I have recently become very interested in photography and I have been saving up to buy a very nice camera. I already have an old canon DOS from like 2001 with a lot of lenses and stands. so my question is what camera should I buy now. Should i go for something more compact like the sony nex5 that has a great shooting power in size. or should i upgrade my old canon DOS to a newer one. Btw i am going on a trip to greece later this year so whatever camera i buy i am also planning on bringing with me to take lots of pictures.
