Well.. Good question.. My first one was Lubitel 166.. I got back 3 broken lubitels from my last trip to Ukraine and made one working. After first successful 120 film developed, I immediately purchase Yashica A in like-new condition. That was start of my new passion. Next one was ugly broken Mamiyaflex that I fixed / partially restored. Then broken Zeiss Ikonflex with Novar and rusty shutter. I fixed that one, too. I really wanted to try zeiss "magic" lenses and I was not disappointed. Super sharp with nice bokeh. After reading few posts about Yashinon lenses and their possible relation to Zeiss I got Yashica 124 with broken meter that was fixed as well. At this moment I have 2 Zeiss Ikonflex TLRs, Yashicas A, E, EM, 124 and 124G, Lubitel 2, 2 x Lubitel 166, and my last purchase, Ricohflex Dia.
Few weeks ago on my trip to LA I met guy on Santa Monica Pear walking with his Rolleiflex while I was taking pictures with my Yashica EM.. Now it looks like I will sell almost all of my TLRs and will try to get that nice German camera..
So this is my story. Maybe it is important to add that I developed my first 120 film only 3 months ago...
