SL1 ISO Test Photos (1600-25600)
May 7, 2013

I posted this in another thread, but here are the full size JPEG's.  And once again, I'm open to suggestions if there are any better methods to doing a test like this.

ISO 1600

ISO 3200

ISO 6400

ISO 12800

ISO 25600

I'd be interested to see how it compares to the T5i/T4i. We know it is a different sensor with respect to AF but is it different when it comes to IQ and high ISO noise?

You can inspire here in DPR camera reviews, as to test shots. Maybe some subjects with lot of details, fur, portait would be a benefit?

What  an effort and perfect work you did for us, many thanks. That's why I hate to comment, that the reprobox surface itself is very misleading IMHO as it has noise by nature.

Very true, criticism well taken! I should have put something different in the center of the frame so the 1:1 view is better served.  I'll see if I can re-create something tonight and post here.

Did another batch here at work with my 60D and then the SL1 with the same scene.  This is ISO 200 and 1600-12800 for the comparison, as that's the highest the 60D can go. The center of the frame sits squarely on the steadicam vest, so it should be nice and smooth. Also added some fur, as suggested.

60D ISO 200

SL1 ISO 200

60D ISO 1600

SL1 ISO 1600

60D ISO 3200

SL1 ISO 3200

60D ISO 6400

SL1 ISO 6400

60D ISO 12800

SL1 ISO 12800

And for the hell of it... SL1 ISO 25600

Thanks for sharing those.  The noise shows up more when the lighting isn't as bright.  That's why (at times) we should push the ISO level up in bright lighting to gain more depth of field and faster shutter speed.

You might want to post it again, as you did the first time.  But you might want to eliminate the extremely bright sections.

It's hard to compare since the 60D shots seem to be focussed closer to the camera, but based on what I see I'd say they seem generally a tiny bit cleaner.

I think I've got this round as close to controlled as possible with some fine tuning to the focus this time rather than relying on the autofocus.

60D - ISO 200

SL1 - ISO 200

60D - ISO 1600

SL1 - ISO 1600

60D - ISO 3200

SL1 - ISO 3200

60D - ISO 6400

SL1 - ISO 6400

60D - ISO 12800

SL1 - ISO 12800

I see virtually no difference between them. Why would the 60D be cleaner when its got a very similar sensor and an older processing engine?

I don't own either of those cameras, btw.

It's nice to say that nice pictures are nice.

Very nice work!

I see the cleaner images from 60D, but SL1 has more detail and sharper images. I prefer the output from the SL1. While the 60D has strong noise reduction application, so the images are smooth and less detail.

Yeah, they're better to compare. What do you think from comparing this set?

Yep, it's that small, and might come down to what kind of noise you notice most.

Why would the 60D be cleaner when its got a very similar sensor and an older processing engine?

Consider all the factors between the light hitting the sensor and the perceptions of multiple isolated viewers... then consider the effects of any differences in those factors between the two systems...
