Equipped with 24 and 36 megapixel sensors new sony cameras Series Alpha. cause interest in many potential buyers from different segments. But one question remains: what is the difference between A7 and A7R, and which of them should be chosen? Despite the similarity, there is between them a big difference In price: A7 will sell at $ 1,700, and A7R for 2300 conventional units. In this article, we will consider differences in the functions of both cameras and give recommendations for the choice of optics.

Both cameras are aimed at completely different audiences. Please note that we will conduct a comparison based on specifications. A detailed comparison with ISO sample images awaits us in the near future.

Comparative table with Sony A7 and A7R characteristics

Most of the above functions are very similar, but between Sony A7 and Sony A7R cameras exist, there are key differences that we will highlight below:

Image sensors and image quality: Obviously, sensors on both cameras are completely different. A7 is equipped with a 24.3 MP matrix, and A7R received 36.4 Mp sensor. As a result, the size of each pixel on the sensor is also different: 5.96μ and 4.87μ. What does it mean? Simply put, A7 will provide a clean image at higher ISO values, if you look at the pixel level or with a 100% increase. However, this advantage will not work when the output of both sensors will be images with a reduced or "normal" sampling frequency up to 24.3 mp. As a result, when 36.4 MP will change the size of up to 24.3 mp, the number of noise on both images will be equivalent, but the high resolution of the sensor on A7R will be better and sharper to produce small parts.

Autofocus system: Here you can expect a surprise. Sony A7 has excellent hybrid system Autofocus with the phase definition plus a contrast autofocus, while in A7R only contrast autofocus. This mainly means that the A7 will focus faster and, therefore, will become the best choicethan A7R for everything that moves (portrait, street photography). Also, A7 has much more focus points (117 against 25) for better cropping and composition. Contrast autofocus with the face recognition feature in A7R is designed specifically for landscape photos and architectural surveys.

Camera shutter and flash synchronization speed: Sony A7 comes with a shutter with electronic front curtain, while in A7R there is no such possibility. As a result, A7 has a 1/250 flash synchronization speed, and in A7R it is limited to 1/160 seconds. If you are a portraitist photographer and often use the flash, then the A7 will be suitable for you.

Examples of images

Price: Finally, there is a difference of $ 600 between these two models. This means that Sony charges an additional fee for permission, despite the fact that A7R lags behind the speed of flash synchronization and autofocus.
The manufacturer makes a sharp separation between the two new models. Sony A7 is clearly focused on everyday photo, portrait and street survey. The A7R camera is a tool that will be most useful for landscape and architectural photographs where high-resolution capabilities are more important than autofocus speed and flash synchronization speed.

We hope that this information will help you determine which camera will mostly satisfy your photographic needs.

For landscape / architectural photography using Sony A7R: With 36.4 MP sensor you need lenses that can transmit the image as detailed as possible and have a sufficient range of focal lengths. The ideal candidate will be the Zeiss 24-70mm F / 4 ZA OSS. 24mm is a fairly wide angle for most situations, and a good zoom range makes it very suitable for shooting landscapes. And the image stabilization, of course, will be a pleasant bonus in this lens. Its presence allows you to take pictures from hands in low light conditions. Sony 28-70mm f / 3.5-5.6 will not be able to compete with 24-70mm Zeiss. Sony FE 70-200mm F / 4 G OSS is another contender for shooting landscapes. Unfortunately, Sony has not yet released a super wide-angle lens, but we expect to see it in 2015.

The Japanese manufacturer Sony produces very cool smartphones. Of course, everyone has a hearing aphons, Samsungi, Xiaomi and Huavai, since these brands aggressively advertise their products and promote it in Russia. Sony advertising campaigns are softer, but the quality and functionality of smartphones is no worse, and sometimes it is better. Next - Top smartphones from Sony in descending order, that is, from above - the most expensive.

There are complaints of users that the body of the phone is thick, but it is even plus - the device is perfectly lying in his hand.

Most of the model reviews are positive, users highlight the camera, the shell optimization, an assembly, inspiring reliability and monolith. Plus, all available modules work without complaints at all: GPS, radio module, Bluetooth - no questions cause any questions. In addition, this is the first middle segment telephone with Hi-Res Audio support, so the sound is simply chic.

4th place - Xperia XZ1

What is obvious from the name, this flagship is the predecessor of the XZ2 and XZ3, it is presented at the end of 2017, but even now it is a great solution from the Japanese brand.
