X5 iso test 100 - 25600

dopeytree · Oct 9, 2015

Shot these today nothing too technical but it's fairly low light in my lounge. Images are 100% crop from center. Exported in lightroom. Lightroom defaults 25 colour noise reduction but 0 luminence noise reduction. These results are pretty impressive. Looks good in video too! I'll try out some lowlight footage tomo.

Thank you very much for posting!
ISOvise they look not bad, I am however a little worried about the softness in all the pictures, even at the loves iso. Did you focus on the cat? If yes, there seems to be a back-focus issue, and it seems the focus plane is in the fireplace. And at what aperture did you shoot?

I think the focus may have been the fireplace / wood. Its around the open end f1.7 ish. & the lens needs calibrating I just keep forgetting to do it - you need to point it at something over 50 meters away.

Have attached the full un-cropped shot

Thank you again.
Well f/1.7 would explain the softness.
How close can this lens focus?

Those seem back to front to me. Low ISO bright image, High ISO dark image is the reverse of what I'd expect. On my DSLR the higher the ISO the more light it gathers.
