The Sony FE 85mm f/1.8 is an excellent choice for interviews. Great bokeh, sharp, and the focal length is perfect for a natural perspective while maintaining comfortable distance from your subject. Much more affordable than the GM version too.

^ This. Also, I totally agree with M_89s about the 85mm. I remember my first big corporate gig, I was so nervous about gear failing that I almost blew my whole budget on a GM lens I couldnt really afford. Tbh, I ended up getting the Sony FE 85mm f/1.8 instead and its been my absolute workhorse ever since. It just works every single time, no complaints. I prefer sticking to a few reliable primes because they have fewer moving parts to break during a long day of shooting. Staying satisfied with a simpler setup has saved me thousands over the years.

• The Sony FE 85mm f/1.8 is basically a steal for how sharp it is. Its never let me down on an interview.
• If you need a second angle, I highly recommend the Sony FE 35mm f/1.8. Its small, light, and incredibly reliable for wider shots.
• Pro tip: Look for used copies at places like MPB or KEH. I saved a few hundred bucks on my 35mm by buying used and the quality is identical to new. Going the budget-friendly route doesnt mean you're losing out on quality, plus you get that peace of mind knowing your gear is solid.

For shooting interviews with a Sony camera, I would recommend one of the following lenses:

1. Sony FE 24-70mm f/2.8 GM II

• Very versatile focal range covering wide to short tele
• Fast f/2.8 constant aperture for low light and shallow depth of field
• Extremely sharp optics
• Built-in optical stabilization

2. Sony FE 85mm f/1.4 GM

• Ideal focal length for flattering portraits and interviews
• Extremely fast f/1.4 aperture for creamy bokeh and subject separation
• Razor sharp even wide open
• Focuses quickly and accurately

3. Sony FE 50mm f/1.8

• Affordable option that delivers great image quality
• Bright f/1.8 aperture performs well in low light
• Compact and lightweight
• Fast and silent autofocus

I use the new released FE 20-70mm f/4 G lens on my a7C II, a compact and lightweight lens. Works well.
