Nikon 200-400mm f/4G IF-ED VR AF-S

Review Date: Nov 22, 2009 Recommend? no | Price paid: $5,500.00 | Rating: 8 

Pros: Zoom, good Details
VR without good performance, too long, should beginn at 100 mm, AF not really fast, not really sharp at f:4,0 not very brillant before f: 8 Price much to high,

Three years with it, enough!
Olympus 2,8/90-250 mm is far better, even with 1,4x and 2x Converters.
Nikon has no really good Zoom behind 24-70 mm!
Nikon is great with the 4,0/500 mm and 4,0/600 mm,
but this Zoom is not good enough, I' ve worked with three different, none comes close to a fast prime!

Sigma 150-500mm f/5-6.3 AF APO DG OS

Review Date: Aug 26, 2008 Recommend? no | Price paid: Not Indicated | Rating: 6 

Pros: good built, very good OS
slowly AF, not precise, nor on Nikon, nor on Canon; OS is strange noise; to heavy; dont like the surface

I tested the 150-500 against Sigma OS 120-400 and Canon 100-400 IS.
I choose the Sigma OS 120-400. It is far better then the others.
But Canon has no AF trobles and f his focus is much faster.
Wondering why these are no EX-Lenses.
The 150-500 ist good until 300 mm. But therefore its to heavy and large.
