Defeated.

The lens on Olivia's Nikon J2 has been cactus for quite some time and I got serious today about effecting a fix for it, the problem has been the aperture iris thingy shown in the middle here stays in the closed up position, rendering the lens quite useless.
After much work I finally gained access to it but the years do condemn and I consider it somewhat beyond my ability to fix.
Happily this prompted me to seek a replacement lens which to my surprise I found one at a not too outrageous price and grabbed, the new lens is a 10-30mm job which is a technically superior unit to this base model 11-27.5mm one. I say technically because I was struck by how good the images were from this inferior lens.
