The Fujifilm GFX 100 vs Salt Water Teardown
*Lensrentals.com, 2020* So today is “Every Dark Cloud Has a Silver Lining Day.” The dark cloud involves a Fujinon GFX100 medium format camera that went out on rental, got used in a dive housing, and ‘suddenly died for no reason.’ Except on further investigation, well, maybe it got a little wet, but…

Photography Fundamentals – How Shutter Speed Changes Your Photos
