I'm looking at two nikon 300mm lenses, need advice? |
Both are 70-300mm and price aside, one is much larger, and heavier and has a larger filter size, front of the lens is larger. but they are both f/4, so my question is are f/ numbers relative to anything or do they corrospond. I'm interested in sports photography and need the faster of the two. I'm actually seeing three Nikon 70-300 zoom lenses at B&H Photo. Here are the lenses, prices, and links to Rockwell's reviews of each lens. Nikon Zoom Telephoto AF Zoom Nikkor 70-300mm f/4-5.6G Autofocus Lens - $139 http://www.kenrockwell.com/nikon/70300g.... Nikon Zoom Telephoto AF Zoom Nikkor 70-300mm f/4.0-5.6D ED Autofocus Lens - $320 http://www.kenrockwell.com/nikon/70300af... Nikon Zoom Telephoto AF Zoom-Nikkor 70-300mm f/4.5-5.6G IF-ED AF-S VR Autofocus Lens - $480 http://www.kenrockwell.com/nikon/70-300-... See also: http://www.popphoto.com/cameralenses/385... See also: http://www.bythom.com/70300vrlens.htm... Clearly, the bigger lens is the way to go. All those letters mean something and each one adds a few more letters. The first one is just your basic, acceptable Nikon zoom lens. The second one adds some "ED" glass (extra low dispersion - a sign of quality). The third and bigger one adds VR and AF-S. VR is "vibration reduction" and will greatly enhance the sharpness of your pictures, especially at the long end of the zoom. AF-S means that the lens includes an integral focus motor and it can be used on ALL Nikon dSLR's, including the D40's. This particular lens is at the top of my own wish list. If you have a real thirst for quality at the 300 mm end, check out this baby! Nikon Telephoto AF-S Nikkor 300mm f/2.8G AF-S ED-IF VR (Vibration Reduction) Autofocus Lens - $4,499. http://www.kenrockwell.com/nikon/30028vr... The larger one could be the VR version which is 67 mm filter size vs. the non-VR which is 62 mm. The VR is about $130 more and even though it is 4.5-5.6 vs. 4-5.6 the VR mode can give you 3 to 4 stop better. This means you can get a clear shot at much slow speed, i.e. the non-VR at max zoom (300mm) at wide open f-stop (f 5.6) will require 1/250 and steady hand to get a clear shot, while with a VR you can get a clear shot (same f-stop and zoom) at 1/60 (that 3 stops). Bottom line get the VR. Also if you are using a digital body, then the equiv zoom to 35mm film is x1.5, in other words your 300mm is not 6x but 9x the telephoto. http://www.nikonusa.com/template.php?cat... http://www.nikonusa.com/template.php?cat... |
