I ended up ordering an older 60mm "C" *T 3.5 from keh
Only problem is it didn't ship until the "estimated DELIVERY date" so it wont arrive until next tuesday.
I highly recommend you pay the extra (2 dollars usd in my case) shipping fees to get them to process the order faster. (I actually did select the UPS 2nd day air but a website glitch didn't process it as such)
My order took just about 4 full working days to ship.
I'll report back once I've tested.
I have a 50 also but that requires a certain composition due to the good amount of foregrond included with the 50 on a 6x6 frame.
I'm hoping the 60 will be a bit better for me.
