>>3282131There are a number of things holding me back from the Sony full frame mirrorless system.
>average size of lenses and the small grip compared to the lenses looks like really bad ergonomicsIt looks like with how shallow the grip is and how close it is to the lens mount, with one of the fatter lenses mounted, there won't be enough space for my fingers. With how big most of the lenses are, it seems like it would be hard to count on holding this camera with just one hand.
>cost of buying inThe $1999 price point of the a7iii body is attractive, especially for the feature set. That is a great price, and I expect the a7riii to follow. The a7rii is already down to $1999 to match the a7iii. However, the nice lenses are still more expensive than equivalent Canon L lenses, especially given the huge used market for Canon L glass compared to the relatively new Sony lenses, and the Canon lenses are a known quantity whereas I hear complaints about Sony sample variation pretty often. Nikon lenses are also less expensive and more available used, on average, than Sony lenses, although they also suffer from pretty bad sample variation.
>no top LCD The Fujifilm X-H1 and Panasonic G9 have proved that there's plenty of space on top of a mirrorless camera for one. Without an aperture ring or analog dials, like Fuji uses on most of their cameras, it's necessary to power on the rear LCD or look in the viewfinder to check your settings.
>seemingly not enough dedicated customizable buttons, and no front-of-camera function buttonsThere are certain things I need to be able to change without a menu dive, and I wonder if there are enough assignable spots on the camera. It will depend on the list of possible assignable functions, which I haven't been able to find.
Fortunately, the cost of buying into full frame is lower than ever. You can get a used Canon 5DII or 6D for well under a grand, and Nikon's high megapixel D800E is also coming down into the $1000 used price point.
