I need some advice from experienced nikkor users
I'm on the edge to make some lense purchase. And I'm not sure if it should be the "AI" or "AIS" versions do to the focus precision.
And if maybe a follow focus makes my concerns irrelevant...
Zeiss is not in my budget. And I'm only interested in Manual Metal. I'm on a CANON 60D. Soon on the new 6D when its out.
As mentioned my issue is the "focus through". From what I learned, and the lenses I own, the AI version has a larger focus through rotation than AIS (except the macros).
General degree differences:
AI = 140-180 degree max (depending on the lense model)
AIS = 90 degree max
This made the AI lenses immediately superior to me from an operating standpoint. But I have to point out that I focus just with the lense up until now. So I don't own any focus-pull system.
1. Newer lenses over AI precision or not?
AI lenses are 30Yrs+ old but give better precision. AIS I can get as newer builds and some have improved coating.
2. Focus pull, does it solve my concerns...?
A focus-pull improves depending on the mechanic a bit to allot? Right? My common sense tells me "yes".
But I don't own a follow-focus so I don't know for sure.
For the guys that own nikkors AI and AIS with a follow-focus... do you feel any disadvantage with tha AIS in terms of precession?
thx for any help, it is much appreciated!
ps.: I want to purchase my lenses soon, so you might notice this post also in other forums... I just want to reach as much users as fast as possible... my apologies in advanced if that is bothering some users!
pps.: I own at the moment:
28mm f/2 AI (focus through rotation: 160 degrees)
35mm f/1.4 AIS (focus through rotation: 90 degrees)
And I have to say getting something in focus with the 35mm is a pain unless you close the aperture allot...
