So here it is the 50mm f1.8 that I have heard so much - finally on my nikon d40. I paid this lens purely just for the sake of curiousity. I just recieve it 10 minutes ago an I have tried few shots. I was hoping this lens arrived earlier so I can test it at the easter show, but it does not matter now. Focusing. No auto focusing here, my left fingers do all this super exhausting work designed for the slaves in the medieval era. Metering. It works exactly the same as with the kit lens, perfect. Aperture. F1.8 - F22, the narrowest Speed. Insane. With f1.8 indoor the slowest SS I used was 1/80 on ISO 400. I get used to shooting with 1/8 of a second every now and then, so anything above 1/30 will put me in heaven. I shoot outside and it is cloudy day, the 1/4000 of a second with f1.8 end up with over exposed picture. Since the max SS is 1/4000 I slowed the aperture to f2.2 and still too bright. When I reduced the ISO to 200 than it is just about right. But I shoot mostly with f8 or slower anyway. Origin. Made in China, pretty much like everything else these days except your mother. If we let the American to do these kind of producing job maybe we still playing marbles on the floor. Build Quality. It's a lens that that take pictures - nothing more. And that is what I like, small and light. I did not send the money to buy a hammer mind you. The smaller and the lighter the lens - the better, guaranty cheaper in price. Image quality / sharpness. Don't know yet. So there you go, I have this lens now, no more confusing hear say. What you see is what you get.
