GEAR

Photography gear and travel items that I actually use and find helpful.

RICOH GR IV Accessories

I have put together a list of the accessories I bought and actually use with my RICOH GR IV.

The article covers practical items for protecting the camera and carrying it comfortably every day, including a screen protector, lens filter, metal lens cap, hand strap, microSD card, portable charger, and camera pouch.

Best microSD Card for the RICOH GR IV

I wrote a separate guide about why I chose a 128GB UHS-I U3/V30 microSD card for the RICOH GR IV.

The article explains the card type, capacity, UHS-I support, U3/V30 speed class, and why reliability matters more than buying the cheapest card.

Camera Pouch for the RICOH GR IV

I found a compact camera pouch setup that works especially well with the RICOH GR IV.

The article explains why I attach a lightweight neck strap to the pouch rather than directly to the camera, how the GR IV fits inside, and why the horizontal layout makes the camera easy to carry and quick to access for street photography.

JJC Protective Wrap for the RICOH GR IV

I reviewed a lightweight JJC protective wrap that makes it easy to carry the RICOH GR IV casually in a bag without adding much bulk.

The article shows how the wrap folds around the camera, explains how its soft inner surface helps prevent scratches, and compares its role with a dedicated camera pouch.

A visual guitar learning tool I built with AI to practice the pentatonic scale from fretboard shapes.
