<p>Great list Stefan! Thank you for grouping here all the info! This helps me very much.</p>

<p><strong>Checking AI aperture nonlinearity</strong>, from a Sep. 2004 post by 'Ro Ro' in <a href="009KFX">http://www.photo.net/nikon-camera-forum/009KFX</a> :<br>

<em>"Another thing: I had to adjust the aperture lever inside the lens to get correct apertures. This is easy to check: Set the camera to a known aperture and then press the DOF button and hold it. When you then rotate the aperture ring from 22 to open aperture the blades should start moving when the aperture values match."</em></p>

<p>I chipped my 85/1.4 AIS: <a href="00a463">http://www.photo.net/nikon-camera-forum/00a463</a> .<br>

Clearances are a bit tight, but it's doable.<br>

I also started reshaping a chip for the 50/1.2, but I don't think it can be done without modifying the rear element mount. Does anybody know whether the rear element can be rotated, to gain some clearance at the chip location? </p>

<p>Has anybody made an EV/aperture comparison between before and after chipping an AI (converted).<br>

I've noticed that the 135/3.5 AI I've chipped needs a EV+1.5 correction compared to the lens before it was chipped (used as a "Non CPU lens" on my D700). <br />Both using the aperture ring on the lens to set the aperture value, NOT the dialcontrol on the camera (I allmost allways work in A mode).<br>

And if so, did you find a permanent solution for this EV deviation? Meaning without a manual correction on the camera, which I usually forget ;-)</p>

I will only note that I have had a "misplaced" glue-on chip actually blow out the circuits in a camera. It completely discharged the battery into the camera.

 

Inspector Kemp: A riot is an ugly thing. And once you get one started, there is little chance of stopping it, short of bloodshed. I think, before we go around killing people, we had better make damned sure of our evidence.

 

I decided that the need for 'linking' up was outweighed by the risk for me, anyhow.

You can add a 400mm f/5.6 IF-ED lens to that list. It requires some machining - or adept use of a file. See pic below.

 

WRT incorrect exposure after chipping: I suspect this is pretty common with pre Ai-S lenses due the non-linearity of the aperture movement. Also the aperture lever on AI or AI converted lenses looks considerably thicker than on Ai-S lenses, leading to an offset in the angle that the actuator in the camera has to move through for a given aperture. The lack of aperture linearity in AI/Pre-AI lenses is clearly noted in the Dandelion chip instructions.

 

Also I would never use anything but a good quality epoxy cement (specifically "Araldite") to fix a Dandelion chip to a lens.

Yes, but user reg_eggen stated that he was using the aperture ring. I suspect he read and understood the warning about AI non-linearity. What then explains the exposure discrepancy? Not a rhetorical question; this is something that has mystified me since I read that warning myself. I wonder if the camera, "knowing" that the lens is a P (and thus also AI-S) lens, therefore does not fully depress the aperture control lever during an exposure, but only moves it to where it should be if the lens were AI-S.

 

BTW, great job on the installation in your photo! I've only taken a Dremel to one light baffle, and the result was sadly quite messy:

It looks like this also happened to the photo.net time machine, as we are all replying to a thread from 2013 like it was yesterday.

Ah! I usually look for the date stamp, but not this time:(

I fear your mistake was to think a power tool would make a neater and more 'professional' looking job than hand tools.

 

A set of needle files and a junior hacksaw are much more controllable. The 'off switch' is instant and the tool doesn't run away and cut randomly on its own!

 

WRT non Ai-S lenses exposing incorrectly - a puzzle indeed. It could have something to do with the total non-linearity between the light coming through the viewing screen and the lens aperture. Opening any lens wider than f/1.8 makes absolutely no (zilch, zero, nada) difference to the screen brightness. And since the metering system is placed in the prism above the focussing screen..... well, personally I think there must be a telepathic link between Nikon's lenses and their metering system.

Lack of bandwidth?

Lack of bandwidth?

Unless that refers to elastic-band width, I can't see how that would apply.

elastic-band width

More 2 baked bean tins and a piece of string....;)

 

However, surely telepathy has a bandwidth like WiFi and Bluetooth etc??...:cool:
