While I loved the image unique from the NEX-5N, its AF performance was a bit sluggish, certainly not anywhere close to the Nikon 1 series cameras. Sony revamped the NEX-5 series with the 5R, introducing its first hybrid AF system that uses both phase and contrast-detect AF khổng lồ acquire focus, added WiFi connectivity options và a couple of other layout/control tweaks, making the NEX-5R a compelling option for new and existing owners. In this Sony NEX-5R review, I will go over the features và capabilities of the camera and compare it to other mirrorless options, including the Nikon 1 J2, Olympus OM-D E-M5, Canon EOS M, Sony NEX-F3, NEX-6 & NEX-7 series cameras.

Sony currently offers four mirrorless cameras of different levels: NEX-F3 (entry-level), NEX-5R (mid-level), NEX-6 (advanced) & NEX-7 (professional). Aside from price, the difference between these camera models is features & exterior design. Both the NEX-F3 & the NEX-5R are available in different colors, while the higher-end NEX-6 & NEX-7 are only available in black. Unlike the NEX-6, which is a new camera segment for NEX series in 2012, the Sony NEX-5R is now in its third iteration. Once again, Sony pushed a number of great new changes và features to this line, making it even more attractive when compared lớn previous models. Let’s take a look at the camera specifications & see what has changed since the NEX-5N.NEX-5R + E 24mm F1.8 ZA

Sony 16.1 MP Exmor Sensor
One of the most important attributes in a digital camera is its sensor – the heart of the camera that is responsible for capturing images. The Sony NEX-5R features a slightly modified 16.1 MP Exmor sensor (see the Hybrid AF section below) from the NEX-5N, which has a great balance of resolution and noise. This particular sensor has been quite famous in the photography world today – Sony uses a variation of the same sensor on three of its NEX cameras + other SLT cameras, and it sells the sensor khổng lồ other manufacturers lượt thích Nikon & Pentax as well. For example, both the Nikon D7000 and the Pentax K5 use this sensor. In fact, pretty much any 16 MP APS-C camera (except for Canon) you find on the market today most likely uses it.
The biggest advantage of the Sony NEX-series mirrorless cameras compared khổng lồ other mirrorless cameras on the market such as Micro 4/3 và Nikon 1, is the physical size of the sensor. The 23.5×15.6mm APS-C sensor is currently among the largest sensors used in mirrorless cameras. Large sensor kích cỡ means larger pixel size, which translates lớn better low-light (high ISO) performance và better dynamic range. Sony picked the same 1.5x crop factor APS-C sensor kích cỡ that is used in their “SLT” camera line, which is bigger than Canon’s APS-C sensors with a 1.6x crop factor và about the same as Nikon’s DX sensors. Here is a chart that summarizes sensor kích cỡ differences (courtesy of Wikipedia):
Another big advantage of a larger sensor is smaller depth of field, which translates to better opportunities khổng lồ isolate subjects from the background – an important factor for many photo enthusiasts và pros out there. Coupled with fast prime lenses like the Sony 50mm f/1.8 OSS, one could capture creative photographs with beautiful bokeh – something that is hard to lớn achieve on small sensor cameras.

At the same time, a larger sensor requires a bigger image circle from lenses, which negatively impacts the form size requirements of both lenses & the lens mount (read more on this below).
