>>3524009>is A7R II/III/IV 'aps c mode' equivalent to using a longer focal length lens due to crop?Cropping makes the field of view equivalent, yes. Same as if you'd do it in post.
Really, whether you have an actual sensor 3/4 as large or do a centered crop to 3/4 in post, the outer 1/4 is gone. Pretty simple stuff.
> or is "crop mode" a shitty sony meme and bullshit?It is not just a Sony thing. Neither is the retarded "Super 35mm" naming.
