<p>Hi everybody,</p>
<p>I am looking for user experience with the Micro-Nikkor 40mm DX lens. I'm thinking about adding this lens, after reading some positive reviews. I would use this with a D300, primarily for shooting portraits of children/newborns. This would be a specialty lens, primarily for that purpose, as I have a number of lenses near to that focal length:</p>
<p>Sigma 30mm f/1.4 (original version) - love this lens, but it doesn't allow me to get very close to the subject</p>
<p>Tamron 17-50mm f/2.8 (focus motor, non-VC) - MFD is shorter than the Sigma, but my impression is the lens is not at its best up close</p>
<p>Nikkor 55mm f/3.5 - love this lens, absolutely no complaints about sharpness. OOF rendering is pleasant too. </p>
<p>The 40mm offers me AF (nice to have the option), slightly larger aperture. I believe it may also work a little more smoothly with my D300. In my experience, the 55mm needs more post processing to get the right color and white balance. </p>
<p>I understand the 40mm has limitations with working distance @ 1:1, but this is not of great concern to me because I would normally be shooting at lower magnification. </p>
<p>Can anyone comment on strengths and weaknesses of the 40mm for shooting people? I expect some people prefer longer focal length for portrait, but I like being about to get close to the subject (especially with kids). </p>
