The finder of the camera is very bright, hence "Brilliant" in the name, but I am more interested in the lens, which is easy to remove by unscrewing the retention ring; it can be put back just as easy. I found some parts that I can put together and mounted the lens on my Yeenon Helicoid. Looks ridiculous, but works :)
Naturally, for a small aperture lens, it's only suitable for daytime picture taking, if you want to shoot handheld. The lens has its own focusing mechanism, and because I put the lens on a focusing helicoid, which allows me to focus very close if I use both focusing rings.
The lens turns out to be quite brilliant. Very pleasing rendering of pictures and nice bokeh, and it's also very sharp. The most surprising thing of all, especially when compared to its sister lens, the 8.3cm f4.5 Skopar, flare is well controlled if being careful. In fact, I didn't even use a hood for all the pictures below.
The greatest fun is making the lens to work with a modern digital camera, and the quality did not disappoint. Even if I only use this lens just once, it's worth the $20. How much fun can you buy for $20 these days :)
