A Question About 'Default' Aperture...

My old Nikkor 50/1.8D was sharper than my 50/1.4G, but I still prefer the 1.4G because of its better bokeh.
I loved the 50 1.4G's bokeh and especially the color. To me it has the same warm color that the 85 1.4G has. I shot the 50 1.4G vs. the 24-70 2.8 (non-VR) on the same targets and the color difference really jumped out at me. Skin tones and greens/yellows especially seemed more pleasing to me on the 50 1.4g.

I agree about the 105 DC bokeh. I also really like what it does with background "bokeh balls" highlight areas. The 105 DC has little diffuse round balls whereas most all the other ones (excluding 135 DC probably) have a cat's eye bokeh in some circumstances. I understand that's due to mechanical vignetting but I don't know much about the "why" they do that.

Here are some random shots (not best shots, just ones I have at hand) that show either sharpness or bokeh or both of these lenses just for fun. I think these are all SOOC except for cropping. I know the 105 DC one I adjusted the color temp and exposure some. Click "original size" on the large size ones to see detail.

105 f/2 DC - small size, "abstract" bokeh. Creative bokeh potential of this lens is way up there!

85 1.4G large size - creamy bokeh and a very sharp lens. I found copy variability with this lens though as my 1st copy wasn't as sharp as it should have been.

Zeiss 50 f/2 makro large size - these are more sharpness picks than bokeh pics. These are from my first test shots with the lens.

Zeiss 100 f/2 makro large size. Bokeh not as creamy as 85 1.4G but it still gives quite a 3-d effect in most all shots with wider apertures. Microcontrast and sharpness are nice with this lens. These are from my first test shots with the lens.

"G" lenses are lenses built without a mechanically "Automatic Metering System" contrary to Ai(s) lenses.
This sentence is not correct. 'G' means no aperture control ring, nothing else.
No - but let it be. It's another discussion. Ken Rockwell means, that "G" stands for "Crippled" :-)
Just when you thought you saw the end of this discussion... back from the dead

From the Nikon site:

G-type NIKKOR lens:

G-type NIKKOR lenses have no aperture control ring and are intended for use on Nikon D-SLRs that allow the lens aperture to be adjusted via the camera's command dial. In addition, like D-type NIKKORS, G-type optics relay subject-to-camera distance information to Nikon digital SLRs. The information is used to help determine ambient and flash exposure. A G-type lens will have the abbreviation G labeled on the lens barrel.

That also applies to non digital SLRs. The oldest SLR that G-lens is fully compatible with, was introduced 13 years before the first G-lens, and supported neither AF-S or VR.

Yes - but I said "no" to your "nothing else".

There are more differences, than the missing aperture control ring. It misses the entire "aperture indexing system" from the Ai(s) lenses - and instead, the "G" lenses reports as well the max aperture (as does the cpu-Ais) as the min aperture and the physical distance between the two.

""G" lenses are lenses built without a mechanically "Automatic Metering System" contrary to Ai(s) lenses."

This is correct - they are built to be used with an electronically metering (aperture) indexing system" - but still a mechanically aperture activating system.

Ye a slippery sucker that's fer sher.

It's no use trotting out differences that various sets of lenses have from each other. The one and only difference between every G lens and every non G lens is the lack of aperture ring on the G lens.

Yes a G lens is also a D lens Yes a G lens is also a non-AIS lens. but that's simply not germane to what distinguishes a G from a non-G.

Which is the lack of aperture ring. Nothing else.

No - it's not.

It's very germane in my opinion, that a "G"-lens is able to have more than eight full stops of aperture from max aperture.. Ai(s) lenses are not.

Neither in my opinion, is it without meaning, that the "G" lens needs some electronic in the lens (the cpu) to work at all, the Ais lenses do not need it - though some still have it.
Which is the lack of aperture ring. Nothing else.
Not true. - The "nothing else".

Actually - the differences between the system of the "G" and "Ai(s)" lenses are just as remarkable, as the differences between the "G" lenses and the new "E"-type lenses - in my opinion.
