I take photos for fun, mostly at zoos to make my own desktop wallpapers and wall art. I got my first impression of this lens when I rented it. At the time, I was using an 18-200mm lens (lol). I was heartbroken when I had to send this lens back after the rental period ended. This lens spoiled me, and could no longer tolerate my 18-200 lens. Before buying this lens, I kept asking myself why I needed to spend so much money on just a lens when all I do is take pics of animals at zoos. I think my heart skipped a beat when I hit the "purchase" button. But over a year later, Im still so glad that I bought it. This lens solved several problems for me that I was having with my 18-200 lens, which were soft focus, chromatic aberration, faster autofocus, edge-to-edge sharpness, and edge-to-edge brightness; and at f2.8, allows faster shutter speeds in lower light. Ive also used this lens on a D800E that I rented. Upon careful inspection in Lightroom, I could see a very small amount of light fall-off around the edges. So slight, that its easy to miss and even easier to correct in software. I was tempted to buy the 70-200 f4, but decided against it because I would lose a stop of light. Sure the f4 version supposedly has better VR, but what if you dont need VR? Youre still stuck at f4. With all this said, this lens is big and heavy. Its not a casual lens. Youll be the one accommodating this lens, not the other way around. It took me a few months to become fully comfortable using it and carrying it. I use a BlackRapid Strap ( BlackRapid RRS-1BB Sport (RS-Sport) (Black) ) to dangle the camera body and lens at my right side, lens pointing straight down. Some side notes: From my experience, this lens is waterPROOF, and so is the D7100. I got caught in a downpour here in Florida and the body and lens got drenched. The lens fogged up, the cameras viewfinder filled with water. I put the lens and camera in airtight containers with dehydrated rice for a few days and all the moisture was absorbed and both worked like new! Ive used this lens with and without an expensive clear filter. No difference in quality, so I leave it on. Id rather have light "cleaning scratches" on the filter than on my expensive lens. Without the filter, I would have to resort to my cleaning kit and spend a lot of time carefully cleaning the bare lens. With the filter, I use my shirt! For best auto-focus results, half-press the shutter button for a few seconds before taking the photo. This gives the VR time to counter the type of vibration its experiencing in that particular situation.
