The materials:
The body of the 5R is almost everywhere made of metal. You notice it when it is cool touches everywhere. When 5T is only the front plate with the lens mount of metal. The rest is like to suffer cuts and now consists of a fully plastic. In itself not bad, but it is mentioned nowhere except in the magazine Chip. The upper wheel is at the 5R when turning a nice rattle of itself, similar to a ratchet that one turns. When 5T also this beautiful noise is no longer present.
The Processing:
If you caught a usable copy, quite well, but only in my third copy of the screen was just installed! All three copies is equal to the projecting in the upper right corner display screen. Because apparently a cable is underneath, which prevents the display screen is flush. One sees in the dark there then the light shine through. When 5R neither was the wrong screen, yet you could see the cable or the light from the corner. I'm really disappointed that here as a "quality" is delivered. Sony I am not yet accustomed to does not fit the processing quality of the lens.
Operation:
Since I have nothing to complain about. I like the Sony really. You can configure a lot so that it fits on one. I also use similar fixed focal lengths my Pentax to an adapter and feel that the focus can be adjusted quickly and accurately by the "peaking" and the "magnifying glass". Even sending the images to a smartphone or wireless to my Macbook is really fun. The camera can also be completely remote controlled, so that the smartphone displays the live image.
The Pictures:
I can only speak positively about the 5T here. The quality is excellent and sharp even with the kit lens. Very nice colors and autofocus always hits. There are plenty of selectable image effects, some of which are very convincing. Only the JPG compression me going a little too far. A 16MP image is compressed to an average of 4MB, despite the setting "fine". Here I would still want a "very fine". The RAW images with the kit lens are greatly distorted in wide angle. Here it must be made first in postprocessing necessarily a lens correction. The tool "Darktable" is well suited for it.
Conclusion:
The 5T in my opinion is a savings option of 5R. Nevertheless, it is an excellent and especially lightweight camera that you like entraining. The NFC feature is just a gimmick, what you used initially only once, after which the software "PlayMemories" has the camera already in memory, so that one no longer needs the NFC feature. There are only exchanged the WLAN parameters via NFC. Unfortunately, Sony has not convinced me with the quality of workmanship and material selection. My third copy still remains with me.
