Soon I will have to decide whether to stay with Sigma 100-300 f4 Apo DG EX + Sigma TC 1.4x or sell the combo and get the Px telephoto. Whatever I choose I will have to stay with the chosen lens for years so I dont wan't it to be a stupid decision...
I use Sigma for birding and general nature/landscape pohotos.
I regret Sigma is not weather sealed -- but there's no problem to get a sleeve for $15 or less.
It's noisy. Skittish pheasants in my neighbourhood run away just before I press the shutter.
I've discovered that cropping photos taken by my Sigma (on K3-II) gives slightly better results than use it with TC. So TC is useless now.
On the other hand it's f4.
I expect 150-450 to be faster to focus, flare resistant, quiet. But is the IQ much better than Sigma?
Do you happen to have both lenses and give me a piece of advice?
TIA
