Hi everyone. New poster here. I was turned on to this forum by someone who just purchased a lens from me. Seems to be a lot of good information and images here and I would love to add to that. I thought I would start of with some examples of what I have been able to pull out of the Metabones Contax/Yashica Speedbooster recently. While I am a big fan of Minolta Rokkors the fact that Metabones has not released a speedbooster for them made me go back to my old love of Tomioka made Yashica glass from the time they were producing the Yashica lenses for themselves and the Zeiss lenses under licences. There is something about the bokeh from old Tomioka glass that I find to be very special and pleasing. So here is a link to my speedbooster page on flickr. Speedbooster - a set on Flickr A good thing about the C/Y speedbooster is you can use a C/Y to M42 adapter to get old screwmounts on there as well. Some of the shots are from old Zeiss Biotars and Flektogons, as well as a couple of old Tamron Adaptalls. Anyway, I hope you enjoy. Here are a few samples of whats in the folder.
