Thanks ppl!
Midway down the line, I narrowed down my choice to NEX and A55, and chose A55! With the considerations below:
1) no need to buy adaptor to use my A-mount lens
2) no need to keep 2 more SEL lens for nex
3) small and also quite friendly for my wife to use
4) love the 10fps and more silent shutter sound
5) Love the AF in video mode, simple to use -fun factor
6) In built GPS tagging! nice geo tags when uploading to sites supporting geo taggings.
7) Plenty of features!
8) Focussing is very very accurate compared to A550! usually the assist AF will caught other objects beside in wide angle view, but A55 will get it right!
9) 100% TRU VIEW! and TRUE COLORS! colors is superb, really bring out the potential of my lens or at least felt that way =)
Well , after owning A55, like to share a few negatives too:
1) really small grip for my big hands- still acceptable to hold though
2) battery life is better than A33, but not as good as A550
3) Flash photography at dark/low light is difficult, as cannot see via EVF or liveview, miss the optical VF in this case.
4) panaroma sweep needs practice to shift sideways and not around the center, need to get used to
5) tilting screen not suitable for large tripod base mount
6) Shooting movie and zooming tends to be very susceptible to shake, will need monopod or tripod for stabilization, if it is A580 I think even moving the focus ring will shake all the way!
Of cos there is ZACUTO if there is depth in the pocket, not my option at all. Any other ways?
Enjoy shooting! Everyone! Cheers!
I will be bring this baby to my honeymoon!
