This article discusses the different types of light bulb bases. It broadly covers what the different light or lamp bases mean, why different lamp bases are used for different lighting applications, and where those light bulb bases are used. Additionally, it provides a light bulb base sizes chart in shareable image format. Light Bulb Base Sizes The most common type of base is the E type. The E stands for Edison and indicates that the base is a screw type. The size is a simple millimeter measurement of the width. Again, while the ZV-E1 is designed for video first, it can still take photos if you like, albeit at a maximum resolution of 12 Megapixels, such as these examples. Further cementing its intended use for video, Sony’s also seen fit to remove the mechanical shutter on the ZV-E1, so unlike the S III, you only have a fully electronic shutter for still photos.

The three most often used bases in the United States of America for traditional lighting are the E12 (candelabra), the E26 (medium), and the E39 (mogul). Light Bulb Base Sizes Chart In Canada, vehicle headlamps may use light sources (bulbs) conforming to either the US or the international ECE regulations.

Ok, now for the sensor which as you already know is inherited from the A7S III. This has 12 Megapixels which in turn allows the ZV-E1 to record 4k video without additional cropping, binning or oversampling. It simply slices-off the top and bottom into the 16:9 shape and starts recording. However you choose to describe it, the ZV-E1 is unashamedly aimed at videographers. Sure it can still take photos, but this is not designed as a hybrid camera. If photos and video are equally important to you, you’ll be better-served by the similarly-priced A7 IV. There are dozens of different light bulb bases. The most common is the Edison screw base, which may be found on most incandescent bulbs and many halogens, compact fluorescents, HIDs, and now LED lights. Edison Screw Bases E11 and E12 are not interchangeable because of their different size. Does the Bulbs Base affect voltage and performance?

While electronic shutters have the benefit of silent operation, they can suffer from artefacts including banding under artificial light and again skewing from rolling shutter. Like earlier ZV cameras, the E1 is also supplied with a wind muffler that slides onto the hotshoe. Sony supplied my test sample with the version for the white body but the effect is the same. In my video review above, you’ll hear how the modes compare, starting with the mic set to front, but initially without the muffler, so you’re going to hear some wind noise – don’t worry, it won’t be for long.E39 is known as the large base or mogul base. Its typically what is used on older metal halides and high pressure sodium from 100 watts and up. The E is for Edison screw base and the 39 is 39 mm across. Larger than the standard E26 or 26 mm across. Next here they are with Active SteadyShot, making the 28 on the right uncomfortably close, and finally here’s both with Dynamic SteadyShot, delivering the least wobbly footage, but with the greatest crop. I enjoyed the new modes, especially auto framing whether the camera was on a tripod or handheld, but it’s a real missed opportunity not to offer a vertical crop option.Imagine being able to record horizontal and vertical versions simultaneously, with the camera automatically keeping the subject centered on both. This could be even better still if Sony equipped its cameras with Open Gate to access the full height of the sensor. Next for Active SteadyShot which again applies a crop to allow the sensor shift system to operate over a broader range. Browsing the online shop you’ll need to look in the product’s description or specification for the code used to describe the cap of the bulb. For screw in fittings it will start with a letter ‘E’ which stands for Edison Screw. The second part will be a number which corresponds to the diameter of the lamp holder the bulb’s screw goes into, so an E10 screw fits in a 10mm diameter holder, an E14 screw fits into a 14mm diameter holder and so on…
