Landscape astrophotography is something I have been doing for several years. Luckily over the past few years many lenses have been released that make this task easier than ever. So today we are going to have a look at all the available lenses for your Sony so you can choose the one that works best for your needs.

What is landscape astrophotography?<\/h2>\n

In landscape astrophotography you will usually try to have a combination of the starry sky (with Milky Way or Northern Lights) as well as some foreground (e.g. landscape) in your frame so we are mostly looking at ultra wide to normal lenses (for stitching) here.<\/p>\n


\nI am not going to talk about deep sky astrophotography, this is a field I have very little experience in and you will need completely different (longer) lenses and rely on a guidance system most of the time.<\/p>\n

What lens characteristics are important?<\/h2>\n

Generally a wide<\/strong> and fast<\/strong> lens makes life easier for us, but the lenses also need to be good<\/strong> wide<\/strong> open<\/strong> with somewhat decent<\/strong> corner<\/strong> resolution<\/strong> and coma<\/strong> correction<\/strong>.
\nThis rules out pretty much all old legacy lenses.
\nIt would also be nice if the lens has low vignetting and if it can easily be focused manually, as we can’t rely on autofocus<\/strong> at night.<\/p>\n

A few more notes on the lenses I am going to introduce:<\/p>\n
