A bit more than two years ago I bought a Sigma 150-600mm F5-6.3 Contemporary, to use it to photograph birds with my camera at the time, the SD1 Merrill. In hindsight that was too much lens and too much reach for an inexperienced bird photographer such as me. What followed was a longer break from photography. For a long time I didn’t take photos at all. And now I’m in a situation similar to back then: the cold time of the year is over, days are already long and getting longer still and animals show their faces with increasing frequency. It is the perfect time to get a long telephoto lens and start practicing. 🙂
That was my train of thought at the time the mouse cursor was hovering over the order button. My Sigma 100-400mm F5-6.3 Contemporary is already here and I have taken it with me to a couple of photo walks. Even after two years one immediately notices the missing 800g and 8 cm and 2 cm shorter length and width respectively compared to the 150-600mm C. You can carry the 100-400mm for much longer, before your arms start feeling heavy.
There is a „catch“, however: you have to get a lot closer to the birds than with the 150-600mm, which isn’t possible a lot of times. You can’t have everything. 😉
