How low do you go?...f-stop wise at DVinfo.net

Jamie Roberts · October 19th, 2012, 06:29 AM

Hi,

How low do you stop down your fs100 to in daylight conditions and still maintain a decent quality image.
This would be without using any ND filters and using the 18-200 lens or sal1650 or similar (they vary in what they will close down to don't they?)

Reason I'm asking is in looking to get shots with deep focus outside and keen to know others thoughts on optimum f-stop settings without losing quality. My experience has been that closing down a camera lens too much can make the image soft and a bit ugly.

Thanks

When snapping Pictures I never go past 7.1 and stay as high as 5.6. I keep the same mentality when I was shooting video with a DSLR keep it at f8 max. Now on my AF100 I stay at 5.6, max F8 sometimes and ride the shutter and thankfully ND-filters. If I had the FS100 I'd ride the shutter as much as I can while keeping the Fstop as high as f8 but if I need more then I need more since I don't have nd-filters.

You don't have the same issues due to the diffraction limit with the FS100 that you have with dSLRs and other high megapixel cameras. Feel free to spin the dial past f/11 and up to about f/16 before it even begins to affect the image. You will start to see it as you go from f/16 to f/22.

Even at an f16 in bright sunlight you're going to be overexposed without an ND filter, assuming your'e shooting at a 1/48 shutter speed, for 24 fps.

Just finished doing (amongst other things) slow shutter timelapse in Floridian midday sunshine.

Deffo got diffraction at f22 - not ugly but getting soft, compounded by using a Vari-ND at the very edge of its ND-ness. Note to self: 16 is probably a good safe limit.
