EOS R5 Mark II Crop Censor Setting & Question About Exchanging EF 100-400 L For RF 100-500mm

[Far-Out-Dude]

I was wondering if anybody could tell me how I should set the crop in camera (R5 Mark ii) for the following lenses?

Canon EF 100-400mm f/4.5-5.6L IS II USM Lens

Canon EF-S 18 55 macro 0.25m 0.8ft

Oh I guess the Canon EF 70-300mm f/4-5.6 IS II USM as well please.

I also am thinking about exchanging my Canon EF 100-400mm f/4.5-5.6L IS II USM Lens for the Canon RF 100-500mm f/4.5-7.1 L IS USM Lens, I was wondering how the lenses compare? Thank you for your time.

Hi!  I hope you are doing OK.

If you mean how do your put the R5II into crop mode,  In the red section of the menu, On the first page:

Check out the Advance User Guide: P`169:  c017.pdf

Note this is simply cropping the image that will be recorded, it's effect is precisely the same as if it was cropped in post processing mode with a resultant reduction in MPs capacity.  The main benefit of this is to allow you to crop as you shoot by reducing the Field of View.

I have frequently posted an article on Equivalence: how sensor size changes the field of view and other characteristic.  I enclose the link to the article for your convenience:
Equivalence 

As regards the following lenses:
EF-S 18-55 is not really a macro lens and as a kit lens designed for APS-C sensors, would be a good candidate to consider replacing with a FF RF lens, such as one of the 24-105 variants.  That would work well with either the EF 100-400 or RF 100-500 lenses to give you an unbroken focal range from wide to super telephoto.

The EF100-400II is an excellent lens and will work absolutely fine with the R5II either in crop or FF modes: you just need one of the EF-RF Canon adapters.

The RF 100-500L is also a fabulous optic and of course is specifically designed for the R systems. Apart from the extra 100mm of reach, it also has dual nano-USM motors that make its focusing blazing fast and should be slightly easier to gain and track focus.  Really, it depends on what you are going to shoot.

The EF 70-300 is a good lens and should work fine with the R5II - certainly, I would give it a go. Again, it has a nano-USM motor to make its focus fast.

As to exchanging the EF 100-400 for the RF 100-500, I did post several images in the Gallery > Share Your Photos section showing results from shooting wildlife with the EF100-400 and RF 100-500, and I also did a comparison of the RF 200-800, against the RF 100-500 in 1.6 crop mode to achieve the same FoV.

Thank you much for the reply. No bud, I am not doing well at all to be honest.

That is what I wanted to know, I was of the impression it would bring the view in tight but if it only crops and I can do the same in Lightroom I see no sense in doing that. I would like to get the Canon RF 100mm f/2.8 L Macro IS USM Lens eventually, I have talked myself out of macro lenses for a long time because it is hard for me to get to the ground and back up due to my injuries but now I will just try to get one. I just have to try to get a landscape lens first which is what I have been using the EF-S 18-55 for landscape as well as other lenses for the M50

I am truly sorry that things are not going well for you.  You have my deepest sympathy, my friend.

The term 'macro' can have a lot of interpretations.  True Macro means that the image on the sensor is physically the same size as the original object, so that ANY magnification will make that image larger than life.  Now, you can get lesser effects without going for a full Macro lens - as these tend to be fixed focal length lenses.

Even the RF 24-104 f/4 lens will do amazing close-up work and, as I suggested, would make a great replacement for the EF-S18-55 that is designed for crop sensor bodies.  I took this image of a tiny circuit board being created by scientists who were working with microscopes.

It's versatility also includes panoramas, and portraits:

I thank you bud, I have not even left the house with the new camera I have been so depress, all I do is sleep and take the dog outside a few times a week.

Thank you but I have not had very good luck with anything I have ever purchased that was refurbished/renewed and besides that it is just $139.00 USD more to get a brand new one with a 4 year warranty.

No problem mate.  There is always a period of intense grieving when one loses someone intimately close.  I would encourage you to make the effort to go out and really look for a good photograph each day: the process of finding a great image puts one 'in the moment' and takes us away from the dark thoughts that can dominate us, because we are looking at the world through that viewfinder and concentrating on something outside ourselves.  The dog will thank you for the daily walk too.

Definitely the new lens seems like the better deal for you.  If you can afford it, then make that a trigger to take the camera out and learn about its capabilities with the lens.

When using the Canon adapter the crop for EF-S lenses will be applied automatically by the camera. There is no crop required for Canon EF lenses.

I am using the Canon Control Ring Mount Adapter EF-EOS R adapter for the EF and EF-S lenses.
