Unboxed, with a light review
 
Got my F3 2 days ago, w/ Cooke Lenses.

Some initial thoughts. Real testing will take place on Sunday.

I will be updating the findings. Check back.

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.

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?

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.

Did -3DB have any negative affects(i.e. loss of highlight range)? I imagine it could be useful in cutting depth of field.

Well, I helped create and beta test the AF100. It's. not quite what I need in my career. I needed something with more punch. The F3 was it for me. Its sharper, cleaner, and has betterdynamic range. In my opinion the choice was clear.

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.

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.

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.

Timur doesn't play around! The lenses and tripod cost as much as my house! ;-)
