Q: 2. It has been written that this lens does not have a back glass element to protect the back of the lens from dust. What have been your experiences? Some say that if you attach a converter to the back of the lens,it helps prevent the dust from entering. Seems expensive.Does this lens work equally well with both DX and FX cameras? Are the images sharp?I am going on a once in a life time trip to Africa. Will this lens be useful in catching the chase ?Your thoughts .

A: The Nikon AF-S NIKKOR 300mm f/4D IF-ED Lens does have an unusual rear aperture and does lack a rear rubber gasket. However, I feel it very unlikely that real image compromise due to dust would occur with this lens. In fact, the far greater reality is dust on the camera's sensor. With this excellently sharp lens that is good for either DX or FX cameras, I say just exercise normal caution when changing lenses.Since animals are rarely close enough and they move unpredictably and quickly, I would suggest you might consider longer zoom lenses such as:Nikon AF-S NIKKOR 200-500mm f/5.6E ED VR Lens (Refurbished) B&H # NI20050056VQ Back ordered, no date set but affordable. Nikon AF-S NIKKOR 80-400mm f/4.5-5.6G ED VR Lens B&H # NI8040045GED very high quality.Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary Lens and TC-1401 1.4x Teleconverter Kit for Nikon F B&H # SI1506005CCN Affordable, sharp, and with an extender included.
