There are cameras
-) that seem real refined and well finished, but nevertheless fail soon due to some construction fault
-) that seem were crude designed and fiinished, but still go for a very ong time
-) that fail the more soon the more crude they look
I've run a Seagull 4A103A TLR for more than 20 years and it is a reliable and rock-solid performer. Even the triplet taking lens is gratifyingly sharp at f16, gratifyingly smooth at f3.5 BUT:
I recollimated the focussing system which was remarkably erroneous ex factory.
The wind gear has been rebuilt the way the designer intended.
The shutter and the shutter cocking system has been tweaked into reliability.
My impression is that the Seagull is a Rolleiflex copy made of strong but crude parts that have to be carefully bent, filed, and twisted to work properly against each other. Once done all is well. I'd say at the factory production targets probably demand that cameras are built in a hurry by people who do not check their work.
How about some sample pics Robert? After that review, we're all ready.
