More than ten years ago today, in 2013, Sony launched the Alpha A7 and A7R, heralding the onset of a mirrorless revolution that would reshape the camera market forever. The following year, Sony introduced the A7 II, marking the second iteration of the groundbreaking Alpha 7 series.
On October 16, 2013, Sony made history by unveiling the world’s first full-frame mirrorless cameras, the Alpha A7 and Alpha A7R. This groundbreaking announcement marked a pivotal moment in the evolution of digital photography and set off a chain of events that reshaped the camera market landscape. But what exactly were the A7 and A7R, and how did they come to fruition? More importantly, why did they matter, and what legacy have they left behind?
The Alpha A7 and A7R represented a bold departure from traditional DSLR technology, offering photographers the compactness and versatility of a mirrorless design combined with the image quality and performance of a full-frame sensor. This fusion of innovation and quality catapulted Sony into the forefront of the camera industry, challenging established players and paving the way for a new era of photographic possibilities.
With their compact yet powerful bodies, advanced features, and exceptional image quality, the A7 and A7R garnered widespread acclaim from professionals and enthusiasts alike. Their arrival signaled a seismic shift in consumer preferences, with photographers increasingly gravitating towards the mirrorless format for its portability, versatility, and cutting-edge technology.
Short Comparison Of A7 and A7R Cameras
The Sony A7 and A7R cameras are both part of Sony’s Alpha 7 series of full-frame mirrorless cameras, but they have some key differences:
- Resolution:
- The A7 features a 24.3-megapixel sensor, providing a balance of resolution and low-light performance.
- The A7R, on the other hand, boasts a higher resolution with a 36.4-megapixel sensor, offering greater detail in images.
- Low Pass Filter:
- The A7R does not have an optical low pass filter (OLPF), which can result in slightly sharper images but may also increase the risk of moiré patterns in certain situations.
- The A7 includes an OLPF, which helps reduce the occurrence of moiré patterns but may slightly reduce overall image sharpness.
- Autofocus System:
- The A7 features a hybrid autofocus system with 117 phase-detection points and 25 contrast-detection points, providing fast and accurate focusing performance.
- The A7R also utilizes a hybrid autofocus system but with 25 contrast-detection points only, which may result in slightly slower autofocus compared to the A7, especially in low-light conditions.
- Price:
- Generally, the A7R tends to be priced higher than the A7 due to its higher resolution sensor and omission of the low-pass filter.
- Intended Use:
- The A7 is designed to be a versatile all-around camera, suitable for various photography applications including portraits, landscapes, and street photography.
- The A7R, with its higher resolution sensor, is more geared towards photographers who require maximum detail and sharpness in their images, such as landscape, architecture, and studio photographers.
Introducing Sony A7 II
The Sony A7 II, introduced in November 2014, emerged as the second iteration of Sony’s groundbreaking Alpha 7 series. Building upon the success of its predecessor, the A7 II brought significant improvements and innovations to the mirrorless camera market.

Is the Sony A7 II a Good Option For Wildlife Photography?
While the Sony A7 II can be used for wildlife photography, it may not be the most ideal choice compared to other models in the A7 series, particularly the Sony A7 III. Here are some considerations:
Autofocus System
The A7 II features a hybrid autofocus system with 117 phase-detection points and 25 contrast-detection points. While this autofocus system is decent, it may not offer the same level of speed and accuracy as the more advanced autofocus system found in the A7 III, which has 693 phase detection and 425 contrast detection points.
Burst Speed
The A7 II has a burst shooting speed of up to 5 frames per second, which may be sufficient for some wildlife photography scenarios but could be limiting for capturing fast-moving subjects or action shots. The A7 III offers a faster burst speed of up to 10 frames per second, providing more opportunities to capture decisive moments.
Image Stabilization
The A7 II features 5-axis in-body image stabilization, which can help reduce camera shake and blur when shooting handheld, especially at slower shutter speeds. This can be advantageous for wildlife photography, particularly when using telephoto lenses to capture distant subjects.
Battery Life
The A7 II has a relatively modest battery life compared to newer models like the A7 III. Depending on the length of your wildlife photography outings and the availability of power sources for recharging, you may need to carry extra batteries to ensure uninterrupted shooting.
Image Quality
The A7 II’s 24.3-megapixel full-frame sensor delivers good image quality, but it may not offer the same level of detail as the higher-resolution sensors found in the A7R models. However, the A7 II strikes a balance between resolution and low-light performance, making it suitable for a variety of wildlife photography situations.
While the Sony A7 II can certainly be used for wildlife photography, photographers may find that the more advanced features and capabilities of the Sony A7 III better suit the demands of this genre, particularly in terms of autofocus performance, burst speed, and battery life. If the A7 II fits within your budget and you’re willing to work within its limitations, it can still produce excellent results for wildlife photography with the right technique and approach.
