Oh, it might go up to 45/f then.. Hm..

well see when i get it!

cant wait.

Haha, better hope 45/f isn't the lowest. XD

it is.

It can't be. I'm pretty sure it's 2.8/f. Can I see the site from where you ordered it?

i guess its wrong

SQF data indicate excellent performance. There was minimal pincushion distortion (0.45%) and light falloff was undetectable by f/4. At the closest focusing distance of 12.25 inches (1:1), center sharpness was acceptable f/2.8–4, good f/5.6–8, very good f/11–16, good at f/22, and acceptable f/32–45. Corner sharpness was acceptable at f/2.8, good at f/4, very good at f/5.6, excellent f/8–16, very good at f/22, and acceptable f/32–45.


hmm

i just realized i wasted 300USD.....

Haha... My bad, when I said minimum aperture, I meant that it wasn't the small f-stop. 2.8/f is your largest aperture, so you're good. Don't worry, it's just saying that it can make the f-stop go as high as 45/f. That's a good thing.

yeah i thought it seemed a bit weird!

this just made me realize i could of got one for 100USD.....

but it seems a bit fishy....and i know why!

its for pentax, not canon. whew!

so it looks to be that between 8-16 is the best for overall sharpness.
