I currently have the 200-500 f5.6 but feel that I am often needing to increase the ISO up to 3200 and even 6400 to get a fast enough shutter speed of say 1/1600 etc, when its a cloudy day or the light drops.
In bright sunny weather (not often in the UK) the lens performs very well, but as soon as the light dips the ISO needs to go up!!!!
I would appreciate some feedback on what lens you think would give better results than below.
I wondered in the 300mm F4 PF VR would give me better results although I know if I put the 1.4 converter on it it will take me to f5.6, but at 300mm its f4 which I guess gives me an extra stop so I could use ISO 3200 instead of 6400?
The last shot of the tiger is not an image I would keep but its just to illustrate that when I need to crank up the ISO the detail is lost, particularly if you view the snout of the tiger at 100%.
