Switching systems

I've been with Nikon for about 20 years. I started with a D50 and the 18-55 f/3.5-5.6 kit lens plus a 50mm prime. Not long after came a Tamron 70-300 f/5.6-6.3. Then an upgrade to a D80. A new kit lens 18-135 f/3.5-5.6, then an 85 f/1.8 to go with the 50 f/1.8 I already had. And an 80-200 f/2.8 as a tele. The next step was full-frame — a Nikon Df. I decided to stick to primes only: 35 f/2, 50 f/1.4 and 85 f/1.4. Over time it became clear that I'd need to move on. The autofocus point coverage on the Df wasn't ideal — too few cross-type points. Mirrorless was an inevitable step. But Nikon doesn't allow third-party manufacturers to produce lenses for the Nikon Z mount. Which means you're stuck with a single manufacturer. No competition, no pressure. Historically I shot a lot on Sigma and Tamron — for the price, rendering, and value for money. I simply wanted to keep that option open.

So after twenty years I sold my kit. I'm moving to Sony. I believe the possibilities offered by Sony Alpha and the Sony E mount are better than what Nikon currently offers with its Z mount.
