Re: For about the same price..RF 70-200mm F/4 or EF 70-200mm 2.8 IS iii ?

I'm exactly at the same point!

I have EF 70-200 2.8 III. This is a really great lens!

But, I began to look on the RF 70-200 f/4.

Main reason - weight and size. Looks like a big difference.

Second reason, I think EF lenses will decline eventually and it is better to sell them when they worth the most.

Regarding the F - I was surprised how there is a little difference between f/2.8 image and f/4 image bokeh. sometimes barely noticable and even then only in comparison.

The hurting point is not the bokeh actually, but the speed or noise. If I switch from f/2.8 to f/4, I have either to slow shutter twice, or to raise ISO twice. Now if you shoot action or sport, you can't lower the shutter, so you raise the ISO, eventually getting more noisier images. Now noise doesn't scare me that much. But if I have the option to have it less...

So This is really 50/50 question for me.

For now, while I'm thinking about it, I'm staing with the EF 2.8
