A while ago I bought a Tokina 24mm f2.8 FD mount, but I was not happy with it: bad contrast, bright spots smeared out, lack of sharpness, cold colors.

I recently bought the FDn 24mm and the difference is huge compared to the Tokina, in a positive way.

I use it with my NEX 5N so it's actually a 36mm lens. The color, warmth and contrast is comparable with my Canon FDn 28mm and 35mm lenses, rather nice.

It's a little heavy compared to the standard NEX lenses, but not too heavy.

Build quality is very good as most older lenses.

A very nice little lens with good bokeh, much better then the FDn 50 mm F1.4. There is nothing that spoils the fun. I use the 24, 28, 35 mm with a adaptor on a digital Sony nex (* 1.5) . I can use the same suncap on these lenses. F2.8 is fast if you compare it with zooms and for these lenses fast enough.

This is a nicely made, solid, light weight lens. Nothing extraordinary here - no exotic glass or aspheric elements or a super-wide aperture. With wide angle lenses, I'm more often than not interested in obtaining lots of depth of field so, as I'm usually stopping down quite a bit, a maximum aperture of f2.8 is not a problem. With that sort of specification, no fancy optics are required to get good image quality. This lens delivers. It is largely free of distortion, and images are sharp. What more can one ask for? (Well, OK, a brighter image in the viewfinder would be nice, but I'm not quite sure that's worth paying for in size, weight and cash, at least not for my needs.)

My widest FD to date. A solid performer with good color rendition and very good sharpness. This lens is always with me when I take the old FD stuff around the block.
