VW Beetle & Minolta lens

Excessive frontal toe value on VW 1302 Super Beetle was corrected into 0,78mm(from 2,50mm in) in direction this morning, generally, total toe value in frontal axle affects on the steering response while turning on the curvature in the transitional phenomena, because it has much to do with Toe Out On Turn angle as a matter of fact. In order to obtain a natural and transient reactions at various speed(mainly at town speed) curve-in and curve-out phase. Insulator application on rear bulk head and floor would be carried out subsequently today.

I won the bid of YaHoo auction on Minolta New MD Zoom 100-200 at very cheap price, only 100yen, feeling sorry against the seller. I'm surprised again to have received the item, it's like new and any defects in this lens were not found at all. Because of lack of flange back distance if set on Canon EOS Digital body, Minolta's silver salt period optical parts do not focus at infinity point. 0,50mm shorter lens set ting position makes the value of MD and MC lenses descend like nothing. This is why they appear in the auction at the cheapest prices. To tell the truth, discrepancy of infinity position can be compensated by lens element adjusting mechanism, removing adjusting sim plates or 1 step turning the helicoid groove in the most difficult designing, depending on the type original design. As for this 100-200 Zoom, sim plate insertion method might have been introduced. For long period of time the same optical designing had bee applied should mean that this one has good enough physical property to satisfy the requirement recently. It would be modified as usual very soon, I'm looking forward to ascertaining it's capability if used on Digital formatting image.
