mzisb Posted March 9, 2007 Share #1 Posted March 9, 2007 Advertisement (gone after registration) Could not sleep last night so I did a high iso comparison in my untidy kitchen between my M8 with the old 50 mm 1.4 and a 5D with EF 24-105. Of course you cannot compare these lenses but it helps a little bit to understand. Image 1: M8 shoot as DNG and converted with a standart Capture one process. Image 2: M8 same DNG but with low noise reduction in Capture one. Image 2: 5D shoot as jpeg high no work at the file. The M8 is very sharp even if you use noise-reduction. But I like more the image with no noise- reduction. regards Michael Welcome, dear visitor!

Guest sirvine Posted March 9, 2007 Share #2 Posted March 9, 2007 Before I drive myself completely insane, is there actually any difference between the fifth and sixth images that you posted? Also, I'd love to see a 100% crop of that plant on the sill. Link to post Share on other sites More sharing options...
rami G Posted March 9, 2007 Share #3 Posted March 9, 2007 why do you shoot the 5D on jpeg? Link to post Share on other sites More sharing options...
tashley Posted March 9, 2007 Share #4 Posted March 9, 2007 And I'd like to know which ISO you used! Tim Link to post Share on other sites More sharing options...

Both at 1250 and 2500 using C1 with no noise reduction or sharpening except for a bit of chroma noise reduction. I find that the 5D is at least one stop better than the M8. However, the 50 lux is so sharp that the files do respond pretty well to noise reduction like Noise Ninja. This is after the latest firmware as well.

Guest sirvine Posted March 9, 2007 Share #8 Posted March 9, 2007 deltoid, That seems about right, based on the test above. Setting aside the obvious differences in WB and saturation, etc., the 5D shot looks a whole lot like the M8 with noise reduction turned on. While a lot of people can't deal with the "noisy" version of M8 RAW, I don't know why anyone wouldn't prefer the option to apply their own NR algorithm (or not, if they prefer) instead of whatever the in-camera options allow. That said, the 5D does seem to be a triumph of Canon's unique skills. Link to post Share on other sites More sharing options...
johnastovall Posted March 9, 2007 Share #9 Posted March 9, 2007 Shooting the 5D as jpeg is rather pointless isn't it? Shot it in raw and process in C1. Link to post Share on other sites More sharing options...
johnastovall Posted March 9, 2007 Share #10 Posted March 9, 2007 Shooting the 5D as jpeg is rather pointless isn't it? Shot it in raw and process in C1. Also the Canons work best at for high ISO at full numbers 1600, 3200. Link to post Share on other sites More sharing options...
Jamie Roberts Posted March 9, 2007 Share #11 Posted March 9, 2007 I myself have tested my 5D against the M8.

The 5d is actually faster than its rated ISO, so what you usually get is a slightly better exposure (and therefore less noise). But the 14bpp AD conversion in the M8 actually gives you many levels more detail on the shadow end, again, given a decent exposure. You should try this, if you still have your M8. Move the auto EV compensation to + 1/3 when shooting hi ISO stuff. You'll see a noticeable increase in detail, less noise, and more ability to push and pull the shot. Having said all that, the 5D at 1600 ISO is more than a match in terms of noise than the M8 at 2500. It's just as sensitive, and way less noisy... though if you try to open up the shadows in an underexposed area they will be mush on the 5d. Link to post Share on other sites More sharing options...

This is my experience also Jamie - the ONLY negative reason I had for looking for an alternative to my 5d (apart from weight and size) was this mushiness of shadow detail at higher ISO. As you say, there is a great deal more in an M8 file. Tim Link to post Share on other sites More sharing options...
barjohn Posted March 9, 2007 Share #13 Posted March 9, 2007 Could someone that has both shoot a Gretagmacbeth color chart as well as some objects with both so we can see the difference? Just ISO 1250/1600 and 2500/3200. Then where there is shadow show us what happens when you pull up shadow detail. It is hard for those of us that don't have a 5D to follow this wihtout images.
