BTW, I would consider the 105mmm Micro's to be noticeably sharper than the 105mm f2.5 at 4-5' at wide apertures, though you may want the slightly reduced sharpness of the f2.5 at that distance for portraits. (If very-close to medium distance performance and ease-of-use is more important to you, take the AF version if moderately-close to infinity work is more important, take the MF version if 6' to infinity is all you require, save money and take the 105mm f2.5).

The Nikkor 105mm f2.8 Micros (both MF and AF) come close, though each has a few compromises. Finding a lens that is great from 2x (with tubes, converter, or achromat added) to infinity at wide apertures is pretty difficult. (You might want to check out my 'SLE(MN)' again.). As you approach 1:2 using a tube, the CRC approaches the infinity setting, but the lens is still good stopped down. As for the 105mm MF Micro's CRC, if you use the lens at 1:1 on a tube, the CRC is nearly optimally set. I did not like the 105mm f4 Micro-Nikkors I have tried - the 105mm f2.8's seemed better to me throughout their ranges. The 105/4.0 AI or AIS Micro-Nikkor is probably the better and certainly the easier lens to use for serious close-up and macro photography.

Notice the free working distance of the 105/4.0 v. As for the change in focal length I estimated 92mm for the 105/2.8 Micro but the lenses has CRC and change in focal length seems complex. The 105/2.8 AIS Micro makes a good general purpose 105 and macro.

There are two manual focus 105mm Micro-Nikkors, an f/2.8 and an f/4.0.

Best image sharpness occurs at f/5.6-f/8 and the quality deteriorates very rapidly beyond f/16 (this decline is common to all Micro-Nikkors). The lens flares easily and the use of a long lens shade is recommended at all times. However, the CRC system isn't working optimal when the extension is added so Nikon advises the lens be stopped down more to retain flat-field correction. To go beyond 1:2, it's necessary to add the PN-11 extension ring. The focal length is a mere 88 mm at the near limit. Unexpectedly, peak performance occurs for distant objects and the image quality is slightly reduced when it is brought to its near limit at half life-size. This complex lens design features CRC correction to give it very good image quality over its entire focusing range from 1:2 to infinity.
