What To Know
- Crop-sensors have a smaller physical size compared to full-frame sensors, resulting in a narrower field of view and a higher magnification ratio with the same lens.
- EF-S lenses are designed specifically for crop-sensor cameras like the 7D Mark II and provide a wider field of view compared to EF lenses on a full-frame camera.
- If you require full-frame image quality, better low-light performance, and a wider field of view, the 5D Mark III is a more suitable option.
For wildlife photographers, choosing the right camera is crucial for capturing breathtaking shots of elusive subjects in their natural habitats. Two of the most popular options for wildlife photography are the Canon 7D Mark II and the 5D Mark III. Both cameras offer exceptional features, but they differ in several key aspects that can impact your shooting experience. This comprehensive guide will delve into the strengths and weaknesses of each camera, helping you make an informed decision based on your specific needs and shooting style.
Sensor and Image Quality
The Canon 7D Mark II features a crop-sensor, while the 5D Mark III has a full-frame sensor. Crop-sensors have a smaller physical size compared to full-frame sensors, resulting in a narrower field of view and a higher magnification ratio with the same lens. This makes the 7D Mark II ideal for capturing distant subjects or framing tight shots. However, full-frame sensors provide a wider field of view and better low-light performance due to their larger surface area.
In terms of resolution, the 5D Mark III has a slight edge over the 7D Mark II, with 22.3 megapixels compared to 20.2 megapixels. This difference is noticeable when cropping or printing large images. Both cameras offer excellent image quality with accurate colors, wide dynamic range, and low noise levels.
Autofocus Performance
Autofocus is critical for wildlife photography, as subjects can move quickly and erratically. The 7D Mark II boasts an impressive 65-point autofocus system with 19 cross-type points. This provides fast and accurate focusing, even in low light conditions. The 5D Mark III has a more modest 61-point autofocus system with 41 cross-type points. While still capable, it may struggle in situations where the subject is moving at high speeds or in low-light environments.
Burst Shooting Speed
Capturing a series of consecutive shots is often essential for capturing the decisive moments in wildlife photography. The 7D Mark II excels in this regard, with a burst shooting speed of up to 10 frames per second (fps). This allows you to capture fast-moving subjects or multiple frames of action in rapid succession. The 5D Mark III has a slower burst shooting speed of 6 fps, which may be limiting for photographers seeking to capture fast-paced action.
ISO Performance
When shooting in low-light conditions, high ISO performance becomes crucial. The 5D Mark III has a native ISO range of 100-25600, expandable to 50-102400. This provides greater flexibility for shooting in dim environments and capturing subjects without using a flash. The 7D Mark II has a native ISO range of 100-16000, expandable to 50-51200. While still impressive, it may fall short in extremely low-light situations compared to the 5D Mark III.
Weather Sealing and Durability
Wildlife photography often involves shooting in harsh outdoor conditions. Both the 7D Mark II and 5D Mark III are weather-sealed to protect against dust and moisture. However, the 7D Mark II has a more rugged construction with a magnesium alloy body that provides better protection against impact and extreme temperatures. This makes it a more suitable choice for photographers who frequently shoot in challenging environments.
Lens Compatibility
The choice of lenses available for each camera can impact your shooting options. The 7D Mark II is compatible with Canon’s EF-S and EF lenses, while the 5D Mark III is compatible with EF lenses. EF-S lenses are designed specifically for crop-sensor cameras like the 7D Mark II and provide a wider field of view compared to EF lenses on a full-frame camera. EF lenses, on the other hand, are compatible with both crop-sensor and full-frame cameras, offering a broader range of options.
Verdict: Which Camera is Right for You?
Choosing between the Canon 7D Mark II and 5D Mark III for wildlife photography depends on your specific shooting needs and preferences.
- If you prioritize fast burst shooting speeds, superior autofocus performance, and a smaller form factor, the 7D Mark II is an excellent choice.
- If you require full-frame image quality, better low-light performance, and a wider field of view, the 5D Mark III is a more suitable option.
Ultimately, both cameras are capable of producing stunning wildlife images, and the best choice for you will depend on the factors that are most important to you.
