Those are some great preview shots, thanks! 50/55mm (Fujinon 55mm f/2.2) is one of my preferred focal lengths on APS-C; I started with 50mm. Your samples have a look distinct from the EF 50mm f/1.4 and also from the Fujinon M42 lens (a non-multicoated version). I have seen a couple other sample images which highlight some of the possibility of somewhat odd renditions with this lens, but in your samples you've definitely brought out the good in the lens. The somewhat orange tint to some of the pictures also resists being classified as "dated," instead looking like just a great photo.
It does seem like out-of-focus backgrounds can have a sort of "spherical" look to them (as seen here) but it's probably no big deal.
Thanks! Glad to know those were helpful to describe the lens.
Yes, the out of focus backgrounds can have a spherical, slightly intensified or differently-colored edge to them, almost like the beginnings of a coffee stain. It seems to pretty much go away by f/1.4 or f/2. It's not a hard and fast rule. Some subjects bring it out and some don't. Anyway, most of the time I find the effect can be rather pleasing.
I created another forum post under "Image Gallery \ Lens Gallery \ Canon FL 55mm" with some more photo samples.http://www.canonrumors.com/forum/index.php/topic,1758.0.html
Hopefully some other people will post theirs as well.
I'd get a katzeye based on the limited research I've done.
Thanks, the Katzeye is what I had been leaning towards getting installed. I suspect having a good split prism focusing screen could be the final key to making this lens really perform.
