Originally posted by disasterfilm I think forum concensus is that Prime + TC has better image quality than the extreme length superzoons, if IQ is your be-all and end-all.
Extra info: I have an F* and it is every bit the legend that its reputation suggests. Compact and brilliant. I'd be attacked wildly if I revealed how cheaply I bought mine too (the seller thought the AF was broken... he didn't realize all you had to do was slide the MF clutch to AF... a happy surprise when the package arrived).

Dang, that's a lucky find on that "broken" F*...currently eBay only has one maybe VG condition judging by the pix all the way from Japan. Are the F* and FA* optically better than the DA*300, on paper you lose a half (or 1/3?) stop, 4.5 vs 4. Or is the main issue the SDM worries with the DA*, though there are guides to disable SDM in firmware and or tricks to try and unstick malfunctioning ones. The DA* is a few ounces more, but with the SDM disabling hacks and at least a better possibility of getting repairs on other parts would it be an OK tradeoff?
Is there only one version of HSM Bigma, or if I see HSM on eBay wherever it could still be an older version? At the price of a new one I'd maybe go for a DFA 150-450, less range but reviewers seem to mostly rave about its overall performance.
Lots of 645 A*300 available for whatever reason but precious few K mount /f4, true. And the 2.8s, I need to get back in the gym before attempting to tote one of those howitzers. Plus the entry price, whew, you're _really_ paying for that, full stop.
