Many a telescope owner, after gazing at the sky for a while, wants more; wants to share what she or he is seeing. There are several ways to achieve this. The most obvious is shooting through the telescope eyepiece with a small camera or cell phone.…

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).
With the D700 now being fazed-out, semi-pros and advanced amateurs are left with two full-frame cameras to choose from in Nikon’s mid-range price bracket, the D800E and D800 costing $ 3.300 and $ 3.000 respectively, while the D600 will set you back $ 2.100, a premium of $ 400 over the aging D300S APS-C camera. Even in the absence of independent tests of the D600, it is interesting to compare it against the D800, to figure out how much more camera $ 900 buys us, and ask ourselves if it is worth spending the roughly 50% extra.
I am not going to nag about how my search traffic has dropped off to virtually nothing. I'm sure I deserve it. One can hardly pretend to know better than a couple of hundreds of Google engineers, right?
Again, as predicted by Nikon Rumors, today Nikon launched its new entry level D3100 DSLR with almost exactly the same core specs as rumored.The surprise for me, however, is that the D3100 includes GPS support, a novelty in entry level DSLR's and a feature which is - coincidentally - supported in the new Nikon View NX2 software with excellent Google Maps integration.
Can I use manual focus lenses on my Nikon DSLR? Yes, you can! Virtually all Nikkor lenses produced since the introduction of AI in 1977 can be mounted and used on virtually all Nikon cameras produced since 1977.
