iPhone5, worth the upgrade?

I guess I'm a bit stupid to answer this since I love windowsphones, but hey I used to have iPhone3gs+iPodTouch and shifted to HTC HD7 and never actualy looked back. Now desperately waiting for Lumia920/AtivS/8X to reach here so I could choose from them. :)

Anyway back to topic and just want to share. Maybe if you're coming from iPhone4s then the answer for me is NO, as I don't see any interesting features of 5 compared to 4s unless you're dreaming of an iPhone with 4" screen or just a die-hard apple supporter.

My next lens: Tamron 24-70 F/2.8 VC USD

I guess me and very few people are only showing interest to this lens especially in PiPho (pinoyphotography.org). Maybe the price? for 3rd party? I don't know.

For me considering plus vibration compensation, moisture resistant, faster/silent focusing, improved IQ and much better build to my 28-75/2.8. For the price of $1200, this lens is still cheap as it gets compared to Nikon and Canon which has both no visual compensation.

Letting go my Nikon 85mm F1.8D...

I'm already giving my AF Nikkor 85mm F1.8D. Here are the full details posted at tipidpc.com:

I Recently realized that I "rarely" use this lens because of its very specialized purpose to a certain scenario only eg. more room space, better background to produce nice bokeh, and outdoor portraits.
