a77 resolution revisited

I have made som photos. Distance about 23 m from the ruler. Lenses in the following order: Tamron 90 mm, DT 16-105 at about 90 mm, 70-300G at about 90 mm. f 5.6 for all. At 23 m I cover 6 m on the long side (90/24*2300=6000). Is it good enough? OK, the weather was not the best. Used tripod but forgot to set SteadyShot to off. Also both Tamron and 16-105 are used with polarizer. Exported from Lightroom with 2000 pixel at long side, 300 dpi. Jpeg.
