You may have already heard of sample variation or decentered lenses. In this article we will show you how to easily test your lenses for proper centering. If you know how it works it will take you less than 5 minutes per lens!
After I tried the Visionar 109mm 1.6 I became quite interested in this line of projector lenses as they offer quite a lot of glass for the money. The 168mm 1.9 is the third longest of the line. It is quite a bit ligther than the two longer ones, so is it a good compromise?
Brenizer or Bokehpanorama is a panorama technique to get a wide angle shot with the much better bokeh of a longer tele lens. In this article I will show you what it is all about and which lenses work best.
What is a Brenizer/Bokehpanorama?
By using longer lenses and taking a panorama you can simulate the look of fictional, wider, very fast lenses that are not even technically possible to build.
Landscape astrophotography is something I have been doing for several years with my Sony a7S and a7rII (and D800 before). 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?
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.
The Visionar 109mm 1.6 is a cinema projector lens from Carl Zeiss Jena which was made in the GDR. These projector lenses are often very fast and cheap, but they also come with a few downsides. This is the first projector lens we will review at this blog, so find out if there is still a place for these today.
