. . . for your excellent web page compiling all of the photos and stats on your Minolta lens page. I spent many hours bouncing back and forth between your page and a couple of other Minolta lens pages while shopping on eBay for a legacy Minolta 135mm lens. I wanted an MD mount lens to use on my Pentax Q and my NEX, and I knew that there was a wide variation in features. I wanted the best lens at the lightest weight, especially since the little Q is not nearly as forgiving with an adapted lens as the NEX. I looked at a lot of listings; I even found a couple of lenses you don't list, an MC Tele Rokkor-PF 135/2.8 and an Auto Tele Rokkor-PG 135/2.8. It appears from my readings that beast was one of the earliest Minolta 135 lenses from around 1959; intriguing, but not what I was after. I also gave strong consideration to the MC Tele Rokkor-QD 135mm/3.5 due to its 4/4 design and the comments I'd read about it. In the end, it came down to an MD Tele Rokkor-X 135mm 1:3.5 and a pair of MD 135mm 1:3.5s. All were in very good condition, but the Tele Rokkor-X was in mint condition in the original packaging for only $40 USD, shipped. The fact that it is 20g lighter is icing on the cake. I did hesitate on the later lenses because some have claimed the 5/5 construction is not as "sharp" as the 4/4 construction of the 1:2.8 lenses, but I wonder if my eyes would even notice the difference. I also read that the coatings on the late model MD lenses were more flare resistant; I hope that is correct. I know it takes a lot of time to put together web sites like yours, so I just wanted to say thanks. Tony PS: The 135 on the Pentax Q gives an equivalent of 765mm. Makes the Pentax Red Dot Sight I bought come in handy.
