I also now have a Nex 5 camera. Well as of last week really.
Its a great camera and the image quality is superb. I debated for many months about getting one and all i can say is im not dissapointed.
Im now actually selling the A700. This main reasons for getting the nex is that the A700 is just to big and bulky to carry around for a day out with the family. Another factor was the video.
Its a little strange at first getting used to the menu system when you been using the A700/900 one for 3 years and having no viewfinder is strange.
(and Yes, i have on a couple of occasions put it upto my eye
) The size of it is another weird feeling, when youve gotten used to the size and weight of the A900, but its great at the end of the day after a day out with the family as you hardly know its there.
I ended up getting the twin lens kit, though as yet have only tried the 16mm lens just to make sure its alright.
