Just Another Lens

Did you buy another lens? Why do you need another one?”

I recently bought the Sigma 120-300mm F2.8 lens. Admittedly, this was a very though decision, as I have a lot of gear.  Why did I do this?

  • At many events my 400 was too long and the 70-200 was too short. Examples? Football when the play comes closer, athletics when athletes react after the finish line.
  • Moreover, I love the flexibility of a zoom to shoot the same scene close and wide at the same time. So a 300mm prime lens was no option (and far too expensive).
  • Finally, I needed a fast lens. F2.8 was a must.

There’s only one lens on the market that can do all this: the Sigma 120-300 F2.8

Critics on the lens were excellent. So I took the risk and bought it instead of renting it first.

I added a Sigma USB dock, because I understood that Sigma lenses almost always have either front or back focus problems. I downloaded the adjustment software and spent one very dull evening with the calibration of a heavy back focus problem (thanks Tobias Wagen for cheering me up via the facebook chat).

Moreover, the lens weighs more than 3kg. From my experience with my 400mm prime lens, I knew I could hold it for a while and use a monopod between the shots. I certainly would think twice if I had to carry it with me as a nature photographer (which I am not).

The next event on my schedule was the Swiss Volleyball Cup Final. So I took the lens with me to this event. My friend Stephan Wiesner came with me and prepared a video.

So what is my verdict?

It is a great lens. Some “testers” have complained about this or that… I don’t care!

  • The pictures are sharp. Period.
  • The autofocus is working. Period.

The only serious complaint is about the initial back focus problem. Sigma stole me 4 hours to fix it. But here’s the second thought. I saved about 3’000 stones compared to a 300mm prime lens. In this sense, buying the Sigma 120-300mm lens instead of the 300mm prime is like receiving a daily wage of 2 x 3’000= 6’000.

This makes me feel good! I should go and buy another lens!

*** UPDATE: One month later I had many more opportunities to work with the lens. I stick to my verdict, but with a slight qualification. When the action comes close and I am shooting at 120mm at a distance of, say, 5-7m, the autofocus has problems. I missed some shots at Bundesliga matches. ***

*** UPDATE 2: It’s the beginning of June and I had the first serious issues with the lens. I used it at two meetings in midday sunlight and the results were… BAD. I immediately switched back to my old equipment which worked nicely. As this happened twice I will do further tests. Was it the sunlight? Was it me? Do I have to repeat the calibration? I’ll let you know, but it will take some time. ***
