I would love to ask a few here who have already tested their K-7 with a TC, whether a 1.4,1.7, or 2x. would love to know any good results from it in terms of IQ, speed and performance. done in good or poor conditions. with mf or af lens, prime or zooms. any test samples or reviews would be greatly appreciated. as this would also boost up the K-7's stature, not to mention satisfaction from K-7 owners/would-be owners.
I may try some tests myself probably as soon as possible. it doesn't matter who gets to try this one first. goodluck fellas !
