High ISO noise and detail

High ISO noise reduction settings

The EOS 700D boasts an extra stop of ISO sensitivity compared to the EOS 600D, with in-camera noise reduction settings that have been tweaked sightly, as you can see on the noise performance page of this review. And for the most part, the 700D maintains the well-considered balance between noise suppression and detail in JPEG mode we're used to seeing from Canon's entry-level DSLRs.

The one minor exception to this occurs once you venture beyond ISO 6400. As you can see from the shape of the graph on the noise performance page of this review, the 700D switches to a more aggressive approach to noise suppression at ISO 12800. The real-world ramification is that in some instances, this heavier-handed approach can obscure a bit more fine detail at the default NR setting. Below we've shot a low light scene at ISO 12800 in order to compare the 700D's NR settings. For a look at the 700D's multi-shot NR mode, see the image quality tests page of this review.

ISO 12800 NR Standard (default) NR Low 100% crop
NR Standard 100% crop NR High 100% crop

In the crops above, you can see that at ISO 12800 very fine detail like the mesh netting begins to be smeared away at the default NR setting. And for this detail loss, neither of the two higher NR settings are reducing the appearance of chroma noise to any greater degree. As such, we'd suggest that when you do find yourself shooting at such a high ISO, you can hold onto slightly more detail by using the 'NR Low' option.

Compared to Nikon D3200

On the noise performance page of this review we've measured noise performance of the EOS 700D/650D against its peers in our studio test scene. Here we provide you with a real world comparison of high ISO performance using a still life scene. It was shot under low color-temperature (approx. 2600K) artificial light, designed to be representative of typical indoor lighting. This accentuates the appearance of noise due to the low level of blue light in the spectrum of the light source. And to achieve accurate white balance the blue channel has to be amplified strongly, and the green channel to a lesser extent - thereby increasing the visible noise.

These images were shot on the 650D, but the 700D gives identical image quality. Both 650D and D3200 cameras were shot at ISO 6400 in Raw mode and the files were processed via ACR 7.1 with sharpening and noise reduction both set to '0'. The D3200, which boasts a higher resolution of 24MP (versus 18MP for the 650D/700D) was downsampled using Photoshop's Bicubic algorithm to match the pixel width of the 650D. Identical amounts of low-radius sharpening were then applied to all both images in Photoshop.

Canon EOS 650D
ISO 6400 ACR 7.1 Raw
Nikon D3200 (downsampled)
ISO 6400 ACR 7.1 Raw
NR Standard 100% crop NR High 100% crop
NR Standard 100% crop NR High 100% crop
NR Standard 100% crop NR High 100% crop

Looking at the samples above, the EOS 650D (and thus the 700D) compares very favorably against the Nikon D3200. While the 650D/700D shows greater chroma noise in areas of solid black, it also retains a touch more color saturation. Other than that though, there is very little to separate these two APS-C cameras in terms of detail retention.

How is it that the 550D scores higher than this camera? Even in the compare to score section, raw scores higher on the 550D. I find it weird that a camera 3 generations newer scores worst.

My girlfriend sold her 550D and wants a new touchscreen Canon, but it feels like the quality has not moved ahead in years.

The score, as you can see by the review, takes into account not just the performance of the gear itself but also it's performance when compared to the others in the same range, below and above.

So, when 550D was launched for example, its features were, overall, considered better than average in a way that it scored a gold award of 77%.

This model however, has shown many good features too but a few (irrelevant for me) not so good features when compared to average.

Yet, 77% to a 76% in my opinion, in this case, is a absolutely irrelevant difference.

Its a good camera.

I am graduating from a bridge camera to a DSLR. Have been a hobby photographer for many years primarily doing landscape photography but I do it only when on a vacation that would be twice a year. I was a little confused whether to buy a Canon 700D or a Nikon D5300. I have always used Canon cameras before and after going thru many reviews comparing the two cameras I am not wiser. I also understand that once one buys a DSLR one continues to buy cameras of that family so that it can save money on lenses. Assuming that the quality of photos is not much different in the two cameras is the touch screen in 700D so useful that I should buy a Canon or the WIFI-GPS so important in the Nikon. As there anything else that help me decide between the two. Your advice would be most helpful.Tx. You can reply directly on my mail - drkpsanghvi@gmail.com

since u have been using canon , it is better to go for 700d as u r familiar with canon system and picture style and may have canon lenses with you. i find canon 700d is nice cam with cleaner sharper image with better color than nikon.

Nikon always have bean a crap for landscapes...I mean in case we talking about cheaper model DSLRs. Nikons green color is absolute joke and ISO stuck ....stay with canon...Nikon is great for moving objects r portraits...but as a landscape photographer I will never ever go for Nikon unless I can buy D4.

canon 600d or 700d ?
i have been carefully seeing 1000s of photos taken by 600d and 700d on flickr and other review sites including this top cam site, in review images 600d looks better on most parameters notably sharpness and color but on flickr photos 600d pix looks a bit less sharp to 700d pix which is more evident on night landscapes shots.
Especially a few shots on 700d plus canon 18-135 of hongkong night landscape is very sharp with great color...which none of nikon, sony or pantex match...i m in dilemma , can the 600d with 18-135 canon match 700d?
experts are requested to clear the doubt, thanks!

An outstanding review as usual. I just wish camera makers would let cameras be cameras and camcorders be camcorders. All I want is a camera. Take away the video mode gubbins and we would see a big drop in price. I can buy a pocket camcorder if I need urgent video. Why stick it in a camera at all? Better buffers could be included and also better features by knocking out the video stuff. Well, that's what I think anyway.

blah blah blah ..cannon stays cannon ..all the new shiny freaks will rush on buying a camera that is basically the same as the one they had 3 years ago .
no true innovation from cannon for a long while now .

just for once i wish they would atleast try to innovate something new

A nice camera that replaced my 600D after it ingested yellow steam on a volcano!
The camera does everything I ask of it including astro photography, and the touch screen is used far more than I thought it would be, all in all an excellent camera.
