The result on the A900 so far are really really good, even at full open F/2.8.
I have bought this lens for a friend starting photography with very low budget. She is using a Canon Rebel 300D (First model) i have got on Ebay for 200 $ + kit lens 18-55mm at 25 $. She got a 50mm F/1.8 for 100 $ and now i have found the 135mm. Canon confirm focus adapter cost 30$ US, but will be useful for other M42 lens.
More I'm founding those old lens on Ebay and more I'm surprised how they are good on the A900. Thinking that budget wise i should sell my Beautiful Minolta Gear and try to do only photo with very low budget lenses
I know nothing about Chinon, is this company was good in the past ? The full lens description is : AUTO CHINON (in orange) 1:2.8 f=135mm 558120 CHINON IND., INC JAPAN .
