Now that don’t happen often, does it? Unless you live in Egypt or Australia (or …), ibises don’t fly that often into hotel rooms. So imagine my surprise when a 5 stop IBIS landed right in the palm of my hand in the very center of Paris?
Gone potty? Not really, as I’ve always had screws loose. But the ibis in question is the internal stabilization system inside my lill’Olympus OM-D E-M5 camera and it is pure magic (as befits the name, since Thoth is the Egyptian God of Magic and is often represented Ibis-headed).
Nuff with the silliness 😉 The little thingy inside the OM-D is neither legend or mythology. But it is pure technological goodness that works little miracles of its own and, when the sky turns deep blue and the clouds all purple, and your hand-held pictures still look sharp, you can be excused for feeling awe and magic in the air.
It works along 5 axes, which is better than four, better than three and probably better than two, as well.
In the good old days of 2-axes IS, you had your back covered if you suffered from that exotic plane-tremor, a.k.a 2D-jiggy. Then came 3-axes IS, which by some sprinkling of fairy powder induced evolution allowed you to tremble the human way. Now, wait for it, we have 5 axes, which mean you can shiver on a boat pitching in a tourmented sea like a rapper on steroids and still bring back sharp memories for the family ! A May Zing.
Enough boring techno babble 😉
Thing is, Thoth inside (R) or not, my first tests left me with a rather luke-warm impression of the system. Using the 45mm 1/8 Olympus (gem of a) lens, I managed 3-4 stop gains with IBIS on compared to IBIS off but found that the OM-D + 45mm combo required higher speed than an equivalent focal length on the Sony NEX-5n, for instance. So the actual gain was more like 1.5 – 2 stops.
Worse still, my recent Street of Paris by night with the OM-D post, in spite of showing the first ever real photo of a ghost (2 in fact), attracted vehement criticism because my IBIS-demonstrating shots with the 45 were no slower than 1/100th of a second.
So I decided to conduct a little test before the impartial jury of the setting sun, using the ISO-27003-standard sharpness test target : ugly brick walls. No one can accuse me of acting like a photographer inserting street photography images in a blog post dedicated to street photography. Not this time. Ugly & boring is my motto of the day. Pixel peepers can wet their pants over this one.
For this test :
What you are seeing in this post, then, is a series of shots taken in the decreasing light of a sunset and the challenge was to determine how far into the night and long-exposure territory I could maintain it.
The first picture is the test scene in good light. It is close to as sharp as the camera + lens (Panasonic Lumix 14mm f/2.5) will produce hand-held. I recommend reading the picture captions for tech info and an uninterrupted sequence.
Even later. This time I upped the ISO to 500. F/5.0, 1/4th. Perfectly sharp and in focus. Great image quality all around.
A 100% view of the previous image. It’s past 10PM and almost completely dark, as you can tell from the window lights. Impressive quality.
All along the post are successive exposures as night fell. 3 hours in the lab I remained, foodless, companyless and boozeless in the name of photographic science. I hope this clears my Karma of all debt and that all artistic sins are forgiven. Pfew !
As I found previously, without IBIS I am unable to take consistently sharp pictures below a speed of 1/f. In this test, the 1/13th exposure is blurred.
After this set, I repeated my experiment with the 45. I shot series of 3 images at several speeds with and without IBIS. At 1/50s 2 out of 3 were good. At 1/30s, none were really tack sharp. This is better than my previous results, but not as good as I previously experienced with my NEX-5n (routinely using 1/15th with the 25mm Biogon). With IBIS on and adjusted to 50mm lenses, I got sharp pictures at 1/5s and could probably have gone on. Here’s a full size sample. It’s slightly blurred because of the heay diffraction at f/13, but it is rock stable. That’s over 3 stops better than without IBIS.
As I estimated before, IBIS brings at least 3-4 stops of stability, which is enormous! Given my greater difficulties with stability using the OM-D compared to the NEX-5n (stiffer shutter release ? Clunkier shutter ? Unsupportive grip ? …) I’d guess the advantage over the NEX-5n is around 2 stops. Meaning ISO3200 on the NEX-5n should be compared to ISO800 on the OM-D.
Pushing it too far. ISO1000, f/2.5,0,6s. Noise is high but only present in luminance. Almost stable but not quite. Focus not quite perfect either. This is pushing too far. Although the picture doesn’t show it, it’s totally dark.
Leaving aside technical considerations, what I love about these pictures is the subtlety and fullness of colours. I have altered the slightly wavering white balance in some pictures but saturation and individual colours are untouched. Compared to many other cameras, the OM-D E-M5 really is a prodigious colorist in the noblest sense. No over saturated exaggeration, but a real balanced and subtlety that cannot fail to please. With other cameras in the past, I could come home and look at my pictures on the laptop and wonder why I had made them in the first place. This doesn’t happen with Lill’Ollie. See “Looking Down” (a couple of pics below), for instance. Make that picture grey and off-balance, and it looses all its meaning. It’s simply wonderful here.
A bothersome aspect of high-ISO performance and internal stabilisation is that they always seem to serve get-the-picture-at-all-costs purposes. It’s alright if you don’t get that shot. In fact it’s better than getting a noisy and slightly blurred one that will stay for ever on a hard drive or on a Facebook page for all to revile.
What I’m getting at is that technology doesn’t replace careful shooting. For all its marvel, IBIS doesn’t replace a tripod. Here’s the same scene with the camera (perilously) placed on the window frame and exposed 30 seconds at f/4.5 and ISO200. The full aperture high-ISO IBIS-enabled version does not come even close to this one. What do you think ?
Just for fun, here are more stabilized images with long exposures. For some, I used available hand, elbow or shoulder support, but still, results are impressive.

Awesome commentary and umm.. test.
Love the output from this camera. Why won’t it arrive already!
Ha ha. Love the “umm..test”. Guess I’ll never be a good reviewer, but hopefully will entertain a few readers 😉 Thanks for the kind comment. I wish you all the best for when your copy arrives. You’ll love it.
Cheers,
Pascal
Bonjour Pascal,
Bravo pour votre site ainsi que vos tests. J’arrive après la bataille mais j’aimerais si possible revenir sur votre expertise du nex7. J’aimerais en effet acquérir ce boitier mais je m’interroge comme beaucoup sur les objectifs à utiliser. Les zeiss sont trop cher pour moi. Les Sel Sony sont critiqués sévèrement aussi. Dommage pour l’automation en vidéo par ex…
Alors, quid des sigma 30/1.4? que me suggérez-vous?
L’OMD est attractif également mais le boitier me semble trop encombrant.
Merci en tt cas pour votre éclairage.
Bonjour Dominique,
merci pour vos louanges 😉 Je n’ai jamais pu tester le Sigma mais beaucoup de sites en disent du bien. Je ne connais pas bien les Sony mais il faut relativiser leur ‘mauvaise’ performance. C’est vrai que les petits pixels du NEX-7 sont exigeants en termes de qualité optique mais à f/8 bien peu d’objectifs sont réellement mauvais. Et si on n’agrandit pas vraiment beaucoup, ces différences restent souvent très secondaires. Si les Zeiss sont trop chers, il ne faut pas hésiter à se tourner vers Voigtlander (cf lapetiteboutiquephoto.com) dont la gamme est moins chère et vraiment excellente. Ce sont des objectifs qui ont une personnalité. Ils sont moins parfaits dans un labo que les Leica, mais les images produits ont beaucoup de caractère. Mais ce sont tous des objectifs manuel alors que les Sony bénéficient de l’autofocus. Vous pouvez aussi acheter un NEX-5n dont la résolution est 20% moindre que le NEX-7 mais qui est beaucoup plus tolérant et moins cher. L’ergonomie est moins agréable, mais avec le viseut externe on doit se rapprocher du NEX-7.
L’OM-D n’est pas gros du tout. Par rapport à un NEX-5n, il est plus haut, mais c’est tout. C’est un appareil complètement différent du NEX-7. Il ne fonctionne réellemnt bien qu’avec des optiques m4/3 mais il est autofocus, stabilisé et extrêment accomodant. Alors que le NEX-7 demande un peu de rigueur. Il aime bien les trépieds et les mises au point soignées 😉
Je n’ai jamais effectué de tirage de grande taille avec l’un ou l’autre (je ne possède pas de NEX-7, à mon grand regret) mais plusieurs blogueurs experts ont visiblement tiré en 50×75 à partir de bonnes photos de l’OM-D. Ce qui est déjà plutôt bien …
Voilà , j’espère que ça vous aide un peu. C’est toujours très subjectif et si vous avez la possibilité de les essayer, même quelques minutes, ça vous donnera très rapidement une indication sur la sensation que vous procure l’un et l’autre et l’envie de faire des photos avec. A ce jeu, l’OM-D est vraiment dur à battre!
Bon choix 🙂
Pascal
I wish Sony offered a very high quality “pancake” lens for their NEX like Oly/Pana do for their micro4/3rd’s. But, a lens is a lens is a lens and all that matters is the nutter behind the LCD/eyepiece, right? 🙂
The OM-D is interesting in the way it tries to go “retro”. I’m old enough to remember the introduction of the film OM-1. Boy, that sure set the world on it’s ears. It caused quite the scandal when National Geographic tossed their Nikons for the Olympus OM.
A friend just picked up a Panasonic GX1 and a few lenses. He loves it so far. He bought the silly thing even though I urged him to look more carefully at the NEX. Such is the lack of my ability to influence. LOL!
Hi Christopher,
thank you for your kind comments and my apologies for the very late reply. As you can see, I’ve been off air for a long time and hope to find more time soon 😉
I’m old enough to remember the OM too and how much I wanted one without being able to afford them. The E-M5 is my revenge 35+ year later 😉 And it does seem a worthy successor. Now, if they made a full-frame version, oh boy 😉 Any news from your friend’s GX1 ? It’s supposed to be a very competent camera as well !
And don’t worry about your influence, you can only advise, let people decide for themselves (and make such obvious mistakes, like me 😉
See you soon, I hope
Pascal
[…] The bad : no in-camera stabilisation.That’s a real shame. The IBIS on the Olympus OM-D is incredible […]
