Originally posted by Clinton I just took a stroll through the Nikon gear on Amazon, just to get a picture of what their glass costs compared to Pentax glass. Obviously, our similar glass will be used glass, for the time being.
Nikon: 600/4? $10,000
Pentax: 600/4? ~$6500
Nikon: 400/2.8? $9000
Pentax 400/2.8? ~$3500
Nikon 250-600? Yeah doesn't exist.
Pentax 250-600? ~$8000
Nikon 300/2.8? $5900
Pentax 300/2.8? ~$3600
Nikon 200/4 micro? $1600
Pentax 200/4 macro? ~$4000 (ouch)
Nikon 85/1.4? $2000
Pentax 85/1.4? ~$1400
Nikon 70-200/2.8? $2400
Pentax 80-200/2.8? ~$1300
Comparing the 85/1.4 lenses, a more fair comparison might be to the screw driven 85/1.4D of the same vintage as opposed to the much newer 85/1.4G with the built in AF-S motor.
Nikon 85/1.4G $1700 new, $1400-1500 used
Nikon 85/1.4D $800-900 used
Pentax FA*85/1.4 $1200-1400 used
Comparing the 70-200/2.8 options, again I would argue that the 70-200/2.8 VRI is the closer comparison to the 80-200/2.8, and they are about the same price used. Then don't forget the VRI has a silent and fast built in motor and VR.
Nikon 70-200/2.8 VRII $2400 new, $1800-2000 used
Nikon 70-200/2.8 VR1 $1300-1500 used
Pentax FA*80-200/2.8 $1400-1600 used
