The Canon EOS 7D and 70D are Canon’s most advanced APS-C format digital SLRs. Both aimed at enthusiasts and experts, both offer high continuous shooting speeds and full HD movie modes, and they even share the same battery!
But there are some key differences. The EOS 7D was launched way back in September 2009, while the Canon EOS 70D is almost four years younger, first appearing in July 2013.
The EOS 7D was undoubtedly ahead of its time, but has the newer and cheaper EOS 70D overtaken it? The photo management and Canon Project1709 experts at Photoventure in their Canon EOS 7D vs 70D comparison.
Canon EOS 7D vs 70D: 01 Sensor
They may appear almost identical in terms of specification, but the EOS 7D and EOS 70D have different sensors. The 20.2-megapixel sensor in the 70D may offer only a small increase in resolution over the 18-megapixel sensor in the 7D, but it’s a newer-generation chip which offers a higher maximum ISO and Canon’s brand new dual-pixel CMOS AF system.
Canon EOS 7D vs 70D: 02 Processor
The EOS 7D uses dual DIGIC 4 processors to provide its high continuous shooting speed, while the 70D uses a newer DIGIC 5+ processor. In practice, the older camera still has a speed advantage over the newer one.
Canon EOS 7D vs 70D: 03 Continuous shooting
The EOS 7D has a continuous shooting speed of 8 frames per second. That was excellent at the time of its launch and is still good today. The EOS 70D, however, almost matches it, with a continuous shooting speed of 7 frames per second.
The 7D’s advantage goes slightly deeper, though, since it has a much larger memory buffer capacity. It can capture 130 JPEGs or 25 RAW files in a single burst, whereas the newer EOS 70D can capture only 65 JPEGs and 16 RAW files.
The difference in continuous shooting speed is relatively small, but the difference in buffer capacity will make a significant difference if you shoot a lot of high-speed action.
Canon EOS 7D vs 70D: 04 Maximum ISO
Improvements in sensor technology mean that the EOS 70D offers a 1EV increase in maximum sensitivity over the EOS 7D, going up to ISO 12,800 in standard mode and ISO 25,600 in expanded mode. This compares with ISO 6,400 and ISO 12,800 (expanded) for the EOS 7D.
