One of the biggest criticisms of early Sony mirrorless cameras was the fact the NP-FW50 battery did not have enough capacity for professional wedding photographers and videographers. I remember the early days when we filmed weddings using the Sony A6300 & A6500's. We would literally carry a bag full of NP-FW50 batteries and constantly be stressing over which camera needed to have a new battery soon.

For some projectors, it is possible to find the model name and serial number in the menu by following the steps below. This is especially helpful if the projector's model name and serial number label is unreadable or not accessible. The final sequence of letters and numbers (e.g. WD756, XE9405 or AF9) conveys a certain production series, which is important for support and repair purposes. It has been confirmed that when attached and used with the camera, counterfeit batteries can lead to issues such as:

As I have mentioned though, our desire for longer battery life outweighs the extra cost we need to spend on the Sony batteries. Yes it means we have to pay a bit more but the extra latitude that affords us is worth it in our opinion. My wife has already said she won't be using the Powerextra's for that reason. We'd much rather just pay more and have longer battery life. Having grown up in Yorkshire, I always have the urge to save money! Sometimes I have to remind myself of the adage, "Buy Cheap, Buy Twice!" and "You get what you pay for."I think it is clear that the original Sony battery is without a doubt superior. Which is as it should be given it does cost 2x more than the Powerextra. Over the course of a wedding day, videographers would need to carry less batteries, charge less and swap less if using genuine Sony batteries.

The Powerextra batteries perform adequately. But is 'OK' good enough for you when you are working in a high pressure environment such as a wedding? Cameras – LCD screen is heavily worn either by de-lamination or has scratches to it. Rubber grips are starting to come away from the body.

What's the difference between a model name and a serial number?

Using the Powerextra, I would clearly have to swap batteries earlier. I'd be nervously looking at the meter and fretting during groups and couples portraits about the remaining capacity. It is probably easier for us wedding photographers to swap out batteries. With a new battery, I could usually eek out a Sony NP-FZ100 battery until just before first dance. Where i'd probably be hovering around 6-7%. That would probably see me through the first dance until I left if I wanted to really push it. But is too close for comfort for me at a real wedding. So I have gotten used to putting in a fresh battery during the wedding breakfast when everyone is eating. It just saves me time later in the day and removes the risk of me getting caught out when I'm trying to capture the perfect moment between the bride and groom! For a full day of filming, we used to average out at going through three NP-FZ100's per Sony A7iii. With 25% less power per battery, we'd have to now use 4 batteries. An extra change on paper. But the shorter the battery life is, the more I would be stressing about the time to change.
