I was wondering what thoughts you have on the 300mm f/4 PF in comparison to the 300mm f/2.8 VRII.
Obviously the cost is much lower for the f/4 version, but the thing that interests me the most is overall sharpness given everything else equal. Does the PF version stack up to the f/2.8?
I know sharpness is a large encompassing term and there are many variables (i.e. hand holding skills, subject movement, settings etc.) but do you think that the f/2.8 is priced at its amount due to the fact that it is a faster lens, has better IQ, better build etc? And if so, how would you compare the 2 side by side for IQ?
The only pro lenses I have ever tested side by side were the 70-200mm VR I vs. the 300mm f/2.8 non VR and even though the 70-200 was superb, I felt the 300mm overall was just a step up. Was wondering if the same incremental performance might be similar with the 300mm PF VR vs. the 300mm f/2.8 VR.
Thanks so much for your opinions! They are very helpful :-)
