What Are The Key Differences Between The Canon EOS 7D And Nikon D7100?

Are you still in doubt and can’t make your decision? I will demonstrate the differences in detail. Canon EOS 7D vs. Nikon D7100 are pretty similar in some terms but also have a lot of differences. Let’s go.

Picture Quality

The Canon EOS 7D gives an 18-megapixel image file at its maximum resolution. The new chip produces high-quality images with a wide dynamic range and delivers sharp images with natural colors at both high and low ISO settings.

The Nikon D7100 DSLR camera used an APS-C CMOS sensor. It produces a 24-megapixel image file at this camera’s maximum resolution. The picture quality is standard and delivers sharp images.

In picture quality, Nikon bells the ring. More features in picture quality have been added. So, Nikon EOS 7D is the winner in picture quality.


The Canon EOS 7D uses a Dual Digic 4 processor and an 18.0MP APS-C (22.3 x 14.9 mm) CMOS sensor. It has an anti-alias filter which you can remove.

Removing the anti-alias filter improves sharpness and detail, but it also increases the likelihood of noise in some scenarios.

The Nikon D7100, on the other hand, sports a 24.0MP APS-C (23.5 x 15.6 mm) sized CMOS sensor. Compared to Canon 7D, the Nikon D7100 has a 1.1x Larger sensor area. The anti-alias filter is absent in the Nikon D7100.

If you set the same focal length and aperture, larger sensors provide the photographer greater control over the depth of focus and hazy backdrop. In that case, you can choose the Nikon D7100 to increase the size or freedom of your image cropping.

Size and Weight

The Nikon D7100 measures 136 x 107 x 76 mm on the outside and weighs 765 grams. Compared to the Canon 7D, the Nikon D7100 is 2mm thicker and 12mm narrower, and 4mm shorter.

The Canon 7D measures 148 x 111 x 74 mm on the outside and weighs 860 grams. Although the Nikon D7100 weighs 95g less than the Canon 7D, I don’t think this will make a noticeable difference.

Size and weight may be significant factors if you are willing to carry the camera all day long. In that case, Nikon D7100 is the perfect choice as you can take it more comfortably anywhere than the Canon EOS 7D.

Battery and Connectivity

The Nikon D7100 contains a headphone connector that enables you to connect external headphones and assess the sound quality while recording. The EN-EL15 battery pack in the D7100 can hold up to 950 shots on a single charge.

The Canon EOS 7D doesn’t come with a headphone port. But studio photographers will like having a PC Sync socket in Canon EOS 7D.

With its help camera controls the professional strobe lights. This camera has a very concerning battery life, with only 800 shots out of its LP-E6 battery.

The headphone connector and more battery health would be the reasons to put the Nikon D7100 on top. So, here Nikon beats Canon once again.

View finding and Interval Timer

An intervalometer is included in the Nikon D7100. Using this, the photographer can take time-lapse photos of events like a sunset, the rising of the moon, or flower budding. You don’t need to buy an external camera trigger or any associated software.

Where the intervalometer is absent from the Canon EOS 7D, the Nikon D7100 and the Canon EOS 7D have the exact optical viewfinders. The viewfinders on both cameras have the same magnification and field of vision (100 percent) (0.63x).

So, here Nikon goes further another time. The excellent intervalometer option gave Nikon a boost to win in this section.

Memory slot

The Nikon D7100 has two memory slots where you can use SDXC cards. Two different slots are handy in case one of the memory cards breaks or fails.

In contrast, the Canon EOS 7D only has one slot for memory storage. The Canon EOS 7D stores its imaging data on Compact Flash cards.

A dual storage system puts the Nikon D7100 on the top. If you want to be risk-free and want more space separately, then you should go with the Nikon D7100.


Nikon D7100 Digital Camera works with a Nikon EN-EL15, 2100 mAh Li-ion Battery. From this camera, you can get up to 950 shots per charge.

The Canon EOS 7D equips a Canon LP-E6 Lithium-Ion Digital Camera Battery. You can get a maximum of 800 pictures taken by this camera in a single charge.

You can store and shoot more pictures in the Nikon D7100 per charge. So, here Nikon D7100 wins.
