Panasonic updates five Lumix G lenses with Dual IS support

Not sure if you're being deliberately obtuse or what, but pretty sure than most photographs aren't shot at shutter speeds of 1 second. Most of my shots are at easily handholdable speeds. Even with long lenses shooting sports, I'm typically shooting at shutter speeds high enough that IS isn't really an issue.

You're taking the edge case and attributing the needs of that special case to all photography.

Let me repeat, since you seem unable to comprehend: I never said IS was never useful. I said that in typical shooting situations it doesn't make all that much difference, and that ALL modern IS systems, whether OIS or IBIS are very effective.

Neither of those statements is inaccurate, or even debateable, except by those who have an [Oly] axe to grind.

"I'm curious how olympus is planning to make dual IS viable"

Right now, Olympus IBISed cams only have two choice for OIS lens, using IBIS or using OIS, not both.

Will the olympus dual IS work with panasonic lens's ois though?

I think so if Oly wants to as Oly body can (?) read Panasonic lens's data.

Again, EM5 and EM1's IBIS have the same performance, but EM5.MK2's IBIS is better than EM1/5 as seem from above.

BTW, I bought EM5.MK2 very recently after bought EM5 not too long ago b/c EM5.MK2 has better IBIS than EM5.

I would buy EM1, but the IBIS is as same as EM5.

Oh, one stop advantage is a LOT once in the low light, such as f1.4 lens and f2 lens is only one stop. So does f2.8 vs f4 lens, or double the ISO may make IQ unacceptable in high ISO.

@MikeFL

E-M1 IBIS effectiveness is 5 stops by Olympus rating. And E-M5 has 4 stops. The E-M10 has 3-3.5 stops. And newer E-M5 II has 5-stops but it is more accurate for macro work than E-M1 is when camera is extremely still handhold. E-M10 II has 4-4.5 stops effectiveness, slightly lower than E-M1 and E-M5 II.

E-M1 and M5 are 4 stop by CIPA

Both EM10s are step down modes from EM1/5s while E-M1 is still the flagship of OMD line.

I really like to buy EM1, but I need one more stop IS from my EM5 after I used EM5 for one trip, so I bought EM5.M2 instead.

You are right on the EM5s' grip, both are as bad as you can get while EM1 is very good.

CIPA values has no accuracy for those. E-M1 is 5 stops like E-M5 II, the E-M5 II just has improved gyros that make it more accurate for very small movements that benefits like I said, when the camera is so still that it is almost stationary and then older gyros in E-M1 can't detect the motion accurately so they can go crazy, while E-M5 II does detect correctly and doesn't go crazy. To keep E-M1 from shaking you need to shake the camera to keep it steady in same situation.

The E-M1 has lot improved IBIS from the E-M5 and not at all same as you say.

And I didn't say anything about grip. OM-D grips are better than most what Canon, Nikon, Samsung produce for the asymmetric design.

OK

If they updated old cameras, why would you buy a new one?

Or it may require a processor or sensor feature that the GX7 can't handle.

Or new software code

Like he said, "Where's the firmware for my GX7"? Unless they're perceived as high-end, Panny seems to drop old bodies like they were hot potatoes.

Think the IBIS in the GX8 is a development over that in the GX7 - it's not the same.

Are you all new to technology? Have you been living under a rock? You have to pay for a new body with those features. Panasonic even charged people for a fw uodate in the past, why do you think theyre going to give stuff away for free??
