300mm Question

[usayit]

This isn't a fair comparison to see and conclude that the DO is heavier. .

First to point out... even with IS being heavier it is still $4100 premium for what??

Read my previous post again... weight is just one part of the issue...

If weight is a concern... 400mm f5.6L and you save $4100
If speed is a concern... 400mm f2.8L IS and it is just $1300 more
If Image quality is a concern... 400 f4 DO is NOT the best in the category. DO optics have not proven to be up to par with its regular optic brotheren. Either the other two will be better.

1 stop is 1 stop but at a premium of $4100????

Makes no sense.

You brought up the other DO lens... that is even a worse example. You pay $500 more and all you get is .2 lbs lighter weight and 1.7 inches shorter??? Again.. not to mention the crappy DO optics...


ah.. didn't mean to stray so far off topic...
