Sony unleashed the Sony A7 and the A7R in October of 2013. With the Sony A7 aimed for general use sporting a 24 MP sensor and hybrid autofocus, the A7R differs primarily with its 36 MP sensor, therefore making the A7R more suitable for specific types of photography that need high resolution such as landscape, architecture, studio and product photography. I had an opportunity to test both cameras in 2014, however, I did not have a chance to write detailed reviews for a number of different reasons. Hence, this is more of a catch-up type of a review showcasing some images from my recent trips, along with the usual analysis.
While reviewing the Sony A7 II, I had a chance to test and play with every Sony FE lens made as of April of 2015. The list includes the following lenses: Sony FE 35mm f/2.8, Zeiss Loxia 35mm f/2, Zeiss Loxia 50mm f/2, Sony FE 55mm f/1.8, Sony FE 16-35mm f/4 OSS, Sony FE 24-70mm f/4 OSS, Sony FE 28-70mm f/3.5-5.6 OSS and Sony FE 70-200mm f/4 OSS. Since I also simultaneously had the Sony A7R and A7S bodies (reviews to follow soon), I decided to measure MTF performance of each lens using Imatest and see how they perform individually. While I am planning to review all of these lenses in detail within the next few months, I thought putting together some data for our readers might be helpful, perhaps for those of our readers who either already own the A7 system, or those who are planning to invest in it. The below numbers are based on two different samples of each lens (I always do my best to test at least two due to sample variation) and the numbers I present are for the lens that showed the best results. Unfortunately, due to the shutter shock issue of the Sony A7R camera, I was not able to reliably test the Sony FE 70-200mm f/4 OSS lens, particularly at anything longer than 100mm. I will have to retest that lens when Sony adds electronic front curtain shutter feature to the A7R, or releases a newer 36 MP+ body with built-in EFCS (yes, the shutter shock on the A7R is pretty significant). I have not yet tested the newly announced Sony FE lenses, so I will test those separately as soon as I get my hands on them.
Just as I have suspected, the Sony A7 and A7R cameras are not immune to the Red Dot Flare issue, thanks to the short flange distance. The effect of the red dot flare can be significantly reduced if the rear lens element has non-reflective coating applied to it. In the case of the two below, the Zeiss 35mm f/2.8 ZA handles flare a little better due to its optical design, but the red dots are still all over the place. Both shot at f/16, pointing directly at the sun.
In this article, I will show noise performance from the new high resolution Sony A7R mirrorless camera and compare it to its direct competitor, the Nikon D800E. Both have 36 MP sensors and both lack anti-aliasing (AA) filters, which should make it a good case for analysis at pixel level with no re-sizing/down-sampling involved. The Sony A7R is a pretty hot camera right now thanks to its compact camera body, high resolution and excellent image quality. Let’s take a look at how it fares against the older Nikon D800E.
Of all third-party lens manufacturers, Korean Samyang was the first to launch a new lens lineup for the recently announced Sony A7 and A7R full-frame cameras. There are five of them – as many as Sony announced themselves, but unlike the Zeiss lenses these were not specifically designed for mirrorless cameras. Rather, they are tweaked Samyang prime lenses designed for the most popular DSLR systems and are also known as Bower, Rokinon, Vivitar and Pro-Optic.
With Sony taking over the major headlines this week, a number of our readers have been asking about the differences between the Sony A7 and A7R – two new full-frame interchangeable lens mirrorless cameras. As I have written in this article, Sony’s full-frame mirrorless cameras are shaking up the camera market and could potentially influence the future development and pricing of full-frame DSLRs in the future. Boasting impressive 24 and 36 megapixel sensors, the Sony A7 and A7R cameras are attracting a lot of potential buyers from different camps. But one question remains: what is the difference between the A7 and the A7R and which one should one pick? Although both cameras look very similar, there is a big difference in price: the A7 is priced at $1700, while the A7R is at $2300. In this article, I will go over the feature differences between the two cameras and provide personal recommendations on what lens(es) to choose. I believe the two cameras are targeted at completely different audiences. Please keep in mind that this Sony A7 vs A7R comparison is purely based on specifications. A detailed comparison with image samples and ISO comparisons will be provided in the upcoming Sony A7 and Sony A7R reviews.
Having a full-frame camera system does not make much sense unless you have lenses to go with it, too. That is why Sony has just announced five lenses to go with the recent Sony A7 and Sony A7R full-frame mirrorless cameras, and a refreshed 70-200 f/2.8 model for its Alpha line-up. What’s more, only one of these full-frame mirrorless lenses is a basic kit zoom, the rest being high-end Sony and Zeiss optics.
It has been a little over a year since Sony announced world’s first fixed lens 35mm full-frame mirrorless camera, the Sony RX1. Shortly after, Sony released another version of the same camera without an anti-aliasing filter and gave it a slightly different name – Sony RX1R, similar to what Nikon did with the D800 and the D800E. And with Sony’s hard push on the NEX-series cameras, we thought that it was a matter of time until Sony announces a full-frame interchangeable lens mirrorless camera system. Back in 2012, we predicted that Sony would release a full-frame camera in 2013 and it seems like our predictions were indeed true. Today is a very exciting day for the world of photography, because Sony has just announced world’s first full-frame interchangeable lens mirrorless camera with autofocus capabilities. Sony is shaking up the industry once again with a breakthrough product that will lead the way for others in the future. Some might say that this is the beginning of the end of DSLRs. Read on to see what we think.
Sony has just announced two cameras, which happen to be world’s first full-frame interchangeable lens mirrorless cameras with autofocus capabilities and also world’s lightest full-frame cameras – the Sony Alpha 7 (A7) and the Sony Alpha 7R (A7R). Featuring high resolution 24 MP and 36 MP sensors, a fast hybrid autofocus system with phase-detection AF, a high contrast 2.4 million dot OLED electronic viewfinder, Wi-Fi connectivity, Full HD movie recording with uncompressed HDMI output, weather sealing and a low price of $1699 (A7) and $2299 (A7R), the two cameras are meant to shake up the photography industry.
