Both builds use the Sony FE 16-35mm f/2.8 GM II so you can pin one and flip the body in the simulator.
| Sony a1 | Sony a7R V | |
|---|---|---|
| Sensor size | 35.9 × 24 mm | 35.7 × 23.8 mm |
| Crop factor | 1× | 1.01× |

Because the a1 has the larger sensor, the same focal length reads wider on it. Here's the full-frame-equivalent and horizontal field of view for each at common focal lengths.
| Lens focal | a1 (1×) | a7R V (1.01×) |
|---|---|---|
| 16mm | 16mm · 96.6° | 16mm · 96.3° |
| 24mm | 24mm · 73.6° | 24mm · 73.3° |
| 35mm | 35mm · 54.3° | 35mm · 54° |
| 50mm | 50mm · 39.5° | 51mm · 39.3° |
| 85mm | 85mm · 23.8° | 86mm · 23.7° |
What's the crop-factor difference between the a1 and the a7R V?
The a1 is 1× and the a7R V is 1.01×. The a1 is wider — with the same lens it captures roughly 1% more horizontal field of view than the a7R V.
Do the a1 and a7R V use the same lenses?
Yes — both are E mount, so any lens (or adapter) works identically on either.
Which is wider, the a1 or the a7R V?
The a1. Its larger sensor (1× vs 1.01×) sees a wider field of view from any given focal length.
