Re: Picture sharpness on Canon M6 ii with Tamron 100-400mm

Thanks everyone for all your feedback!

Good to know that it is likely down to the distance rather than equipment - though somewhat disappointing as well, as I hoped this lens would allow me to exploit the M6's high resolution to the fullest and really crop a lot (those kingfishers tend to be on the other side of the river...)

OP, to be completely sure there is no issue with your lens perhaps find something bird-sized with some fine detail (like a toy bird etc) and place that around 5-15m away and take some photos and we can get a better idea on how it is performing. Looking at the detail around the pipe and wall in your photo it looks optically great, but I have seen reports of mis-focusing at the different focal lengths where the tap-in console may assist so will help isolate if there is a possible issue.

As for the experiment you're proposing, is the idea to have a relatively small subject so that it is clear where the focus is supposed to be, and then check if the focus under/over-shoots as I move the subject further away for each shot?

I'd be very curious to try it, just wanted to understand what the aim would be!
