Are AI conversions for K lenses are as simply as an aperture ring replcement? And if so, would the K-AI conversion kit (aperture ring) be the same as the AI ring?My limited experience swapping K and Ai aperture rings is that the Ai kit ring can (obviously) swap onto a K lens, and the K ring should go onto the Ai lens without issue. My experience: I have switched K to Ai, and Ai to K, on a 28/2.8 K/Ai lens a few times between the two copies of the lens.
Example: 20mm f/4 K conversion kit have the same aperture ring as the to 20mm f/4 AI. This was listed as the cheapest conversion option based on Roland's info http://www.photosynthesis.co.nz/nikon/aimod.html which suggests labour and parts (and shippping) were reasonable simple.
The background to this is I have a Nikkor 20mm f/4 AI but it's got some problems but have an option on a 20mm f/4 K that is in good condition - I wonder if i can simply swap the aperture rings (from AI onto the K) and have an AI'd K lens. Milling/filling the K ring is something I'd like to avoid since I have an AI aperture ring.
. And speak of insanely expensive, why I could buy a decently good SP, perhaps with a lens, for the price of one of those Trijicon widow makers. Goes to show: It pays to have certain "friends". (Please don't eat me!)ABout the only underwater photography I've done recently was on travels where film is not practical, and I don't anticipate using a Nikonos film camera in the foreseeable future. But earlier today I was at the photo repair and old stuff store, and they had a Nikonos II in worn but working condition, no lens, for $5.00, and an invisible hand plucked a bill out of my wallet and... well, you know. It's been there a while, and I just couldn't stand to see it languish.
If by chance someone for whom shipping from Eastern US is a practical matter would like to pay the small amount for a small flat-rate box, I'd be happy to send them the thing (I'll eat the 5 bucks if you can use the camera).
The camera in question has a foggy viewfinder, and it's definitely been around, but the shutter works fine, and it seems to be in good working order with no signs of leakage.
