Sony FX3 Full-Frame Cinema Camera
I do not like to charge in-camera, and being angry with Sony for shorting the charger with my new A7-IV I figured they didn't deserve any more of my money. I bought a Wasabi set consisting of 2 batteries and a USB charger which gave me three batteries, one Sony and two Wasabi. Subsequently, I purchased a used A7R-III as a backup that came with two Sony batteries. This brought me up to five in total. Since that time I have shot thousands and thousands of photos using both Sony and Wasabi. My conclusion is that there isn't any difference in practical use, or if there is it's so minimal it isn't worth worrying over.
There is no difference in charge time between the two
Any difference in the number of shots is negligible, I've never even noticed it
The cameras don't care which battery is installed, no warning messages
The cameras' meters are accurate and scale the same using both
To be honest I didn't expect anything different having used Wasabi extensively in other cameras. While I'm sure posts about Sony cameras showing a warning message with aftermarket batteries are accurate, it doesn't seem to exist with either the A7-IV or A7R-III. Other concerns about the battery meter not scaling properly with aftermarket units haven't materialized either. For the difference in cost, about $250 versus $50, it's a no brainer.
Used before and used many other brands for my Canon and now Sony A7 Series cameras. Brand has been here, always rated high on tests and much less expensive than Sony. Sill use Sony but these are the backups I have and rotate with my Sony's. Very happy with Wasabi!
Sony NP-FZ100 Battery by Wasabi Power
I received the item within a few days and it is working fine to power my camera fo a long interval time lapse. Much better than changing batteries every 3-4 hours.
The price is good but the quality is just ok. The capacity of the Sony battery is better and there is no warning notification on the camera when using the Sony. Shipping was fast.
