Fast 50s Compared

7/17/2017

0 Comments

 
This video is about Fast 50s. We were curious just how sharp all of these lenses were in the center and the corner. The 50s were put into two different groups, first the fast group. 7artisans, Mitakon Speedmaster, and the Canon 50mm/1.2 L. Then we added the Leica 50/2 Summicron and Zeiss Loxia 2/50 and compared them against the entire group. Our test cameras was a Sony a7.

What we found was the Mitakon Speedmaster was the sharpest in the center within the fast group. The Canon was sharpest in the corner from the fast group. When looking at all five lenses as one group, we believe the Leica is the sharpest both at the center and the corner. 

Watch the video and let us know how you believe we interpreted the results. We want your opinion.

Download the RAW files at the bottom of this post. I had to split the files into three folders to keep each ZIPed folder under 250mb each.

7artisans 1.1/50mm for Leica M Mount

7/12/2017

After shooting nearly two weeks with the $369 USD 7artisans 1.1/50mm leica M mount lens, I give my thoughts on the lens along with RAW files for you to download.
The lens is soft wide open at 1.1 but this is not really a surprise. Most big aperture lenses are soft wide open, this lens is a little more soft wide open than you will see with a Zeiss, Leica, or Canon. It is a compact, light weight lens that offers big aperture for little money (relatively speaking). The focus through has a little bit of play in when switching directions with the focus ring. It is enough for me to notice but not enough for me to be angry about (see low price above). 

All in all, it delivers good images in most situations and would make a great first fast 50mm for those who are not afraid of manual focus. If you already own a Voigtlander Nokton or Mitakon (Zhongyi) Speedmaster 0.95/50mm, you don't need to trade your lens in. I would take both of those lenses over the 7artisans.
