Ah, I see now that it's the F/3.5-4.5 version. In which case the price seems very much on the high side. Here's a review: https://richardhaw.com/2020/07/04/repair-zoom-nikkor-35-70mm-f-3-3-4-5-ai-s/

Well, the 28mm is already AI, so why bother converting it to AI-S? I'm not sure which 35-70 that is, it doesn't look like one of the superior constant aperture F/3.5 versions.

Thanks for this Marc. Actually I did crop out the bud near the edge, also cropped out some of the vignette, if you look at the first picture in the thread. The second picture was the original uncropped version. I like to include buds in flower shots, even dead heads, as they help to tell a story. The lens is a Rokkor-TC 135mm F/4, which has a multi blade near circular aperture. Here's a picture, showing it with the Minolta MD to Minolta AF adaptor. You may recall that when Minolta introduced their AF system, they used a completely different lens mount - much to the disgust of owners of MD mount lenses. An adaptor was available but it had to include a glass element to maintain infinity focus, to the detriment of image quality. My adaptor is third party rather than Minolta's own. Thanks again ... the lens:

Can you explain in what circumstances the error appears? In what mode, with or without a lens, when putting film in etc?

Great write up on an interesting camera, I see the EL series as something of a transitional type between the mechanical Nikkormats and the FE. Wasn't the last EL version badged as Nikon rather than Nikkormat / Nikomat? And it seems to have been an early example of the trend towards all-black bodies as standard.
