70-200 f4 issue (bird on a wire)?
Oct 10, 2012

Does this look right to you in terms of the sharpness I should expect from the mighty 70-200 f4 under ideal conditons (bright daylight, f5.6 sweet spot, stationary subject)? Admittedly at full reach 200mm but that's what this lens is designed for, right? ISO was bumped up to 320 to ensure no motion blur.

I snapped about 20-30 pics and they were all about the same i.e originals looked promising but disappointed when cropped. Was using One shot mode for this pic but I went out and repeated under AI Servo and got similar results.

Original pic (OOC). Looks promising...

Big crop (no other processing). Pretty disappointing.

Same crop (some major sharpening and NR in LR4). Slightly better.
