Review: Sony FE 100 f/2.8 STF GM OSS Lens

Introduction:

The Sony FE 100 f/2.8 STF GM OSS lens is a lens that I purchased some time ago not really knowing what to expect. I had read about the lens, of course, but frankly I found that it took me some time to get an understanding of how best to use this lens. I think it is a very fine optic with excellent sharpness and anextraordinarily smooth quality of bokeh, however, it is also a lens that imposes a steeper than normal learning curve.  It has a distinctive look in some situations that seems to be polarizing in the photo community.  With use, I have come to like this lens very much and don’t plan on parting with mine anytime soon.  In this review, I will attempt to explain why I like it and also some of its quirks so that prospective buyers might have a better idea about what to expect.

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.

Many people are still looking for a small yet fast 35mm lens for their fullframe E-mount cameras (especially those who need AF). I have found what I am looking for in the Voigtlander 35mm 1.7 VM + 5m PCX filter, but many people don’t want to bother with this mod and prefer a native solution. So how does the modded 35mm compare to Voigtlander’s native 40mm 1.2 Nokton E?
