Noisy at what ISO? I find that up to ISO 800 it is fantastic.

ISO noise has (almost) nothing to do with lens. Slow lens does require you to up the ISO to keep good exposure, but that's it. Good exposure is the trick (not up exposure in post).

Thanks guys, not underexposing or would obviously expect the noise, not lifting, crushing the blacks if anything, not enabled iDynamic, will try with CinedD, thanks for the tip.

Hmmm, I didn't expect this much noise, more than GH3 or hacked GH2 and neat video great as it is makes it smudgy so would rather have no noise when it's supposed to be properly exposed, but hopefully i'll learn more to keep it under control, only just started with it. Either that or it's something else for ebay and I'll pay the more for the A7s.

@belfryman

Are you using 2k or4k? 4k has very fine grain and when downsampling and adding NR in post it looks quite OK. Shadow +2 adds noise too. cineD is not good in low light. I use natural contrast from -5 to -2 and i dont usually dial color down. Do you use 0-255 or 16-235? If using 0-255 it should be viewed or edited accordingly.

This is a frame grab, kind of posterized on the leaf, then the robins cleaned up, to be fair they all look a bit gloomy. The dragonfly with and without neat.

I've darkened down the shots as well, should have taken the little grade off but you get the idea, literally just ran down to the gardens here, yes they do sell pots that pukey lilac colour!

@Superset yes, they look very dull to me now but were showing fine on the meter and i have darkened them down and then they're crushed down but I agree.

flower no grade. @Vesku Thanks, I'm on an imac with a second monitor dell U2413. Should I stick to 16-235? I'm only using FCPX, still waiting for myself to learn Resolve!

And shop, not sure it's so much underexposed as everything dialled to -5. This looks really noisy to me, in the box at the front, on the brown wall at the left, on the floor to the left of the metal cannister in the foreground, the pot shadow, basically anywhere that is a bit darker there's no forgiveness, it all goes murky like pre hack GH2 so to get anything without noisy areas it's all got to be perfectly lit or covered in daylight. But as I say it's probably cos I'm just not used to it and I need to make sure things read slightly overexposed to be safe.

The GH3 seemed a lot less noisy. Anyway, apologies for thread hog! Over and out. Thank you. @Vesku you're it is all underexposed, I think I'll keep the historgram on for a bit!

Glad you said it is noisy, it just seems the circumstances in which I can get clean footage have been reduced, which is just good to be aware of. I do basic grading, just in FCPX, I took it off to make it clearer, not had time to learn Resolve, but think I will put things back to -2 now and refer to the histogram more till I've got more of a feel for it. I just thought, woah, this needs a lot more managing than before. Just need to get used to it. Thanks again.
