First, please let me apologize for my lack of proper vocabulary. 😃
I have a Canon EOS R50 with the stock 18 to 45 lens.
I need a stronger telephoto capability, to take bird pictures, the moon, get that lone oak tree out in a field etc. There are devices that one can place between the lens and the body to <<telephoto more>>, right? Would it be better to get one of these or to buy another whole lens? I am assuming the adapter would be less expensive. Money is a factor. (isn’t it always?)
I stopped in at my local camera store and an ef to rf adapter would only be $130, it goes on the Christmas list. I was able to try it out with my Dad’s lens and autofocus seems to work fine - I was not sure how to test to see if aperture control was working but It probably was.
A lens made for my R50 would cost much more $300.
