Easydive Leo 3 Wi in Photography Gear and Technique Posted December 8, 2020 I haven't noticed any lag with a nikon dslr, no, though I haven't taken it down for macro shooting where I'd notice it the most. The button interface is... different? For example, I'm used to twisting a wheel for modifying f-number or shutter speed, and now I need to push a button, one for each position. I guess this doesn't affect me much because mostly I'm tuning or changing multiple values (enter/leave wreck, change ISO, shutter, aperture) in which case it's much faster. But changing from a 30 second long exposure to 1/200 probably takes a lot of button pushes, whereas before it'd just be a few spins. What required the most change was the half-press of the shutter release to grab focus. This now is a different button from the shutter release itself.
