Introduction
As you could or could not know there have been a number of totally different variations of the Nikon AF 180mm 2.8 through the years. Most notable was the addition of the “D” function in 1994, permitting the lens to transmit distance info to the digicam for extra correct utilization of digicam flash. As this lens was first launched in 1986 among the samples method an age of 40 years. As with each product that previous, there are some issues to pay attention to once you want to purchase a used pattern. Certainly one of our readers, Q. Xu, did a side-by-side teardown of each variations, so we get to have a better have a look at the variations between these variations and what to be careful for.
In fact this text can also be of assist in case you are trying to carry out some type of repairs on this lens by yourself.

You’ll find the complete information right here. I’ll solely present some excerpts on this article.
Variations between non-D and D Variations
The plain exterior variations are that the nameplate is totally different and likewise barely larger on the D model and that the aperture ring options an extra third row of small grips. Much less apparent variations are the positioning of the lens hood on the main target ring and an extra ring containing the aperture lock lever on the non-D model.
There are additionally inner variations that will not be as apparent. The later D variations function the improved Tremendous-Built-in-Coating (SIC) whereas the non-D lenses and likewise the early D lenses function the Nikon-Built-in-Coating (NIC).
The D model has a flex cable (orange) connecting the space enconder on the main target ring to the digital contacts on the rear of the lens.
This can be a considerably extra complicated design in comparison with the non-D model, which solely encompasses a tiny circuit board (inexperienced) wrapped across the rear mild baffle.
Whereas all of the optical parts are the identical (apart from the coatings), this isn’t true for the mechanical components, so not all of them are simply exchangeable between the D and non-D variations.
What can also be notable: whereas this lens is taken into account strong and prime quality, there are not any steel components to be discovered right here. Every part is produced from polycarbonate.
Purchaser’s suggestions
One widespread situation is noisy focus operation (additionally throughout guide focus), often attributable to the rod connecting the screw on the bayonet to the inner gears. That is straightforward to identify because the lens will make some grinding noise throughout focus operation.
Including lubricant to the gears of this rod often helps to eliminate that noise.
One other, larger situation are hazy samples. This could be attributable to balsam separation of the cemented teams and likewise broken coatings. There are additionally lenses circulating with a excessive quantity of mud inside, as this lens doesn’t function any climate sealing.
After I checked, the D variations have been about 100 to 150 bucks dearer than the non-D variations. Is it value it? If you wish to use this lens on Nikon SLRs together with on digicam flashes quite a bit: perhaps. However I don’t assume lots of people will truly try this. The one different motive could be the improved coatings, however with out having completed an intensive comparability, I’m not certain in the event that they make sufficient of a distinction to pay about 50% extra. And you could ensure that to get one of many later variations for that anyway.
A full assessment of this lens can even be printed sooner or later.
