<p>Hello,<br /> So I just bought an almost mint condition Minox 35 GT-E in original case and cardbox. Even the original batteries seem to work correctly. Everything seems to work and is intact.<br /> Except when I tried f2.8 and f16 and don't see the blades open and closing :(. This should be the case, right? <br />When I take off the back and make a test shoot I see the shutter is working. With 2.8 the shutter is quicker and with f16 the shutter takes longer, but the blades seem to stay the same.<br /> Any advice? Can I fix this by opening the lens? If so how?<br /> Happpy shooting and a great weekend!<br /> regards,</p>
