In Topic: Photo Editing Monitors

22 November 2018 - 06:22 AM

Thanks for the input Chris.

 

The NEC is one of the monitors on my short list. Looks as good as the Eizo, but less money. Still not cheap, and not 4K. Not sure if the 4k piece is important?

 

BenQ comes looking good on paper with it's higher end models, but I do have some concerns about build quality and sample consistency.

 

I also do medical imaging to pay for all this, and need the monitors to be DICOM compliant, which the NEC is. It might be my go to:)

Hello Fred

 

I have no additional information on the first generation lens.

 

However, looking at photographs the knobs look the same, although both are silver.

 

I have a Nikonos 15mm ver2 which I have as a parts donor.

 

Send me a PM and I will donate the knobs, control shafts and screws for your project. You could then drill out the seized ones and hope for the best! I don't have o rings, but there is a fellow on Ebay in France who sells them.

I have been using Lanocote on threaded metal fasteners.

 

It is basically a waxy material made from lanolin and seems to work like a charm preventing galvanic corrosion.

 

You can buy it from boatyards for marine hardware and Backscatter stocks it.

I used Seavison in San Diego.

 

They did a great job; distance correction upper, plain glass lower.

 

Find a mask with tall lenses (e.g. Scubapro Spectra) to give more real estate.

 

I also had them bevel the lower edge of the upper corrective part, so looking downwards I am looking along the bevel, rather than across a flat, distorted transition. It gives the impression of no correction and makes more of the surface useful for vision.
