Hello, I know there have been a few words of caution on possible sensor damage when flying (gamma radiation causing sensors to fail, thus RED LINE issues) but was wondering if anyone has experienced this first hand? And if so what measures can be followed to protect from this potential damage? E.g. would a lead-lined film protection bag be useful for the camera body? Thanks, Mike

Monday was a great day in England, cold, very bright with a North Easterly wind. Wanting to cram as many pleasures into one day I decided to take my M9 with my Noctilux f/1 (although I still think of it as Steve Huff's Noctilux) in the Chipmunk for a flight. http://ianspector.smugmug.com/Airplanes/De-Havilland-Chipmunk/Flying/20100308ics-M91587/805716412_MkBZg-L.jpg Shooting at 1000ft from Buckinghamshire to Dorset with the roof open I very soon realised that I was going to move the Noct off its normal f/1 setting. To my horror Even with the ISO at 160 some of my shots required f/8 at 1/4000. Whilst over Reading I could maintain f/4 and the shots could not have been sharper; at 100% I can see people walking in the car park. http://ianspector.smugmug.com/Airplanes/De-Havilland-Chipmunk/Flying/20100308ics-M91573/805704174_G6FAf-L.jpg However as I headed further south and onto f/8 my images were very soft; even after sharpening as can be seen here http://ianspector.smugmug.com/Airplanes/De-Havilland-Chipmunk/Flying/20100308ics-M91574/805707613_m8nnx-L.jpg I can only assume that given the smaller lenses diffraction is the culprit here. What are the accepted Leica lens limits before diffraction, and is it the same for all leica lenses? I guess an ND filter is in my future. Many thanks for your help., Ian
