The 105 DC for the most part introduces spherical aberration when the DC control is rotated off it's null position, which in a properly calibrated lens would be zero. Additionally as spehrical aberation is added, there is a shift in the depth of field so that the subject focused on will shift position in the zone of focus relative to where they were positioned previously. Of course the more you stop down from wide open, the less SA is evident (and the less the effects of DC is noticeable) until the DC control has little effect if lens is stopped down enough. This explanation is of course an over-simplification of course.Dave and Inner,
Good to know about the 105DC and sharpness. I had sort of noticed that just playing around with it and decided to investigate further -- at least assuming that 2 stops to the left is minus 2 -???. However, I have it currently set to f2.8 to the right -- what I assume is plus 1 -- and really like that as my standard look for most things I am shooting with it. One thing is certain, the effect changes with focus distance too, especially at closer distances. Note number 2 is the lens back-focused on my body and needed a -7 offset to zero it on my body.
I'll send you my 35 bud if you want to give it a run. Heck may never get it back. LolThat's a damn good observation :ROTFL:
In truth, I did love the 28 Cron, and I loved the 50 pre-Lux. But the 50 pre was always just a tad long for me. Given I have the 105DC, I will prolly end up with the 35/1.4 as my wider look lens -- I used the 28 Cron a lot more than the 50 Lux on the M. I really don't think the 35/2 will deliver the look I want, but if I could find one to try it is certainly worth looking at -- the 20 D renders nicer than I expected.
You won't LOLOL! I may take you up on that, but I really need to wait a month before even trying it -- my CC needs some serious rest to cool off :ROTFL:I'll send you my 35 bud if you want to give it a run. Heck may never get it back. Lol
Hi Uwe,I own the 70-200mm VR I zoom. Can anybody comment on the improved VR and optical quality of the VR II version compared yo this lens?
Hi Monza,On the 105DC what exactly is considered - and +?
I'm assuming rotation towards the F is - and towards R is +?
Dave do you have any links about Nikon shipping these with best sharpness at other than null? Thank you
Thanks Graham for mentioning the vignetting differeces between the two versions...it's quite significanty. My comments were primarily reflecting using these two lenses on full frame.Shooting full frame with the 70-200 VR II is SIGNIFICANTLY sharper in the corners and also vignettes less too. The original 70-200 VR is a great lens on a cropped sensor camera but you'll very quickly notice the softness at the edges of this lens. Otherwise, everything else that Dave mentions applies.
You're most welcome. Bet in less than one generation from now, the meaning of "shot a roll" will probably take on a whole new meaning...LOLThanks Dave. I just obtained one of these lenses, and have shot only one roll so far, should have first results in a day or two...all shot at f/2, -1. Yes, I know; a roll, how quaint, right?
Figuring out this lens works will be a good use for digital...heh he

I had a 70-200VRI when I used the d2h and d2x and never was totally happy. I found it somewhat flat wide open, finally sold it and then used a 180/2.8 and a 200/2.0 instead.I own the 70-200mm VR I zoom. Can anybody comment on the improved VR and optical quality of the VR II version compared yo this lens?
Yes, that's the plan...and hence my comment about a good use for digital.it would be a lot easier if you could experiement with this lens first on a full frame DSLR and at least develop a foundation for what effects you obtain by the altering the various settings and their combinations that this lens offers.
