JJC 2-Pack Eyecup Eye Cup for Sony A6700 (Replaces FDA-EP20)
Quick take
This JJC eyecup replaces the Sony FDA-EP20 and is designed for the Sony A6700, using soft silicone for comfort and a snug fit for steadier viewfinder use. It rotates 360 degrees so you can align it for your left or right eye, and it adds protection against impact and scratches. The main catch is eye relief, which may be less friendly for glasses wearers.
Pros and cons
Pros
- Snug, secure mounting that reviewers say does not wiggle or pop off easily
- Soft silicone eyecup material that can feel more comfortable for pressing to the viewfinder
- 360-degree rotatable design to suit left-eye or right-eye shooting
- 2-pack value for a spare or replacement, with added viewfinder protection
Cons
- Glasses may make the viewfinder less usable for some, due to how the eyecup changes the viewing position
- Even with a solid fit, the eyecup design can partly block nearby sensors depending on alignment
What buyers think
Buyer feedback is strongly centered on fit and comfort. Multiple reviewers describe the eyecup as installing in seconds and fitting securely, with less looseness and fewer pop-off issues compared with the stock eyecup they were replacing. Comfort is also a common theme, since the soft silicone makes it easier to seal your eye to the viewfinder during shooting.
Another repeated theme is alignment flexibility. The 360-degree rotation is viewed as practical, especially for adjusting the eyecup direction to match the way you shoot. Overall, review evidence supports that it is a straightforward, durable-feeling accessory for people not using glasses, while glasses wearers should pay extra attention to eye relief and framing.
What it is and why you might want it
The JJC eyecup is a small viewfinder accessory intended to replace the Sony FDA-EP20 eyecup on the Sony A6700. Its job is twofold: improve how comfortable and stable it feels when you press your eye to the viewfinder, and help protect the viewfinder area from everyday knocks and scratches.
It also aims to reduce common shooting annoyances tied to eye alignment. A properly positioned eyecup helps you maintain a consistent viewing position, which can matter for long sessions, bright outdoor shooting, and anyone who frequently switches between left and right eye use.
Key features that affect real-world use
Soft silicone comfort, solid mounting
Built with soft silicone for the contact area and supported by a more rigid ABS component, the eyecup is designed to mount easily and securely to the viewfinder. Reviewers frequently mention a snug fit with little to no wiggle, and that removal takes deliberate effort, which is a good sign for resisting accidental bumps.
360-degree rotation for left-eye or right-eye shooting
The eyecup can rotate through 360 degrees, so you can adjust the direction to fit your preferred eye. If you alternate eyes or want the eyecup to sit naturally with your shooting posture, this feature can reduce time spent readjusting your face position.
Viewfinder protection and scratch resistance
Because it’s positioned on the viewfinder, the eyecup acts as a barrier against minor impacts and scratches. This is especially relevant if you travel, shoot in crowded environments, or regularly handle the camera in and out of a bag.
2-pack value
You get two eyecups, which can be helpful if you want a backup for the future, plan to keep a spare in your kit, or simply prefer having a replacement on hand.
Pros and cons (buyer-fit first)
Who it’s best for
- Sony A6700 owners who want a comfortable, secure eyecup replacement
- Photographers who switch between left and right-eye use and benefit from rotation
- Anyone seeking an inexpensive way to add minor viewfinder protection
Who should consider alternatives
- Glasses wearers who are sensitive to eye relief changes, since some reports indicate the eyecup can affect viewfinder framing
- Buyers who want a solution that is guaranteed to preserve an unobstructed view while wearing glasses, since real compatibility may vary by eyewear and face geometry
Installation and compatibility notes
Installation is described as quick by reviewers, suggesting the eyecup snaps into place easily. It is intended as a replacement for the Sony FDA-EP20 on the Sony A6700. As with any eyecup replacement, your results can depend on how it sits on your specific setup, including the way your eye contacts the cup and how close your face is to the viewfinder.
One review mentions that a nearby sensor area can be partly covered, though the viewfinder still functions normally for that user and screen obstruction was not reported. That said, if you’re particularly sensitive to how accessories interact with viewfinder-adjacent components, it’s worth checking that nothing essential is blocked after installation.
Verdict
If you’re looking for an affordable eyecup upgrade for your Sony A6700, the JJC 2-pack is a strong fit for buyers who prioritize comfort, secure mounting, and rotation for left/right-eye use. The main reason not to buy is glasses compatibility, where some people may experience reduced visibility due to eye relief changes. If you do not wear glasses (or your eyeglasses don’t interfere with the viewfinder edges), this is a practical, low-fuss accessory to improve everyday viewfinder comfort and protection.
