Sigma 150-600mm / f5-6.3 DG OS HSM Sports A1  The workhorse for my wildlife photography. Professional build quality. Dust and splash-proof sealing. Zoom lock (yes!). Compatible with Sigma USB-dock for user customization and adjustments via computer. I’m impressed about sharpness, bokeh, and color quality. The lens needs good support because it is heavy, but with proper technique it can be handhold and delivers very good results.  ★ ★ ★ ★ ★
 Nikon AF-S NIKKOR 16-35mm f/4G ED VR  This is my favorite for landscape photography. A wicked sharp lens. Highly recommended!  ★ ★ ★ ★ ★
 Nikon AF-S Nikkor 70-200mm, f/4G ED VR  I have acquired this lens mainly for my landscape photography but its light weight makes it very versatile and I started using it for wildlife as well. Sharp and fast focus.  ★ ★ ★ ★ ★   
 Nikon AF-S NIKKOR 24-120mm f/4G ED VR  My walk-around lens for many different occasions. The lens is very sharp. The only thing I dislike is the lens creep that occurs easily if you carry the lens with the front element pointed down.  ★ ★ ★ ★
 Carl Zeiss Distagon 35mm f/2 ZF T*  This is a manual focus, auto-aperture lens. I use it mostly for landscape and travel photography. Superb sharpness, exceptional contrast and color.  ★ ★ ★ ★ ★
 Sigma 150mm f/2.8 APO MACRO DG HSM  Macro lens with true 1:1 magnification. This is the older generation without optical stabilization. Sharpness is very good but focus seems a little slow sometimes. The newer generation might be different. I use it in my wildlife, landscape, and occasionally for concert photography.  ★ ★ ★ ★
 Sigma APO Teleconverter 1.4x EX DG  Most of the time I use it with the Sigma 150mm f/2.8, which makes it a 210mm f/4. On the Nikon D300s it becomes a 315mm f/4. Can make the difference between getting close enough or not for a shot.  In combination with the Sigma 150-600 it makes it a f/9 at 600 mm. In sufficient light and with good contrast autofocus still works on the Nikon D750 with the teleconverter attached.  ★ ★ ★ ★
