Hi Peter, Thanks for your message, and sorry I'm just seeing it now, and I hope I'm responding to it correctly (still learning the wiki ropes). I've got a fairly late model D90 so I'd always just assumed I had the latest firmware. I don't see anything in the menu for lens correction, but I'll dig into this, since the pincushioning been a long-standing annoyance. A nice prime macro lens is on the short-list.
I'm about to upload another few photos, but after this, I'll try to upgrade if possible.
thanks!
Paul
update - I was actually quite a few revs behind (1.002 to 1.009). The update did seem to help somewhat; still not perfect, but better.
thanks again!
