Unimaginable focal size of lens. I’ve the 600 F4 II. It is an awesome lens however its massive and heavy. I’ve handheld it however its not good for you.
I normally apply it to a strong tripod with a wimberly gimbal head which is one other few KG’s added to the load.
Getting a bag that match it was tough. Even when I may afford 800/1200 I would not think about it because of the logistic effort of transferring it round.
I typically use a 2 extender with the 600mm. It may be fairly tricking truly discover one thing you see with 1200mm. One piece of grass or a tree can look very very like one other at 1200mm. I feel I would discover an 800 or 1200 a really rigid lens.
There’s alot to be stated for a 100-500mm or a 200-600mm way more versatile and lighter.
Nonetheless there’s a marketplace for the final word. Perhaps it can include a free donkey to hold it on treks.
