I probably won't be back much to check this page. But if you need to contact me, I guess this is good a place as any.

S3 IS super macro zoom hack

I have not had the courage to try this hack on my S3 IS, I am wondering how much the depth of field drops off when you zoom in in super macro mode. How much can you zoom in and still have focus? HighInBC 17:34, 16 June 2007 (UTC)

When I use manual focus set the closest: At widest-angle zoom I can focus on something as close as 2mm from the front surface of the lens, and when zoomed-in all the way (zoom step 128), I can focus at about 55cm, or about 22 inches. When manually focused to infinity, and zoomed-in all the way (step 128 zoom), I can focus on something about 3-4 meters away. The DOF becomes just as shallow as if using close-up filters in zoom mode or with a tel-extender + close-up filters. With that much focusing range this FAR surpasses any effects and features I can do with add-on lenses. Not to mention turning it into a fantastic portrait lens with a super-shallow DOF for tight face shots. When zoom is set to step 64 (halfway), I can focus on a ruler about 13cm (5 inches) from the lens and the FOV is about 2.2 inches. At zoom step 32 (1/4th zoom) FOV is about 4.5cm (1.5") about 2cm away from the front of the lens (one thumb width away).
SO ... this is am amazing feature. I just wish I felt safer putting my camera in that mode. I hate hearing those thudding and buzzing noises. I thought I'd risk it again to answer your question, because it got me curious what the ranges are with the lens "tricked" into acting this way. Once the lens is in this mode, it doesn't appear to make any disturbing noises anymore when focusing and zooming at any speed. It's just when it gets triggered into this mode does the camera make disturbing noises. The lens has reset safely every time I have turned the camera off and on again, but .... from the sounds the camera is making, it still sounds risky to use this!
