I wont be letting anyone near the 1n and the 85L as they work beautifully! I am just so annoyed that I lost SIX MONTHS of shooting portraits with anything longer than a 50 due to this issue. I keep some kit in Kabul and exchanged lenses (taking time to get here from the US), exchanged again, exchanged bodies (from home) and lost a lot of time. I've been shooting a long-term project in Afghanistan. See 'Russians and Royals' www.thomasstanworth.com Almost finished now. I have a fair few more portraits printed and waiting for me in the UK.
