Hi my question is in good light outdoors on a monopod with an experienced user is there a sharpness diffeence??
Say on asunny day using Av f8-f11 and setting 200iso .As this would be a common senario I am wondering on the benefits of chasing a copy of the f2.8 Vr, maybee i could get by with the F4

at f8 there is pretty much no difference in IQ whatsoever.

I wish I could comment, but I have used neither lens...but Rooz has used both!

Without ever using a lens longer than 85mm, I would guess that the difference will be significant at f4.

Perhaps speak top member Jeff, he has used both lenses, and now has the 2.8 version.

I Have a non Vr f2.8 on offer but I am wondering about the F4,If BobG dindnt sell his I would have the VR by now--teach me to move toooo slow--jim

From my usage, sharpeness is the same, of course you get the extra stop, other than that, not much difference.

Thanks for the feedback --as expested sharpness = same
advantage xtra f stop and Vr for those low shutter speeds--jim

apart from the obvious advantages you pointed out, there are 2 other big differences in the 300/2.8.
1. focus speed. this is huge, and i mean a HUGE difference.
2. easier use of TC's. a 1.4 tc on a 300VR gives you a 420/4 lens without any noticeable diffence in IQ or focus speed.

once you stop the lens' down to around 7.1 though the IQ difference is barely perceptible. what i am noticing is that the 300VR has a slightly warmer tone.
