RF 100-400 plus 2x extender

Hi folks
I’m expecting the 100-400 to be delivered tomorrow, and am excited to try it out. I also have an 800 f11, just am considering rationalising past swapping information technology for a 2x extender. But I cannot aford to purchase a 2x extender just to try it out, So if anyone has the combo, would you endeavor it and let us know how it works delight. Particularly if yous arr able to compare with the 800 f11. Thank you.

You do realize that the 100-400 with 2x volition requite you an constructive discontinuity of f/11 to f/sixteen.  Not sure I’d fifty-fifty want to endeavour that.

You lot do realize that the 100-400 with 2x will requite you lot an effective aperture of f/xi to f/16. Not sure I’d even desire to endeavor that.

The 800 f11 but has an f11 aperture, and is excellent. I used it in concert without flash on Saturday evening; there was noise, merely a very quick click on LR sorted it out. So in principle I’m non overly worried.

The RF 600 and RF 800 are f11 and the results are pretty astonishing all things considered.

I don’t incertitude the 800 on its ain is very practiced. Simply yous’re talking nearly putting a 2x extender on a budget zoom lens. I didn’t like the IQ of the gen one 100-400 Fifty with a i.4x II.  If it were me I’d rent the combo offset.

I doubt the zoom with a 2x converter volition be equally good every bit the RF 800 F11. B&H only shows the ane.4x converter in its accessory list for the RF 100-400 and that would be a cherry-red flag for me. I accept the RF-800 F-11, RF-600 F -xi, RF-100-500mm and the RF 1.4x converter. All three lenses piece of work well with the 1.4x just I have never been very happy with my results when using a 2x converter so I passed on buying the RF one. One of my favorite long lens setups is my Sigma 150-600mm Sport with a Canon EF-1.4x III converter 840mm F-9.
