Digital Cameras Photo Reviews of Sigma 50mm F2.8 EX Macro Lens for Nikon-AF CameraCustomer Review: Thumbs Up!! Summary: 5 Stars
This is a dandy lens not only for macro photography, but for general purpose shots as well. I use this lens for shooting lightning at night and plan on trying it on fireworks this year. This lens will open up to 2.8 which places it in a relatively fast category. I have taken some very nice lightning images this spring with this lens attached to a Nikon D200. Although it's in the 75mm range given the 1.5 magnification factor of the Nikon DX APS sized sensor, it still does great work on lightning if the action is in a small area of coverage. But since I photograph storms that are several miles away, I still can get a large part of the action in view with this lens, and it is fast!! As far as the macro aspect, I've done various images of flowers and it's not difficult to fill the frame with a floral subject. Depth of field is quite shallow, but you expect this. Images are super sharp, and for the money, in my opinion, this lens is a steal!!
