Having been using this lens the past 6 months with awesome results. The 1.4 built in TC is such a bonus. Well worth the money.

This lens is a dream come true. My husband bought it for me for my birthday. The built in TC is a game changer! I shoot handheld most of the time and I never struggle.

An absolutely brilliant lens! Its MFD is stunning, its balance perfect and its loss of weight a must. These attributes though as out shinned by its sharpness! The Z600f4 is a spectacular lens!

A wonderful lens that gives you options when you need a little more space or need to get closer. The internal TC works great; you can hand-hold it for a little while too. Being able to just flick a switch rather than take off the lens and put on the TC is huge. Images are sharp and it's a joy to shoot with. Paired with the Z9, I find it aquires subjects quickly. The 800 is also wonderful and lighter and just as sharp. Having owned the old 800 too with the D850, I find this 600 is lighter and much easier to hand hold, though I'd recommend a tripod if shooting for an extended period of time such as birds coming into an area with food and water. The bottom line is this lens is really like 2 in one; there's no loss of detail with the TC, and owning the 800 I can't tell any difference in sharpness between the two lenses shooting at 800 (840 5.6 on the 600). Having the ability to go to f4 for a little more light is great too when light gets lower. Expensive but worth every penny for great shots. Nikon has hit a home run on both this and the new 800 6.3.
