Pros: Sharp from about f/5.6. Small and unconspicuous.

Cons: Flare, wavy distortion

Opinion: This lens is best used in the f/8-f/11 range; wider apertures are there essentially to ease focussing, it seems. Nevertheless, this lens performs rather well at close-ups (!). The wavy distortion can be nasty on architectural shots; fortunately, software such as Adobe LR provide a correction profile (AF and non-AF being optically identical). Beware of sunlight; if it cannot be avoided, the older 20/3.5 UD (non-AI) may be the better alternative. Every now and then, I mount this lens for street shots where people are not aware that they are in the frame: that lens looks like an ordinary fifty, but...

Pros: Fenomenal sharpness, construction, fluidity ring fire for video

Cons: one more light stop would not have spoiled, the cost of the used, difficult to find used

Opinion: I claim that I make 80% video and 20% photos, but I have taken this goal by reading enthusiastic opinions and I must say I can not contradict them. This 20mm is one of the reasons why I often buy vintage manual focus lenses. The sharpness and construction are its strong points. Even at 2.8 it gives a good result, but from 5.6 on it is a blade. In some rooms it could give a minimum of vingulation, quite normal for these focal points, but everything can be resolved in post.rn Unfortunately there have not been many around and who has it if he wants to pay it fairly expensive. It is also good thing that if one day I would give up my I would still have a lens that kept the price very well.

Pros: Optical sublime, like all masterpieces manual focus Nikon old school! Very compact, light but robust at the same time! Sharp enough and very pleasant blur of a grandangolo.Ottimo for daytime photos!

Cons: If you need an optics for photos at night or in any case in particular, to do photography at the Milky Way since his years and the few treatments to slow you notice any abbondati do in some situations, that very often difficult to remove in post. The solution? Just do not let the bright spots in the scene!

Opinion: I recommend it for those wishing to take photos of architecture, street or just landscaping, maybe I would point less for night shots but who choose these optical knows what he wants, the quality 'and there is all you see, logically you have to like yield have these optics and many times you have to take precautions, we say that you must be familiar with the optics before you can make the most!
