It is Most Definitely Sharp!
A whole lot of you have noticed that I shoot with the 180-400VR a lot, and I mean, a lot! This lens has become one of the most important and used lenses in my kit, using it for birds, mammals, aviation and landscape. This is because of two essential factors that make the 180-400VR a stand out. It has tremendous flexibility and truly unbelievable sharpness. The flexibility comes not only from its zoom range but also its internal 1.4 teleconverter. With a simple, easy and hidden flip of a small lever, you can go form 400mm to 560mm for example (it works throughout the entire zoom range of the lens). In addition, you can add additional teleconverters to the 180-400VR for an even longer range. In this case, I added the TC-14eIII (with internal 1.4x engaged). I’m asked a lot if you can do this and what are the results. Here’s my answer to that common question.
Most definitely, YES and GREAT! Let me start off by saying, this is not a good photo! The gray sky background drives me nuts, it sucks. But in this low contrast light, I don’t have contrast to trick your eyes into seeing sharpness where it’s not. Rather, it’s the mind-blowing quality of the 180-400VR (with internal 1.4x engaged) with the TC-14eIII (making it 784mm) that is bringing you the sharpness (shot hand-held). This is not a lens for the faint of heart, its price and weight should make all shooters stop and think if it’s the right fit for their kit. But those who do dive in, rest assured, it will exceed your wildest expectations. It sure has mine!
