I've finally bought some lamps to make a small photographic studio.
I bought this set on Amazon: LAMPS
Here is a pic of them in my very cluttered and small work area
And here is the picture taken of the lens. There's no postwork at all, not even to clean up the mark on the lens
I'm very pleased with the result. I use this set-up to primarily take pictures of my scale models.
Incidentally, I found fungus on this lens (even though it's kept in a flight case with lots of silica gel) so have ordered a set of lens spanner's on eBay to try and DIY clean it myself with some white spirit vinegar.
