, press the shuttur button down and take a series of pics consecutively) for that max zoom pic i took 5 pics in a row and there are 2 sharp pics, 3 blurry.

had i taken just 1 shot it would be 99.9% blurry, IS wont help.

woah credit to greyPJ for teaching us the technique
tq for all of ur comment

It is better using burst mode with IS, right?

No wonder lah. I drink 3 cups of Nescafe a day. One in the morning to kick start my day, one after reaching the office while having the morning meeting, and one after lunch when I feel sleepy.

This is a great tip. Never have thought of this before. Thanks greyPJ for the tips.

Oh.. I never tried using burst mode to get clear pics. I'll try it soon.

photo taking noobie here... wad is ISO? useful?

ISO=film speed=how fast the film catches light.

I was in a dilemma before IS or ISO. Fate has it if nobody wants to buy my f40fd by 23rd I'll stick to ISO then, ha.

There's also another factor: image quality at a given ISO setting.
Sure your camera can do ISO1600 or whatever, but are those pictures pleasant to look at?

ISO and IS complement each other. Better to have them both. In a perfect world, I'd go for higher ISO but with very low noise and no other side-effects of anti-noise algorithms (eg. softness) but until that day arrives, IS is already here to help you to better use those low to medium level ISO settings.

What about a film camera that have IS?

All this while whenever I heard IS = digital camera.

Is there such a thing?

For film cameras, the IS is in the lens...
Obviously you cannot move the film - not like today's CCD-shift anti-shake mechanisms.
To support their film customer base, and also to make good profit margins, Canon and Nikon keeps their IS or VR in the lenses for their D/SLRs.

thanks 4 ur explaining..means higher ISO, better image quality?

for me the higher ISO .. the worst image quality as the noise inside the picture will gonna kill you...
but sometimes you have no choice had to increase the ISO...
