LoCA is the least of my concern, in fact LoCA is almost certain for massive apertured lenses. The bigger the aperture, the thinner the DoF and hence more abrupt transition between focal plane and blur regions. This is why LoCA is greatly reduced when you stop down.

Unless of course it was made with APO glass, in this case it's not.

I would be more worried about flare though, even with SSC coating I'm getting quite nasty flare when shooting with light source in the frame. Time to look for a hood as well.

Congrats Leon.

I have not noticed flare being a big issue with this lens, but I've always used it with a hood, because I bought one for it before I had even completed the conversion.

This is the one I got. http://cgi.ebay.ca/New-Metal-72mm-Screw-In-Lens-Hood-For-Nikon-HN-20-HN20_W0QQitemZ200358167013

Works perfectly, as it is for an 85mm lens and is 72mm thread. Knowing that metal is protecting the front element is reassuring, too. (I purchased it from that e-bayer, BTW).

Paul,

Thanks for the guide and the link to the hood. I've been meaning to try my hand at converting my 85/1.2 SSC as well.

Thanks a lot Paul. I've just placed an order for the hood with that eebayer, probably will receive it next week.
