Ok, you have a point. And I even agree with you. IBIS on legacy tele(!) lenses and for video mode is a big short-coming on the Nex, for which the Oly get kudo points. But as to your claim that the Nex is useless in low light, I am not so sure.
Also, your point is a technical one, imo. Not mine - I am going by experience of the Nex-5, Nex-5N and now Nex-7.
I am very curious to see the comparisons between Nex and the Oly, where the ISO200-400 shots with IBIS beat the Nex with ISO3200. I believe you, but ISO3200 and 1/20th of a sec is extremely low light. See e.g. last pic below.
Just how dark do you want to shoot exactly?
Let me make my point: the Nex is a great low light shooter and I speak from experience, as the rest of this post will try to illustrate. Technically your point may be very valid, and I am very willing to accept it. Practically, I see no need to switch cameras for low light ability - I am getting plenty of satisfactory shots with the Nex.
I don't really care 'technically' about which is better - you can have it your way. I am merely trying to point out that numbers are just numbers - practice tells more. Again, I am looking at my darkest pictures, and have no problem getting satisfactory shots.
First example: inside a church with the non-IS E24 at f/1.8. You can see all the candles in the church that were lit, and this was all the light available. The camera took the shutter time up to 1/60th at f/1.8 and ISO 1000.
Second example is a silly example that was a view from the apartment at night. The first shot, at 1/5th of a sec and ISO 3200 at f/2 mimics a little what the view was like, but the real view was actually a bit darker. You can tell from the lit sky
-this is at night- the sky is really supposed to be dark.
I took these shots to test HHT, Night-scene and A and P mode - see the subsequent images. But shots like these are extreme, imo. As test-shots they are fine, as real shots, I am not so sure.
The next shot - a crop with the 50mm - I included, to show a more typical 'low light' shot. The 'silly' Nex did not account for OSS, it happily shot ISO to 3200 and 1/80th, whereas ISO 400 at 1/20th would have been a better choice indeed. Even so, this type of lighting works fine hand held on a Nex.
Which repeats itself in this scene - trying to compare OSS versus non-OSS, but the camera keeps acting as if no OSS is present on the E50 versus E24:
And finally a handheld 50mm shot where the OSS did matter:
And find some more non-OSS low light shots with the 24mm lens here:
Again, I am not trying to prove one camera over another. I am merely putting context on your 'superior' way of claiming a 'best'. To me, the larger sensor has benefits that I care about and drawbacks that I work around. To others this may be different. If you can't get the best out of a Nex and use a different camera instead, that is your prerogative.
And please leave the personal attacks aside - we have seen enough of those in the past here.
I used the Nokton 35mm 1.2 with the NEX5N. I am selling the 35/1.2 and am moving to shooting lowlight with the EP-1 & 25/0.95 COMBO ONLY.
Unstabilized ISO1600 at the border of hand-holdability or at least 1/1.5xFL exposed ISO3200 from the NEX5N doesn't touch stabilized ISO200-400 on the two years old Oly. Sorry, but thanks for trying.
The newer sensor plus the better IBIS in the coming Olympus camera will wipe the floor with the lowlight abilities of the NEX line with any existing lens attached. Theoretically, only the 5N with the SEL 50/1.8 will be able to challenge it, but probably not, because F/0.95 paired with only the half length FL of the Voigtlander compared to the 50mm and the 1+2/3EV light lost because of the smaller 1.8 aperture gives you in real life light loss resulting in almost two times higher ISO for the NEX in lowlight.
And no. No NEX camera has that great output compared to the superior otput that I saw in the above comparison's samples. I tried and use the IBIS in the Oly and also the NEX line. I do not theoretize about something I do not have.
I am providing my experience, which I have no duty to defend. You can take it or leave it. I have no lust to waste time with some graphical explanation for the non-believing trollnamer. I shoot wonderful photos, and you spend time expanding your knowledge, not beliefs. NEX theoretician:>
