if me ill go 80200. never tried sigma but two touch sharp quite awesome to me. sorry no photo for dat

I don't have the nikon 50 1.4, I thought it would be sharp at f/2.

In a wedding & another event, I used a D90 with Nikon AFD 80200 f/2.8 two touch version & not the 2 previous models of the push pull version. It is sharp and built like a tank.. and it weighs like a tank too... I believe it is more durable & could withstand more hard knocks than newer lenses with SWM motor and VR.

Speed wise, newer lenses like 70200 VR & VR2 and the Sigma 70200 HSM focuses & locks focus faster. I tried an older version of Sigma 70200 HSM and it focuses really fast, & the latest version with OS would be much better I guess. Suitable for events, weddings & fast action stuffs. BUT KEEP IN MIND that the Tamron 70200 comes with a slow motor (micromotor) and focuses really slow. The Nikon 80200 is faster imo.

The older 80200 is damn nice but it is slower (don't know how much slower it is) compared to lenses with SWM/HSM motor like the 70200s. For portraits, outdoors the 80200 performs fast enough.

- If you really need the best with VR - Nikon 70200VRii or Nikon 70200VRi

- Still want fast focus with lower budget - Sigma 70200 (there's 2 current models with & without OS (VR equivalent) and if you want sigma, make sure you check the focusing because some tend to back/front focus)

- Don't really shoot fast moving objects but want tank like build quality & durability - Nikon AFD 80200 (two touch version) -NIKON-

hahaha ... u just broke my heart bro cos i am going to change my 16-85 to a 17-55 ...
