Quite a few people end up here to try to get answers to their “million-dolar” questions, such as: “Is my D50 motorized or not?”, “Can my D100 focus and meter with manual focus lenses?”, “Is my D3100 geo-tagging (GPS) capable?”, and so on. I have concocted a compatibility table that pretends to answer these questions all at once, and is available in both HTML and PDF format. I hope it helps :)
The Nikon F-Mount was launched with the Nikon F camera in 1959 and has remained virtually unchanged since, making it the only lens mount still in production over 5 decades after its introduction. The camera mount comes essentially in 3 flavors: F, AI-S and AF, with some minor adaptations for particular cameras, mostly the digital entry-level models, which feature 2 extra screws and the minimum aperture confirmation notch, discussed later on.
It's been already more than five years since I wrote this article (in Spanish) on autofocus and although in many areas the innovation of DSLR’s has slowed down some, autofocus systems are still making unimagined jumps. In this article we review the 51-point system, which was introduced in late 2007 in the Nikon D3, D300 and the evolved version of which is used in the D7100, D810 and D4S (Advanced Multi-CAM 3500).
If you want to quickly assert if your lenses are focusing properly, my friend Carsten recommends the “Newspaper Test”. This works very well, he says, because we are so used to letters that we can judge “readability” much better than a certain degree of blur. It is also the method of choice to test longer lenses at different distances, because for that both the ruler and the domino test are a bit tricky; it may be quite difficult to judge the results at a focusing distance of – say – ten meters. If you want to quick assert
Now that even the most modest Nikons feature 24 Mp. sensors, optical quality and lens performance are increasingly coming under pressure. It is no coincidence that many of the latest Nikon mid-range and top-of-the line cameras include a feature called “AF Fine Tuning” which allows users to adjust the auto focus of their sample of a particular lens to their particular camera.
