"RE: Understanding Macro Lens Apertures (Micro-Nikkors)..."
Call me dumb, but I still don't understand this.I have the Sigma 150mm F/2.8. So you can only get f/2.8 at infinity and at 1:1 you get f/5.6. So this means at 1:1 you lose 2 stops of light? If so, then why is it not called a f/2.8-5.6 lens because it changes apertures like on a cheaper zoom lens?
