I’ve had the lens for a few months and absolutely love it. Having said that, I find it extremely difficult on frame filling images without a TC to prevent the images from appearing over sharpened. I have an import preset for LRC that keeps sharpening at zero. If I use DXO pure raw or topaz denoise I have the sharpening sliders at zero. I rarely increase texture and if I do it’s very minimal. I don’t have this problem with any other lens other than the 90mm macro. If I use the 1.4 tc with the 600 this isn’t an issue, although still very sharp. I realize I can go in and mask the subject and reduce sharpening and other things to help to an extent. Just curious if others run into this and what you do to rectify it.
