Extenders R5 with 100-500R+1.4x

[LaurieAndersonPhotography]

Is anyone using this setup? Just wondering how well the 100-500Rf performs with the 1.4x.

Nice sharp images, fast AF and as long as you are prepared to lose reach at the short end it's not a problem.

Ok yeah losing reach is no issue

I have used the 1.4 several times and been very happy with it. Of course F10 requires higher ISO to keep shutter speeds up. I often use Auto ISO and cap it at 12,800 and use Topaz DeNoise AI to clean up if necessary. Here is a sample.

Looks great! Wow!

I really appreciate the light weight and portability of this lens and R5 combination. The IQ is superb and the files leave a huge opportunity to crop.This shot is taken at about 6-7m distance and it's a small bird so you can easily crop to 100%. However, the more you crop the more you will see noise appearing even at fairly low ISO values of around 3200. I have found Topaz does an admirable job at cleaning up this really fine noise but I don't want to stray in to high values because removing noise comes at the cost of removing detail from my experience. With the lens fully extended you are shooting at f10 so good light is a big bonus. At f10 you find the background bokeh might not be a pleasing as it might otherwise be but if you are lucky enough to have a degree of background separation then it's not a problem. Wildlife doesn't perform on command but choosing your spot to shoot from helps improve the chances!
For the record, this shot is ISO 2000, 1/2000th f10. No PP whatsoever, just reduction in file size for posting!

Here's an example that is not out to 700mm. I was using our guide's R5 with the 100-500 and 1.4. After 10 minutes of shooting with this combo, I knew I was changing systems.

Wow! I know I’m gonna need to get that lens!

What would you say is the weight difference from a DSLR with the 100-400mm+1.4x as compared to the R5 with the 100-500mmR +1.4x?

It's not huge but it's noticeable. Both are lightweight compared to my 500mm f4 Mk2 and 1.4TC combination. The 100-400 of course doesn't match the reach of the other two and if that is important the 100-500 is a better choice over the 100-400.
