I found a Black 65 series F with black Photomic T head, 50 I.4 S 28 f2 35 f2 55 3.5 Micro, 105 2.5 Sonnar type in lightly used condition for $275 glass is excellent. All but the 50 1.4 have been AI'd . The F is not a red dot unfortunately but was precision engineered to take the Photomic T head. The Micro Nikkor, 35 and 105 were precision engineered to AI by non Nikon engineers but the 28 is factory adapted. Not a collectors set. There also is the adapter plate for an F36 and the battery pack but no drive: so either I need a drive or someone want to trade something for a battery pack?
