The Crossfire HD 12x50 binoculars are awsome. I use them for birding, wildlife spotting while doing nature photography, and while bow hunting. They are bright and clear. Being a photographer I have an appreciation for fine glass, the Vortex Brand has never let me down. I also purchased the Vortex Razor UHD 10x50. The light gathering ability is the same. The visual calarity in the center is very much the same. However the edge to edge clarity of the Razor is superior. If you have a small subject and keep it in the center of your view, you'll be hard pressed to see any significant difference. The Crossfire HD 12x50 is an outstanding choice. They are slightly smaller and lighter than the Razor model. Very happy with the Crossfire model, for long days in the field.
