I have two R6 cameras and tried both with my ef 600mm f4 lens and it is not sharp... both work great with all my other EF lenses. Common problem? fixable?
why do you think shutter speed is too slow when unit is mounted on rock solid tripod? I consistently shoot 1/40th sec with my 500mm f4 and SAME 1.4 TC with tack sharp results.
I shoot manual, single and continuous high, single shot and servo. lens is missing focus all the time. lens is an IS lens so I guess ver. ii444A0113.jpg444A0102.jpg
