I have traveled to India a few times with minimal lenses.
Of all countries I have visited, India is probably giving the widest opportunity for interesting and colorful photos.
Sometimes with a wider zoom, sometimes with fixed focal , both with Pentax ist ds and Pentax MX 35mm film.
Although my little zoom goes to 70mm, I notice, almost never use higher than 50mm.
I prefer film camera these days but if traveling with aps-c and one fixed focal, -a small f/2.8 28 mm and a hood.
- covers 90% of cases daylight and evening.
How are you going to frame photos outdoors with the K-01 ? - mine is useless in sunlight.
Photo below is from a Pentax MX (35mm film) with the Rikenon XR 1:3.5 28mm
