Did you go to your e-mail and activate? This is a new game and I see you are not registered.

I got it Randy.
Thanks.
I think the answer to #8 is incorrect.
Changing the aperture will not change the focused distance.
It will change the depth of field.

I got it Randy. Thanks. I think the answer to #8 is incorrect. Changing the aperture will not change the focused distance. It will change the depth of field. Mickey i was curious so i went and had a look, I figured out how to sign up and do it..but i couldnt find that question there...so i could not see what your choices were.. perhaps it was a bit of a trick question..on one hand changing the f stop does change the focus distance 'if' you are refering to how the focus distance changes in relation to how the F stop selected changes the hyperfocal distance ...as an example, with landscape photog you alter the focus distance point, for different aperatures to maximise your best depth of field..as opposed to say portrait photog where your distance is pretty much already determined and altering the aperture is just altering the DOF...splitting hairs maybe  |

Mickey: I agree about #8 in that quiz. If you have a specific point in focus, that point will remain in focus no matter the F-stop. Areas in front of, or behind may change due to differing depth of field, but not the specific focus point. The question, IMHO, was poorly written. Today? I doan' know nuttin from no Nikon!  ;D Roy |

Andrew,
The point of focus and the hyperfocal distance should not be confused with each other.
The point of focus is the specific point upon which one focuses a lens.
The hyperfocal distance can, indeed, vary with aperture variations at which instance the point of focus would be altered manually to the hyperfocal distance.
I tried to go back to the question to make sure I hadn't once again put my foot in my mouth but I couldn't get there from here.
I am reasonably certain the question did not refer to the hyperfocal distance though.
I am vehemently opposed to splitting hairs as I have far too few muck about with.

Randy - I think Mickey is right, the question was about focus, and implied the point of focus, not the hyperfocal distance, so either the question was too vague, or the answer the trivia game considered correct for #8 -- in a word, isn't.  |

I'm innocent, I just posted the game, I didn't make it.

I know, Randy ... just pulling your chain. The second trivia contest is a doozy ... my brain was in neutral, and it shows! |
