Autofocus

A lens that I got together with my used Nikon D750 body, and a great addition to the arsenal. Even better than the old one I have, and that's already a stellar lens.

I bought this lens for very little money though the local classifieds, and I'm happy that it wasn't too expensive, because it's a really lousy lens! 400mm and f/5.6 for little money might sound like a sweet deal, but it's a small and optically subpar lens with a pretty coarse mechanical construction. It has trouble conveying the right aperture information to the camera (says it f/7.2 all the time), and doesn't really excell in any field - brightness, AF or sharpness.

A highly praised lens, which I wanted from the day the price was announced. At 800.- USD it's very reasonably priced considering how bright it is, how well constructed it is and how sharp it is. The lens is on par with the best primes, and will most likely replace a handful of my prime and standard zoom lenses.

A really excellent telezoom that I bought used in the US for only 330.- USD. Built like a tank, great mechanical construction and really, really fine optical quality. The AF is not impressing since the lens is dependent on an in-body AF-motor, but it does the job. A very fine lens that I used a lot.

The so called beer can lens from Minolta, a really excellent midrange zoom with a stunning optical quality and a very good mechanical ditto

The workhorse! A bright, sharp, sturdy standard zoom that simply does the job and gets the picture. Not cheap and not lightweight or small, but definitely a must have for the serious DX body owner.

A killer lens and my new goto macro, releasing the outdated Sigma 90mm of its long and faithful duty. Great working distance, excellent handling and really, really good macro capabilities. This lens is tack sharp, has fast AF, sufficient brightness for my use (I use a tripod and/or flash for 95% of my macro shots). I don't use the VR function at all.

A classic portrait lens and excellent value for the money, but a little longer than a conventional portrait lens when mounted on a DX body

A fisheye is a great supplement to any lens lineup, and for Nikon DX owners this is the ticket. It's not cheap, but not extremely expensive either, and the quality of the mechanics as well as the resulting images are top notch.
