Let me fix that for you
Doesn't change much about the conclusion, though. Yep, insanely expensive, even though it comes with a free TC...
- Pany 200 f2.8: 8,75 x 17.4 cm, 1245g, $3000
Canon 200 f2.8: 8.38 x 13.72 cm, 765g, $750
- Canon 400 f5.6: 9 x 25.6 cm, 1250g, $1250
The Oly 300mm f/4 is "just" 2500USD.
The Leica 100-400mm is pretty much the bargain alternative at 1800USD ( ... or 1300USD locally ... )
Seriously 3k$? That's 1k too much no matter how you look at this.
It's even more weird when considering the fairly reasonable costs for the new Leica zoom lenses (8-18mm, 12-60mm). The upcoming 50-200mm f/2.8-4 is probably also in the same ballpark as those.
