I've been thinking about getting an APS-C lens to put on my A7RII to shoot weddings.
The large raw files are overkill.
Just turning on APS-C framing means using existing lenses, 16-35, 24-70 and 70-200 in a different mix.
There are a couple of Zony APS-C lenses that look attractive as alternatives.
The 16-70 F4 would be very similar to the Canon 24-105 I loved. That focal range also covers about 90% of what I use for wedding coverage.
The added benefit, as I understand it, is that when mounting an APS-C lens the camera automatically switches to the smaller area. Then when putting a full frame lens on it automatically switches back. That would mean I could use the APS-C lens for most of the shooting and switch to an FE lens when needed for larger files.
Is it worth the effort?
