I tested two AI/AIS lenses against their modern 1.8G counterparts over the last week, concentrating on resolution at landscape f/stops. The 28 1.8G trounced the 3.5 AI across the whole image frame, while the 85 f/2 AIS has held it's own/surpassed the 85mm 1.8G (still testing). I don't have time to make crops this weekend, but I'll post the .nefs to Dropbox if anyone is interested.
The 28mm f3.5 isn't known for greatness. Put the 1.8G up against the 28 f2.8 AI-s, and you'd have a better comparison.
