OKay now that I have decided to make the jump backwards... It is really between the rollie and yashica twin lens but I want to test the format to be sure it is worth the effort..... sooo.... The best test camera I can find so far is the revere eyematic 127. Its a fifties type auto aperture but it has a wallensak lens and a rangefinger. Looks like even a way to fool the meter for a little more exposure. Since it has a tripod socket, I assume there is a way to jury rig it to do bulb. With the polaroids I play with it is just put some tape over the sensor. All that being said, has anyone ever heard of this camera. If so what have you heard. I saw some things on google and some pictures made with it and they look okay nothing to brag about but okay.
