Fanime was amazing but it totally left me sick for weeks 
after I got better, I went through the letters I got and found one that had nothing but $20 and a note describing one of my posters. It looked like someone made a mistake and accidentally gave me their money without getting a poster. I want to return that money so If it was you, please e-mail me at Yuumei.yan@gmail.com with your name and address.

My D70s does a f/22 for 30 sec at an 200 ISO. What I want to do is the equivalent f/stop at an 50 ISO.
Here is why: My Coolpix 8700's (backup camera I call Holley LOL) smallest aperature is a f/8 which is 3 steps lower then a f/22, letting in 3 times more light and also is able to do a 50 ISO which is 4 time slow than the 200 ISO.
The Question: What is the equivalent f/stop on the Coolpix using the 50 ISO to the f/22 using 200 ISO?
Update on the D70s: I will be putting Tyra (yes I name my cameras) in the shop on Sat. I did not want to run the risk of damaging her further by again trying to clean up the mess I made. I found a great local repair shop that will charge me just under $50 buck to clean the whole camera.
So if anyone has a answer to my question let me know and how you came to that solution. I will search my books when I get home and if I find out I will post.

ISO200, 30 sec and f/22 to
ISO50, 30 sec and f/?
You loose 3 stops in the ISO, you would need to gain 3 stops back on the aperture. So that would be f/11. However since Holley can only close down to f/8. So you would want to half your exposure to 15 sec. So you get
ISO50, 15 sec and f/8.
Note that this doesn't factor in that the sensor in the Holley is probably smaller than the one in Tyra. So it won't be exactly equivalent.

between f8 and f11 there is a half f/stop.
so it should ISO50, f8, not 30sec but something like 22sec.
