Quote: Are all 50mm's very similar to each other in terms of manual focusing?
Pretty much I reckon though I'd say the Nikkor has a better feel than, say, the Canon (I've got both). Don't forget that the AF system will still give you focus confirm/assistance. The f1.8 aperture does help the subject 'snap' into focus tolerably well even with the relatively small and dim finders of APS-C cameras though it still takes a bit of practice to focus accurately in manual with any degree of speed...
WHS ^^^^ but to add that all AF 50mm lenses are similar in terms of manual focussing - MF lenses tend to have a greater arc of travel from close to infinity, so are easier to focus accurately than AF ones. Makes aperture control a little awkward on a D40 though!
