Mirrorless Digital Camera Accessories

The point of some mirrorless camera accessories is to add on features that are left off the camera body to reduce size and weight.

Others just make your camera that much cooler.

The amount of use that you'll get out of an accessory depends a lot on how you like to use your camera. For example, an external microphone is really only useful for people who want to take LOTS of video with their mirrorless digital SLR.

Types of Accessories

Let's break down some of the different types of mirrorless digital SLR accessories:

ACCESSORYDESCRIPTION
BatteryOne is always provided with the camera - but an extra is handy to have around when the primary runs out.
Memory CardThese are NOT included in the typical camera kits, so you'll have to purchase one separately.
ViewfinderSome mirrorless cameras don't have a viewfinder to look through if you can't see the image on the LCD, so optional electronic viewfinders are available.
FlashIf your camera doesn't have a built-in flash, then you'll need this accessory for low-light photography.
MicrophoneEvery camera that captures video has a built-in microphone, but if you want better audio quality this is the thing to have.
Underwater CaseIf your passion is taking pictures 20 feet underwater, then a case like this is essential.

With the exception of batteries and memory cards, not every accessory is available for every camera - it's sort of a mix and match approach.

Start out by finding the right mirrorless camera, then take a look at the accessories that go with it.

Batteries

Every mirrorless digital SLR gets its power from special lithium-ion rechargeable batteries.

The bad news is that these batteries take several hours to charge and you can't just use a few regular AA batteries while you wait.

The good news is that the power in these batteries holds up quite well, lasting through a week of solid shooting. If you're not taking pictures every single day, then a full charge will last you longer.

Here are the current mirrorless digital SLR cameras and the batteries that they use:

Memory Cards

Since memory cards are NOT included in standard mirrorless camera kits, you'll need to purchase one separately.

All mirrorless cameras are compatible with standard SD and SDHC (High Capacity) memory cards. A few are also compatible with the new SDXC cards, which provide even MORE storage for those who want to take lots of video.

Memory cards come in different "classes": you'll want to look for class 6 cards, since these have faster read/write speeds than their class 4 alternatives.

If you just intend to take photos with your mirrorless camera, then capacities between 4GB and 8GB should provide you with plenty of storage space.

Aspiring movie-makers will want to investigate the larger card sizes, since video eats up card space like a rocket burning through fuel.

I come from the camp that believes that it's better to have several smaller-capacity cards rather than one card with tons of storage. The thinking here is that if one of your cards fails, then you don't lose EVERYTHING all at once.

The flip side is that your cards fill up faster and you have to swap them out more frequently, but this seems like a small price to pay to protect at least some of the images you capture.
