Summary: I bought this lens to act as my walk around lens. I use a D7100 and this is somewhat equivalent to a 50mm on a full frame sensor, which is what I was aiming for. F2.8 is good enough for me. P.S. I also bought this lens along with others to get rid of zoom lenses. I have a 14mm, 28mm, 50mm and 100mm. Works great.
Summary: Es un objetivo muy bueno no es un "pro", a distancias cortas funciona muy bien, al infinito no tiene el mismo funcionamiento. En fotografía de arquitectura saca bien líneas rectas, No es tan bueno como el superior Nikon AIS 28 mm. F/2, el cristal amarillentto rosaceo de la lente de éste, tiene un contraste y resolución en la línea más alta, en sus aperturas centrales.
Summary: I was rather disappointed with the 28mm f/2.8 as a whole. The IQ, contrast, and sharpness are subpar from the perspective of a Nikon traditionalist. I frequently shoot with some great lenses on my D800...a 135mm f/2, 105mm f/2.8 VR, 70-200mm f/2.8 VR and 14-24mm f/2.8 all producing incredibly detailed poster sized enlargements with sharp detail. However, the 28mm just couldn't compete.
Summary: I bought my 28mm F2.8 lens second hand for about 120 dollars and it came looking brand new with a filter! I used it on my (second hand) D700. When my daughter was born, I was allowed to take my camera in the delivery room and I had to take one lens with me. I chose the 28mm f2.8, that says it all! My other lenses were the 50mm f1.4G, 20mm f2.8 and 24mm f2.8. So why the 28mm?
Summary: I like this lens. It's very light to carry. It focuses fast and sharp. I only had problem with the aperture lock/ring. That when I change it to another F, it always turn error. SO I had to fixed it to the max aperture, 2.8F. But I guess because my cam is D7000, not an FX. Very useful if you're just in a small room event. Very wide shot, that is. I'll keep this one. .
