I found it great for all sorts of subjects. Here's just a few...
It was nice not having to worry about which lens to use, and the exposure system performed very well. I used mainly Ilford FP4, and when I'd run out of film (India is that sort of place !) I bought some Indian Kodak colour neg. film, and continued with that.
I like the XA2 as it's so quiet and unobtrusive. However, as streets in India can be rather noisy (understatement of the year) I often wasn't sure if the shutter had fired !
The Zuiko 35mm lens is really good performer, and I found I could enlarge the pictures alot.
