OK, anyone got an alternative??
Does Canon have anything equivalent to the AF 180/2.8 nikkor? I find that a very acceptable alternative to the Nikon 70-200 VR, lots cheaper (mine is an early 90's job I got for 200-odd) has comparable image quality (some might argue purer and sharper) and so much lighter that you can take it with you on the off-chance that you may need it. I mostly use the 17-55 and a 105 VR, but it's very useful to be able to pull out the 180 if something is just a bit too far for the 105 to reach. Between the two of them I've never felt any pressing need for the big pro zoom.OK, anyone got an alternative??
Depth of field depends on focus distance and focal length; a couple of examples :My findings on the sharpness of this lens after one day
DOF... is measured in mm at 2.8. I tried a hand held shot of the wifes face with focus on her eye. I loaded it in the PC and set it to actual pixels and the eye was blurred. HOWEVER, the eyelid was as sharp as a pin!

200mm F2.8, Focus Distance : 10 metres, DOF : 26cm
200mm F2.8, Focus Distance : 5 metres, DOF : 6cm
70mm F2.8, Focus Distance : 10 metres, DOF : 212cm
