my extension tubes were i think $10 , from Singapore or someplace, not auto focus and the instructions were in Chinese...which i don't speak

...ignored the counsel i received here to get the kenko ones....i did get them right after i got my camera so maybe i should pull them out and give them another whirl...the filter-ish macro lenses were also about $10 and work about as well as putting your lens inside a drinking glass and trying to look out the bottom end ... you get what you pay for sometimes

i'm sure a canon or even a third party would work better
samples all on a tripod inside with lousy lighting
50mm1.8 canon with chinese extension tubes
28-135 canon with filter type lens thinkthis is +4 or +2 cant'remember which i used( sonia brand)..need we say more..is was turned off by the way
phoenix 100mm macro lens with out 1:1 filter, so 1:2 ratio
as you can see i wasn't exaggerating...and when i went to use them i remembered 2 of the biggest problems with the tubes...1) it got stuck on the camera so a few moments of panic till i could get it lose( remembered that as soon as i tried to remove it hehe) and 2) guessing it's because there are no electronics involved but you can't change anything on the lens ie aperture, shutter so maybe if you had an old manual aperture lens...i guess you could set the lens for a stop. this one is with the 1 ( smallest ring) but once you add rings, it gets overexposed....maybe if i could read the directions it would help
imo the phoenix for around $100 used on ebay, $150 new, isn't
that bad but i have a hard time using the 1:1 filter...i might need more light for it cause my autofocus won't focus..i was inside on an overcast day so i didn't even try. manual might work better but i've only used it a few times. if i can't get better results this summer when i can take it outside and mess around with it i'll probably sell it and get the canon for around $400 new...which is why i got the phoenix to start with

originally i figured it would do for now till i got a few other things i want then i can sell and get a better one.
