both the same size. 5T is older model, and 10 fps, I tried it in Best Buy, it's amazing fast, like a machine gun. 25000 iso but only 16.1 mp. A5000 is newer model. only have 16000 iso and 4fps. I bought A5000 because 20.1 mp and newer version and has flash. If you shoot sport a lot, then 5t is better. This is the image of A5000 https://www.flickr.com/photos/2009seasons/14501884263/.
Hi. I don't own this, but do have the A3000, NEX 7 and Rx100 each of these has a sweep panorama mode. The specs of the A5000 say that it has a sweep panorama mode, so I assume it does. By the way, the better panoramas are done with photo stitch software.
The Sony Alpha a5000 is built-in with 3 focus mode: Continuous-servo AF (C), Manual Focus (M), Single-servo AF (S). And, its Contrast Detection have the 25 autofocus points. To avoid blurry image, you can use the Manual Focus.
