Pros: this one seems to work OK. I've only tested usb sticks and SD cards in it, but the similar usb3 all-in-1 I got a year ago never worked right.
Cons: it would be very cool if there was a soft amber or green led inside this so the slots were backlit so I can tell where to plug stuff in my black case under my desk when the room lights are low. I'm thinking of modding mine.READ FULL REVIEW
Pros: inexpensive lower-mid range Geforce card.
dual DVI is exactly what I needed to run my dual monitors
GT640 doesn't require any aux power connections.
plenty fast for google earth, stellarium, and simple 3D modeling software.
Cons: just OK for basic gaming at moderate resolutions. thats OK, I don't game.
Other Thoughts: this is at least twice as fast as the onboard HD4000 on my Core i5-3570K, but more important, turning off the HD4000 speeds up my CPU. With it off, my CPU is rock stable at 4.2Ghz, so using this board is a win-win.READ FULL REVIEW
This review is from: Opteka 85mm F/1.8 Manual Focus Aspherical Medium Telephoto Lens
Cons: really cheap.
I was sort of hoping 2013 China could make a lens as good as 1966 Japan. Dream on.
wide open this lens is total mush with ghosting. you need to stop down about 2 stops before the blur gets even remotely OK.
ugly bokeh. one of the reasons for a fast portait lens is to achieve shallow depth of field.
the focus is far rougher than my 1960s pentax thread-on M42 lenses. the iris only has whole stops, and not even ones, f/ 1.8, 2.5, 3.2, 4, 5, 7, 11, 22. the iris is rough to turn too. the exterior finish of the metal is pebbly rather than satin. the lens hood is an integral part of the lens, the lenscap fits on the hood not the lens. I'm not sure you can use a filter with this.
there is a fair amount of purple ghosts on contrasty edges off center... this is chromatic abberation, far more than I'd expect on an APS-C camera with a 85mm lens.
Other Thoughts: I got this lens to do wide field astrophotography, and still lifes. I haven't tried it yet on the night sky, the full moon had too much glare last nightREAD FULL REVIEW
