Just now I was looking at the metadata on photographs I took with my Nikon D500 and the Nikon 70-300mm VR AFP ED. It is a full-frame (FX) lens with an aperture of f/4.5 at the short end and f5.6 at the long end. The reason I was looking was to see what focal length ‘reach’ I would need to marry with a Canon EOS R6. The D500 is a crop-sensor camera whereas the Canon is full frame. So I need to multiply the crop by 1.5 to compare the Nikon focal length with the Canon.
I shot this first image at 300mm, which is equivalent to 450mm in full frame. And I shot the second image at 240mm, which is equivalent to 360mm in full frame.
Canon makes full frame RF mount lenses for cameras like my EOR R6. The company makes lenses that would cover the distances needed for these photos.
But look at the prices! £3,000 for a lens. I like the images that come out of the R6, but if I were starting again I am not sure I would allow the look of the images to trump everything else.
Perhaps I will need to look at EF lenses and a converter.
Or when will Sigma or one of the other third-party lens manufacturers be allowed in to the Canon ecosphere?
