Re: 18-135 vs 18-270 performance

At which aperture you judge the lens?

I have a Sony DT 18-250, I have tried everything to have sharp pictures at the long end with max aperture (tripod, 2 sec. delay, ISS on and/or off) with no success, then I have discovered that closing the aperture by one or two steps the lens became sharp! At f.8 is almost perfect!
