I'm a casual & amateur street photographer.
OK, so recently I sold my entire Canon gear (6D and 24-105 + extras) and I switched to Sony for the first time ever. The main reason was to be ultra portable while still remain in a full frame world hence the choice. The only lens I bought was deliberately small Carl Zeiss 35mm 2.8. This combo is lightweight and I like it.
However while 35mm is classic for street I can forget about subject isolation due to the focal length. I fight hard to keep the background tidy but it's not that easy.
I would like to try something longer. Ideally 85, but I came up with a nasty idea. You already see the title.
Since A7III offers crop mode that I assigned to my C3 button, I can quickly turn it on or off. I know that the downside of crop is less megapixels due to the crop factor.
Question: would you rather go with Zeiss 55mm / 1.8 and enable crop to get something around ~85 on fly or would you directly go to Sony 85mm / 1.8?
Getting 55 and switching to crop on fly looks a way to get virtually 3rd lens for free. I know that 24 mega pixels will be reduced in the final image but this is still acceptable. What would you recommend?
