Re: EF300mm f/4L IS USM with Teleconverter on Crop Sensor?

I am using the 70-200 mm with the 2x extender and I’m getting good results. That gives me f5.6.

But I need to stay on high ISO, like 2000 to get very good bird shots at 1/2000 speed. Since my camera is a bit older, I use DeNoise AI and Sharpen AI to get super results. With IS, you should be able to lower a bit the speed or ISO but birds in flight require some speed nonetheless.

I assume that you have checked compatibility for the lens with the extender as this is not automatically compatible.

Regards,
There is always something to shoot/snap, you just have to know how to do it and have the right gear.
