Is Sony A7 III the Best Mirrorless Camera for Trekking?

by | Gear Explorer


Is Sony a7 III the best mirrorless camera for trekking? Oh, who knows. But it’s certainly one of the best full-frame mirrorless cameras to take in a trekking adventure. While DSLR cameras offer more lenses, accessories, and tend to handle low light better, mirrorless cameras are lighter and better for videos. For those who do not want to take the burden of carrying a DSLR camera while hiking, camping, and so on, Sony a7 III is one of the mirrorless cameras that must be considered.

It has often been said that Sony a7 III is particularly suited for most of those who are interested in landscape and nature photographers. In other words, unless you are a professional that is looking for particular features that you believe are necessary in order to make the best nature and landscape picture, it is very likely that you will be highly satisfied with this camera’s features, including its 24.2-megapixel sensor.

What I like about it:

• 14-stop dynamic range

• 10fps burst shooting

• Uncropped 4k video

• The performance of the electronic shutter

What I don’t like:

• Fairly limited touchscreen control


While the 24.2-megapixel sensor is significantly less appealing than what you can get with other high-end cameras such as Canon 5DS R in terms of resolution, it can still cover the needs of most trekkers that want to capture views in a fairly scenic way. For instance, you will probably find the 10fps capture rate offered by the camera very satisfying, as well as the ISO range of 100-51200 and the dynamic range of 14 bits.  The 14 stops of dynamic range are well-suited for high-contrast scenes, which should be very helpful in many landscape pictures. The a7 III offers some of the best dynamic range in the class and can make a serious case against the use of a DSLR. The performance of the electronic shutter is modest, as distortions can occur when shooting fast-moving objects.

Sony a7 III is also a fairly good camera for taking videos. The camera provides full-frame, non-pixel-binned 4K videos and can record at 100 Mbps. The EVF can be challenging, as determining critical focus on it without zooming into a subject is not particularly easy. Perhaps you are up for a challenge.
