Sample photos
In this long-term review of the Nikon D7100, DC Watch at Impress posted up several full-resolution photos taken with the 28-300 VR lens. Other lenses used were the Nikon 16-85mm VR and Nikon 60mm f/2.8G AF-S Micro-NIKKOR.
There are 5 official Nikon 28-300mm f/3.5-5.6G VR sample photos posted up on Nikon Imaging. None of them are available at full-resolution, however, they are large enough for you to reasonably judge color, contrast and bokeh with.
Standard / optional accessories and add-ons
The manual mentions the following included accessories:
The 28-300 f/3.5-5.6G VR accepts filters with 77mm thread size, which means you’ll want to be looking at purchasing 77mm filters. Nikon also makes their own filters, namely 77mm Circular Polarizer II, 77mm Screw-On Soft Focus Filter and 77mm Screw-On NC (Neutral Color) Filter.
The full list of compatible accessories is available at Nikon USA.
