Almost all old lenses struggle on modern High resolution sensors.... remember this lens was designed for film, without getting into discussion about the resolution of film but at the time "high resolution scans" were around 5 megapixel.....
Downsize to around 8-10 megapixel which is enough for most printing and most screens and you will see it's still usable.
If you are after the ultimate per pixel sharpness you should look elsewhere obviously
