Canon EOS 5D Mark 2 ISO Racket Comparison
Following are two extensive 100% crop comparisons between the 5D Ii and several other Canon EOS camera bodies. If you take read any of the site’s other recent Catechism EOS DSLR camera reviews, you volition recognize the following colour block test that clearly shows and compares sensor noise.
Read about the Camera ISO noise tests in the help section to learn more nearly the tests and how they are conducted. A key take-away from that folio is that racket reduction is completely off unless otherwise specified.

Dissonance is a very difficult characteristic to compare and to put a number on. It has size, shape, quantity, brightness, color … and dissonance reduction can be done at any point in the image processing pipeline. Applying noise reduction reduces the amount of noise in an image – normally at the cost of image sharpness/details. As I’ve said before, my personal preference is for the camera to allow me to choose the amount of racket reduction applied during post processing of RAW images. I usually opt for no NR until ISO 1600 or so and and then select a depression NR setting until the highest ISO settings are reached.
I’ve spent fashion too many hours looking at these comparisons, only hither are some of my observations.
Since I’ve already made comparisons to the 1Ds Mark III, I’ll continue comparison the 5D II image quality against this body. I’ve already established that these two bodies take similar resolution and sharpness – at ISO 100. In the colour nautical chart comparison, the 5D II shows a small advantage over the 1Ds III in the racket category. In the fabric example (from same shots as the color nautical chart), ISO 400 and 800 appear identical between these two bodies. At ISO 1600 and 3200, the 5D Two samples announced sharper – just likewise announced noisier. A small amount of noise reduction added to the 5D II images would probably equalize this difference. Obvious in this comparison are the three additional stops of loftier ISO settings available in the 5D 2. For my taste, the terminal two ISO settings (12800 and 25600) are for emergency use only. ISO 6400? I’ll avoid it, but information technology is usable – specially if the resulting image is downsized.
Comparing ii cameras with different resolutions is non easy. And there are many means to brand the comparison. Thus, I have provided samples from the native resolution of the Canon EOS 5D and the Catechism EOS 5D Mark II likewise as samples from both resized to the other body’s resolution. Even the method of resizing and the corporeality of sharpening applied can affect the results. So, in this case, I simply used Canon’s standard – Digital Photograph Pro – for creating these samples.
For my eyes, the 5D II delivers patently more than resolution and/or less noise. At their native resolutions, racket results from both cameras are very similar with the 5D having slightly less noise at ISO 3200. The 5D II shows much more than detail in the fabric. Upwards-size the 5D images to the 5D Ii dimensions – noise characteristics are enlarged and sharpness suffers. Detail is non magically created past this process. Downwardly-size the 5D Two images to the 5D dimensions and the comparison is closer. The biggest 5D Two advantage in this comparison is lower noise levels. Thus, even if the 12.viii mp images from the 5D are large plenty for your purposes, the 5D II is withal going to deliver better image quality at this final image size – especially at high ISO settings. I call back 5D owners will be especially happy with the increased 5D 2 resolution. I’ll add that in-photographic camera loftier ISO noise reductions can now exist applied to 5D II JPG images and of course RAW images tin can be tweaked as desired during mail processing.
The comparison samples clearly show the 5D II equally a significant upgrade in image quality from the 50D (the advantage is not lost in the price of course). The 5D Two’due south images are noticeably sharper and bear witness more detail. The 5D II has noticeably lower noise levels – and the 50D’s ISO 12800 makes the 5D 2’s ISO 12800 look good.
As fabricated obvious by the above comparisons, the 5D Marking Two includes 2 sRAW (small RAW) formats. The primary reason to employ these is to get reduced file size while retaining RAW post-processing options. The original, moderately detailed RAW images for the in a higher place samples vary greatly in size among photographic camera bodies and the 5D benefits in this regard in that information technology is not storing 14-bit information (a 5D image quality disadvantage).
