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. 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. Each TV model name is more than just a random sequence of numbers/letters. The name contains model-specific information.

Lenses – The lens has dust inside that may affect images. The rubber zoom/focus ring is coming away from the barrel of the lens. Over the course of a wedding day, videographers would need to carry less batteries, charge less and swap less if using genuine Sony batteries.

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. 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.

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!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." 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. Some models have the IMEI number inside the memory card slot. Use your fingernail or an unfolded paper clip (or similar) to drag the label tray outwards. It has been confirmed that when attached and used with the camera, counterfeit batteries can lead to issues such as: The next step depends on the Android version of your phone.The path might differ on older Android versions.

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. 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. If the first letter in the final sequence of letters and numbers is an " A", then the TV is part of our OLED line-up (e.g. KD-48 A9S or XBR-65 A9F). 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. 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.

Accessories

Also, it has been confirmed that counterfeits with a decreased battery capacity compared to the genuine batteries are being distributed to the market. The use of counterfeit batteries implies a fire or explosion hazard. Lenses – Should have no marks on the elements andoptically clear. There may be light dust present that will not effect theimagery.

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? Ultimately I think what it boils down to is how much are you willing to spend to save swapping batteries? Clearly the Sony is the superior battery here. So if you want to have minimum battery changes, the least amount of batteries to charge before a wedding then your choice is clear. On the other hand, if you want to save money and don't mind changing batteries more often, then the Powerextra batteries might suit your needs and offer you value for money.Our used products are subject to wear and tear in comparison to brand new products. This also applies to accessories that are supplied with the camera including batteries which may have a lower optimum performance level/life expectancy. Battery life was massively improved when Sony released the A9 with the new NP-FZ100. Since then this has become the new battery for all modern Sony mirrorless cameras. The first part of the model name(before the hyphen) indicates the TV’s resolution: 2K (KDL) and 4K (KD). One option I just thought of is to use the original Sony battery you got with the camera and have one PowerExtra as the second battery. That could be a happy compromise if you really want to save money. For Wedding Videographers
