Today I tried to take some photos with my 70-200mm f4L lens mated with my Kenko 2x teleconverter (sure, it loses autofocus) the result is soft and really not as sharp as I would have right.
Do you guys think it is normal, or was it my techniques that was wrong. All shots are handheld by the way.
Shutter speed: 1/350
Shutter speed: 1/250
For the noise... I believe it might be because I have set the ISO too high... but that is the only why I can prevent underexposed shots as it is not that bright and I cannot set my aperture any higher than f8 (f5.6 would be nice).
Hope for your help in this.
