Re: Some help with my new 10-18mm IS STM please?

Just had a look through my 10-18mm photos and found that most of the landscapes shot above f/8 were not very sharp, with somewhat mushy details. From my own experience, lens performance is optimal across the frame at f/7.1, though somewhat sharper in the center at wider apertures. This suggests that diffraction effects may at least partially explain the OP's results.
