Hello UHH folks. Have a question for anyone. I am traveling to South Africa this coming December for 10 days.
I am taking my 7D MK II, my 5D MK IV, my 100-400, 24-105, and my 16-35. (in country flying only allows you a total of 44 lbs so my Guru Gear backpacks will be just filled with essentials.) My question is this: I am renting the r7 and the adapter (RF/EF) to try out...but I have been told that if I use the 100-400 with a 1.4 xtender with the r7 that the images may not be as good as if I just use my 7D MK IV. I wanted to try out the r7 mainly due to its fast auto focus and upgraded MP's. Wondering of any UHH folks have either encountered or have heard of any image issues? Thanks for reading.

If you are evaluating a camera or a lens concerning its imaging abilities, you do NOT add anything else optical to the package.

To evaluate a cameras imaging quality you use a good lens at its ideal aperture. To evaluate a lens you use a mid to high rez camera at base ISO.

These are NOT things to do on the road. So forget renting anything to evaluate it. Bring your familiar gear and use it for its normally intended purpose.

Or, you could adhere to UHH Sacred Tradition and ignore the above advice. Plenty of happy followers of UHHST seem to have a grand old time messing up and then crying to the clown car for help. If thaz what rocks your boat then youre certainly not alone in that. Youve asked about gear that doesnt even exist, so youre off to a good start with UHHST. Enjoy !

The digital sensor knows nothing. A mirrorless sensor don't know an EF lens is attached via an extender. Given a mirrorless sensor uses different and better AF technology, all results of an adapted EF lens should be superior to the same lens on an DSLRosaur, at the minimum, exactly the same as when used on a DSLR. Consider the source of your "I've been told" information vs the mustard colored pages of UHH. Or, just look at the results with your eyes, given the travel is not until December.

The lens makes the image.
The camera just records it.

If you believe that and it works for you, run with it. But youre not preaching solid facts, just a tidy typical UHH slogan.

I see that same world from the other end of your cardboard tube and I get a reverse tidy slogan: "The lens just focuses the light. The camera actually creates the image."

Acoarst neither of those two tidy slogans is uniquely factual. At best, they are very tidy. Each is supportable but neither is wholistic.

Of course it's not so simple. The camera and the lens work together. You don't get a photo unless you have both of them. But they are both important, it's just that their importance is relative to different things.

Same camera body, great lens;
Same camera body, poor lens;
What makes the difference in quality, not the body.
Change the body AND the lens- now there are two variables involved.
Keep the body constant, it's the lens.

You will be losing more from not using a tripod, a good lens shade, and a cable release than from equipment quality

Now there are five variables involved.

Any more?

Filters?

Yeah...

How healthy you are...

Trembling hands?
Poor vision?
Color-blind?

The main questions I have are:
- Unless you are a pro, why so much gear?
- This also implies if a pro, why ask this question in a forum?
- This in turn begs the question, what is your experience as a traveler?
