For your references, below were the pricing/promotion during the recent comex.
Olympus, either the PEN or the OMD series - as per mentioned in earlier posts.
Sony mirrorless also OK.
Nikon the D5500 seem nice - small but not as small as Olympus or Sony mirrorless.
Canon - the cheaper DSLR should be OK - although same as Nikon, not smaller than mirrorless.
Don't get Canon or Nikon mirrorless. Instead get either Olympus or Sony mirrorless.
