Sony Alpha 7 and Alpha 7R camera review
Ever since Sony arrived at the digital camera business, they have been experimenting with various types of models and concepts. To name a few Sony developed the SLRs, Translucent Mirror Technology, NEX and the ones with dual auto-focus systems. There is no doubt Sony left no stones unturned when it comes to digital imaging. Sony’s latest product, the Alpha 7 and Alpha 7R will no doubt have something more exciting to offer.
Sony created full-frame cameras that are the same size as the Olympus OM-D E-M1. These are much more smaller than any other full-frame interchangeable lens camera.
It is said that Sony will be combining the Alpha and the NEX brands. This will force all the lens cameras to fall under the Alpha models.
The Alpha 7 and Alpha 7R identical to each other. The only difference is in their sensors and the auto-focus systems. The A7 models come with 24 mega-pixel CMOS, but the A7R comes with the 36 mega-pixel CMOS. The CMOS sensors do not have optical low-pass filter. You will find the AF system found on the SLT-A99 on A7 but the A7R has the regular contrast detection.
The cameras use Sony’s new Bionz X processor, supports XGA (1024 x 768 pixel) electronic viewfinder, Wi-Fi, tilting LCDs and the weatherproof body found on the Olypmus E-M1. To accommodate the full-frame sensors Sony developed new lenses. They are called the “FE-series”. It is announced that there will be initially 5 lenses and as much as 10 more will be introduced by 2015.
If you already have the E-mount lenses, they will work. However, it won’t illuminate the entire sensor. Or if you have the A-mount lenses they will also work but you have to use Sony’s adapter to make them work.
