Marco Tecno Posted April 2, 2015 Share Posted April 2, 2015 Not strictly video related, but I was stunned by this:http://***URL removed***/reviews/image-comparison/fullscreen?attr144_0=samsung_nx1&attr144_1=nikon_d750&attr144_2=nikon_d5500&attr144_3=sony_a7_ii&attr146_0=100_6&attr146_1=100_6&attr146_2=100_6&attr146_3=100_6&normalization=print&widget=212&x=-0.6624118121908348&y=-0.9768417588491292 Imo the nx1 is well ahead of others, when ev is pushed ahead. The incredible thing is that nx1 fares much better when pushing iso 100 ahead of 6ev, then in its iso 6400 mode! What do you think?

Administrators Andrew Reid Posted April 2, 2015 Administrators Share Posted April 2, 2015 The Canon sensors are so noisy. Can't be pushed as far.How much of a practical difference it makes to real photography though.... I'm not sure. Who under exposes by 6ev by mistake on every shot!?

Marco Tecno Posted April 2, 2015 Author Share Posted April 2, 2015 The fact is that with nx1 it seems to be better shooting at iso 100 with -6ev, rather than shooting at 6400 with 0ev of compensation. Much more chroma noise at 6400, less details and ugly patterns of luminance noise, looking like something going on high iso raw, like a sort of (very bad) nr.

Pavel Mašek Posted April 5, 2015 Share Posted April 5, 2015 That is very interesting! D750 is probably the best but NX1 is very close and has the better blacks... Great thing about that is you can always brings lot of informations from shadows and make HDR from every photo you take with ISO 100. But look at 6D! Just awful...

Guest Ebrahim Saadawi Posted April 5, 2015 Share Posted April 5, 2015 The Canons are not that bad overall at all. In this particular scenario, Canon sensors have a strange differerence against Nikons (the rest). Nikon sensor are essentially ISO-Less, as in shooting at 100ISO and pushing ISO in post to 6400, is the same as shooting at 6400. Like Red Raw. While Canon sernsor you MUST perform the gain increase before shooting (in-camera) otherwise pushing ISO in post is radicallty different than from in-camera... But when you shoot both a Nikon and a Canon at 6400 in-camera they look on par, even Canon has an edge in high iso DR. Something strange about how Canon sensor can be pushed so high in-camera but not after shooting. Anyone with Chip knowledge here?This phenomenon gives Nikons advantage is underexposure push-up scenarios. But it's not just when underexposing an entire image (which really on is a lab test) but when parts of the image are underexposed, so you can lift them with an invert S curve. It effectively gives an advantage in DR when you underr expose and lift up in post. Quote Link to comment Share on other sites More sharing options...
jcs Posted April 5, 2015 Share Posted April 5, 2015 Canon has variable analog gain on the sensor. It appears the other chips have fixed analog gain which is optimized for the best noise performance. Quote Link to comment Share on other sites More sharing options...
