Re: Unboxed, with a light review
Hey Timur
Nice review. How are you rating the ISO values on the camera? The production models still list gain in dB values. Was your -6db rating the 280 ISO value? Just curious. Andy

Re: Unboxed, with a light review
The scale built in to the camera suggests the following.
ISO280 - -3dB ISO400 0dB ISO580 +3dB ISO800 +6 ISO1100 +9dB ISO1600 +12dB ISO3200 +18dB My thinking is that Sony rates the F3 @ ISO800, and there lies 0dB. But it would perhaps seem unorthodox to have a -3 dB -6dB and -9dB on the scale. So to follow broadcast tradition, they placed 0dB squarely ln ISO400. It seems the camera performs best, interms of dynamic range and noise performance around ISO400-ISO800.

Hi Timur,
I appreciate the time put into your blog, especially how you shot certain scenes. So, which camera do you prefer and why: AF100 or F3? |

Re: Unboxed, with a light review
Thanks Timur!
I rated the camera differently in quick test, we got 0db around 800 ISO. However +18db didn't seem to be much over 2500. Wasn't very scientific, but I'll break out the meter tomorrow and see what I come up with. The gamma mode will play a part in this so I'll adjust accordingly. I agree that the 0 to +3 db range seems to be the best in terms of performance and dynamic range. Andy

Re: Unboxed, with a light review
Did -3DB have any negative affects(i.e. loss of highlight range)? I imagine it could be useful in cutting depth of field.

On a side not, I tried an F3 w/ the new Leica PL primes today at Bandpro East. WOW. You haven't seen sharp, till you've seen these lenses.

Re: Unboxed, with a light review
I am not sure. I would need a step chart to determine that. When I have access to one, I will be sure to report all findings.

Re: Unboxed, with a light review
There's an easy test that works with the EX3, might work on the F3. Enable the spot meter, point the camera at a high light that blows out reading 109%, switch to -3db, same highlight peaks at 105% and nothing will read higher.

Re: Unboxed, with a light review
Timur doesn't play around! The lenses and tripod cost as much as my house! ;-)
