E-P1... why IBIS is invaluable to me.

A true statement, but would you have had your D700 with you? With tripods the saying is the best one is the one you have with you, and I think it also applies to cameras.

Oh, for sure. That is why im interested in the GF1+20 1.7 ... or possible a 50mm 1.4G and Canon S90 combo. Im not entirely convinced that EP1/GF1 are carry every type cameras.. the EP1 i tried at the Henrys did not fit in my pocket; although, the pancakes make them portable... not true pocket cameras like the S90.. but, im waiting for results of the S90 since i dont think Canon made any real breakthroughs.
 
I would say that your post title should be "why IS is invaluable to me"...

You are saying "sometimes you use a fast pancake lens with no IS and you have to stop it down so IBIS is invaluable". Invaluable? Thats stretching it a bit. It's more like: "Sometimes IBIS can be useful, the same way sometimes fast focusing can be useful or built in flash can be useful". I could show you situations where having a flash could make the difference between taking a photo or not taking a photo.

Sorry but your post sounds very biased...
 
Unless you're trying to be an 'objective' reviewer, you're bound to be biased by your personal needs and preferences... seems quite natural to me.

That's why I said it was invaluable to me ... in my experience, IBIS is invaluable in situations where I require stabilisation with lenses that don't have OIS - which is the vast majority.

If you only use stabilised lenses, or never photograph in these situations, this won't be relevant to you...

In another example, I find the OIS on my PanaLeica 14-150mm invaluable when I want a stabillised superzoom lens on the smallest dslr possible - the E-420.

Kind Regards

Brian

The advantage of IBIS is that it works with all lenses, not just the three mFT lenses with OIS plus a couple of OIS FT SLR lenses (probably discontinued). In particular the new 20/1.7 MFT lenses does not have OIS, and that is the natural comparison to the 17/2.8 used in the OP. The extra speed of the 20/1.7 would have been useless, as DOF required f/4.5 anyway.

If one wants to expand lens options by using FT SLR lenses or non FT lenses, the vast majority of them do not have OIS.
 
GH1 = best sensor and fast autofocus
GF1 = small size and fast autofocus
E-P1 = small size and in-body IS

Out of the current crop, I'm leaning towards GH1, but it's not an easy decision!

Might fit in a belt pouch that is genuinely wearable --- unlike the top loader I have for my DSLR (and that is a small DSLR). My reading glasses don't fit in my pockets either (except maybe in winter).

Unfortunately, only on a subset of Panasonic kit lenses.

I enjoy having stabilisation for all lenses with the E-P1 - the flexibility is invaluable to me.

Although I am a big fan of Nikon's in lens VR (70-200mm f2.8 VR), I have started to appreciate the merit of in-body IS since I bought the E-P1. It is always there regardless of lenses. This is especially useful when I shoot with my old OM lenses

I don't want to get into the whole debate about IBIS and in lens IS, or whether Olympus' approach is better than Panasonic's approach. However, I do wish Panasonic and Olympus could sort out a more integrated approach.

Well, human freedom, and the notion of each respective's competitive advantage may lead them to make choices about their own direction...if each cannot obtain a critical mass of customers, then market forces may force a change....
SteB said:
My own feelings are that IBIS should be on most cameras and lens IS used for applications like video, where maybe OIS has an advantage.

Seems, to me, you have identified precisely why they have gone in different directions.
SteB said:
I think it is not too late for an integrated approach to be adopted and it would be best done in the early days of m4/3, rather than in a few years time when it is realised how many problems this dual approach to IS creates.

One can have compatible systems, with distinctively different approaches. Panny is more of a video company, and Oly a photo company. They each want to work off their own strengths.

Hello everyone,

following the discussion in this thread :
http://forums.dpreview.com/forums/read.asp?forum=1041&message=32893700

I thought I'd illustrate why having In Body Image Stabilisation (IBIS) can be so useful for my photography. Yesterday I found myself with a few minutes spare to pop into our city cathedral - I wanted to take a shot of this statue - which was in a fairly dark corner of the cathedral, and from chest height.

I wanted a reasonable depth of field, and the lowest possible ISO for good IQ... so selected ISO 200 and f4.5 - this resulted in a 1/2 second exposure handheld .

E-P1 + 17mm f2.8
1/2s f/4.5 at 17.0mm iso200
[ photo ]

So, sometimes you won't be able to rely on a large aperture to capture a low light shot you want, and the pleasure of having the E-P1 with you is not having to be weighed down with a tripod - also, you won't always have something to lean on (to get the necessary angle, this was taken with the E-P1 up above chest height and forward)

I wonder, given those parameters above - and that you seem to have a steady hand, if you couldn't have pulled off the same thing with either the 14-45 OIS or 14-140 OIS.....

The maximum aperture at 17mm on the 14-45 is F/3.5 and on the 14-140 it's at F/4.0 so you could have gotten the DOF you wanted, I suspect the OIS units would have done as good as the IBIS system in the E-P1.....

I'm just wondering why you couldn't have pulled that off with one of the OIS wide angle lenses.

Possibly because with a pancake attached it fits in his pocket. More likely because he is just playing around with the discipline of just have a single prime lens.
 
I have to say, I'd have quite a difficult time giving up the in body IS, but that's just me. It would be very difficult to decide between the GF1 and the E-P1 if they were both sitting here. I've been having a lot of fun attaching "cheap" non IS lenses to the E-P1 and it would be hard to give that up, especially if the high ISO was not quite as good on the GF1. For example this shot (I resized it ) was taken at about 100 feet with a 500mm lens (1000mm equiv) that I bought on ebay for about $20. The exposure was 1/125 at ISO 1600 and the lens was set for f/11 as I recall (it is an f/8 lens, but sharper at f/11). This is handheld while I sort of hid in some brush ha. Manual focus of course.

 
For some reason images viewed here always look softer than the originals, must be some kind of re sampling going on.
 
Looks like the default is a larger size than I uploaded, the expanded view is enlarged from the 1024 wide shot that I used.

Hi Brian! I'm working like crazy but like the job, so no complaints here :).

Fair enough, and I didn't know that, but still my point remains. Something with the AF speed and multi-aspect sensor of the GH1 and the in-body IS of the E-P1 would have me reaching for the wallet. Barring that, I am trying to be patient (or at least satisfied with DSLR purchases :-p).

Btw, I finally tried the E-P1 and can't see any reason whatsoever to complain about the LCD. Damn good LCD, in fact.

Indeed: I ofetn photograph in museums, churches and such where tripods are forbidden and often flash too, and I want lots of DOF in a wide angle composition. Then IS is very desirable, as not even larger sensors will not help. (Why? The DOF requirement forces using higher f-stops with a larger format, and so a higher ISO, canceling any noise advantage at equal ISO speed.)

Smaller kit, better in low light, higher resolution: choose any TWO.
