fun focus facts???

[jann1033]

ok my $10 china tubes are causing me a plethora of problems but till i get something else a couple ???

it dawned on me ( after everything was overexposed... duh...) the metering isn't working either so is that just a trial an error thing or would there be any range i would figure for something macro( i was using 50 mm f1.8 lens and actually got it on and off the body with out a hitch ..hooray for that) or any tricks...like would bracketed exposure work..i'm guessing not since it's electric?
guess you really are going back to pioneer photog days using these things.

nother dumb ? i was looking up adapters for lens and they mentioned about no af, no meter , but talked about setting it to infinity...what exactly does that do...i know the little infinity symbol, but wonder when you would or would not use it...and if auto focus doesn't work how would you get focus ( if i understood it right) for a larger range using infinity? just due to lens construction?
http://www.vividlight.com/pdf/hyperfocal.PDF.. this is for hyperfocal point which i am guessing is presumed more useful than infinity focusing unless it's the moon or something but would any apply to a small sensor dslr? not that this would help with macro but guess i am just trying to figure out the best way to manual focus for a trifocal wearing novice.

well back to my reading and thanks for any help

honestly, I do it the dumb way, just keep twisting the focus dial until I get it the most focused, then I move the camera closer/further from the object to get even better focus, then use the dial again to ge the best focus

note: the above is for macro photography w/ manual focus only

in terms of exposure, you can only do trial and error, unless somebody like we-luv-disney or 0bli0 can tell me how to do it better (I personally use a light meter but that's extra $$ to be spent).

thanks maybe i 'll add a meter to my list of things to look for...i might be able to find one reasonably since probably most don't use them with in camera metering

I think the acceptable ones run about $500 ish

ok that's way way way down at the bottom of the list.....
