Report "My friend dropped her Tamron 28-75mm 2.8 lenses from a cliff to the salt water. I rescued it and as we know, the electronic part does not work anymore but the mechanic does. I toke all the parts apart and take all the sand and cleaned the lenses. Put all the parts back, with everything. One detail that I didn't pay attention was the position of the first lenses (the ones near of the aperture ring). My question is, do you have a manual of disposition of the lenses available? Or a step-by-step mounting the lenses? Thanks!"
