You should see this:http://www.The-Digital-Picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=104&Camera=452&Sample=0&am p;FLI=3&API=3&LensComp=456&CameraComp= 452&SampleComp=0&FLIComp=5&APIComp=3


At f8 you could see a difference in sharpness, not even to speak of color and contrast, chromatic aberrations etc etc. The 70-200 is much more valuable. IfMaloyrajucould live with shooting without IS. The 70-200 will certainly make him very happy! Much more then his 55-250.

Thus I strongly disagree with you on this one.

That's for sure. The 70-200 is very usable at f4, it really kicks ass.


My idea remains: if he could live without IS, he would definitely be very happy with all aspects of the 70-200 f4. One downside of the 70-200 is the white/grey color, which makes you less stealthy, that's the only downside I can think of. And it's a downside which is very personal and very easy to solve so....
