>>3118301Make sure the shutter works, the electronic shutter can be finnicky and fails occasionally.
I'm also using tape on the viewfinder like the post below. Helps with focusing a whole lot.
>>3118582The lens might not be as sharp as the minox 35, however with the rangefinder the chance of you nailing the focus in the first place is much higher. It's a great little camera that's also got the benefit of being more or less completely silent. You can also modify the iso-dial to do exposure compensation on the fly.
