This was the night my Sigma had a close encounter with the rocks and stopped focusing properly, and my Lee 0.9 ND gained some battle scars, but the old lens still does a good job. I'm just pleased that when I'm shooting landscapes the speed of focus isn't usually an issue! lol
Anyway, I've also found a solution to my Mac and it's painfully slow wireless connection, use the ethernet! And now it's a pleasure again browsing again and I don't have to wait an age for a page to load, so I can get back to normal.
Thanks for looking and thanks for the support recently
