ISO Accuracy

The actual sensitivity of each indicated ISO is measured using the same shots as are used to measure ISO noise levels, we simply compare the exposure for each shot to the metered light level (using a calibrated Sekonic L-358), middle gray matched. We estimate the accuracy of these results to be +/- 1/6 EV (the margin of error given in the ISO specifications). In our tests we found that measured ISOs from the Canon EOS 650D and EOS 700D match the marked ISOs within 1/6 stop accuracy, meaning ISO 100 indicated = ISO 100 measured.

Noise and Noise Reduction (JPEG)

This is our standard studio scene comparison shot taken from exactly the same tripod position. Lighting: daylight simulation, >98% CRI. Crops are 100%. Ambient temperature was approximately 22°C (~72°F).

Note: this page features our new interactive noise comparison widget. By default, we show you the default noise reduction settings of the camera tested, and three other models of the same class. You can select from all available NR options, and from other cameras. The 'tricolor' patches beneath the familiar gray/black/portrait images are taken from the same test chart, and show how noise impacts upon blue, green and red areas of a scene.

At its default ('Standard') level of noise reduction, the EOS 700D exhibits a bit more image noise than many of its peers between ISOs 1600 and 6400. Noise suppression increases dramatically at the camera's two highest ISO sensitivities. And as the samples bear out, image detail falls off significantly beyond ISO 3200.

Looking at the graph it's interesting to note that the 700D also shows higher noise levels than the EOS 600D, throughout nearly the entire range of ISO values. Yet based on the samples here, the 700D maintains a near identical level of image detail while also offering a top ISO of 25,600 (versus 12,800 in the 600D).

ACR Raw noise (ACR 7.4, noise reduction set to zero)

As you can see in the sample images here, the noise performance of the 700D remains fairly uniform up through ISO 1600, with detail retention that is on par with the Nikon D5200 through ISO 3200. The 700D does not produce as clean an image as the Pentax K-30 (which applies noise reduction to its raw files) but in terms of fine detail retention actually holds it own pretty well. Image detail does become significantly obscured though at ISO 6400 and higher.

Looking at the graph of raw file data, you can see that at the sensor level, noise performance of the EOS 700D trails just a bit behind the earlier model 600D beginning at ISO 3200. Referring back to the image samples though, it's clear that there are no meaningful differences in 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.

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.
