if im not wrong, whether FF or DX, Nikon seems to be doing away with aperture rings. the "G" lenses have become more common in recent offerings, even "pro" lens - 70-200mm.
Nikon never state reasons. but probably due to considerations like:
1. simplicity - less moving parts
2. weather-sealing - aperture ring creates "gaps" in the lens structure
3. compactness - with AF-S and VR and what not, maybe Nikon has decided to do away with the aperture ring:
Points 1. and 2. seem plausible but nAi, Ai, Ai-S and AF-D lenses have been around so long and the problem of mechanical failure and weather sealing haven't been major problems. Otherwise, there would have been many people complaining about them. Remember, nAi lenses were used in many wars, the most notable being the Vietnam conflict - a war fought in the hot, steamy and wet (sounds like a porn advert eh?) jungles of that country. If there were any issues with weather sealing, it would have come up by now and been resolved.
WRT to point 3.
If you have noticed, if anything, the new G lenses are even larger than the ones they replace. e.g. 105 VR
Also The 70-200VR may be slimmer but it is longer than the 80-200 AFS it replaces. And definately larger than the 80-200AFD.
I've said this b4, it is not because of technical issues that an aperture ring cannot be retained. Case in point - the 80-400 VR has an aperture ring. To include an AFS motor as well would be a non-issue as the ring structure of an the SWM can be made to fit the barrel.
Rather, it is more to do with marketing strategy. Like Canon, Nikon is forcing users to buy their new lenses by removing total backward compatibility. There was a very healthy market for their used lenses until this happened.
im not a fan of "G" lenses, i cant use these with my FM2, but for what it's worth Nikon seems to be catering to the lens market, ie. on-body aperture control. so there's pretty much nothing we can do.
Since this thread OT already, let me put in my 2 cents worth.
You are right - unless everyone boycotts their new lenses and demands they return to making lenses with aperture rings - ain't gonna happen unfortunately.
As for the FF vs. DX debate, both have their pros and cons? i don't see why "Nikon must/should give us FF". it will come when Nikon's decided that it should come. right now, i think what we want more (if im not wrong) is quality, not size of sensor.
read: better noise control at higher ISO, better RAW compression, faster processing throughput.:
Whether it is introduced will be determined by market forces.
given current technology, the above seems easier to achieve than FF. yes, many are not satisfied with DX, but who's to say FF won't give us a new truckload of problems? :dunno:
Perhaps a new FF dSLR might give problems, every new product has bugs to be ironed out. But I don't forsee major problems. Nikon has the mistakes that Kodak and Canon made with their FF implementations to thank for that.
