Will Nikon Drop the Aperture and Meter Coupling Levers Soon?

(1/4) > >>

David H. Hartman:
I expected E-Type lenses for sometime. I'm thinking the aperture coupling lever is one more feature that limits high frame rates hence the E-Type Nikkor. The aperture coupling lever is complicated. I'll bet the D6 lacks both. I'm thinking a Nikon Df2 or Df3 will one day be the only Nikon to fully support Nikon F lenses from 1959 to date.

Akira:
Dave, another major problem of the mechanical aperture coupling is the inability of controling aperture in live view mode and during the video shooting.  Canon has no problem with that in the first place.

Ilkka Nissilä:
Nikon are still introducing new G lenses, the only way to use those lenses is through the mechanical transfer of the aperture information from the body. E lenses seem to be introduced in specific cases where there is a significant advantage for doing so. Given the tens of millions of G lenses in circulation and their relatively recent designs, as well as Nikon's history of supporting older lenses on new cameras, I would not expect an E only camera body in the F mount in the foreseeable future.

Bjørn Rørslett:
Agree with Ilkka. Keeping a maximum of backwards compatibility has been a major concern for Nikon over a very long period. There is no doubt the Nikon engineers would love an all-"E" approach, but that is not going to happen for a [very] long time. The introduction of low-end "E" lenses will be the indication of a future with main emphasis on "E" cameras. As long as "E" is associated with high-end or specialist optics, this has negligible impact on Nikon's policy as long as the thrust is on cheap "G" lenses.

bjornthun:
The recently introduced f/1.8 G type primes are going to be around for years, and there is no way they won't be supported. For mechanical reasons (physically) long telephoto lenses and PC lenses are obvious candidates to be E type lenses.
