Fred, do you ever change lenses on location? If so, how?
And please dont tell me you use a zoom lens. For someone that is so hell bent on IQ and explaining why the Nikon sensor out performs any MF sensor, if I found out you used a zoom instead of primes, I think I would vomit.
Actually my lenses pretty much live on their camera for most of the time.
I avoid changing them on a windy beach. It's a real pain to have to stop shooting due to sensor dust.
With the relatively low price of DSLR's it's not a problem to have more than one... stick one on each lens needed for the shoot.
I think that in 10 years I've cleaned the sensor on my trusty old Canon 1Ds maybe 4 times.
Anyway I keep a bag of swiffers sheets (the ones with no fragrance... the fragrance is a wee bit oily).
Camera gets wiped off before switching lenses or going back in the bag at the end of shooting.
Those swiffer sheets swallow dust like nothing else and are dirt cheap.... they also get "recycled" to clean the floor.
Here's a swiffer pulled from the side pocket of my camera bag after a couple of camera wipe downs from working at a windy beach
with a stream running over it. The cameras actually did't really look that dusty
I highly recommend swiffer sheets... they just eat dust, lint... you name it.
IF you rub the swiffer against itself before wiping down it becomes like a dust magnet.
Here is the camera bag after two days shooting. One at the beach and one at Red Rock.
