My friends and photography and hiking buds Kerry and Jasmine did an incredibly nice thing for me. They sent me a Nikon camera rig with the 18:135mm lens identical to the one I already own. Sold it to me for a fraction of its worth. Jasmine went and joined Kerry in Canon land. Like the Hatfields and the McCoys.
Anyhow, this will allow me to keep my 300mm on a camera for the bird shots in the canyon this summer and have a studio or shop camera to boot. Must always have one by my side. This will help. There is no discernible difference between them except a slight difference in shutter feel and a light meter that skews a bit darker. So there will be little or no learning curve. Thank you so much J & K! Death Valley soon!
