[Filter Test] 340AF15 UV-Pass

While I was outdoors broiling the D600 and some filters in this intense summer heat, I also grabbed a shot with my tiny little 340AF15 bought off the internet.

 

Had to handhold it to the UV-Nikkor, but didn't do too well at that.

You can see the Light Leak in the lower left quadrant.

 

I think the filter is deteriorating a bit. One side seems to be becoming filmy. It wouldn't clean up. Or perhaps this filter is layered and the humidity got to it out there in Swamplandia. I just don't know. It's not a good shot.

 

However, the photograph, while obviously deficient, does at least serve to show there is UV-signature capturable 25nm below where our filters normally peak. And, it doesn't look all that much different from what we normally shoot with a Baader U.

 

D600-broadband + 105/4.5 UV-Nikkor + 340AF15 + Sunshine

f/11 for 6" @ ISO 400.

This needed a long exposure time !! Today the same shot with the Baader U need only 1 second. (And that is actually a little big long, but I had some other variables at play today - location, clouds and so forth.)
