EOS R, EF-S Lens Crop Loss of Megapixels

[mindawoo]

I currently using a t2i Canon 18 mp crop sensor camera, According to Canon, when EF-S lenses are used on the EOS R camera the camera "will automatically produce cropped 11.6-megapixel images that match the smaller image circle of EF-S optics." So a 30mp camera effectively is now 11.6mp, much less than what I have with my current set up. I am looking to move to full frame so the EOS R seemed to be the way to go until I hit this stumbling block. I can't afford to buy both the camera and new lenses at the same time but plan to upgrade lenses slowly as budget permits. Is this something I should be concerned about or will having a better sensor and newer technologies make up for the loss in megapixels?

@ebiggs1 That`s a fact 👍😂

Dear @Waddizzle

I know that aperture values have nothing to do with the type of lens mount 😂

I was referring to the fact that the circuits of teleconverters (or speedboosters) act like a middle man, so the camera couldn't identify whether the lens attached is an ef lens or ef-s lens.

There is no middle man in an extension tube or in a reverse mount adapters, hence the camera will identify whether the lens attached is an ef lens or ef-s lens. 😉



i'm afraid a lens like 50mm won't be as good as a wider lens like 18mm in lens reverse situation.
I'll show you some results.

this is the maximum magnification of a canon 100mm macro lens (Not Reversed 1:1 magnification)

this is 50mm f/1.8 Full frame lens reversed ( wich was your sujestion)

this is 18-55mm EF-S lens reversed @18mm

so, imagine the result of 10-18mm EF-S lens reversed @ 10mm
🤣🤣🤣😁😅
