random: but it's spelled 'TACK' sharp, not 'TACT' sharp (correct?)

or am i wrong? i keep seeing 'TACT' written on the forum by other members, which made me wonder what the hell 'tact sharp' is, lol.

Tack for me. Tact doesn't make any sense.

Do a google image search for "tack"

Which will bring you up a photo of a tack, which is sharp.

So I totally agree with your comment about len's sharpness. Alot.

No one here has the tact to correct those not using tack correctly.

LOL. though with the tact of some people - it could be dual meaning!
but to answer the question - i agree. the saying is tack sharp....

but you guys, you don't get the point of this thread.

yesterday i bought my new 50L, but noticed it suffered from focus shifting with up close subjects. i sent it in to canon, and since it was under warranty they did it for free. but since i was already close to irvine, i just whistled for a cab, and when it came near, the license plate said fresh and it had dice in the mirror. if anything i can say is that this cab was rare, but i thought 'man forget it' - 'yo home to bel-air!'

Hey Alot: Who mentioned Len, and shouldn't his name be capitalised?

Sharp as a tack

Or

Sharp as a tact
