Tamron SP 15-30mm f/2.8 Di VC USD

This is by far the best and most useful lens I've ever owned. Using this lens on a crop body give you a focal length from 23-45mm which is awesome for mostly everything. Doing a city trip I use this lens all day long, bright or dark - doesn't really matter to this lens. Usually during the day I drop down to f/5.6 and leave it there til sunset. Then I turn it to f/3.2 and continue.

Nikon AF-S Nikkor 55-200mm f/4-5.6G ED VR II

Small, lightweight and sharp. In rare cases that the 15-30mm get's exchanged for this lens - for obvious reasons. Years ago I owned a 55-300mm (the good one) which due to lack of common sense I sold. The 55-200mm only ads 300g to my backpack so it was the right choice for me. This and the 15-30mm are all the lenses someone would need for every day hobby photographing. Anything else is just for specific use!

Sigma 150-600mm f/5-6.3  C

A great telephoto lens, which only ways a little bit more than 4 pounds (2 kg). It´s great for shooting all kinds of animals as long as there´s enough light. Otherwise you have to rise the ISO. Well it has not the best performance out there but the only other option would be a Nikon AF-S 600mm f/4 for more than 10k€ for professional use. But hey, you can get sharp clear images so you can´t go wrong with this lens. 

Tamron 90mm f/2.8 Macro 1:1 Di SP

This true 1:1 macro lens is a great piece of glass. With a close focusing distance of only 30cm you are able to shoot tiny animals which fill the whole frame. It´s also a great portrait lens with its 9 blades it creates an astonishing background blur. Slap it on a mirrorless body and you get a vibration stabilization as well. Having less glass elements and weighing only 2/3 of the VC versions are specs I see an advantage. Regarding AF speed, for shooting macro it doesn’t really matter, I go manually most of the time. 

Nikon AF-S 18-105mm f/3.5-5.6G ED VR

The “standard” kit lens that nearly everyone at least had once. It has a beautiful crappy cheap plastic mount!! Yet, the glass isn´t that bad for such a cheap lens if you shoot in the “A”or “M”-mode you can get pretty good images. So let´s give it a chance. And for a short city trip the focal length is great and the lens is small and light. - until you get a hold of the 15-30mm.   

Nikon AF-S 50mm f/1.8G

I liked the AF-D version the most. Unfortunately, I changed it to this version, with one eye looking towards the mirrorless world which doesn't support mechanical AF. I even as far as claiming the old version was sharper.
