Wildlife and portrait camera suggestions

[g_khajanchi]

Greetings to everyone,

I have a RF mount lens and want to upgrade my camera, so suggest this...

Which camera should one buy for wildlife and portrait photography, R5 Mark II, R6 Mark II or R6 Mark III?

My budget is around $4500 (INR 4 lakhs).

First there isn’t an R6 Mark III. Only an R6 Mark II at this current time. What is the Full name of the RF Mount lens you have. Saying “RF 70-200mm” isn’t a complete name because multiple lenses have that name. The full name would for instance “RF 70-200mm F/4L IS USM” lens.

Means awaiting for upcoming R6 Mark III.

Available lens RF100-400mm f/5.6-8 IS USM & RF24-105mm f/2.8L IS USM

Do you need 45 megapixels. Is recording video something important to you. Or is it just an unused feature of camera. Do you only do stills work only or record video too. You need a computer that can handle a lot of data. 45 megapixels creates large file sizes. The R5 Mark II has limitations with older LP-E6 batteries. Such as first generation LP-E6 won’t even work in the camera. Then the newer LP-E6N and LP-E6NH have restrictions on recording video and drive mode for shooting. The newer LP-E6P was specifically designed for that camera. To make full use out of the camera the LP-E6P battery is required. I would get a couple extra batteries if you go with the R5 Mark II. Not any of the older LP-E6 series batteries.

Most use is for photography and storage is not a problem.

Are you going to be cropping the pictures if so the R5 Mark II would be a better choice.

[g_khajanchi]

Ok, if other model is best under my budget then suggest

The EOS R6 Mark II. Have you considered the EOS R7 too?

R7 is crop sensor so not look

Ok I didn’t that that you strictly wanted a Full Frame body. Or even might have owned a crop sensor R series camera.
