I've been partaking in the world of photography for 35years and when I started out, standard lenses were all f1.8 (or thereabouts) then and all but my last two camera bodies would have come with such as standard.
I had the very capable and tiny 'pancake' f1.8 m/f Nikkor (that I can still use on my full-frame D700) but one day I just wanted handle and feel the classic 50mm Nikkor f1.4. Its use in animation and technical copying were legendary. I saw a documentary on how an older version was used on a Nikon F3 to take the stop-and-go shots on Stephen Spielberg's Raiders of the Lost Ark, before CGI.
I was going to be able to buy into an elite club of photo excellence, for a couple of hundred; a new 'D' A/F one at that.
You always know where you are with this lens. Aside of very few specialist lenses, it is the fastest ever made and the viewfinder image at night is as bright as your own vision. At ANY aperture, including wide open, you get an image bristling with detail that other lenses have to be stopped down to even approach.
With so many 'premium' standard zooms lenses these days weighing as much as the camera, this diminutive but still perfectly handling 50mm feels so refreshingly different. One almost feels liberated. People notice and often remark.
It also makes an exemplary lens for copying one's work, such as mounted prints, due to absolutely zero barrel/pincushion distortion. I've done that to upload them onto my website and for a digital record. Use at least f4 to cover depth of field of the mount. Between f4 and f6.3 the lens is also performing at its best. Add extension tubes and you get an economical but optically uncompromised macro lens. Low cost independent ones (Kenko being my choice and which I also review) are usually fine and allow full AE and often AF, too.
A possible minus point is that there is no f22 aperture. The now old type of A/F always worked fine for me - though I actually enjoy the almost tactile experience of focussing myself - but is, as you'd expect, a little noisier and slower than Nikon's latest Silent Wave Motor mechanisms.
In conclusion, this is recommended to those who feel their zoom lenses are making them lazy - and want to get back to basics and go on a kind of photographic 'retreat'. You'll respect photography as an art-form and look harder for - and at - your subjects and make your hobby less of a half-hearted chore.
